Storage covers the hard drives and memory cards that keep your CCTV footage recorded and retrievable, from 1TB single-drive setups to 12TB enterprise-grade units for busy multi-camera systems.
Most of the range is 3.5" SATA hard drives built for surveillance or server use — these are designed to write continuously, which is what a DVR or NVR needs when it's recording around the clock rather than saving occasional files like a desktop PC drive would. There's also a 128GB microSD card for smaller devices such as battery cameras or doorbells.
How to choose
- Capacity: 1TB suits a small single-camera setup with a short retention period; 8TB–12TB suits multi-camera systems recording continuously and kept for longer.
- Drive type: options here include Seagate, HP, and Lenovo enterprise/server-class drives, built for sustained read/write workloads rather than occasional use.
- Form factor: nearly all listed drives are 3.5" SATA, fitting standard DVR/NVR bays; the microSD card suits compact cameras with a card slot instead.
- Recording style: continuous 24/7 recording needs more capacity than motion-triggered recording, since footage is written far more often.
Check your recorder's maximum supported drive capacity and bay size before ordering, as this varies by DVR/NVR model.
Storage — frequently asked questions
What size hard drive do I need for CCTV?
It depends on camera count and how long you want to keep footage; this range spans 1TB for small setups up to 12TB for continuous multi-camera recording.
Can I use a normal PC hard drive in my DVR or NVR?
Standard desktop drives aren't built for constant write cycles, which is why this range focuses on surveillance and enterprise-class drives designed for 24/7 recording.
What's the difference between the hard drives and the microSD card?
The 3.5" SATA hard drives fit standard DVR/NVR bays, while the 128GB microSD card suits smaller devices like battery cameras that record directly to a card.
