We recommend using MotionProtect Plus sensors in areas such as lofts, garages with metal roofs, glass conservatories, and any other rooms that experience temperature fluctuations.

The sensor comes with a battery and is therefore ready for installation. Scan the QR code on the back of the device with your smartphone and it connects to the hub. It can be mounted to the wall on the SmartBracket in just a few minutes.


  • The Ajax MotionProtect sensor can operate up to 5 years without battery replacement.
  • The additional microwave sensor filters possible interference from an air conditioner or curtain movement.
  • It is “pet-friendly” and ignores pets weighing up to 20 kg and with a height up to 50 cm.

The Plus is designed for operation in rooms with fireplaces and air conditioners. It detects and ignores draughts, movement of curtains and blinds, light flickering, glare and reflections.

The Ajax MotionProtect Plus detects human presence by temperature difference with background thermal radiation. The microwave sensor prevents false alarms caused by complex interference.

Please note:

  1. Ajax alarm systems require a network connection
  2. For the system to work with your armed response company you will need to confirm they support Ajax. The system can work without armed response and send you alerts.
