How much hard disk do I need for 4 CCTV cameras?

For 4 cameras at 1080p, 15 FPS, recording 24x7 for 30 days with H.265+ compression, you need approximately 800 GB to 1 TB. A 1TB D25 Surveillance HDD is recommended and available at WeKart Online Store.

Can I use a normal hard disk in my CCTV DVR?

No. Desktop HDDs are not designed for 24x7 continuous recording and fail within 6-12 months in a DVR. Always use a surveillance-grade HDD like D25, Seagate SkyHawk, or WD Purple.

How long does a 2TB HDD record CCTV footage?

A 2TB HDD stores approximately 28-35 days of footage for 8 cameras at 1080p with H.265+ compression recording 24x7. With H.264, the same setup stores 14-18 days.

What is H.265 and how does it save CCTV storage?

H.265 (HEVC) is a video compression codec that saves up to 50% more storage than H.264 at the same quality. H.265+ used by Hikvision, Dahua, and CP Plus saves up to 70-75%. Enable it in your DVR settings to get more recording days.
