Some useful information about video intercoms

Standard video intercoms for an apartment consist of a calling panel with a built-in CCTV camera and a monitor, which is installed directly in the apartment. But the situation can be complicated by the fact that you will have to purchase a video camera specifically for the entrance, if it is not already installed, spending your personal funds.

You will also need to connect:

• Monitor for the calling panel on the entrance door and, if available, for the entrance camera.
• Connect to the unit with the monitor the calling panel at the apartment and the calling panel at the entrance door to the entrance.
• It may be necessary to connect an outdoor panel with an electric lock to several units with a monitor. This is done if there is a vestibule for several apartments.

It is very difficult to directly recommend any specific model of video intercom for an apartment, and it does not make sense. It is better to analyze all the important points point by point and in the end the buyer himself will be able to make his choice, thanks to the useful information presented in this article.

Scheme for connecting an apartment video intercom to a common entrance

Reading time: 6 minute(s)

Video intercoms have become common household amenities designed to improve comfort. Demand is growing - supply is expanding.

Sometimes it is difficult to figure out without an expert how to connect a video intercom to an entrance intercom. It is necessary to learn the intricacies of connecting to the network and comply with installation requirements. A new connection, as well as replacement of the kit, is made in accordance with the instructions.

What is a system for combining an apartment video intercom with a general one?

Apartment and entrance intercom can be combined and synchronized operation can be established. Two problems are solved at once.

The device receives calls both from the front entrance and indoors.

Before purchasing, you need to know the model of the intercom at the entrance. Video equipment is selected for the initially combined equipment, which allows the use of several calling panels and video cameras.

To connect a video intercom to an entrance intercom you will need:

• Video intercom;
• Call panel;
• Video camera for the apartment;
• Video camera at the entrance to the entrance.

The key element for consistent incoming calls is the interface unit, module or adapter. If this function is not available in the intercom, the device must be purchased separately.

A video intercom is installed instead of a handset.

The calling panel shows visitors and at the same time performs the call function. The equipment consists of internal and external parts.

• Internal - installed in the apartment.
• External - in the entrance, has a calling button, a video camera with LED lighting.

The general movement on the street in front of the entrance is visible on the monitor. When illuminated at night, a person's face can be recognized at a distance of up to one meter.

Adapter selection

The adapter is the connecting link between the apartment and the entrance. It must be compatible with one and another intercom. Only if there is compatibility, trouble-free operation is guaranteed.

Before going to the store, you will need to collect complete information about the intercom at the entrance door.

The kit is taken for specific purposes and tasks:

• Reception of several video cameras when additional review is needed;
• Setting the signal distribution mode for several subscribers;
• In some situations, the installation of an amplifier is required.

It must be taken into account that most intercoms have galvanic isolation or dampers to stabilize audio communication to eliminate interference.

A correctly selected device instantly transmits a signal, identifying an object. Otherwise, the adapter may turn out to be a useless purchase. The video camera will not turn on, and the sound quality will leave much to be desired.

Selecting an interface module

The block is selected based on the following criteria:

• Availability of galvanic isolation. The characteristics of electrical circuits must comply with the parameters;
• Block type: MSC or MSC.
  The pairing has distinctive features according to the equipment used. The MSC has an additional function for connecting a separate apartment.
• Type of installation. Internal work involves installing a video intercom for all subscribers at the entrance. External installation provides for video signal transmission for one subscriber.

Basically, external installation is used. Installation is carried out in a low-current panel.

Connection diagram of a video intercom to an entrance intercom

To connect to a common intercom, you need to replace the audio transmission line from the intercom handset with a video cable.

The first calling panel is located in front of the entrance to the premises, the second panel is multi-apartment. The stages of work are carried out in the most convenient way.

There are several options that are used in practice. The ideal case is when during construction a socket box was installed, from which low-current cables come out.

Usually, twisted pair with or without a screen and a 220 V power cable.

• The ends of the wire are ringed, stripped, connectors are connected, inserted into the video intercom, soldered and insulated. The wires from the apartment and the entrance are connected to the coordination board.
• One of the wires is led out to the calling panel into a low-current niche in the apartment.
• The second wire is directed into the riser on the floor, where it is connected to the multi-apartment intercom cable.

