The dual-technology detectors associates a passive infrared (PIR) sensor with a high-frequency microwave sensor with Doppler effect. The passive infrared detector detects temperature variations in its detection field during an intrusion.

As for tThe Doppler detector uses a microwave transmitter and receiver antenna that , it is all about a high-frequency transmission and reception antenna which transmits a pulse and analyses the signal reflected by the environment. The frequency differences between the signal transmitted and the signal received provide information about the moving objects in the detection area.

Technology points:

• – Cost-effective solution
• – Easy installation on any material
