433MHZ Wireless Infrared Detector Alarm 110° PIR Sensor 25KG Pet Immune Security Alarm This device mainly used indoors adopts infrared detection + intelligent volume recognition technology to effectively prevent pet interference and false positives. It is principally paired e with the alarm host via wireless 433MHZ signal. When the device detects an intruder, it immediately transmits the wireless 433MHZ signal to the alarm host so that the host immediately transmits alarm information after receiving the immediate transmission. Features: Unique intelligent detection technology, wireless 433MHZ alarm transmission to avoid pet interference. Large detection range, 110° wide detection angle , maximum coverage area 12 *12m. Fresnel optical lens effectively prevents false positives and false negatives. Lower window technology effectively overcomes the traditional detectors shortcoming of no alarm for crawling intrusion. Super anti-white light 6500lux enables to alarm even under the interference of white light. Dual infrared + intelligent volume recognition + mirror type + artificial intelligence quadruple technologies, dual lens, dual temperature compensation technology. Intelligent recognition technology, low standby current, 2 universal AA batteries can sustain long service life for more than 2 years without changing batteries. Wall-mounted installation and special plug-in installation design, flexible e and easy to install.
