The math
GB/day = (Mbps × 0.125 × 86400) / 1000. A 4K camera at 8 Mbps records ~86 GB/day. Multiply by camera count and retention days.
H.264 vs H.265
H.265 cuts bitrate ~45% with no perceptible quality loss. A 16-camera 4K install drops from ~22 TB/month on H.264 to under 8 TB on H.265.
Recording schedule choices
24/7 continuous is the safe baseline. Business hours (~12h) cuts storage in half. Motion-only typically uses 15-30% of 24/7 depending on scene activity.
