This is a simple Virtual Onvif Server that was originally developed to work around limitations in the third party support of Unifi Protect. It takes an existing RTSP Stream and builds a virtual Onvif device for it, so the stream can be consumed by Onvif compatible clients.
Currently only Onvif Profile S (Live Streaming) is implemented with limited functionality.
Unifi Protect 5.0 introduced support for third party cameras that allow the user to add Onvif compatible cameras to their Unifi Protect system.
At the time of writing this, version 5.0.34 of Unifi Protect unfortunately has some limitations and does only support cameras with a single high- and low quality stream. Unfortunately video recorders that output multiple cameras (e.g. Hikvision / Dahua XVR) or cameras with multiple internal cameras are not properly supported.
Run this tool on a Raspberry Pi or similar to split up a multi-channel Onvif device into multiple virtual Onvif devices that work well with Unifi Protect 5.0.
Ensure you are running Rapsberry OS 11 (Bullseye) or newer and have Node.js v16 or higher installed.
To check your version of Node.js run this command:
node -vTo install Node.js run these commands:
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.5/install.sh | bash
# Open a new Terminal / SSH connection
nvm install --ltsTo install all required dependencies run:
cd /path/to/onvif-server/
npm installTo properly work with Unifi Protect each virtual Onvif device needs to have its own unique MAC address. The easiest way to achieve this is by creating virtual network interfaces with the MacVLAN1 network driver:
ip link add [NAME] link [INTERFACE] address [MAC_ADDRESS] type macvlan mode bridgeTip
It is recommended to reserve fixed IP addresses in your DHCP server for your virtual networks.
Replace [NAME] with a name of your choosing (e.g. onvif-proxy-1) and [MAC_ADDRESS] with a locally administered MAC address2 (e.g. a2:a2:a2:a2:a2:a1) and [INTERFACE] with the name of the parent network interface (e.g. eth0).
# Setup the first virtual network with name "onvif-proxy-1" and MAC address "a2:a2:a2:a2:a2:a1":
sudo ip link add onvif-proxy-1 link eth0 address a2:a2:a2:a2:a2:a1 type macvlan mode bridge
# Setup the first virtual network with name "onvif-proxy-2" and MAC address "a2:a2:a2:a2:a2:a2":
sudo ip link add onvif-proxy-2 link eth0 address a2:a2:a2:a2:a2:a2 type macvlan mode bridge
# Setup the first virtual network with name "onvif-proxy-3" and MAC address "a2:a2:a2:a2:a2:a3":
sudo ip link add onvif-proxy-3 link eth0 address a2:a2:a2:a2:a2:a3 type macvlan mode bridge
# Setup the first virtual network with name "onvif-proxy-4" and MAC address "a2:a2:a2:a2:a2:a4":
sudo ip link add onvif-proxy-4 link eth0 address a2:a2:a2:a2:a2:a4 type macvlan mode bridgeImportant
All virtual network settings will be lost when you reboot the server and will need to be redone!
The configuration can be automatically created by running:
node main.js --create-configEnter the hostname and credentials of your real Onvif Camera server and copy/paste the generated configuration into a new file config.yaml and change the <ONVIF PROXY MAC ADDRESS HERE> fields to one of your virtual network MAC addresses each.
onvif:
- mac: a2:a2:a2:a2:a2:a1
ports:
server: 8081
rtsp: 8554
snapshot: 8580

bitrate: 160
quality: 1
target:
hostname: 192.168.1.152
ports:
rtsp: 554
snapshot: 80The above configuration creates a virtual Onvif device that listens on port 8081 of the a2:a2:a2:a2:a2:a1 virtual network and forwards the RTSP video streams and snapshots from 192.168.1.152 (the real Onvif server).
Finally, to start the virtual Onvif devices run:
node main.js ./config.yamlYour Virtual Onvif Devices should now automatically show up for adoption in Unifi Protect as "Onvif Cardinal" device. The username and password are the same as on the real Onvif device.
