Describe the problem clearly
Note which camera, channel or service is affected, when it started and whether power, network or recording changed at the same time. A photo of the model label and recorder screen can make the first discussion more useful.
Check the whole system
A blank image can come from power, cabling, a network path, a camera, recorder settings or storage. Avoid replacing a camera before the connection and recorder compatibility have been checked.
Plan an upgrade when repair is not practical
For older systems, compare the cost and availability of a replacement recorder, cameras, storage and configuration. Keep the existing model numbers and cable type so a proposed upgrade can be assessed accurately.
Common questions
Can you repair an existing CCTV system?
Bring the camera and recorder model numbers and describe the fault. The appropriate repair or replacement path depends on the equipment, cabling and symptoms.
What should I bring to the showroom?
Bring photos of model labels, a description of the affected channels, any error messages and details of recent power or network changes. Do not include passwords in an enquiry email.
