“its probably fine and not haunted haha…” (I’m stuck living here for the next three months because of unavailable low rent housing)
Or it may be brighter in infrared lighting due to an old spill, so the area the camera focuses to appears to be an area that’s more reflective and thus closer to the camera (like a person standing in front of the background)
Most cameras use reflectivity for autofocus rather than time-of-flight, tof is mostly only commonly used in higher end smartphones, despite what manufacturers tell you.
