Storage retention calculator for camera bitrate planning.
Convert bitrate and storage into rough retention days, then use the result to choose NVR bay count and drive capacity.
Storage Inputs
Use average sustained bitrate for planning.
Retention Result
Daily Write
337.5 GB/day
Estimated Retention
24.3 days
Assumption
This calculator assumes continuous recording and no RAID or formatting overhead. Real-world retention may be lower.
Continuous recording assumptions are conservative. Motion-only systems may retain footage longer, but only if the scene is actually quiet.
Once you have a retention target, use the planner to validate the camera, recorder, and storage combination together.
