Varifocal mirrors dramatically improve the focus and level of energy collected by the pyro sensor regardless of range. The electronic gain of the detector is reduced and therefore the Signal to Noise ratio is optimized to virtually eliminate false alarms. This design also provides an improved freedom from false alarms with its unprecedented level of immunity against visible light.
The ASIC signal processing implemented in the CRT series allows the detector to identify human movement with extreme accuracy, validate intrusions and program itself to cope with harsh environmental applications.
The CRT series offers an unparalleled detection capability and stability for every security installation. It includes various models adapted to each type of installation, from the smallest device for curtain pattern protection to the most sophisticated sensors.
