Estimate how much recording storage your CCTV / NVR setup needs. Enter your camera count, resolution and retention period — the calculator uses the industry-standard bitrate model (1 Mbps ≈ 0.45 GB/hour) and adds 10% headroom.

100% = continuous recording · ~40% = typical motion-triggered recording.

Skip the on-prem disks — ArcisAI Cloud VMS scales storage automatically with STQC-certified, India-hosted recording.
Estimates only. Actual storage varies with scene complexity, frame rate, GOP and VBR/CBR settings. For the most accurate figure, enter your camera's actual configured bitrate in the override field. Calculation: cameras × bitrate(Mbps) × 0.45 × hours/day × retention days × density, +10% headroom; 1 TB = 1000 GB (decimal).
