Why has my CCTV stopped recording?

Check the recorder first — the hard drive may be full (if overwrite is not enabled) or it may have failed. Also check the recorder has power. These account for most recording failures.

How long do CCTV hard drives last?

Surveillance-grade hard drives typically last 3-5 years under continuous recording. Standard desktop drives used in budget systems may fail sooner.

Can I check my CCTV remotely?

Most modern systems allow remote viewing via a smartphone app. If remote viewing has stopped working, the issue is often the internet connection at your property or a change in your router settings.

Do I need to comply with any laws for home CCTV?

If your cameras capture images beyond your property boundary, you must comply with UK GDPR and the Data Protection Act 2018. This includes putting up signs and handling any subject access requests.

What's happening?

Home CCTV systems in the UK typically consist of cameras (wired or wireless), a DVR/NVR recorder, and sometimes cloud storage. When the system stops working, you lose both live viewing and recording capability, leaving your property unmonitored.

What usually causes it?

DVR or NVR recorder has lost power or crashed
Hard drive in the recorder has failed
Camera power supply failure
Network or Wi-Fi issue (for IP and wireless cameras)
Cable damage between camera and recorder
Camera lens or sensor fault

Is it dangerous?

A CCTV system that is not working presents no electrical safety risk. However, your property is left unmonitored. If the system stopped working after a lightning strike or power surge, other electrical equipment may also be affected.

Can I fix it myself?

Check the DVR or NVR has power and is turned on — look for lights on the front panel. Restart it by turning it off and on. Check the monitor or TV it connects to is on the correct input. For Wi-Fi cameras, check your router and the camera's Wi-Fi connection. For wired cameras, check the power supply to each camera.

When should you call an electrician?

Call an electrician if the recorder will not turn on, if cameras have no power and the supply is hardwired, if the hard drive has failed and needs replacing, or if the system stopped working after a power surge or lightning strike.
