Security cams for the paranoid on a budget

Four wireless cameras for $275

Smarthome

We're not so paranoid that we need technologies that can tell who's spying on us, honest. All we want to do is conduct constant surveillance around our perimeter at all times, so we can dispatch the guard dogs as necessary. (Until we finish filling the moat, anyway.)

The problem, however, is that we're cheap--and surveillance equipment often isn't. But something like the "Mini-Air Watch4" system might just work. For a relatively reasonable $275, Gadgetizer says the system comes with four wireless color security cameras and a video receiver that can work from 100 to 300 feet away. And you can even switch back and forth among the feeds with a remote that's included so you can play security guard in a home control room. (Uniform and hat not included.)
