Determines the threat on time

MotionProtect Curtain — motion detector with a long distance range and narrow protective screen. Curtain detector effectively protects the property from intruders and works as soon as a burglar enters the protected area.

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.
MotionProtect Curtain will prevent intruders from entering in your backyard unnoticed. If the burglar tries to climb over the fence, the detector will raise the alarm. At the same time, your family and pets can move freely on site.

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.

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.

In Office

Indoors MotionProtect Curtain can be installed horizontally, upside down or at the angle. The sensor will monitor all access paths around the clock without reacting on people inside.

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.

Detects even the most cunning intruders

It doesn’t matter how fast the intruder moves, runs or walks slowly. As soon as he is in MotionProtect Curtain's field of view, the detector receives signals from two PIR sensors, compares them and immediately alerts of any attack.

Notifies of sabotage attempts

The anti-masking system ensures that MotionProtect Curtain is working properly during the day and at night. If the detector is blocked, painted, sprayed or taped, the device sends an alarm signal.
  • Anti-masking system is always active
  • Protected from tampering and dismantling attempts
