I recently picked up an inexpensive dual-lens Yoosee camera. It works well, but there’s a catch: it doesn’t provide separate video streams for each lens. Instead, it merges both lenses into a single frame, which makes viewing difficult even though the camera can technically be added to a Hikvision DVR.
After some research, I found a way to split the combined frame into two separate streams and feed them individually into the DVR. Here’s the approach I used:
You’ll need a Linux machine on your network. In my setup, I have an old Xeon system running Proxmox for various home-lab tasks. Through Proxmox, I installed Go2RTC, which handles the stream splitting.

bash -c "$(curl -fsSL https://raw.githubusercontent.com/community-scripts/ProxmoxVE/main/ct/go2rtc.sh)"After installation, open the Go2RTC interface by visiting:
http://IP:1984You need the stream URL for the camera you want to split. You can easily change the camera password through its app. If you’re unsure how to retrieve the ONVIF/RTSP URL, look it up first as it varies by model. For my Yoosee camera, the ONVIF URL looks like this:
onvif://admin:[email protected]:5000Once you’re on the Go2RTC configuration page, paste in the necessary config to split the stream.
rtsp:
listen: ":8554"
users:
admin: pw123
streams:
cam1:
- onvif://admin:[email protected]:5000
camA:
- ffmpeg:cam2#raw=-vf crop=1920:1080:0:0#video=h264#media=video
camB:
- ffmpeg:cam2#raw=-vf crop=1920:1080:0:1080#video=h264#media=video
If everything is set up correctly, Go2RTC will now split and restream your camera feed via port 8554. You can then go to your Hikvision DVR interface, add a custom camera protocol, and point it to the new stream.
After that, add the camera.
That’s fine — it works very well. However, I noticed that after the camera has been running for a long time, the stream occasionally freezes for no apparent reason. I’m not sure what causes it, but I did find a workaround: simply restart go2RTC every 10 minutes.
To do this, I created a scheduled task on my VM and added a script named restart_go2rtc.sh.
