How do you use the RTSP?

Welcome to the Forum, @roolies13! 
What Cam(s) are you actually using, and what are you trying to accomplish? You tagged your topic for Cam Pan v4 (which does not yet have RTSP-enabled firmware released) and Web View (which shouldn’t figure into the use of RTSP at all), so more detail from you is necessary in order to provide specific guidance.
For general instructions with compatible Cams, Wyze has provided a page describing the current state of testing, and discussion can be found in these topics:
None of that is currently applicable to Cam Pan v4, though.
Pan v3 and just want to be able to see my cameras from a desk top. I remember when Wyze first lunched, there was an app and it worked then it stop working and disappeared from App Store
There is beta firmware and available for the Panv3 with RTSP support. As far as the viewing software, you have your choice of quite a few 3rd party apps.
In that case, you can consult the first link in my previous post about the off-site page Wyze created for RTSP testing. As of last week, the RTSP firmware for Cam v3 and Cam Pan v3 has been released to the production channel (the fourth link in my reply above is to this announcement), but that’s a phased roll-out, so it may take a while before a given user sees the latest RTSP production firmware available for his or her Cams. If you’re interested in trying RTSP sooner, then your primary option is probably to get the older firmware from the off-site page and flash it to your Cam Pan v3. Note that you will need to be using Wyze app v3.8.5+ in order to take advantage of the features offered by these newer firmware versions.
