No surveillance job is too big for the world's smallest 2.4GHz color camera! This unbelievably tiny camera is no bigger than a postage stamp and has the power to transmit, real-time, full-color video to any TV or VCR within 300 feet. It can be powered by an AC adapter OR a portable battery pack, so you can place this camera virtually anywhere! Hide it in a houseplant or air conditioning vent to make sure your nanny isn't mistreating the kids while you're away. Mount it in a mailbox to see who's been swiping your mail. Or place it in the kitchen cabinet near the candy stash to make sure your kids aren't secretly raiding it — the applications are endless! Requires 4 AA batteries (sold separately). The camera transmits over the powerful 2.4GHz spectrum, making sure images arrive crystal clear -- even through walls and floors. Just set up the camera, connect the 2.4GHz receiver to the TV or VCR, and the system is up and running! The camera/transmitter comes with a receiver, two AC adapters (one for the camera, the other for the receiver), a battery pack and two RCA cables. The battery pack requires 4 AA batteries, which can power the camera for approximately 10 hours.
