When I unbox a new Reolink camera, the first thing I do is open my Contacts file and add the camera information. One line for each camera, including the model number, UID code, and the IP address that I assigned to it. (OCD - every camera has a designated IP address on my WiFi network.) I have added cameras to my Reolink app from 3,000 miles away when I left my tablet in an UBER and had to buy another one.
