Ajax Door Protect - White
The DoorProtect is a wireless door sensor that notifies the owner of a door opening.
The device consists of two modules — detector and magnet. The set includes two magnets: the big magnet is installed at a distance of up to 2 cm, and the small magnet up to 1 cm.
The DoorProtect comes ready to operate straight out of the box: the battery is already installed, therefore there is no need to disassemble the detector. With one click, it can be connected to the hub in the mobile application and can be mounted on the SmartBracket in just a few moments.
