Steps to reproduce the behavior:

1. Running Balena v2.61.3 on Raspberry Pi 4 - Camera is Longrunner Raspi Pi4 Model B+ Camera module with switching.
   Installed using Balena etcher
2. On Balena I've set BALENA_HOST_CONFIG_start_x = 1 plus also set GPU Memory settings as suggested in other posts.
3. On the Raspi command line i can see the camera is now working :

vcgencmd get_camera
supported=1 detected=1

3. In Kerberos.io System is running and ive set the config as follows.
   

Here is the content of my config. (this has not been edited)

So got this working by selecting IP camera. Not sure why this is specific to Pi4 , Pi3 RPI camera works.

hey @djmgrant sorry for the late reply, you made it working by enabling IP Camera setting?

[djmgrant]

Yes thats correct. Quite weird really. My friend bought the exact same camera and on raspberry pi 3 his camera worked as an Rpi camera. Not a big deal but took me quite a while to work this out, swapping ribbons and power sources etc etc.
