How to use this result
Enter an average bitrate from the intended camera settings or manufacturer estimator. Variable scenes can exceed an optimistic average, so leave headroom.
Core relationship
Storage follows aggregate megabits per second multiplied by recording time and retention.
Why headroom matters
Recorder databases, variable bitrate, exports and drive behaviour reduce practical usable capacity.
Important: Validate capacity against the selected recorder, drive limits, codec, retention policy and real test recordings. Do not use storage capacity to decide a lawful retention period.
