We had an older system with contacts on the windows. Now with the Rogers system, we have 2 glass break detectors that cover most of our windows. We have 2 rooms that we keep the doors shut, so we installed door switches on them. We have only had the system for a week, but love it.
I do have one question if someone can help. We "tested" our system to see how the motion detector was set up (on delay as we wanted, but neither my husband or I remember asking the tech to do that) and now when we look on our security zones, it shows that all sensors are closed, but motion is detected under the motion detector section. How do we fix it?
I believe @andersonlms is speaking of Night Vision.
Which is built in to the camera's via InfraRed (IR) LED. When it gets dark enough, the camera has a built in sensor that automatically turns on the Infra-Red sensor to give it Night Vision.
Hope this helps.
