1TB CCTV Hard Drives

A 1TB drive is 1000GB, enough for a few cameras or an older DVR that cannot take anything larger. Four are listed: a Western Digital Green Power, two Seagate 3.5 inch SATA drives and a pre-installed 1TB disk. None is a surveillance-series drive; those start at 4TB.

1TB CCTV hard drives

A 1TB drive is 1000GB. It suits a small system with a few cameras, or an older DVR that needs a replacement disk and does not accept anything larger. Check the recorder's manual for the largest size it supports and for a free 3.5 inch SATA bay.

What these drives are

The 1TB drives in this range are standard 3.5 inch SATA models from Seagate and Western Digital, and a pre-installed 1TB disk. None of them is a surveillance-series drive. The Seagate SkyHawk and Toshiba S300 surveillance drives we list start at 4TB. If the recorder will run all day, every day, and takes a larger disk, choose a surveillance drive.

How much will it record?

The length of recording depends on the number of cameras, the resolution and the recording mode, so a disk that suits two cameras may fill quickly with eight.
