Tiny spy cameras are great and everything, but generally speaking you end up sacrificing quality for size. Tiny cameras just can't compete with the big boys. Or at least most of them can't — this Iconix HD camera is the size of an egg yet can still shoot in high-def.
A mere 2-inch cube weighing in at 2.5 ounces, the tiny video camera can shoot in a number of formats, frame rates, and resolutions, making it more than just a gimmicky toy. You can also rig up to six of the cameras together, giving you a complete, HD view of your neighbor's bathroom. Just make sure to hide them properly.
