1、The outdoor infrared detector uses signal analysis and processing technology to improve detection and anti‑false alarm performance. 2、Different detection holes improve the stability and different use environments, the rainproof, waterproof and dustproof design enables it to be used outdoors. 3、The sensor light can be switched on and off; will flash once when turned on and a person or vehicle passes by, and will not flash when turned off to last longer. 4、Anti‑disassembly design, automatically press the dustproof button after the battery is installed and fixed, to prevent the detector from being disassembled or destroyed maliciously. 5、Two detection distances, 0‑6 meters and 6‑12 meters can be adjusted freely, so that the sensing is more accurate and no false alarms.
