Product Description
A 2TB 3.5" SATA hard drive for CCTV recorders — it stores footage once fitted inside a compatible DVR or NVR. It's not a standalone recorder; it's the internal storage component.
Use it two ways: to replace a failing or full drive, or to add capacity to a recorder that shipped without one. Either way, check your recorder's supported drive interface, physical bay size, and maximum drive capacity before ordering — mismatched specs are the most common reason a "new" drive doesn't get recognised.
What 2TB actually gets you
There's no fixed "days of footage" answer, because recording duration depends on:
- number of cameras connected
- resolution and frame rate per camera
- video compression format in use
- whether recording is continuous or motion-triggered
More cameras, higher resolution and continuous 24/7 recording all eat storage faster. Switching to motion-triggered recording instead of continuous recording is the simplest way to stretch a 2TB drive further, since it skips long stretches of empty footage.
Before you buy
Confirm your DVR/NVR's manual lists a supported drive interface and physical size matching this 3.5" SATA drive, and that 2TB sits within its stated capacity limit.

Frequently Asked Questions
Will this 2TB drive work with any CCTV recorder?
Only if the recorder supports a 3.5" SATA drive and accepts 2TB capacity — check your DVR/NVR's manual for its supported drive interface and size before buying.
How many days of footage will 2TB store?
There's no single answer — it depends on how many cameras you run, their resolution and frame rate, the compression used, and whether recording is continuous or motion-triggered.
Can I use this to add storage to a recorder that came without a drive?
Yes, it's suitable for adding recording capacity to a recorder supplied without one, as well as for replacing an existing drive.
Does motion-triggered recording help the drive last longer?
Yes — recording only on motion rather than continuously reduces unnecessary footage, which extends how far the 2TB capacity stretches.
