Branches / video surveillance / LAN - how to raise the network?

Question

VPN

I have a task to raise a network of video recorders. Without you, it will be difficult for me ... THIS IS WHAT I HAVE: There are video recorders, they are in different cities, different providers, different models, and there is no “static”. But I really need to moderate and watch them. As practice has shown, such devices work most stably with a static IP, clouds, NO-IP, DynDNS, and every hat will be a headache, and I don’t want to go there at all ... Ordering statics from providers is a very difficult task, especially if all this solve more than 40 times, forward ports, break what is already working there (POS, machines, access control systems) ... it will be very difficult. My idea is as follows… I get myself one external static address and write it as a gateway at all ends (registrators), I “nail” my own local address to each registrar (not in the provider’s range). Thus, I make my isolated LAN based on what I have. Question: Network guru - please answer, will such a scheme work? Or I don’t fully understand what a provider can do with such a network ... I know that there is a Site-to-Site VPN server,
but I still don't quite understand where exactly to look... Bless you!

Answer 1

For video surveillance, there are a bunch of solutions in the cloud. Try it you might like it. Your circuit will work too. But you need to consider the width of the channel. Perhaps your server will simply suffocate. In the general case, by the way, it is customary to put the video in a separate grid, or vlan.

Answer 2

IMHO, lift VPN, register routes and watch.
And of course, move cctv to a separate vlan, so the flow is quite large.
in a substream, it will not be so scary, but then the main one then eats a lot, a 2mp camera eats calmly from 2mb to 8.

Answer 3

It will even work in one direction, but you will not be able to route reverse traffic in this way.
