CCTV and remote monitoring after the PSTN switch-off
CCTV recorders, door entry, building management and remote monitoring units may report alerts over a phone line, or over broadband that depends on the old network. These are easy to miss because nobody uses them day to day.
Decisions to make
Phone line, broadband or mobile?
Find out how each system sends alerts or allows remote viewing. Some legacy broadband services also depend on the old phone platform.
Keep the system or upgrade the link
Your installer will advise whether to change the connection, the unit, or both.
Monitoring and response
If a monitoring company watches the system, confirm it still receives alerts after migration.
Inventory checklist
- Each recorder, door entry, BMS or telemetry unit and its site
- How it connects: phone line, broadband or mobile
- Installer or monitoring company and contract reference
- Remote users who need to view or receive alerts
Questions for your supplier
- Does this system use the phone line for alerts or remote access?
- What connection do you support after migration?
- Who will test alerts and remote viewing afterwards?
- Does the system have its own backup power?
Who to involve
Involve the CCTV or security installer and any monitoring company. Where systems protect people or premises, ask them to confirm and test the new path.
Power cuts and backup
Recorders, cameras and routers all need power. Ask your installer how long alerts continue during a mains failure.
Do not assume remote monitoring still works after a line or broadband change. Confirm an alert reaches the monitoring company.
This is indicative planning guidance, not certification of safety, compatibility or legal compliance. Digital phone services may fail without power. Safety-critical devices require confirmation and testing by the relevant equipment vendor; an online score or analogue adapter cannot guarantee compatibility.
Where Telappliant can help
Telappliant can review business broadband or leased-line connectivity for your sites, and separately offers scoped CCTV design, installation and remote monitoring. Where an existing system relies on an analogue line, its original installer or monitoring provider must still confirm and test the replacement path; we do not certify third-party equipment. Migration dates depend on your provider, so check yours rather than assuming one date.
