Changing camera type

In Cosmostreamer system terminology, a camera is any device that Cosmostreamer can work with. DJI Pocket, DJI Osmo, Goggles - this all a "camera".
MicroSD image with Cosmostreamer configured for "DJI Goggles2/Integra" by default, so need to change a "camera type" for using with DJI Goggles V1/V2.

1. Open device settings in CosmoViewerNG application or in web interface
2. Go to chapter "Info"
3. Choose camera type "DJI Pocket 3"
4. Don't forget to click "Save" button.

License key

License key is a text string, unique for each Raspberry Pi. Each camera type needs different license keys. It's possible to install multiple amount of license keys on one device and use this device for some camera types, i.e. Pocket Osmo, Pocket 2, and others. Need to buy license for correct operation process.

1. Buy license key on a product page
2. Make a photo of HDMI display or screenshot of the app with a QR image and send it in email on cosmostreamer@gmail.com for making a license key
3. When you got a license key - use web interface or CosmoViewerNG application, menu "device settings" -> "License" and insert license key into field. And click "Install license" button.
