Sandra Bullock seemed surprised to find her now ex-husband Jesse James had cheated on her. It wasn’t the first time, either. Some of James’ extra-marital activity took place in their home.

It’s a safe bet that theyhave some kind of security system; most celebrities do so to help control their privacy. Apparently Ms. Bullock had nothing to track what was going on in her home when she wasn’t there. Couples in love want to trust each other, but when one strays, trust doesn’t matter anymore.

There are many ways to catch someone without them knowing it. In addition to the security cameras we’ve all seen, there are hidden cameras that are disguised as something else.

Among them are air freshener, Exit sign, mirror, fan, boom box, CO detector, clock radio, smoke detector, electrical box, phone, desktop speakers, emergency light, baby monitor, clock, and more.

There is even a screw hidden camera.

If you have, or suspect you have, any reason to question the safety of your home, second home, or office, one or more hidden camera can be the tool you need to keep an eye on things when you can’t everywhere.
