I know you weren't asking this but....I just bought the Marcum PanCam camera and it is super easy to use. It sends a Wi-Fi signal to your phone , tablet, ipad, or even laptop so they turn into the viewing screen. You can pan 360 degrees just by touching whatever device you are using. I would recommend checking them out. We used the camera for at least 5 hours the one day and it still had just over 50% life on the battery.
