Reliable perimeter protection

At home

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.

In a garage

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.

At a museum

The visitors can stroll the exhibits as they please. But if they cross the line and reach towards an artwork, an alarm will be raised.

In a pet-friendly apartment

When installed correctly, MotionProtect Curtain keeps your private property safe and ignores the pets, even if they are Saint Bernards.    

Proprietary optical technology

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.

Rapid reaction to threats 

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. 

Reliable radio communication

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.

Set up in 2 minutes

MotionProtect Curtain connects to the security system via Ajax app: scan the QR code, add the detector to the room, and proceed to installation.
