Most CCTV problems that appear as sudden failures are caused by smaller issues building up over time, such as unstable connections, storage warnings, misconfigured schedules or time drift. In Tow Law, Durham, planned CCTV servicing helps confirm that monitoring is reliable across entrances, yards, loading areas and internal high-risk zones. We start by confirming recording and playback behaviour, checking for gaps, dropouts and storage health warnings. This includes reviewing NVR/DVR performance, verifying retention settings, and confirming that playback is stable across recent time windows. If footage export is required for your organisation, we also confirm that evidence can be retrieved in a usable format rather than discovering an export issue during an incident. A common cause of repeat faults is connectivity. Servicing checks include confirming network and PoE stability, reviewing switch and port behaviour where accessible, and testing for intermittent link drops that create cameras offline or unstable feeds. This structured approach helps separate a camera fault from an upstream issue such as cabling, power, network configuration or a recorder port problem. We work in a way that supports facilities teams, not disrupts them. Checks are planned to minimise disruption to operating hours, and any issues found are explained clearly, with practical options if parts or upgrades are needed. This maintenance structure helps reduce repeat callouts, avoids preventable downtime, and keeps your CCTV system predictable for day-to-day security oversight.
