Hello everyone, let's see if someone can help me and give me ideas to be able to do what I need. My company is dedicated to putting CCTV cameras, now we have started to install cameras for the towns. Now I have a project that consists of 3 towns being 1 town the main one and the other two towns I would like to be able to record the cameras in the NVR of the main town, these are in a different network. What would be the best way to do it? Put a router in each town and connect them via VPN? The problem I have is that being the city council network the same does not let me open ports... there is the Any way to connect using a tunnel or something like that? Then apart from what I have commented on, as we have facilities for many towns, there is some way to set up a network species with VPNs configured to be able to access from our office, a to the local network of each town? since from Remote it does not allow the same configuration options as locally the NVR. Is it possible to mount a VPN server in our office to be able to connect approximately 100 clients?
