CCTV Storage & Bandwidth Calculator
Estimate CCTV storage from camera count, resolution, fps, compression and retention. Compare continuous and motion recording or use measured bitrate.
Storage & NVR Calculator
Estimate recording storage and stream bandwidth.
Free calculator. No sign-in required.
- Inputs
- Camera count, recording resolution, frame rate, compression, schedule and retention. Measured bitrate is optional.
- Results
- Continuous/motion video data, usable capacity including reserve, and recording-stream bitrate.
Worked example
8 × 4 Mbit/s × 3,600 s/h × 24 h/day × 30 days ÷ (8 × 1,000,000) = 10.368 TB of video (decimal).
Continuous recording at a constant average bitrate; decimal TB. Add capacity for filesystem overhead, redundancy and operating reserve. This is not a disk or recorder recommendation.