A prebuilt docker image can be found in the packages section of this repository.
All you need to do is to mount your config.yaml to /onvif.yaml inside the container.
Example of running the image in a temporary container:
docker run --rm -it -v /path/to/my/config.yaml:/onvif.yaml ghcr.io/daniela-hase/onvif-server:latestTo create the configuration from inside the docker container you can change the entrypoint of the container to /bin/sh:
docker run --rm -it --entrypoint /bin/sh ghcr.io/daniela-hase/onvif-server:latest
# Once inside the container, run:
node main.js --create-configThis tool can also be used to create Onvif devices from regular RTSP streams by creating the configuration manually.
RTSP Example: Assume you have this RTSP stream:
rtsp://192.168.1.32:554/cam/stream
\__________/ \_/\_________/
| Port |
Hostname |
PathIf your RTSP url does not have a port it uses the default port 554.
Your RTSP url may contain a username and password - those should not be included in the config file. Instead you will have to enter them in the software that you plan on consuming this Onvif camera in, for example during adoption in Unifi Protect.
Next you need to figure out the resolution and framerate for the stream. If you don't know them, you can use VLC to open the RTSP stream and check the Media Information (Window -> Media Information) for the "Video Resolution" and "Frame rate" on the "Codec Details" page, and the "Stream bitrate" on the "Statistics" page. The bitrate will fluctuate quite a bit most likely, so just pick a number that is close to it (e.g. 1024, 2048, 4096 ..).
Let's assume the resolution is 1920x1080 with 30 fps and a bitrate of 1024 kb/s, then the config.yaml for that stream would look as follows:
onvif:
- mac: a2:a2:a2:a2:a2:a1 # The MAC address for the server to run on
ports:
server: 8081 # The port for the server to run on
rtsp: 8554 # The port for the stream passthrough, leave this at 8554
name: MyRTSPStream # A user define name
uuid: 1714a629-ebe5-4bb8-a430-c18ffd8fa5f6 # A randomly chosen UUID (see below)
highQuality:
rtsp: /cam/stream # The RTSP Path
width: 1920 # The Video Width
height: 1080 # The Video Height
framerate: 30 # The Video Framerate/FPS
bitrate: 1024 # The Video Bitrate in kb/s
quality: 4 # Quality, leave this as 4 for the high quality stream.
lowQuality:
rtsp: /cam/stream # The RTSP Path
width: 1920 # The Video Width
height: 1080 # The Video Height
framerate: 30 # The Video Framerate/FPS
bitrate: 1024 # The Video Bitrate in kb/s
quality: 1 # Quality, leave this as 1 for the low quality stream.
target:
hostname: 192.168.1.32 # The Hostname of the RTSP stream
ports:
rtsp: 554 # The Port of the RTSP streamYou can either randomly change a few numbers of the UUID, or use a UUIDv4 generator3.
If you have a separate low-quality RTSP stream available, fill in the information for the lowQuality section above. Otherwise just copy the highQualtiy settings.
Note
Since we don't provide a snapshot url you will onyl see the Onvif logo in certain places in Unifi Protect where it does not show the livestream.
- All cameras show the same video stream in Unifi Protect
Unifi Protect identifies cameras by their MAC address - if multiple cameras have the same MAC address they will be treated as the same. It is possible your system is configured for all virtual network interfaces to report the same MAC address, to prevent this run these commands4:
sudo sysctl -w net.ipv4.conf.all.arp_ignore=1
sudo sysctl -w net.ipv4.conf.all.arp_announce=2- Error: Wsse authorized time check failed.
Try updating the date/time on your Onvif device to the current time.
- I only see snapshots, no live-stream.
Are you capturing the RTSP streams of your cameras elsewhere already? It is possible that you hit the maximum concurrent RTSP streams that your camera supports.
Unifi Protect also seems to only support h264 video streams at the moment. So ensure your real Onvif camera encodes videos with h264.
