Several years ago there was a major bust of a museum thief. He had been stealing from museums all across the west and mid-west for 30 years. He stated in interviews that he would not steal from a museum that had obvious security cameras and monitoring. That is how he made it so long. He was caught by someone who noticed him walking out of a unsecured back door with a museum item. Probably his first mistake.
Security experts will tell you do not hide your surveillance, put it right out front so visitors see that you are watching.
