Features: 1.Unique intelligent detection technology, wireless 433MHZ alarm transmission to avoid pet interference. 2.Large detection range, 110 wide detection angle , maximum coverage area 12 *12m. 3.Fresnel optical lens effectively prevents false positives and false negatives. 4.Lower window technology effectively overcomes the traditional detectors shortcoming of no alarm for crawling intrusion. 5.Super anti-white light 6500lux enables to alarm even under the interference of white light. Specification: This device mainly used indoors adopts infrared detection + intelligent volume recognition technology to effectively prevent pet interference and false positives. It is principally paired to use 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._x000D_ _x000D_ Features:_x000D_ _x000D_ Unique intelligent detection technology, wireless 433MHZ alarm transmission to avoid pet interference. _x000D_ Large detection range, 110 wide detection angle , maximum coverage area 12 *12m. _x000D_ Fresnel optical lens effectively prevents false positives and false negatives. _x000D_ Lower window technology effectively overcomes the traditional detectors shortcoming of no alarm for crawling intrusion. _x000D_ Super anti-white light 6500lux enables to alarm even under the interference of white light. _x000D_ Dual infrared + intelligent volume recognition + mirror type + artificial intelligence quadruple technologies, dual lens, dual temperature compensation technology. _x000D_ Intelligent recognition technology, low standby current, 2 universal AA batteries can sustain long service life for more than 2 years without changing batteries. _x000D_ Wall-mounted installation and special plug-in installation design, flexible to use and easy to install. _x000D_ _x000D_ Specification:_x000D_ Condition: Brand New_x000D_ Material: ABS_x000D_ Detection Distance: 12m_x000D_ Detection Angle: 110_x000D_ Maximum Coverage Area: 12m * 12m_x000D_ Anti-white Light Intensity: 10000Lux_x000D_ Pet Immune: 25KG_x000D_ Transmission Distance: 150m (open space)_x000D_ Working Voltage: 3V (2 AA alkaline batteries) (not included)_x000D_ Standby Current: 8A_x000D_ Alarm Current: 15mA_x000D_ Wireless Frequency: 433MHZ (1527)_x000D_ Alarm Indicator: Long bright for 3 seconds_x000D_ Working Environment: Indoor, outdoor_x000D_ Tamper Switch: Normally closed_x000D_ Alarm Output: Alarm report, tamper report_x000D_ Installation Method: Wall hanging (adjustable direction)_x000D_ Size: Approx.105*55*45mm/4.1*2.2*1.8in_x000D_ _x000D_ Package List:_x000D_ 1 * Detector_x000D_ 1 * Mounting Bracket_x000D_ 1 * Screw Bag_x000D_ 1 * User Manual
