The Ajax MotionProtect is a wireless indoor motion detector designed to secure your living space by identifying movement using a PIR sensor. It monitors an area up to 12 meters away with a horizontal detection angle of 88.5° and a vertical angle of 80°, ensuring comprehensive coverage when installed at the recommended height of 2.4 to 2.5 meters. To prevent false alarms, the device features a Smart Detect algorithm and pet immunity, meaning it ignores animals up to 20 kg in weight and 50 cm in height. This compact white device, measuring 110 × 65 × 50 mm and weighing only 86 g, integrates a temperature sensor to monitor your indoor climate within a range of -10°C to +40°C. You can adjust the sensitivity across three levels to suit your specific environment, while the system ensures rapid response with an alarm delivery time of just 0.15 seconds. It is powered by a single CR123A battery, which can last up to 7 years, and includes adaptive transmission power control to maintain a stable connection with Ajax hubs, range extenders, or bridges. Designed for easy installation, the kit comes with a mounting plate and all necessary hardware. The detector is protected against tampering and uses digital temperature compensation to maintain accuracy even as the room temperature changes, making it a reliable choice for homeowners who want a discreet yet effective security layer.
