Bosch Security Systems of Fairport, New York, has launched a new generation of Blue Line Motion Detectors. Blue Line Gen2 provides improved catch performance, enhanced false alarm immunity, and easier installation. Available in standard and pet-friendly models, the new series is suitable for residential and commercial applications. Models include passive infrared (PIR), Quad PIR, and TriTech units that combine PIR and microwave technologies. All devices use an interchangeable mounting base and cover a 40- by 40-foot wall-to-wall area. Detectors analyze motion to differentiate human targets from other sources of movement and automatically adjust sensitivity based on signal amplitude, polarity, slope, and timing.
