I have a motion sensor set up next to my front door (outside) and a v2 Cam behind the window on the other side of the door. Both the camera and motion sensor point at the same entryway area outside - this was a way to get around the IR vs glass issue and have the camera record when the motion sensor trips.
This worked great until it started raining a couple days ago. The sensor is somewhat shielded by a gutter and overhang but not well. Also coinciding was my installation of generic motion sensing light bulbs in the walkway nearby.
Now the motion sensor trips all the time - once every ten minutes all day and all night. During rain and dry periods. I have reviewed a LOT of boring video.
Any other data points on whether this behavior follows rain intrusion into the motion sensor, or if it’s more likely to be interference from other PIR sensors like my light bulbs?
