IP Whitelisting on Cellular: The UK Installer’s Complete Guide

IP whitelisting requires a stable source IP. CGNAT makes this impossible on cellular. Everything UK installers need to know.

IP whitelisting only works if the connecting device has a consistent, known public IP. CGNAT gives your device a shared, changing IP — whitelisting is impossible. Speedroute assigns a dedicated static IP that works with every monitoring centre, aggregator and management platform.

What to tell your monitoring centre

  • The Speedroute static IPv4 address
  • NVR brand and model
  • NVR remote port: Hikvision 8000 / Dahua 37777 / Hanwha 4520
  • The IP behaves identically to any other static IP
  • The IP will not change for the duration of the installation
