I have 2 solar security cameras. When adjusting the zone motion sensitivity, there used to be a display from the camera with the area being adjusted shaded in blue. As you adjusted the sensitivity up or down you could see the blue shaded area increase or decrease to indicate what area of coverage you would have.
It now seems the display is gone and you have to guess what area is being covered. Was this an intentional change or what? It was very helpful to actually see what area I was monitoring.
