Planned Reliability

Maintenance for cameras, alarms, recorders, sensors and app access.

Systems drift over time. Camera views move, batteries weaken, recorders fill or fail, apps lose connection and sensors stop behaving. Regular checks keep the system useful instead of decorative.

Check recording status, storage, retention, playback and incident retrieval.

Frequently asked questions

Security Maintenance Questions, Answered.

Straight answers about CCTV servicing, alarm maintenance, app access, faults and upgrades across Sussex.

Yes. If you inherited an existing CCTV, alarm or security system, we can inspect it, test the key components and explain what is working, what is weak and what is worth improving.

A typical visit can include checking camera views, image quality, recording status, storage, cabling, power supplies, remote access, app connection and any obvious signs of damage or wear.

In many cases, yes. We can check whether the issue is with the recorder, network connection, app setup, permissions or older equipment that needs updating or replacing.

Most homes and small businesses benefit from an annual check. Higher-risk commercial sites, shared buildings or systems used every day may need more regular maintenance.

Yes. We will not recommend replacing everything unless it makes sense. Often, specific cameras, recorders, sensors, batteries or network parts can be upgraded while keeping useful existing equipment.

Yes. We support residential CCTV and alarm systems as well as commercial security systems for offices, shops, warehouses, hospitality venues, shared buildings and business premises across Sussex.
