This is a  copy of post on my Face Book Page take a look a the Video Link, The guy did a good job on it.  "Stories sometimes breathe a breath of reality into our lives; I heard a person telling a story about how somebody came into his yard and took several pieces of equipment. Another person said that he knew of another incident just like that, and then he said that is why he has cameras at his business.
Cameras don’t stop a crime, but if they are installed where they can cover areas where somebody may approach a building or office, they could allow you to possibly get a picture of the perpetrator, or maybe even deter them from continuing to be a bother.
To Catch the Office Thief – The office is empty and nobody is around, my desk and domain are safe, then why is my apple gone!"

Depending on your business, the cost of installing surveillance equipment may not be that great, and it could help you answer questions when things go wrong.
