Retention is a system setting
Storage depends on how many cameras record, how much detail they capture, the frame rate, compression, image complexity, motion, and whether recording is continuous or event-based.
Plan with operating reserve
- Choose a target number of days.
- Use realistic camera settings.
- Include future cameras.
- Leave reserve instead of sizing to a perfect laboratory estimate.
Verify after installation
The Plan a System calculator produces a planning estimate. Actual retention should be checked after the cameras have operated in their real scenes.
