The Voltolux infrared motion detector RS97B uses passive infrared technology, which detects temperature differences in the environment to be monitored and thus reliably detects both lateral and frontal movements in the detection area. The switch-on time (3 s to 30 min), the response brightness (5 - 2,000 lx) and the covering of individual detection segments enable precise light control. This model is made of high-quality polycarbonate and is very robust.
