In my case this url worked with opencv and python

rtsp://admin:****@192.168.0.86:554

8000 is not the RTSP port

Like you, I initially thought the port was 8000 after checking the Ezviz mobile app

The images are from a pdf I found : https://svtclti.com/manuales/CCTV/CAMARAS/EZVIZ/C%C3%B3mo%20activar%20RTSP%20en%20Ezviz.pdf

Required configurations

1. Log in to your EZVIZ account, and tap the profile icon on the top left corner.
2. Tap Settings
3. Scroll down to find LAN Live View
4. Make sure your camera and phone are on the same LAN, then tap Start Scanning.
5. Enter the device verification code as the password (usually located on the white sticker of your camera) and the username is admin by default, and you will be able to view your camera.
6. While the camera is connected (mobile app), go to the settings

7. Local Service Settings
8. Enable the RTSP and accept the warning
