With the camera mounted inside the garage, with views of the garage doors, will the camera’s motion detection system detect metal garage doors opening and/or closing?
Seems like it would since the motion detection uses changes in pixels and not PIR.
Yes, I have one in this configuration currently and it works very well.
If you have windows in the garage doors, you will also get some motion detected when the lighting changes.
I also would not enable sound detection on that camera. Mine used to send notifications all the time when it got windy outside.
