The camera setup we use relies on ONVIF for discovery, which is handled by two bits of software. rpcd-mod-onvif on the receiving device to carry out WS-Discoveries and various ONVIF control functions, and camera-mod-onvif on the camera device side to respond. Here’s a bit of an informal diagram:

There are a few reasons this might fail:

- either rpcd-mod-onvif is sending ONVIF out the wrong interface;
- camera-onvif-server isn’t listening on the correct interface;
- /dev/video0 on the camera device has not come up - which camera are you using? You may need an additional driver

On the camera side, what is the output of `logread | grep camera-onvif-server`.  
On the viewing side, what interface is it configured for in the WebUI?

Yes, but let’s try some debugging first 🙂

You can plug the dongle into a Raspberry Pi. The steps as followed in [Build Thread: HaLow for Raspberry Pi OS](https://community.morsemicro.com/t/build-thread-halow-for-raspberry-pi-os/1124) will be largely the same, except for USB you won’t need to worry about device tree.