Details:

• The 12 V terminals are designated by numbers: 1,2,3,4.
• The cable from the entrance intercom connects to them.
• The street block also has a terminal block.
• The cable cores are connected in accordance with the numbering: 1-1, 2-2, 3-3, 4-4 in the same way, both indoors and outdoors.

1. Stage 1. Connecting a pass-through group using a video intercom, calling panel, magnetic lock and controller:
   The two blocks are connected to each other by a four-core cable;
2. At the location where the calling panel is installed, two holes are pre-drilled, dowels are inserted and the wires are stripped;
3. To ensure that the calling panel fits snugly against the wall, a hole punch is made in the wall for the wires;
4. The calling panel is connected via wires and mounted on the wall.
5. Stage 2. Connecting a video intercom to a video switch:
   The video signal is connected to the common house coaxial wire.

   An adapter is connected to the low-current connection from the apartment.

   One part comes from the video intercom, the second part goes to the common cable in the entrance from the video and audio signal.

   • The wires are laid in the socket box. The ends are left no more than 10 cm so that everything fits into the recess;

   Power from the intercom in the room is automatically connected, loading is in progress, and the functionality of the panels is checked;

6. If the kit comes with a memory card for saving photos and videos, the card is inserted into the side slot.

After connection, the equipment is tested.

The panel is displayed at the entrance and in front of the apartment. The button in the menu changes the ringtone, mode, color, brightness, files with images and captured frames are viewed.

Installation example

1. The video cable is being laid;
2. A call block and a rotary bracket are installed at the door to the apartment;
3. The wires are connected to the cable;
4. A calling panel is installed on the wall;
5. The ends of the cable from the call panel and the power cable from the monitor are led into the apartment for installing the screen;
6. The mount for the monitor is installed and the wires for connection are stripped;
7. The monitor is installed and connected to the call switching unit in the entrance;
8. The matching unit from the monitor is connected to switching equipment and connected to the entrance intercom.
9. In operating mode, an approach camera will be visible on the screen. By switching the button on the monitor, the image from the call block will appear.

The connection depends on the type of intercom: digital or coordinate.

The first option is more expensive, there are more possibilities, but you have to periodically reconfigure it.

The more common second type is cheaper. The tubes operate autonomously and are separately connected to the control unit.

In practice, the most common option is a two-channel video intercom with the connection of two calling panels simultaneously with two rows of screw terminals.

Connection with electric lock

To correctly screw the wires, a numbered hint is given.

The connection is made using color combinations and indicators. There is a marking on the wire that identifies the connection points for video, audio, power and control:

• 1 - audio from the call panel:
• 2 - general nutrition;
• 3 - plus 12 volts;
• 4 - video signal.

The calling panel is connected to the second row of screw terminals.

The intercom allows you to control an electromechanical lock.

• One of the wires is connected to the electric lock,
• the second end is connected to the power supply.
• The second one is led from the power supply to the electric lock.

The visitor in front of the train presses the button on the calling panel and an image appears. After the conversation, press the button on the intercom to open the electric lock.

The second panel is connected in the same way.

Control is carried out simultaneously by two panels and two locks. One panel is installed at the entrance, the second - at the entrance door.

Other options:

• Instead of two electric locks, one is sometimes used or dispensed with. Then the two wires leading from the calling panel to the electric lock are isolated and not used.
• There are options when, instead of one of the calling panels, a regular video camera is used: Pressing the button on the intercom once switches to the first calling panel.
• The visitor is communicated through a handset using an audio channel.
• By pressing another button, the second channel is selected and the image is viewed.

This connection is convenient to use in long narrow corridors.

• At the entrance there is a door with a first calling panel and an electric lock.
• The visitor presses the calling panel, after a conversation the lock opens.
• A visitor walks down the corridor.
• Switching to the second video channel, the signal from the video camera installed in the corridor passes through.

If you do not connect the calling panel, camera, or electric lock to the second channel, the intercom will work like a regular single-channel one with one calling panel.

