The Ajax MotionProtect is a wireless indoor motion detector designed to integrate seamlessly into a security system. It utilizes a PIR sensor to monitor a space, detecting movement within a range of up to 12 meters with a horizontal angle of 88.5° and a vertical angle of 80°. To ensure accuracy, the device features the Smart Detect algorithm and digital temperature compensation, which help distinguish actual threats from environmental noise. You can adjust the sensitivity across three levels to suit your specific room layout, and the system delivers alarm signals in just 0.15 seconds. Measuring 110 × 65 × 50 mm and weighing 86 g, the detector is compact and available in white or black. It is designed to be installed at a height of 2.4 to 2.5 meters, allowing it to ignore pets weighing up to 20 kg and measuring up to 50 cm in height. The unit is powered by a single CR123A battery, which can last between 5 and 7 years depending on usage. For connectivity, it communicates with Ajax hubs, range extenders, and bridges over distances up to 2000 meters in a clear line of sight. Beyond motion sensing, this device includes a built-in temperature sensor that operates between -10°C and +40°C. It is equipped with tamper protection to alert you if someone attempts to remove or open the device. The package comes ready for installation with a mounting plate and a full installation kit, making it a practical choice for homeowners who want reliable indoor monitoring without the need for complex wiring.
