"An inventor says he has come up with a better way to keep tabs on children, homes and other property: a wireless security camera that can go months without a change of batteries.
Similar security cameras either need to be plugged into a power outlet or run continuously on batteries that last less than a day. The Mailbox Cam -- at $199.95, more expensive than many security cameras -- extends the life of its three AA batteries by letting users control the device remotely, turning it off and on at will. A built-in timer also ensures that the camera is not accidentally left on for extended periods."
