2TB - HDD 3.5" SATA Hard Drives – Free Installation with Any CCTV Kit or Package -Ideal for 24/7 continuous recording

2TB 3.5" SATA HDD for DVR/NVR internal fitment — a bare storage drive, not a standalone recorder, supplied for install into a compatible recorder chassis.

Use case is either of two jobs on site: swapping a failed or full drive, or populating a recorder that shipped with no storage installed. Before specifying it on a job, confirm the recorder's supported drive interface, physical bay size and maximum supported capacity — mismatches here are the usual reason a correctly-sized drive isn't picked up by the DVR/NVR.

Capacity planning

2TB is the raw figure; actual retention is not fixed and depends on:

• number of camera channels recording
• resolution and frame rate per channel
• video compression format
• continuous vs motion-triggered recording schedule

More channels, higher resolution and continuous 24/7 recording all consume the 2TB faster. Configuring motion-triggered recording instead of continuous extends retention by cutting unnecessary write volume — a useful lever when a client's recorder can't take a larger drive.

Compatibility check before ordering

Confirm interface (SATA), physical size (3.5") and the recorder's stated maximum drive capacity against this spec before fitting — this is standard practice for both home and business CCTV installs.</description_md> [{"q": "Is this drive a full recorder, or just storage?", "a": "It's an internal 2TB 3.5" SATA hard drive for fitting inside a compatible DVR or NVR — it is not a standalone recorder."}, {"q": "How many days of footage will 2TB give me?", "a": "There's no fixed figure — it depends on camera count, resolution, frame rate, compression and whether recording is continuous or motion-triggered."}, {"q": "Can I use this to replace a failed drive in an existing recorder?", "a": "Yes, it's suitable for replacing an existing drive, provided the recorder's interface, physical size and capacity requirements match."}, {"q": "Will motion-triggered recording extend how long footage is retained?", "a": "Yes, motion-triggered recording reduces unnecessary write volume compared to continuous recording, helping extend retention on the same 2TB capacity."}]
