Need advice on deciding a sim based router to hook up my NVR to

[uminaginative]

I have a CP Plus NVR hooked up to the wired Airtel broadband at my home (independent house) that gives me security alerts on the 6 x 2mp cameras linked to it. I am now considering a sim based router to hook up my NVR to, as I am likely to be away from my home for an extended period of time (and there's no one else there). Some questions that come to mind:

• 4g vs 5g sim/router?
• Airfibre vs telco-provided routers vs telco-independent router?

Any other advice/ suggestions greatly appreciated.
