My Motion Detection Area is grayed out in the NVR cameras. I have 8 camera wireless NVR package.
I also have a couple of extra camera (bought before the NVR package) that have the Motion Detection Area enabled.
I believe at one time this did work, but not luck for several months.
I’m trying via the Zmodo app and the actual NVR. However the NVR doesn’t have this choice, but only the masking. It might be the masking that is the answer, mask out what I don’t care to see move (ie Flags and such).