The cost of the master's work

The more functions and types of work there are in the intercom, the more expensive the services. The main factors that influence the price of installing an intercom:

• Nature of work;
• Connection type;
• Region of service provision;
• Intercom manufacturing company;
• Brand of installed equipment;
• Number of apartments connected at one time.

Each company that installs video surveillance develops and approves its own prices.

After agreement with management, customers are provided with a price list. The final price is the sum of all work performed.

Types of video intercoms for apartments

Of course, it will be easiest for owners of apartments in new buildings. In such houses, cameras are immediately installed at the entrance and special calling panels at the front door of the house. Residents can only connect to existing equipment and purchase an additional calling panel for their apartment and a monitor for the room.

For owners of older houses, installing a video intercom will be a little more difficult and costly, but nothing is impossible. Let's look at the main types of video intercoms. Perhaps this information will help you save money.

Which intercom to choose

There are many companies on the Russian market that manufacture devices for intercoms. High production technologies allow us to produce improved models every year. What kind of intercom system there will be in the house is up to the owners to decide.

When choosing an intercom, you should pay attention to the switching system. Based on this parameter, coordinate and digital intercoms are distinguished. Their difference lies in the wire through which the connection to the apartments is made.

When installing a digital intercom, one line is laid to connect the switch with all apartments. The coordinate system is designed in such a way that each apartment will have a separate wire connecting it to the switch.

Today, digital intercoms are considered more reliable in operation. But their price is three times higher than the price of coordinate ones.

Another characteristic worth paying attention to is the type of connection. There are audio and video intercoms. The difference between them is the presence of a display on which you can see who is calling. The video intercom provides high security; thanks to it, no strangers will be able to get inside the entrance. But the cost of such devices is high. Apartment owners for the most part give preference to audio intercoms.

Who pays for intercom service

From the moment of installation, the intercom acquires the status of common property and belongs to all apartment owners in the building. According to current legislation, the residents themselves pay for the maintenance and upkeep of the property. After the intercom appears at the entrance, a new receipt will appear in your mailbox.

The obligation to pay amounts for the maintenance of this device is also assigned to those owners who did not install tubes in their apartments.

Previously, people did not think that someone could enter their entrance and cause damage to the property located in it. In Soviet times, there were wooden entrance doors, and flowers in pots bloomed on the staircase landings.

Perhaps the reason for the vandalism of the entrances was the dashing 90s, when the morality of the people wanted better. That’s when they began to come up with and install various means of protection from ill-wishers. At first these were combination locks installed by housing and communal services, then they were replaced by intercoms. Let's see what else they will invent to protect common property.

Analogue video intercom for apartments

The transmission of audio and video signals in such video intercoms occurs via an analog cable. The price of analog models is not high and connection is not difficult in a Russian high-rise building. Analog video intercoms are easily combined with calling panels from almost all modern manufacturers.

Connecting an analog video intercom via an interface unit to a regular audio panel and a video surveillance camera on the entrance door is very simple. At the same time, you can choose a modern touchscreen monitor and a hands-free one. We choose what we like. There is no need to buy outdated models or models with a tube.

Which cable to choose for connection in a high-rise or cottage

For video intercoms, it is preferable to use a conductor of the ShVEV and ShVEP types. It is a sealed shell with separate lines for the lock, video signal and audio communication.

Main characteristics: characteristic impedance 75 Ohm, thickness within 1.5 mm, copper central conductor and braid.

Digital models of video intercoms

Digital video intercoms use either a network cable to transmit audio and video signals, or do not use wires at all. Such devices have good sound and image quality. It will also not be difficult to connect such a video intercom to the smart home system. Sound and image transmission in digital video intercoms is carried out over a network or via a Wi-Fi network.

It is worth noting that digital video intercoms have higher prices compared to analog models. Setting up such video intercoms is also not easy, and the most important thing to remember is that digital models cannot always be combined with conventional calling panels.

Digital is the best intercom for a country house or for an elite apartment in a new building. Since connecting and operating the device will not be difficult for the owner. For an ordinary apartment, installing such a video intercom will cost a pretty penny.

