These are good cameras. My only gripe is the battery life isnt great if in an area where they detect all the time. Mind you. Im getting 8 weeks or more and never been flat. But the bigger models give up to a yr. This brand is easy to use with the app. The distance is good for wifi connection. Im getting over 10 mtrs in line of sight. A really good, security system for not much momey and no wires.
