Although advertised as wireless, they are not. You need AC power. So if you're using them outdoors, this can pose a problem. However, they are good cameras for indoor use. They take really good pictures and are relatively easy to set up. They should. The supplied booklet says nothing about the use. I put in 64GB sticks to save the recording. They can only be set to record the movement of a person or object over 2 feet in height.
