How to broadcast video from CCTV cameras to your web page?

Question

CCTV

Good afternoon. The facility has ozero DVRs. It is necessary to display these cameras online mode in the html page. They have rtsp protocol, but the provider does not give an external access port. cameras work through p2p. are there any alternative solutions?

Answer 1

In case of not giving an external address, I use rtsp redirection through my vpn server.
As an option - we rent a vps server (example hatzner, $ 3 a month.) We connect vpn there, we take a picture from it.
p2p most likely will not work, usually it is only used for the "cloud" of the manufacturer
