The Ajax MotionProtect Plus is an indoor motion detector designed to integrate seamlessly with all Ajax hubs, range extenders, and bridges. To ensure high reliability and minimize false alarms, it combines a PIR sensor with a 24 GHz microwave sensor, meaning both must trigger for an alarm to be sent. This dual-technology approach allows the device to detect movement up to 12 meters away within a horizontal angle of 88.5° and a vertical angle of 80°, delivering the alarm signal in just 0.15 seconds. Its black housing measures 110 × 65 × 50 mm and weighs 96 g, making it discreet when mounted at the recommended height of 2.4 meters. The detector is built to be pet-friendly, ignoring animals up to 50 cm in height and 20 kg in weight. You can adjust the sensitivity across three levels to better suit your specific room layout and environment. Powered by a CR123A battery, the device can operate for up to 5 years without a replacement. It uses the Jeweller wireless protocol to maintain a connection over distances up to 1,200 meters in open spaces, utilizing block encryption with a dynamic key for security. An integrated temperature sensor monitors the room's climate, while the LED indicator provides quick visual feedback on its status.
