The Ajax MotionProtect wireless motion sensor is designed to detect human movement in a secure room. The sensor has adjustable sensitivity and is able to ignore pets weighing up to 20 kg and growing up to 50 cm. The principle of the sensor is based on the determination of infrared (IR) radiation from a living creature. Every living creature, including humans, is a source of infrared radiation. As soon as the sensor detects such radiation, it analyzes the mass of a living object, and if it exceeds 20 kg, sends an alarm signal to the central security alarm unit via a radio channel. A special algorithm for processing the incoming signal provides an additional verification of the object regarding the mass and the presence of movement, which minimizes false positives from moving pets. Thus, the sensor is triggered only when detecting human movement. Also, the sensor does not respond to the movement of inanimate objects. If in the room, for example, a jacket falls off the hanger, or a draft opens the interior door, the sensor will not work.

The sensor is equipped with an effective wireless radio communication system that uses message encryption and protection against forgery. This provides excellent security for alarms from hacking attempts. In addition, the sensor has an ultramodern highly reliable communication system that allows it to operate successfully within several floors of the business center or at a distance of up to 2000 m in an open area from the central alarm unit.

Ajax MotionProtect can be used to protect any objects: apartments, private houses, cottages, offices, shops, warehouses, industrial premises and more. The advantage of this sensor is its convenient and extremely easy independent installation using smart mounts; for installation, the user does not need to disassemble the sensor itself. A motion sensor is one of the most common elements of burglar alarms.


Easy to install and configure without special knowledge

Mounting the sensor using smart mounts is convenient and will not damage the repair