Multi-apartment video intercoms: direct call, digital, connection diagram, areas of use

The type of device is selected depending on the number of residents in the entrance and the degree of protection desired.

Direct call video intercoms

The device can be single- or multi-subscriber. On the panel there are buttons with the numbers of each apartment. An important advantage is the ability to initiate communication from home.

Such equipment is usually installed in private properties or club houses with a small number of floors.

Digital modular video intercoms

The panel is equipped with 12 buttons for connecting to apartments. You need to dial the digital code and click on “Call”. But you won’t be able to initiate communication from within.

Depending on the additional built-in modules, the functionality expands, the following appears:

• viewing pictures from the camera, list of subscribers;
• communication with the concierge;
• entrance by electronic card.

For example, a Samsung apartment video intercom can be equipped with a digital concierge switchboard function. Communication between guests and hosts will be through a third party.

Installation of a video intercom in an apartment building is carried out according to the following scheme:

1. Drill holes on the inside of the entrance wall to install the calling unit and lead out the wires.
2. Make a recess in the door trim for the back of the video intercom housing.
3. Secure the electric lock and lead the power wire into the entrance.
4. Install the compositor, make openings in the ceilings between floors and stretch the cable.
5. Mark the installation location of the device on the wall in the apartment, drill a hole for the video intercom wire and stretch it to the stairwell.
6. Supply power to the call block located at the entrance door.
7. Connect the terminals to the signal cable, and it, together with the electric lock, to the calling panel.
8. Start the system, check the operation of each street intercom button.
9. Program the call block for the keys of all residents.

Only after checking the correct connection and communication of the device with each apartment can you bury the wires in the wall.

Video intercoms with recording

Some analog and digital intercoms for apartments can support the function of recording a video call and audio conversation with a guest. This fact makes such models full-fledged video surveillance devices.

Most often, this intercom also allows you to view video files and listen to video directly on the monitor.

Analog models typically save media files to a microSD card. This is not always convenient, especially if the memory card capacity is limited by the technical parameters of the device. If the memory card is full, you must either clear it or reset it and save the footage to your computer.

Digital models of video intercoms are much more convenient in this regard. The device can be configured so that captured media files are automatically saved to a file service. Or, for these purposes, you can use the “cloud” on special sites via the Internet. In addition, digital devices allow you to broadcast by forwarding to a mobile phone or tablet. However, the device must always be connected to the Internet. Via mobile communication or via Wi-Fi.

Scope of application of video intercoms

The exact composition of the necessary equipment depends on the intended purpose. Common use cases are discussed in detail below.

Models of intercoms with video surveillance for apartments

Set for six apartments

The easiest way is when collective equipment with electronics is planned (at the stage of construction, major repairs, modernization). In this case, purchase a set with one input unit and the required number of subscriber devices.

It’s more difficult when a common intercom is already installed at the entrance

In this case, you need to select a model that matches the existing equipment. To coordinate components of different brands, specialized transition devices and adapters are used.

Video intercoms for a private home

This project is easier to implement since I have to connect to public equipment. In this case, the owner himself decides which model of video intercom for the apartment is suitable for him. But in addition to the advantages, there are difficulties. We have to lay long communication lines between the house and the gate in the fence.

This problem can be simplified using wireless information transmission lines

For your information! If the external unit is capable of operating via a Wi-Fi channel with an Internet connection, it is acceptable to use a smartphone or tablet. These mobile devices are quite capable of replacing a specialized video intercom receiving unit.

The need for additional protection arises for many homeowners who want to limit access to their site. One of these means are video intercoms for a private home . Let's talk in more detail about these devices, their types and technical nuances of installation.

Office models

This option assumes the presence of a stationary workplace (janitor, secretary). Quite often the system is combined with video surveillance and security systems.

The image from several cameras can be displayed on a large screen of a specialized or universal computer monitor

A high-quality household video intercom for an apartment with an entrance block is designed for intensive use. It can withstand commercial loads. Therefore, when equipping offices, it is quite acceptable to use standard general-purpose models.

Video intercom models with call forwarding capabilities

Analog video intercoms can be connected to each other in an Intercom network. Typically, manufacturers immediately write how many monitors can be combined. Intercom requires the additional installation of a special SIM card and the installation of incoming call forwarding.

