Connecting cameras to NVR at different locations

[normel]

I want to do the following, but dont know how to manage . So i need some help please. I will try to explain the situation.

There are 4 locations, lets say A, B , C and D

All of those locations have 2 ip camera's installed ( 2432 cube )

So now there is anoter location E, which is the office. The 8 channel nvr is located there. So i want to add all those camera's to the nvr, All locations have fast internet connections, but i can also survive with Second stream. Whats the most stable way? Thanks in advance. Hope someone can help

How far away are the sites?

What speed connection do they have? and download limits?

Are the sites networks linked up by VPN's or site to site links provided by an ISP ?

You could always just forward ports at each of the sites and connect the nvr to the cameras like that. (although i'm sure most people would advise against that)

Connect all sites via VPN then you will simply load the cameras to the NVR via IP address as if they were local.

While 2 cameras per location doesn't seem like much you are pulling 8 cameras back to site "E" 24/7 and will most likely have video issues, even if substream as this is 8 cameras 24/7 over an internet/VPN connection.
