Dear RHDecks
I've manage to solve this issue and sucesfully integrate an Amcrest camera to my OBS, and this reference should work for any model accoring to their API SDK (Google this document, all info is in there)
Simple steps to follow:
1. Make your camera available via Amcrest app to grant it is actually working and all connections are Ok
2. Use the protocol as shown in the image, in the "BrowserSource" input space available in OBS (my personal configuration:
rtsp://admin:Camaras123@192.168.1.13:554/cam/realmonitor?channel=1&subtype=0&unicast=true&proto=Onvif)
3. You are ready to go!
Be aware of the video/audio sync, I estimate that there is a delay of 1 to 2 seconds from live video to OBS capture depending on the network configuration.
That being said, Amcrest cameras is a great option to have some feeds
