Video Retention & Storage Calculator
Video Retention & Storage Calculator
Estimate how much storage you need for a given number of cameras and retention period. Use the default settings for a quick answer, or open advanced options to match your environment more closely.
Inputs
Advanced options (optional)
If you know the camera’s configured bitrate, enter it here for best accuracy.
Only used for motion-based recording. Typical ranges: 10–35%.
Adds extra time for event buffering, missed triggers, and bursts.
This calculator provides an estimate. Actual storage varies by camera settings (bitrate, VBR/CBR), scene motion, codec, and audio. Use advanced options for tighter sizing.

- Defaults estimate typical bitrate based on resolution, FPS, and scene complexity.
- Motion-based recording uses “motion activity percent” plus a buffer factor.
- Overhead accounts for filesystem, recording overhead, and safety margin.
