I was looking for a battery-powered camera for the back door that was impossible to use with a wired device. I found this solar outdoor camera from soliom . Setup is easy and I love the complete wire free feature. It can recharge itself through its solar panel. Powered this camera entirely on solar is such a huge benefit. Running entirely on solar, this camera will keep on recording even if your power is cut off. The cameras have a pretty good image quality...
