Not that I know of. I only have one of my cameras shared, and that’s with a friend of mine who also has a couple Wyze cameras and we wanted to test out the sharing functionality. No indication as far as I could tell that the camera was being watched by someone else - other than seeing there there was more traffic from that camera on my WiFi. With a little effort, I could fairly easily determine the IP of the phone that was watching from my router. Note that I am not using consumer type routers nor WiFi and I can see a lot more detailed information that most consumer devices can.
