Do you have trouble in choosing a reliable detector? This First Alert Security Wireless Digital Motion Detection Sensor will be your wise decision! The digital temperature compensation for better accuracy under fluctuating temperatures can effectively reduce the false alarm rate of the detector. In addition￡? the wireless digital PIR detector is designed to be mounted on surface or corner￡? which provides further flexibility in aiming the detector. The detector also comes with digital temperature compensation￡? digital microwave detection￡? patented digital auto pulse signal processing and digital shield TM algorithm software. It will keep your home security while allowing pets to move freely anywhere in the house. It&acute;s the best protector for your house or office.
