I use a Wyze PTZ inside the camper, that way I can turn it and see what our dog is up to. It works great the only issue is its Chinese .. For outside I have a Reolink camera and it to works great, I chose reolink for outside because it uses a small solar panel to power the camera. I mounted the panel on the roof and the camera by the door. Works great, never have to do anything with it. For the inside I also use a govee temp/humidity wifi thermometer. It will send me a notification if the temp gets above a preset temp so I know that my dog isn't suffering from a loss of cooling or heating. I currently use a ToGo dome for all my wifi needs. It works great and I haven't been anywhere yet that I haven't received a signal. What I also like is that I can setup the rv's wifi and then change the source of internet connection between 4g, park wifi with my phone. This way if the park has good wifi I don't use my data. Also all of my devices are logged into the rv's wifi, so I don't have to log them back in every time I change my internet source.
