CCTV / NAS
CCTV + NAS storage calculator
Estimate storage, RAID capacity and uplink from actual camera bitrate and recording conditions.
2. Theoretical estimates
Camera aggregate / uplink—
Raw daily storage before headroom (SI)—
Raw 30-day storage before headroom (SI)—
Retention requirement + headroom—
RAID usable capacity—
Estimated retention—
—
Warning: RAID is not a backup. Filesystem, metadata and vendor-reserved space can reduce actual capacity.
Calculation basis
Mbps × 1,000,000 ÷ 8 × seconds → bytes
1 GB = 1,000,000,000 bytes · 1 TB = 1,000 GB
