Open.HD currently detects whether it is an Air or Ground unit by looking for an CSI camera. If one is found, the system assumes the role of the Air unit. When you use an IP camera as the main camera, the system will not find a CSI connected camera and will assume the role of Ground unit.

To prevent this, place a file called air.txt on the boot partition of the SD Card you use in the Air SBC. This forces the Open.HD system into Air unit mode.

Inside openhd-settings-1.txt change these settings:

SecondaryCamera=No
IsCamera1Enabled=0

To

SecondaryCamera=IP
IsCamera1Enabled=1

Now enable the band switcher:

IsBandSwicherEnabled=1

And remove the comment before these lines:

#IPCameraHiRes="gst-launch-1.0 rtspsrc...
#IPCameraLowRes="gst-launch-1.0 rtspsrc...

to

IPCameraHiRes="gst-launch-1.0 rtspsrc...
IPCameraLowRes="gst-launch-1.0 rtspsrc...

The settings in those two lines will need to be modified to suit your specific IP Camera and are only provided as a starting point.
