Window / Door Sensor

Take your security beyond video monitoring with a Window / Door Sensor Set from Lorex. Small, but incredibly crucial, this sensor will notify you the moment a window or door has been opened. Simply stick the sensors on any door or window frame in your home. Then, the moment that their close connection is broken you will be notified through the Lorex App. Connect a total of 10 sensors to the Lorex Sensor Hub or up to 32 to the Lorex Smart Home Security Center to ensure you always know of any windows or door openings.

Link Sensors to Lorex Security Cameras

Automatically start the recording on a compatible Lorex security camera the moment an add-on sensor is activated. This means that the linked camera will already be recording before it is able to detect the motion itself, which can give you valuable pre-event video to provide more context.
