**Describe The Problem:**
I am running this plugin on my RasberryPi 4, have configured a local account which is in the admins group but no cameras appear in the HomeKit app. There are no errors in the logs either so I am really stumped.

I am certain that the username and password are correct and the Pi can reach my controller, there are no firewalls in between they are connected via an unmanaged switch. All other HomeBridge plugins are working. 

I was also sure to install FFmpeg with the following command:
`sudo curl -Lf# https://github.com/homebridge/ffmpeg-for-homebridge/releases/latest/download/ffmpeg-raspbian-armv6l.tar.gz | sudo tar xzf - -C / --no-same-owner
`

Am I missing a step to add the cameras to my HomeKit? Are there any verbose logs I can access?

**To Reproduce:**
- Install plugin
- Configure username/password
- Click Save
- Restart HomeBridge
- Wait for cameras to appear in HomeKit
- Cameras never appear
