The white Ajax MotionProtect Curtain sensor creates an invisible curtain, protecting doors, windows, and specific zones, and detects attempts to intrude into the protected area. It notices an intruder up to 15 meters away as soon as they appear in the sensor's detection field. The device simultaneously uses two PIR sensors, allowing it to successfully detect both slow, creeping movement and fast running. MotionProtect Curtain maintains radio communication with the hub at a distance of up to 1700 meters. The two-way Jeweller protocol protects transmitted data with encryption. In case of interference or an attempt to jam, the security system switches to a free radio frequency, notifying you and the security company. The sensor is easy to install and configure without special knowledge: mounting on SmartBracket fasteners is convenient and won't damage repairs, and connection to the central unit is done via a mobile application with just one click. The device is ready to use out of the box, with the battery pre-installed.