Digital devices transmit incoming calls over the Internet. For this, a special application is usually used, which works with both the Android and iOS operating systems. The application can be downloaded from special services or can be provided by a supplier of intercom equipment. So, thanks to a digital video intercom, you can view video from surveillance cameras or a calling panel in real time. You can also open the door remotely or talk to the visitor.

Connecting an electric lock to a video intercom

When installing a personal video intercom in an apartment or private house, special attention is paid to the possibility of remotely opening the front door or gate.
For this purpose, an electric lock is connected to the main unit, which can be opened by pressing a button from inside the room. A person authorized to enter the premises may open the lock in any prescribed manner. Connecting a video intercom with an electric lock can be done either wired or wireless. In order to carry out this work correctly, you need to decide on the type of electronic lock and its design. Content:

Types of electronic locks

All electronic (electric) locks can be divided into two groups:

• Electromagnetic locks;
• Electromechanical locks.

Any type of electronic lock can be connected to a regular intercom or video intercom, and the choice is determined by the design of the door and the functionality of each design.

Electromagnetic lock

The lock of the first group is a powerful electromagnet, which is constantly supplied with low-voltage power from a separate source. This design is mounted on the door jamb. The second element of the lock is a metal plate made of a magnetic alloy, installed on the door leaf. In operation, the door is closed, the door plate is pressed against the magnet and is held in place by the magnetic field. In order to open the door you need to press the button on the subscriber unit. The electromagnet will be de-energized for a short time, sufficient to open the door and enter the room. The door closer will then close the door and it will be locked again.

Scope of application. An electromagnetic lock is most often used in office and industrial premises, which are separated by metal-plastic doors. Such locks are not intended for the use of mechanical keys, and in order to open the lock from the outside, a visitor with access rights can use an electronic “Touch Memory” key fob or a magnetic card. To do this, a card reader or code reader from an electronic key is installed on the outside of the door jamb. The wiring diagram for an electric lock of this type is not very difficult.

The electromagnetic lock has the following advantages:

• Low cost;
• Easy installation;
• Installation on various types of doors.

Flaws. The disadvantage of such a system can be considered the dependence on a constant supply of supply voltage, since if the network goes out, the electromagnet will be de-energized and the door will be unlocked. According to experts, this disadvantage becomes an undoubted advantage when, in the event of a fire, the entire building is disconnected from the power grid and open doors facilitate the rapid evacuation of personnel. In addition, such systems are poorly protected from intruders.

Models of video intercoms with support for motion sensors

Nowadays, video intercoms with motion sensors are considered especially popular. When recording from the camera is carried out only when an object appears in the field of view of the sensor built into the calling panel. This allows you to record while saving space on your memory card or server.

In addition, there are models with a built-in sensor into the monitor itself. This device works as follows. As soon as the owner approaches the monitor, when an incoming call arrives, the video intercom turns on the sound and video. In this case, the apartment owner can use voice control (Hands Free) to answer the call or ignore the call and just look at the guest or take a photo of him.

Video intercoms with a built-in motion sensor do not require handsets or buttons to control an incoming call. So you just need to say a voice command and the device will carry it out.

Intercom Visit - detailed connection diagram

The operating instructions for the “Visit” intercom must indicate safety precautions. It must be remembered that the voltage in the device does not exceed 18 V. It is strictly forbidden to carry out maintenance or repair of the equipment while the power is on.

Repair work or routine maintenance must be carried out by a specialized service organization. The instructions also describe the installation procedure. Before performing installation work, be sure to study it, as well as the connection diagram of the intercom equipment units.

The instructions contain a graphic representation of the device installation process. Direct contact of snow or rain with the external call unit is not allowed. It is prohibited to use electromagnetic locks with a resistance lower than 10 Ohms and higher than 20 Ohms.

The operating instructions must include a description of the technical parameters of the intercom device:
1. power supply voltage;
2. power consumption;
3. dimensions of the calling unit (dimensions);
4. block mass;
5. operating conditions (minimum and maximum air temperature, relative humidity).

