Is here any agency to determine if here are clandestine cameras surrounded by a room? Maybe something can be bought at Frys.?
Answers: Electronic video equipment uses something called oscillators surrounded by order to work. Oscillators are also exactly what make radio tranmissions work. So, in a minute road, video cameras do radiate a little dash and can be detected. For consumer grade cameras, the expense of shielding them is freshly too much. Cameras installed in some command installations are much better shielded and cost a LOT. Obviously, you're not worried about those.
Stores that get rid of video surveillance equipment to companies like video rental stores will also own available "pens" that can detect radio wave secretion, as well as more expensive "bug" detectors. (Eavesdropping "bugs" or buried microphones haven't gone the way of out-of-date spy movies. They gotten even smaller and more sophisticated and include button size camera pickups now.
The 'pens' aren't adjectives that great, but can pick up amateur spying attempts, and they're not terribly expensive. Look on a poke about engine for SPY SHOP and your area. Likely near is a store not far away that sells surveillance and detection equipment. It's a huge industry.
I don't know if this in actuality works, considering the source, probably not.
I got a catalog within the mail from a place call "Things You Never Knew Existed" and they had a pen to be precise supposed to be able to detect undetected cameras.
