Hey everyone,
I’m working on a project to connect IP-based CCTV cameras installed at multiple remote locations to a centralized NVR over the internet. The tricky part is that these locations use SIM-based 4G/5G internet, and I need to ensure secure connectivity using a VPN. Here’s a quick rundown of what I’m trying to do:
At each remote site, I have IP cameras connected to a 4G/5G router. These routers need to act as VPN clients to securely connect to a central VPN server. At the central site, I’ve got an NVR that needs to communicate with all the remote cameras over the VPN. The NVR is connected to a high-speed internet line, and I plan to set up the VPN server on the router/firewall here. I want the connection to be reliable and secure, while also keeping bandwidth usage efficient since the remote locations depend on SIM-based internet. I might use a static IP or Dynamic DNS to make the VPN server accessible if needed.
I could use some advice on a few things:

I could use some advice on a few things:
- What’s the best VPN protocol for this setup? I’m considering options like IPSec, OpenVPN, or WireGuard, but I’m not sure which works best with SIM-based internet.
- Any recommendations for solid 4G/5G routers that are reliable and have good VPN client support?
- What’s the best way to configure the central VPN server to securely handle connections from multiple remote locations?
- Are there tips for optimizing bandwidth and ensuring redundancy with SIM-based internet?
- Would it be better to use a cloud-based VPN server instead of an on-premise one for scalability?
