Do your black enclosures cover up the red light on the front of your cameras? I have mine turned off, but having them turned on is always an option. I also have assorted outside housings for mine, but can’t remember at the moment if my black housings have that display covered up or not.
I am in a 2 story house, but opting to NOT put holes in my siding or eves has limited my “out of ball-bat” options and only one is on the second story. I have enough cameras to overlap both front and back approaches, and if “Thuggy” can’t see them in the daylight, he’s higher than corn in Iowa. At night, I’d rather not advertise.
Statistically, your B&E is going to be from someone who has previously been to your house before, familiar with your family or someone from a nearby neighborhood. So they know you have cameras already.
