These steps modify the G2H camera to enable RTSP, telnet, lock a few things down and not to call home. See wiki for mode info.
Clone this repo to the root of an SD card.
Insert the card, power on the camera.
login via telnet --> telnet G2H_IPADDRESS (user: root, pass: password)
The camera will reboot when it's done and remove the SD card. Use at your own risk.
