Peepholes are all very well, but you actually have to leave your chair to find out who's calling, and that's never good. Thankfully, there's now a more high-tech option for the sedentary (or peephole-lacking) among us.

The Secure Sight records all your visitors, whether you're in or out, so you can see who's calling right now as well as who came by when you were at the market. (Better than TV!) You fit the camera to your door and put the viewer wherever is convenient.

Personally, I'd also put a sign up to let people know they're on candid camera, so you don't get any pesky accusations of eroding civil liberties... and also I'd consider upgrading to 4GB with an SD card.
