Is it usual to have CCTV in the living room and then also to have it recording all the time even when you're in the house? I've been following a trial where a lot the evidence has come from footage the defendants recorded themselves on an internal CCTV camera. The camera seems to be on constantly day and night even when people are in the house. I understand people might have a security camera for when their out or to monitor pets but just to have running all the time especially when you're committing crimes Infront of it. Also I don't understand why they didn't just destroy the camera and footage.
