Ajax MotionProtect PlusProtect Plus motion sensor with optional sensor

Principle of operation

It detects the appearance of a person in a protected room at a distance of 12 meters from the sensor according to the temperature difference with the background thermal radiation. Ignores the movement of inanimate objects and pets weighing up to 20 kg and growing up to 50 cm.


An additional microwave sensor eliminates false alarms of the sensor from composite interference: drafts, shivers of blinds, movement of curtains, reflections and light in rooms with air conditioning or a fireplace.

Installation and setup

The sensor is ready to work out of the box. There is no need to disassemble the case - the battery is already installed. Adding a device to the Ajax Hub is done by scanning a QR code in a smartphone application. The SmartBracket mount allows you to easily install the sensor in a few minutes.


  • Detects movement at a distance of 12 m. 
  • Radiofrequency scanning filters out the noise caused by thermal radiation in combination with the movement of the curtains, trembling blinds and strong reflections. 
  • SmartDetect algorithm - the sensor recognizes and does not respond to movements of pets up to 50 cm tall and weighing up to 20 kg.
  • Housing protected against tampering or tampering
  • Battery life up to 5 years
