Product Description
The 500GB 3.5" SATA Hard Drive for CCTV DVR/NVR Replacement (SKU HDD-500GB-Pre-installed) is the internal disk a compatible DVR or NVR writes its footage to. It is ideal for 24/7 continuous recording.
Jobs it covers
- Replacement: swap out a failed or worn drive in an existing recorder.
- Bare recorders: add recording storage to a DVR or NVR supplied without a drive.
For retail premises, warehouses, offices and residential blocks, it suits recorders whose supported drive interface, physical size and hard drive requirements match a 3.5" SATA disk.
Selection checklist
- Capacity: 500GB
- Interface: SATA
- Form factor: 3.5" internal
- Recorder check: confirm the supported drive interface, physical size and hard drive requirements of the DVR or NVR before ordering
Sizing retention
The number of days 500GB holds is set by the job, not the drive. Four factors decide it: the number of cameras, video resolution, frame rate and compression settings, along with the recording schedule. Motion-triggered recording conserves space compared with continuous recording, so on a multi-camera site the schedule is the first thing to review when retention needs to stretch.

Frequently Asked Questions
Can this drive be used in any CCTV recorder?
Only in a DVR or NVR that takes a 3.5" SATA drive. Check the recorder's supported drive interface, physical size and hard drive requirements first.
Can it replace a failed hard drive?
Yes. It can go into a compatible DVR or NVR as a replacement drive, or add recording storage to a recorder supplied without one.
How much footage can a 500GB drive hold, in days?
It depends on the number of cameras, resolution, frame rate, compression settings and recording schedule. Motion-triggered recording uses less space than continuous recording.
