A 4TB 3.5" SATA drive at 7200 RPM, built for the write-heavy, always-on workload of continuous CCTV recording. The SATA III interface handles high-speed data transfer, which matters when multiple channels are writing simultaneously across a recording schedule.

Fitting it into a job

This drive is compatible with all DVR and NVR surveillance systems, so it slots into an existing recorder without a compatibility check. It's ideal for 24/7 continuous recording rather than motion-only capture, which suits sites running full-time retention policies. Outside CCTV, the same drive works in desktops, servers, NAS devices and external enclosures, so it's a stock item worth holding for general storage jobs as well as recorder installs.

Supply state

When ordered alongside any CCTV kit or package, this drive is supplied fully installed and ready to go before dispatch — no need to open the recorder chassis on site to fit it yourself.
