How video intercom works

The simplest video intercom consists of two components:

  • call panel with microphone, speaker and camera. It is installed at the entrance to the object;
  • monitor with microphone and speaker - located indoors.

The main function is the same as that of a conventional intercom:

  • by pressing a button on the call panel, the receiving module emits a signal and activates audio / video communication;
  • having recognized the visitor, the user remotely opens the lock on the front door by pressing a button.

Thanks to the presence of a camera, there is an additional function: at the command of the user or a signal from a motion sensor or a timer, photo and video can be taken. The most expensive models are able to send footage to e-mail.

The main elements of the video intercom are the monitor and the door station, all other components are installed when the electric lock control function is implemented

The camera also works in the dark, for this there is an infrared illumination on the call panel. The call panel is made in anti-vandal design, lenses made of safety glass are used in the camera.

Varieties of video intercoms

Video intercoms differ in purpose and design.


On this basis, video intercoms are divided into two groups.

For apartment

Video intercoms for an apartment have the following distinctive features:

  • the call panel is designed for operation in an unheated room;
  • it is possible to connect to the entrance doorphone through the interface unit.

The call panel is installed in front of the entrance door of an apartment or a vestibule uniting several apartments.

Most models are equipped with an interface for connecting additional cameras (up to 4 pcs.). They allow you to view the space in front of the entrance from a different angle (in addition to the camera on the call panel), monitor the area in front of the elevator, etc.

The apartment video intercom can be connected to the driveway via an external or built-in interface unit

For apartment intercoms, the function of communication with the concierge is in demand - the device is connected to the control panel of the entrance guard.

For a private house

These models are characterized by the following:

  • the ability to connect two outdoor panels to one monitor, while one is installed on the gate, the second on the front door of the house;
  • the call panel is designed for outdoor use - it can operate at temperatures from -40 to +50 o С.

Design features

Video doorphones also differ in completeness, functionality and technical characteristics.


By the way of organizing audio communication, video intercom monitors are divided into two types:

  • with a tube (like landline telephones);
  • with speakerphone (speakerphone).

Systems with a speakerphone are called Hands Free. The advantage of this solution is its compactness and a more modern look.

Video intercom equipped with speakerphone takes up less space

In some models the communication button has to be held down during the whole conversation, in others it is required only a short press, after the conversation the connection will be disconnected automatically.

Tube devices are larger but offer two advantages:

  • the sound is heard through the receiver more clearly and legibly;
  • a quiet speaker will not wake up a sleeping baby.

    The sound in the handset is heard clearly and legibly

Models are available with a radio tube equipped with a small display. This option is preferable for rooms with a large area.

Display diagonal

Varies from 9 cm (3.5 inches) to 25.4 cm (10 inches). The most popular devices are 17.9 cm (7 inches). Larger displays are chosen in two cases:

  • several cameras are connected to the video intercom;
  • the user is visually impaired.

Ability to transfer color images

In the early stages of video intercom production, technology did not allow for the transmission of color images with the same high quality as black and white. The situation has changed by now - now the only advantage of monochromatic systems is lower cost.

Internet access

Models with Internet access are called IP video door phones. The cost of such devices is relatively high, but the owner has the opportunity to receive captured photos and videos by e-mail and open the door to visitors while away from home.

Monitor execution

There are two options available:

  • wall;
  • desktop.

The former are more common. But if there is a cabinet with a shelf or a drawer unit next to the desired place for installing the monitor, the second option is preferable: you do not have to drill the walls for installation.


These include:

  1. Memory card. Allows you to save photos and videos for later viewing by the owner. The function is convenient for those who are away from home for a long time. Mostly microSD cards are used.

    Many models of video intercoms have a slot for installing a memory card, on which you can record photo and video images of visitors

  2. Motion Sensor. Activates the video camera when moving objects appear in its field of view. The footage is saved to the memory card.
  3. Call panel display. Models with this option allow two-way video communication.

Wireless video intercoms

In wireless systems, communication between the door station and the controller is carried out using radio frequency signals. The most expensive models are capable of transmitting data via Wi-Fi. The maximum distance between the call panel and the controller is 100 m.

The indoor unit is often portable. It is made in one of two versions:

  • in the form of a tablet;
  • in the form of a radiotelephone tube.

Despite the significant advantage of simplicity and low cost of installation, wireless video intercoms are used only as a last resort, when there is no possibility to lay a cable line. The reason is depending on the quality of communication on weather conditions and the availability between the call panel and the building controller.

Popular brands

The most widely represented are video door phones from several manufacturers.

Installation of video intercom

It is most correct to entrust the installation of a video intercom to a specialized organization. This solution has several advantages:

  • high quality of installation;
  • there is no risk of damage to equipment;
  • guarantee for the work performed.

But many are stopped by the relatively high cost of this service: it is commensurate with the cost of the device itself. Thus, self-installation allows you to save from 3 to 5 thousand rubles.

