MotionProtect Curtain Jeweller
Narrow beam indoor motion detector. Protects windows, doors, and valuables
Key features
Detects motion with a range of up to 15 meters
Works up to 3 years on the pre-installed battery
Transmits alarms at a distance of up to 1,700 meters away from the hub
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.
Unique wireless technology
Jeweller is Ajax’s proprietary radio protocol for secure two-way communication. It provides block encryption and device authentication during each communication session with an Ajax hub or radio signal range extender. Jeweller prevents sabotage, spoofing, and data theft.
- Up to 1700 m of communication range in an open space
- Data encryption
- Notification of jamming and connection loss
- Automatic power adjustment
2-minute set-up
MotionProtect Curtain connects to the security system via Ajax app: scan the QR code, add the detector to the room, and proceed to installation.
