CCTV storage calculator
How much recording storage do you need?
Estimate usable disk capacity from camera count, configured bitrate and retention—not resolution labels alone.
Actual storage changes with scene complexity, codec implementation, variable bitrate, frame rate, motion activity and camera settings.
Important: All calculations and recommendations are preliminary estimates for planning and educational purposes only. Actual requirements and costs vary with site conditions, equipment specifications, installation complexity, environmental factors and customer requirements. A professional site assessment and quotation are recommended before purchasing or deployment.
