Bosch ISM-BLP1 Motion Detector

The ISM-BLP1 detector uses a high-density (77 zone) Fresnel lens designed to produce sharply-focused images throughout the field of view to provide superior response to intruders. First Step Processing (FSP) almost instantly responds to human targets without producing false alarms from other sources. FSP adjusts the detector's sensitivity based on signal amplitude, polarity, slope, and timing. This eliminates the need for the installer to select the sensitivity level. The ISM-BLP1 also has an easy wiring access with plug-in terminals.
