Why 30 days is the baseline
Theft, injury claims and employee disputes rarely reach management the same week. A 7 or 14 day retention window sounds acceptable until the claim arrives on day 20 and the footage is gone. Sizing for 30 days at the outset costs far less than adding storage after an incident.
How to control storage cost
Use motion or event-based recording on low-traffic cameras, keep continuous recording on choke points, and choose H.265 compression. These three choices routinely cut required storage by half without sacrificing the footage that matters.
