Tunnel RTSP camera to Intenet

As example, you have camera:

rtsp://admin:password@192.168.1.123:554/cam/realmonitor?channel=1&subtype=0

Run Ngrok on any computer in you LAN (use your token):

ngrok tcp 192.168.1.123:554 --authtoken eW91IHNoYWxsIG5vdCBwYXNzCnlvdSBzaGFsbCBub3QgcGFzcw

You will get similar output:

tcp://0.tcp.eu.ngrok.io:11465 -> 192.168.1.123:554

Now you have working stream:

rtsp://admin:password@0.tcp.eu.ngrok.io:11465/cam/realmonitor?channel=1&subtype=0
