DoorProtect Plus


A wireless magnetic detector alerts the user to the first indications of a room invasion through a door or window.
Authentication to prevent forgery
Jamming detection and communication channels encryption
Tampering alarm
Up to 5 years of battery life
Detects changes in inclination angle, shocks and vibrations
External contact is available for connecting third-party detectors

Operational principles

Using high-end reed switches built in Britain that are affected by the magnetic field, the device can detect when a door or window is being opened. It has a transmitter mode that enables it to communicate with the hub by sending a signal from the connected sensor.

Features

Even windows left open for ventilation are protected by the device. An alarm is sent to the hub when the accelerometer detects changes in the vertical slope angle, bangs, or vibrations.

Installation and set up

Ready to use right away: There is no need to disassemble the detector because the battery is already in place. It can be linked to the hub on the mobile application with just one click. It takes only a few minutes to mount it on the SmartBracket.
