Reliable CCTV Repair for any CCTV system

Cameras offline, a black screen or a recorder that has stopped saving footage? We find the real cause and fix it, whoever installed your system.

Repairs, not guesswork

We find the fault before we replace anything

Most CCTV faults have a simple cause: a failed power supply, a water-damaged connector, a dying hard drive or a network setting that changed. Replacing cameras at random is expensive and often does not fix the problem.

Our engineers test each part of the system in turn, from the camera and cable to the switch, recorder and app, so the repair targets what has actually failed. We repair systems we did not install, including Hikvision, Dahua and Uniview, and tell you honestly if a part is not worth repairing.

FAQs

CCTV Repair questions

Straight answers to the questions we are asked most. If yours is not here, send us a message and we will reply.

Yes. Most of our repair work is on systems fitted by other installers, including Hikvision, Dahua and Uniview equipment.
Often it is, especially when the fault is a power supply, cable or hard drive. If the cameras are old analogue models, we will explain when an upgrade makes more sense.
In many cases, yes. Recovery depends on the make and model. We will tell you what is possible for your recorder.
The most common reasons are a new router, a changed password or an expired cloud setting. We reconnect the recorder and test viewing on your phone.
We avoid anything that wipes recordings where possible. If a hard drive has failed, the footage on it may not be recoverable, and we will tell you before changing it.
