Here are some pictures that you requested. As you can see in the first picture, when the room’s overhead lights are turned on, the Night Vision IR turns on (turning everything black & white); however, when the overhead lights are turned off and the room is relatively dark, the Night Vision IR is not on (2nd picture).
The following shot is from this afternoon (camera happens to be pointed in a different direction, but the problem is the same - and please ignore the dishes on the counter,haha). Full daylight in the room with the overhead lights on, but the Night Vision IR appears to be on, making everything b&w.
And here is a screenshot of my Night Vision IR settings. It has always been set this way (for 2 years). But like I said before, the Night Vision seems to have been operating in the opposite behavior than it should for the last month (apprx. since the time that camera’s firmware was updated).
Could it be that the Night Vision sensor went bad? Any help you can give would be appreciated.
