Have you seen: https://github.com/keshavdv/unifi-cam-proxy ? I'm using it to integrate a 3rd party camera with a UDM pro to be able to record the footage. Homebridge-unifi-protect picks it up and displays the still in Home, but trying to play the video it doesn't work. I get a no response

**Describe the solution you'd like:**
<!-- A clear and concise description of what you want to happen. -->
I understand that this is not the purview of homebridge-unifi, but it would be nice if it were supported if possible so I can integrate the 3rd party camera into Home without having to install another plugin and exclude this camera from the plugin.  

**Describe alternatives you've considered:**
<!-- A clear and concise description of any alternative solutions or features you've considered. -->
Add homebridge-ffmpeg or camera and install the 3rd party camera there and exclude it from homebridge-unifi-protect
