DT92

DT92 is a dual technology detector (MW + IR) suitable for wide areas thanks to the 25m operating range.

The MW section is provided with an high sensitivity DRO planar antenna and with a sophisticated device wich allows to detect the masking. In the IR section there is a double anti-masking device which allows to detect the blinding from an opaque or reflective body.

A key point of this detector is the use of a digital PIR to obtain a very high immunity against noises and accurate detection.
