A famous painting was swapped with a cheap forgery during a blackout. The gallery owner swore the security cameras would prove his innocence, as they had battery backups. When Detective Cole reviewed the footage, he saw complete darkness during the hour of the theft. Why did Cole arrest the owner anyway?
Security cameras use infrared or night-vision lenses
Even during a power outage, security cameras with battery backups and infrared capability would have recorded images, but the footage was entirely black because someone intentionally covered the camera lenses.
