Reviews Passive Infrared Intrusion Detector

4VWIN driveway alarm provides a convenient and economic way to alert you the moment when someone is approaching your home

  • LONG RANGE CONNECTION - Motion Sensors can connect with Receivier from up to 350 feet away(in open space)!.
  • PASSIVE DETECTION - Passive Infared (PIR) Technology continuously monitors for motion up to 25 feet away from sensor for any intrusion.
  • ADJUSTABLE ALARM - Choose between high or low volume alerts and flash the LED warning lights. Privately be aware when sensors have notice guests arriving to your property or raise the volume to warn trespassers to go away.
  • AVOID FALSE ALARM - Do not place the detector in areas where the wind will active it, also try to keep the detective in a clear path to the receiver, so that you can get optimal performance..
  • LONG LASTING POWER - Alarm Base: 3x Size 'C' 1.5V Battery or 6V DC Power Adapter (Not Included).
  • Motion Sensor: 1x 9V Battery Each (Not Included)（For the best performance, please use fresh,high-quality, Alkaline batteries.）.
