Enter the number of cameras, store working hours, and storage size. The calculator will estimate
how many hours and days videos will be retained for the Minimal and Medium sections.
Formula used: cameras × 420 + 1200 MB per hour.
Days are calculated as: retention hours / working hours per day.
1 TB = 1000 GB. Current value: 2 TB = 2000 GB.

Calculation logic:
1) Space per 1 hour = number of cameras × 420 + 1200 MB.
2) Allowed volume = 95% of the total storage size.
3) For each item, its percentage of the allowed volume is used.
4) Retention hours = item volume / space per 1 hour.
5) Retention days = retention hours / store working hours per day.
This version uses decimal storage units: 1 GB = 1000 MB, 1 TB = 1000 GB.
If needed, this can be changed to binary units (1024).
