Motion Sensor

Passive Infrared (PIR) motion sensors from Lorex can be used to add some simple video-free security to your house. They are designed to sense any moving heat signatures that pass in front of the sensor. Simply peel and stick to locations around your house, including ceilings, walls, or the top of any flat surface, to know the moment any movement is detected. Pair up to 10 Add-On Sensors to the Lorex Sensor Hub or up to 32 to the Lorex Smart Home Security Center.

Do I need a Starter Kit to Use Add-On Sensors?



If using standalone or with an NVR or DVR system.

Add-on Sensors connect to The Lorex Sensor Hub, which connects to the Lorex App.



If using with the Lorex Smart Home Security Center.

Add-on Sensors are connected directly to the Lorex Smart Home Security Center without a Lorex Sensor Hub.


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.

Sensor Linking with Wireless Cameras
