One of my screens has this tonight and i have no idea why. Never seen it before. Its only on one screen and its blinking.

Please help. Im trying to catch a stalker. He only comes to my property at night, on the night vision he appears much thinner on camera. Is there a way to fix this? Whats the best picture quality i need it set to in display mode? Why does the night vision made make you look thinner?
