1. Mapping
Take C10Pro as an example, the camera is powered and connected to the receiver’s network port, open the gimbal FPV to see the mapping screen;
If you use a third-party camera, the camera network segment needs to be set to the 144 network segment (192.168.144.XXX), open the Device Tool – video viewing –click the setup button below – video stream address – customize, and enter the RTSP streaming address of the camera.
Note: Third party camera RTSP address need to ask the manufacturer for it.
If FLY GCS is used, then in the Common Settings – Other Settings – User Interface – Video Window – C10
Way 1: Open Settings -> Network and Internet -> Hot-spot and Network Sharing -> WLAN Hotspot -> Turn on ‘Use WLAN Hot-spot’.
Connect to the hot-spot of the remote control through your computer, and then start the VLC player on your computer. Select ‘Open Network Streaming’ in the media menu, and then enter the stream address of the camera, as in Figure 1, so that you can achieve the picture sharing.
Way 2: Open Settings -> Network and Internet -> Hot-spot and Network Sharing -> Turn on ‘Ethernet Sharing’.
Connect your computer to the TYPE-C port of the remote control via a network cable, and then start the VLC player on your computer. Select ‘Open Network Streaming’ in the media menu, and then enter the camera’s stream address, as shown in Figure 1, to achieve the picture sharing. (Requires C port to network port)
Figure 1
Note: The camera stream IP must be set to 192.168.144.XXX (XXX is an arbitrary number) and the gateway needs to be set to 192.168.144.11 to share the image transfer.
2.Data Transmission
