Open Settings and choose Data and retention. The timeline shows each capture’s life: full evidence when it is captured, passes within the limit reduced to counts after a set number of days, and every record deleted at the end. Breaches keep everything until they are deleted.

Change the days before passes within the limit are anonymised. Plates and frames are dropped; the count stays for reports.

Keep sealed records for sets when records are deleted. Shortening it deletes older records at the next nightly run, and they cannot be recovered. Keep it in step with your data protection impact assessment.

Choose Save retention and confirm. The nightly retention run applies it.
