I have a Hikcision CCTV system which is currently setup via a BT based broadband connection. Due to where I live the fastest service I can get is around 25mb down / 5mb up.
I'm contemplating movng to a 4G based home broadband service - my phone line was recently damaged due to building works and I found myself using 4G as my primary internet access including working from home full time. I have good 4G access here and my speeds are consistently 60mb+ down / 20mb+ up with latency comparable to my landline broadband.
I'm considering moving to an entirely 4G based broadband service however I understand most services (Three would be my provider of choice) are CG-NAT based with either no option for a public IP, or a prohibitive subscription cost. I also work from home regularly and rely on VPN use for that.
Ignoring my work requirements for now, as I'm in the process of changing jobs right now, what are my options regarding the CCTV? Hikvision provide a dDNS type service which resolves the need for a static IP however connecting to the cameras remotely still relies on access to the NVR via a public IP and port forwarding on my router.
