Ever suspect that someone is poking into your stuff when you're not at home? Or that instead of taking care of the kids the babysitter is doing you-know-what? Or that Spot only pretends she can't stand on her hind legs and talk when you're around? Then you might want invest in one of the new spybots on the market. (That, or get your head checked.)
Would you like to reduce the size of your home security system? Like something on the order of magnitude of motion detectors that can fit on a postage stamp? These tiny rectangular sensors are actually powerful passive infrared (PIR) detectors that can be easily slipped into an area where their larger PIR brethren couldn't even dream of fitting.
