Got my DB1 Pro working! With a tip from here Ezviz Disables RTPS for its IP Cameras, Here is the fix! | IP Cam Talk. Basically, seems like you can use some HikVision app (Windows for me, though seems there is a mac version available) to configure the camera and re-enable RTSP.
- Download and install iVMS-4200 iVMS-4200 V3.11.1.6 & 4200 AC V1.11.0.5 - Software - Hikvision
- I had to create an account
- Add your camera - for me, it found my DB1 Pro on the network where the Ezviz Studio did not. Usual creds to get the LAN live viewing through Android worked to get me access
- You can then access the camera settings via ‘Remote Configuration’, go to Network → NAT. It all looked correct for me, but I have seen people saying that re-entering the same details fixed the problem. So I disabled ‘Enable UPnP’ and saved, re-typed in the RTSP port of 554 and saved, then re-enabled ‘Enable UPnP’ and saved
I could then setup the camera in HomeAssistant and can access the feed via VLC (rtsp://admin:[PASSWORD]@192.168.XXX.XXX:554/Streaming/Channels/101)
I’m definitely turning off auto-update!
