Product Description

A 1TB 3.5" SATA hard drive for internal fitting inside a compatible DVR or NVR. It exists to solve one of two jobs: replacing a drive that's died, or adding storage to a recorder that arrived without one fitted.

Why capacity matters: the drive gives more room for footage than a 500GB unit. How long that footage actually lasts on the drive isn't fixed — it depends on how many cameras are recording, the resolution and frame rate you've set, the video compression in use, and your recording schedule.

One practical way to stretch it

Setting the recorder to motion-triggered recording rather than continuous can reduce how much gets written to disk, which helps footage stay on the drive for longer before it's overwritten.

Before you buy

This drive won't work in every recorder. Check three things on your DVR or NVR first:

  • Drive interface — confirm it takes a SATA connection.
  • Physical size — confirm it takes a 3.5" drive.
  • Capacity support — check the recorder's maximum supported drive size.

If any of those don't match, the drive either won't fit or won't be recognised properly, so it's worth confirming against your recorder's manual rather than guessing.

Frequently Asked Questions

Will this drive fit any DVR or NVR?

Only if the recorder supports a 3.5" SATA drive and can handle 1TB capacity — check your recorder's specification before ordering.

How many days of footage will 1TB store?

There's no fixed figure — it depends on the number of cameras, resolution, frame rate, compression and your recording schedule.

Can I use this to add storage to a recorder that shipped without a drive?

Yes, this drive is suitable for fitting into a compatible recorder that was supplied without one.

Does motion-triggered recording help the drive last longer before footage is overwritten?

Yes, recording only on motion rather than continuously can reduce how much is written, extending how far back footage goes.
