I have nearly all my cameras setup with RTSP. VLC is the easiest test to see if it is working. If you have the RTSP options in the Advanced settings then the firmware is correct. Not sure if you may have something on you network blocking RTSP, but it is a possibility. If you can reach the cameras with the Wyze app, they are on the network and the IP reported in the settings should match what you have on your router. Just tried to ping one of my cameras and it did respond.
Do you have your network segmented in some way? Different subnets? Firewall blocking? etc…
URL for VLC should be something like:
rtsp://user:password@192.168.1.4/live
