Just a suggestion for maybe a rare reason.
It’s great to have a detection zone but the funny thing is I would find it more useful to set a non-detection zone. I have the camera on my porch and carport and whenever a car or person goes by the sensor sends an alert. If I could set a portion of the screen to non-detection that wouldn’t happen. No matter how I position the detection zone I end up eliminating an area I want to monitor.
