Feature:1. The outdoor infrared detector uses signal analysis and processing technology to improve detection and antifalse 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. Antidisassembly 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, 06 meters and 612 meters can be adjusted freely, so that the sensing is more accurate and no false alarms.Specification:Item Type: Infrared Driveway AlarmMaterial: ABSUse: OutdoorBattery: 2pcs AA battery, 1.5V (NOt included)Quiescent Current: 25uAAlarm Current: 25mADetection Interval: 5 SecondsDetection Distance: 1st level approx. 0-6m/0-20ft, 2nd level approx. 6-12m/20-40ftDetection Angle: 90 DegreesOutdoor Use: Rainproof (IPV44)Installation Height: Approx. 1-2m/3.3-6.6ft (detection vehicle), 2-4m/6.6-13ft (detection of human body)Transmission Frequency: 433MHZTransmission Distance: Approx. 300m/984ft in the openWorking Temperature: -10 to 50.Package List:1 x Infrared Driveway Alarm 4 x Screw1 x Detector Port Replacement1 x Manual 1 x Bracket1 x Base
