Is the Seagate SkyHawk 4TB suitable for CCTV?
Yes. The ST4000VX016 is a surveillance-class 4TB CMR hard drive designed for continuous NVR and DVR video recording. Its 180TB/year workload rating, support for up to 64 camera streams and rotational-vibration sensors make it a purpose-built choice for compatible home and business CCTV recorders. Actual retention time depends on camera count, resolution, frame rate, codec, bitrate and recording schedule.

Pair this SkyHawk drive with the ANNKE N98PBK
The ANNKE N98PBK eight-channel PoE NVR offers one internal SATA drive bay and published support for drives up to 8TB. This 4TB ST4000VX016 is a storage option within that capacity limit; confirm support for your exact recorder revision before ordering.
Choose one drive for this recorder. Recording duration depends on the combined camera bitrate and recording schedule. See the N98PBK buying guide for a worked retention example, recommended cameras and setup advice. A larger hard drive increases storage capacity; it does not add camera channels.
