@Peter b,
Here is a list of things to address today::
1) Is the camera a CGO3 with no 360 degree panning, or the CGO3+ that can pan 360 degrees.
2) If it is the CGO3, it needs to be tried out on your Q500 with the ST-10+ (or ST-12) controller
3) if it is the CGO3+, it needs to be tried out on your Typhoon H with the ST-16 controller
4) When it is mounted on the drone and powered up you should be able to see the SSID (networking name) of the camera on the 5.8GHz WiFi on your phone or computer. A CGO3 will be CGO3_XXXXXX and a CGO3+ will be CGO3P_XXXXXX, where the X's are the last 6 digits of the camera's MAC address label on the side of the camera.

Note that the endcap on the camera should denote CGO3 or CGO3+ and the MAC address is on the label.
Below is where my phone was connected to my CGO3+, note the last six digits matching the label’s last six digits.
Let us know what you get.
