Tim Bohr, surveillance director of the MGM Grand at Foxwoods Casino in Mashantucket, Conn., manages a surveillance system that includes more than 4,000 video cameras and covers more than 340,000 square feet of gaming space.

Covering 4.7 million square feet with 340,000 square feet dedicated to gaming space, the MGM Grand at Foxwoods Casino located in Mashantucket, Conn., is one of the largest gaming facilities in the world.

One of the people in charge of keeping operations at the resort running smoothly is Foxwoods Surveillance Director Tim Bohr, who monitors the actions of the thousands of guests and staff who move throughout the facility on a daily basis.

Bohr worked in physical security and investigations within the banking industry before joining Foxwoods 13 years ago. Now he is charged with overseeing a massive surveillance network which includes more than 4,000 cameras.

In this "At the Frontline" interview, Bohr discusses how emerging video technologies have changed gaming security and how it helps him and others in the industry keep tabs on those who attempt to defraud casinos.

How many different areas of the casino and gaming stations are being monitored by your CCTV system at a given time?

We monitor any areas that have money handling areas, anything with table games, slots, cages, count rooms. All gaming-related activities are monitored by surveillance. I have three different surveillance monitoring rooms throughout the complex. We basically have five casinos under one roof.

What are some of your primary challenges in monitoring a casino of that size?