Required tools and materials

To work you need the following tools:

  • hammer drill or drill with percussion mechanism;
  • grinder or shtroborez (for a house made of foam concrete);
  • screwdrivers - flat and cross;
  • nippers;
  • crimping pliers for installing cable lugs (crimper).

Materials required:

  • dowels;
  • insulating tape;
  • connecting wires (four-core for connecting the monitor to the calling panel and electric type ШВВП 2х0.75 for power supply and electric lock line).

Work order

The main stages of installation:

  1. At the entrance to the side of the door at a height of 150–160 cm from the floor, a call panel is mounted. Sometimes for this you have to cut an opening in the door. The slots of screws or screws after installation are reamed to prevent intruders from removing the outdoor panel.

    In some cases, for the installation of the outdoor panel in the door leaf, you have to cut an opening

  2. A lock is installed on the doors. It may not be necessary to mount it, but in this case, the user will have to open the door with his own hands every time he calls.
  3. A cable line is laid from the call panel and the lock to the installation site of the controller, leaving a margin of 20 cm on each side. Two methods of laying are used indoors: open and hidden. In the first case, the wires are placed in a plastic box, screwed to the wall with dowels. This method requires minimal labor, but spoils the interior of the room. In the second case, a channel is cut out in the walls - a strobe. A corrugated pipe is laid here, into it - the video intercom wires (cable 4x0.22). After installation and verification, the strobe is filled with a solution.

    You can bring the necessary cables to the video intercom in boxes matched to the color of the room finish

  4. Indoors, at a height of 150–160 cm from the floor, the monitor is attached to the wall with dowels. The location is usually chosen next to the door, the power cord is plugged into the outlet, if there is one nearby, or routed to the electrical panel.
  5. The elements of the system are switched. For this, the supplied connectors are attached to the ends of the wires. After their installation, the bare sections of the wires are insulated with electrical tape.

  6. Plug the power supply into an outlet.
  7. Perform tuning and testing.

For models with hands-free (h ands free), the minimum cable length between the call panel and the controller is 1.5 m: at a shorter distance, the audio signal transmission is accompanied by interference

Repair and replacement of video intercom

During the operation of the video intercom, the following malfunctions are possible:

  • the image has become blurry, indistinct;
  • the image jumps or is transmitted with interference;
  • the sound is quiet or unintelligible;
  • the equipment has shut down.

Tools for repair:

  • multimeter;
  • phase indicator;
  • soldering iron;
  • pliers;
  • flat and Phillips screwdrivers.

Let's consider some of the most common faults.

Equipment shuts down spontaneously


  1. The phase indicator checks the presence of power supply in the socket.
  2. Check every connection. If necessary, tighten the terminals or clamps on the connectors with pliers.
  3. Measure the voltage at the contacts of the video intercom. Normally it is 12 V. Significant deviations can cause device failure. If they are found, check the voltage in the network. If it is normal (220 ± 10% V), the video intercom must be taken to the service center.

Image quality has deteriorated


  1. Cleans dust and dirt from the lens of the camcorder. First you need to vacuum the call panel, then wipe the camera peephole with a damp cloth. Along the way, cleaning with a vacuum cleaner will improve the performance of the microphone.
  2. If the situation has not changed, this indicates the development of its resource by the camera. It needs to be replaced. If the camera is built-in, the entire call panel changes. Just first, you need to make sure that the picture problems are not caused by a malfunctioning monitor or connection cable. To check, you must contact the service department.

Hearability in the conversation tube has worsened or the sound has completely disappeared

The most common cause is a disconnected speaker or microphone connector. To resume working, it is enough to solder the contacts with tin solder.

It is necessary to check the quality of the speaker connection and re-solder the wires if the contact is poor

Another reason is a broken wiring. The damaged wire is replaced.

Video: video intercom repair - broken wires

The call signal does not work

The reason is that the power supply contact of the speaker coil has come off. The connection is also restored by soldering.

Electric lock does not work

This happens due to oxidation of the contacts. Disassemble the lock and clean the contacts to a metallic sheen.

The problem can also be caused by the following reasons:

  • the lock is not powered;
  • controller failure;
  • wires disconnected from the lock;
  • breakdown of the relay in the monitor.

In case of such malfunctions, contact the service department.

Recommendations for using the video intercom

The owner of the device should adhere to these rules:

  1. The camera lens is regularly cleaned with a soft cloth.
  2. If there are significant voltage drops in the power grid, it is advisable to power the video intercom through a stabilizer.
  3. In case of direct sunlight or precipitation on the call panel, it is protected by a visor.


Installing a video intercom allows you to bring your home to a new level of security. Today, such systems are manufactured in a wide variety, so anyone, even those who are financially constrained, can find a model that is affordable for themselves. The above tips will help you take into account all the nuances and correctly install the device.
