Manufacturer overview
Narrow beam indoor motion detector. Protects windows, doors, and valuables
Reliable perimeter protection. 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.
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.
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.
Ajax product categories. In an Ajax system, you can combine devices of all product categories: Intrusion protection, Video surveillance, Fire and life safety, or Comfort and automation. Create the system to suit your needs and manage it in a single interface.
