Bosch TriTech Long Range Motion Detector

The TriTech long range motion detector by Bosch Security Systems of Fairport, N.Y., combines passive infrared (PIR) with adjustable microwave sensing technologies. The narrow field of view detector features a 100 X 10 foot coverage area, the company says.

The detector also comes with the company's sensor data fusion (SDF) technology that helps reduce false alarm rates by enabling intelligent simultaneous processing of signals from up to eight sensors.
