Product Description
1TB 3.5" SATA HDD — DVR/NVR storage
A 1TB internal 3.5" SATA hard drive for use inside a compatible DVR or NVR. It suits two jobs: replacing a failed or ageing drive, or adding storage to a recorder supplied without one.
Before fitting, confirm the recorder's supported drive interface, physical drive size, and maximum supported capacity — recorder specs vary and not every model accepts every drive.
Capacity and recording time
1TB gives more headroom than a 500GB drive, but actual retention time is not a fixed figure. It depends on:
- number of connected cameras
- recording resolution and frame rate
- video compression setting
- recording schedule (continuous vs scheduled)
Motion-triggered recording reduces the volume of stored footage compared with continuous recording, extending how far back the archive reaches on the same capacity.
Fit for purpose
Suited to 24/7 continuous recording workloads in compatible home and business CCTV installations, where the recorder is designed for always-on read/write cycles. Confirm compatibility with the specific DVR/NVR model before ordering — interface type and physical size are the two checks that matter most.
Frequently Asked Questions
Will this 1TB drive fit any DVR or NVR?
Only if the recorder supports a 3.5" SATA drive of this physical size and interface — check your recorder's supported drive spec before buying.
How much CCTV footage will 1TB store?
It varies with camera count, resolution, frame rate, compression and recording schedule, so there's no single fixed duration.
Does motion detection extend storage time?
Yes, motion-triggered recording reduces unnecessary footage compared with continuous recording, helping the same capacity last longer.
Is this drive suitable for 24/7 continuous recording?
Yes, it's intended for continuous recording workloads in compatible home and business CCTV systems.
