CVD-123 Security Sensor


CVD-123 infrared security sensor is applied to detects changes in infrared range caused by intruders moving through the detection pattern.

Consists of separate transmitter and receiver.

CVD-123 - Digital twin beams detector incorporated in plastic case. Enables lens alignment angle at ±10° (vertical) and ±90° (horizontal). Internal heating ensures flawless operation in temperatures from -40 to +50°C.

CVD-123 outputs an alarm when the infrared pulse beam emitted from its transmitter is not received by the receiver for a certain period of time.

CVD-123 can be mounted on a pole and on fencing.

CVD-123 consists of:

- transmitter – 1 pc.;

- receiver – 1 pc.

- mounting kit – 1 set

Receiver and transmitter are placed facing each other at the opposite sides if protected area. Transmitter emits IR beams heading receiver. Movement within the detection zone between receiver and transmitter triggers alarm. Receiver transmits alarm to controller by means of wired communication. Controller then forwards information to data collection and processing system.


CVD-123 can operate independently or as a part of perimeter security systems.
