This mini dvr spy camcorder is the smallest digital video camera in the world! Smaller than a BIC lighter, and just about as cheap! It is very fashionable, wearable and matches all kinds of portable tools making it the perfect little spy cam unit. This camera records 720X480 video in AVI format at 30 frames per second.
You can set the camera up in a room on audio-activated standby mode, where it will happily sit for nearly two weeks on a single battery charge until a noise activates it. It uses microSD, which means you can store up to 8GB of footage on it and it plugs into your computer via USB (which also charges it) to let you transfer files.
