Does IPVM Have A Compare/Contrast Document Between Port-Forwarding, Port-Triggering And VPN

Hello John:

We address the various options like Port Fowarding vs. VLANs.  Does this help?

John, port triggering is not applicable / used in video surveillance.

As, for example, the Wikipedia Port triggering article explains:

Port triggering is unsuitable for servers behind a NAT router because it relies on the local computer to make an outgoing connection before it can receive incoming ones. [emphasis added]

By contrast, in video surveillance, the remote computer (e.g., one's mobile phone) makes the incoming connection / request to start viewing video.

It's a good question, though. I had to check around on various sites to see if anyone was doing it for video surveillance, but I found no evidence and structurally that makes sense given how remote video surveillance monitoring works.