If a video intercom is installed, then the camera parameters must be indicated.

Models of video intercoms with electric lock

Such video intercoms communicate not only with the entrance door, but also with the individual door, for example, in private houses or vestibules. This way you can control an electromechanical lock using a video intercom by pressing a button.

In this case, the video intercom monitor allows you to further simplify the security task. You don't have to open the door manually. All you need to do is press a button. This additional feature is very useful for high-rise buildings with vestibules. In this case, you will not have to go out onto the landing to let the visitor in.

How to connect an electromechanical lock to a video intercom?

If you want to protect your own territory from intruders, you should not limit yourself to ordinary deadbolts. An electromechanical lock on the gate, a video panel and many other complex devices will not surprise anyone, even more so - it is difficult to find a yard with a gate that does not have an electric lock and intercom.

How to choose an electromechanical lock?

Gates with an electromechanical lock, in fact, are not very different from a conventional mechanical lock. The design of such devices has an important feature, namely the presence of an electrical component that makes it possible to control the locking mechanism with a magnetic card, a key receiver, or a keyboard for typing a specific code. The door opens after the electronic device unlocks the lock.

Video intercom models with built-in recorder

This type of video intercom contains both an intercom and a video recorder. Thanks to additional functions, using such a device you can not only answer an incoming call, but also monitor the situation on a flight of stairs or in the surrounding area. You can also record video surveillance and save it to a memory card or to the cloud on the Internet. This additional feature is very useful in today's world. This way you can always see who scratched your neighbor’s car and even take a photo of the criminal and hand it over to law enforcement agencies.

Most often, video intercom models with DVRs can forward calls to a mobile phone and make it possible to view video in real time from both a phone and a computer or tablet. To do this, you need to connect the video intercom to your phone via the Internet through a special application.

So, photographs and names of intercoms known to us:

Wireless video intercom models

There are wireless models of video intercoms. Already from the name itself it is clear that the main advantage and difference from other monitors is the absence of wires in the design of the device. This video intercom is much easier to install yourself. There is no need to waste time on laying cables and the appearance of the room remains unchanged. You won’t have to glue wallpaper or tint the walls where the wires should have been.

Most often, wireless monitors are purchased for apartments where it is not possible to install a wired video intercom for technical reasons. In some cases, the installation of an apartment intercom and the installation of an entrance intercom are not carried out simultaneously. In order to solve the connection problem in the future, wireless models are purchased.

The disadvantages of wireless intercoms include sensitivity to bad weather. A thunderstorm, snowfall or rain can disrupt the signal quality or completely drown it out. Other external factors may also affect the passage.

The operating principle of wireless video intercoms is similar to the functioning of a radio channel. Communication between the monitor and the calling panel is carried out via radio frequency. For high-quality operation of the device, the distance between the panel and the monitor should not exceed 100m.

Many video intercoms now work over a Wi-Fi network. For this purpose, a special unit is installed in the monitor. Naturally, using such devices is a pleasure. And the connection is not difficult; you can do it yourself. However, such a system is expensive and not everyone can afford it.

What are the difficulties of connecting a video intercom?

The main difficulty with connection is that not all audio intercoms are compatible with video systems. Practice shows that today 90% of devices are compatible, but there is no guarantee that your home does not fall into the ill-fated 10%. You can find out about the possibility of connection by the marking plate, which is applied to the back of the device with the tube. Some other connection features:

• An electric door lock can be integrated with a video intercom system. But installation is not always easy - it is better to entrust this work to professionals.
• Chinese video intercoms are of low quality and often have unauthorized modifications made in Russia. Such devices are not subject to warranty service, so you should not buy them.

What to pay attention to when connecting

Other features of connecting a video intercom:

• Before installation work, be sure to study the operating diagram of the device. Installation must be carried out in accordance with the instructions, otherwise the operation of the system is not guaranteed.
• Pay special attention to the connection of wires. A four-core cable is usually used to connect the external and internal units - if the polarity is reversed, the system will not work.
• The adapter is often connected directly to the video intercom. But there are devices that operate from the mains or voltage panel (read the instructions for details).

