"I have a Dahua camera (model DH-SD2A500HB-GN-A-PV-0400-S2), but it doesn't have the privacy mask feature, which I really need. Is there another way to block certain parts of the view that the camera sees? Can a custom overlay be used to add a picture or something similar to cover some parts of the view? If not, could custom firmware help, or do I need to buy a new camera?"
