  • 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
  • When installed correctly, MotionProtect Curtain keeps your private property safe and ignores the pets, even if they are Saint Bernards
  • To create MotionProtect Curtain, we’ve developed an optical system of two infrared sensors and a multifaceted mirror. This system allows the detector to receive twice as much information about what is going on in the protected area and instantly react to human presence
  • 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
  • MotionProtect Curtain connects to the hub through radio communication at a distance of up to 1,700 meters. Jeweller, the proprietary two-way communication protocol protects data transmissions with advanced encryption. In case of interference or jamming, Ajax security system switches the frequency and alerts you and your dedicated alarm response company.
