Analog video devices are used in the multi-apartment sector. The devices are equipped with a standard set of assemblies and do not have options for upgrading. They are used in the driveway scheme, one switch serves up to 80 subscribers.

Digital intercom models with video are easy to install, connected using four wires, and do not require time-consuming preventive maintenance and maintenance. Self-diagnosis and display of information about an error in operation on the screen are provided. Malfunctions are stopped by a special device that does not allow one breakdown to disrupt the operation of the installation.

IP video devices use a Wi-Fi network to transmit information over a distance. Video intercoms of this type are expensive, but they are multifunctional control systems with automated access coordination.


Wireless video intercom

Devices are installed in places where cable laying is undesirable, intercom models use a radio channel to transmit information. The wireless path allows the outdoor panel to communicate with the receiving handset at a distance of 100 meters.

Compact models are manufactured in the form of a tube with a camera and an internal communication device. The model is a portable device that fits easily into a pocket.

  • portable;
  • built-in.

The information is stored on the SD card, which can be changed to increase capacity. Multichannel video devices automatically transmit pictures to the screen from several surveillance cameras, record sound, transmit the image to the user on the phone.
