Ademco 5897-35 Wireless Dual Tec Motion Sensor

let me introduce our new wired pers and dual tech motion sensors range we designed the is 3000 and DT 8,000 motion sensors to offer easy and fast installation suiting the requirements of most applications our custom-designed mirror based optics provides superior accuracy at lower energy thresholds delivering better detection and fewer false alarms the optics and electronics are assembled in the front cover and sealed with a protective cover to prevent damage during installation our true sustained complaint anti masking technology provides superior protection against would-be intruders attempting to block the field of view with sprays and liquids it's an excellent solution for banks jewelry stores museums and other high-risk commercial environments normally a PIR sensor triggers an alarm when the signals exceed the sensor threshold however in case of weak signals for example low speed or