Tantos

Tantos has long been a leader in sales of video intercoms in our country. A particularly popular model from this manufacturer is the Tantos Amelie apartment intercom. The 7-inch color monitor and touch screen allow you to use this device comfortably. In addition, additional functions are present:

• Possibility of connecting up to two calling panels.
• Two video cameras.
• Signal transmission in PAL format.
• Possibility to combine up to three monitors into an intercom system.

The monitor is sold complete with an installation bracket and mounting wires.

This model from Tantos has repeatedly confirmed its reliability and high quality workmanship.

Connecting an intercom to an entrance intercom with your own hands

Installing a video intercom is a simple task that you can do yourself according to the instructions above. If you have little experience, you can start working according to this scheme:

1. Buy the necessary devices and equipment, try to complete the installation yourself. There is nothing difficult about this - even a person without experience can make recesses and holes in the wall, and connecting the wires can be done according to the instructions.
2. If you suddenly make a mistake, it’s okay. Excess recesses and holes in the walls can be covered with plaster. If the wires cannot be connected correctly, they can always be re-soldered. If everything goes wrong, you can always call a specialist - he will finalize the installation and eliminate your mistakes.

Connecting a video intercom is simple, but as with any business, it has its own characteristics.

Cable for connecting an intercom.

When selecting a cable to connect the panel to the intercom, it is important to consider the length of the line. When using thin cables, the signal level decreases over long distances.

• Up to 15 meters, the calling panel can be connected with almost any cable. Computer twisted pair cable, KSPV 4×0.5 cable are suitable, and even SHVEV cable can be used, not to mention KVK cables which can be used up to 30 -40 meters.
• For distances up to 50 m, a KVK 2x0.75 cable is recommended.
• More than 50m, the manufacturer does not guarantee the operation of the video intercom. However, when using the RG-6 Cable and any 2x1.5 power cable, it was possible to achieve the operation of the intercom at 100 m. At a greater distance, it is not possible to achieve normal operation of the intercom.

When laying cable lines along the street or under plaster walls, I recommend laying a computer pair together with a combined cable (KVK). Its cost is low and in the future it can be useful for transmitting additional power, video signals or control signals.

The electric lock requires an additional power cable.

The table shows the colors of cables from various manufacturers. All manufacturers of calling panels and video intercoms have different colors for the connection wires. Therefore, when connecting, use the connection instructions and connect according to their functional meaning, and not color.

*The manufacturer reserves the right to change the color of the wires.

Falcon

High-quality Falcon equipment occupies one of the leading positions in the intercom systems market. Video intercoms of this brand have a wide range of models, as well as a wide variety of built-in functions.

Apartment monitors of this brand are equipped with a color screen and have a four-wire connection system. The signal format for these devices is standard PAL/NTSC. It is possible to control the lock using the calling panel. Many devices have the ability to customize the intercom. You can change the melody and customize the screen saver. In addition, the user will be able to shoot video and take photos during a call.

If you are looking for a high-quality video intercom for an apartment, then you should pay attention to the Falcon FE-Slim model. It is the thinnest monitor on the market. The thickness of the device is 9mm. The aluminum body and touch screen make the video intercom super stylish and able to decorate any hallway, while providing reliable security for your apartment.

Another popular model from this manufacturer is Falcon Eye FE-71 TM. The monitor has a 7-inch widescreen screen. The menu is entirely in Russian. Using this video intercom, you can record video from 4 cameras in color and watch the broadcast of video surveillance of the territory online. Additional functions of this device include a photo frame, alarm clock and answering machine. This way you can not only secure your apartment, but also get an additional multifunctional device for your home.

Areas of use of a comprehensive video surveillance system

The equipment is installed in apartment buildings, private properties, warehouses and enterprises.

The purpose of the video intercom

The main objectives of the device are to limit unwanted visitors, increase the safety and comfort of residents.

Features of the video intercom

During the call, the owners see the visitor’s image on the monitor and may not answer him or open the door remotely.

If you have an answering machine, you can listen to a recording of a message from a guest. The equipment saves video and photos of what is happening near the entrance to a memory card.

