Ajax Wireless Curtain Detector

Ajax Wireless Curtain Detector

  • With the MotionProtect Curtain detectors, you can secure the perimeter of your house and freely move indoors. If a stranger breaks in, the system will raise an alarm and call the security company.


    Burglars won't get through the garage door undetected when MotionProtect Curtain is in action. The curtain detector will continue to operate even if the temperature drops to -10°C.


    Whether the intruder is running or sneaking — MotionProtect Curtain is always on duty. As soon as they enter its field of view, the detector analyzes signals from both PIR sensors and immediately sends an alert.
