Battery Powered
Battery powered hidden cameras are devices that are powered by internal rechargeable batteries, making them ideal for short-term and portable surveillance situations. The great thing about battery powered nanny cams is that they can be placed exactly where you need them - on a desk, shelf, in a vehicle, a garage - all without having to worry about a power cord, which can make some devices hard to hide. Depending on the camera, battery powered spy cameras can get a few hours to several months of battery life at a time, so be sure to check the specs for the different devices to help find one that is suitable for your particular video needs.
