Video is a great thief repellant. It is one layer of security that must be incorporated into every home security system. However there is no such thing as 100% security. And while video often catches a thief in the act, it can’t actually catch a thief. That’s what police are for.
In Des Moines Iowa, which I’ve been to a few times and is a very cool place, lots of Bald Eagles, a bar owner was awoken to a phone call from ADT Security calling to tell him the alarm in his bar was going off. At the same time the police were summoned.
Meanwhile the bar owner logged into his security systems internet enabled cameras and saw the legs of a man dangling from the ceiling through ceiling tiles! The criminal apparently cut a hole in the roof! Then he saw the man jump to the floor with a crowbar and immediately head towards his target: a ticket machine full of cash.
Obviously the thief knew what he was after. After about 3 minutes he ran out when the police arrived and narrowly escaped.
Now the police have video footage of the thief to use to hopefully catch him.
Security is about layers of protection. The protection in this case at least minimized the damage by sending off a piercing alarm reducing the damage the criminal would do if he stayed longer and then the cameras will help identify the thief. Fortunately the bar owner has insurance (which is another layer of protection) that will ultimately pay for the loss and damage.
