People put a lot of trust in cameras as a deterrent. The thing is, the more cameras you have, the better it is... For a bad guy.
The cameras above were supposedly monitoring the entrace to a large data center. There were supposed to be people looking at the feed all the time... But, people being people... Well, they weren't.
We danced in front of the cameras for a few minutes and nothing happened. So, we took our time working the lock for the data center. A few minutes later we were inside, removing ethernet cables from random servers and causing some IT manager to be awaken in the middie of the night.