Using the built-in camera, you can view the staircase, exit to the street, and courtyard.

Difficulties and features of installation

It is difficult to connect a video intercom in an apartment building without experience. It is necessary not only to install the equipment, but also to lay the wires. The problem is connecting all the components according to a certain scheme. The failure of one device will disrupt the operation of the entire system.

Connecting equipment to a regular entrance intercom is difficult. First, they install a video panel, which most often does not combine with the audio system. Therefore, you will have to do the installation again and lay all the wires.

VIZIT

Manufacturers of security systems VIZIT are at the forefront of designing intercoms. The range of this company is distinguished by the simplicity of devices made with color and black and white screens. Video intercoms easily connect to almost all entrance intercoms. Therefore, you can buy a model for your apartment that will suit all your requirements.

Typically, the settings of VIZIT video intercoms are adjusted using buttons on the device body. The screen itself turns on when an incoming call arrives or when the handset is picked up. Typically, several CCTV cameras are connected to the monitor at the same time. But a distinctive feature of VIZIT monitors is the impossibility of simultaneously displaying images from all surveillance cameras on the screen at once. You can only watch videos by switching between cameras one by one.

All models of this brand are marked:

• S – video intercom with built-in power supply
• C – color image;
• M – there is video memory.

Otherwise, the operating principle of “Visits” is no different from the others. There is a light indication of all operating modes. This is especially convenient when simultaneous calls are received from different calling panels. The indication will help the user navigate and answer incoming calls correctly.

Also, some video intercoms of this brand can open electromagnetic locks using a separate DOOR button.

Handset design

The residential subscriber device consists of two parts. This is a handset and panel that is usually mounted on the wall next to the front door. The handset can be installed anywhere, you just need to lay the wire around the apartment. Inside the handset there is a microphone, a speaker and a small board with discrete elements. The panel has a handset release lever, and the handset itself has a door open button.

The electronic lock button can also be located on the wall panel. In modern models, the lever is replaced by a reed switch, and there is a small magnet on the tube itself. Some models may have a handset switch. On the back of the panel there are two screws marked “+” and “–”. A two-wire line is connected to them.

The wires should be connected to the intercom handset with correct polarity, otherwise the intercom system will not be able to be used - it will not work.

All access intercoms installed in the entrances of apartment buildings are divided into two groups:
• coordinate;
• digital.

Based on the types of intercoms, apartment handsets also have slight differences. In coordinate intercoms, a switch installed in the entrance is responsible for the apartment number, and in digital devices, a special chip, which is located on a board inside the handset.

CTV brand video intercoms

The CTV brand usually produces video intercoms with a color monitor and a calling panel with a built-in color CCTV camera.

CTV monitors most often have internal memory, which makes it possible to capture the screen. There is often a slot for a microSD memory card, which in turn makes it possible to store large amounts of media files.

Video intercoms of this brand allow you to connect up to four additional screens when creating an intercom network. You can also configure call forwarding to another video intercom.

Devices most often have power indicator lights and communication with several calling panels, a speaker and a microphone. There is also an on-screen menu in Russian, a volume control and other additional functions. For example, such as changing the melody, viewing photos and videos on the monitor screen, alarm mode, recording video when the alarm mode is turned on, as well as switching between cameras when shooting video. It should be noted that photo and video shooting mode is done manually.

Types of intercom code keys and the principle of their operation

All chips can be divided into contact and contactless. The first devices worked with simple keys that had two contacts. They have shown to be unreliable because they can be easily copied and the system loses security. The simplest keys quickly replaced chips that were capable of transmitting binary code. The number of possible combinations is determined by the number of binary bits transmitted.

Nowadays, more and more intercoms are equipped with contactless elements. The exchange of signals takes place over a radio channel. The blocks communicate at frequencies of several tens of kilohertz, and the radius does not exceed three to four centimeters.

The general principle of the key's operation can be represented as follows: a certain code is enclosed in an electronic chip, which is scanned upon contact with the reader on the call block. If the key code matches the code in the unit’s memory, the system sends a signal to “open the lock.” The electromagnet temporarily stops working and the door opens. If the codes do not match, the system will not respond.
