Recording includes
You can specify whether, in addition to video data and metadata (for example alarms, VCA

searches of recordings easier but it requires additional memory capacity.
CAUTION!
Without metadata, it is not possible to include video content analysis in recordings.

Retention Time

You can specify the retention times for recordings. If the available memory capacity of a
medium has been used, older recordings are only overwritten if the retention time entered
here has expired.
NOTICE!
Make sure that the retention time corresponds with the available memory capacity. A rule of
thumb for the memory requirement is as follows: 1 GB per hour retention time with 4CIF for
complete frame rate and high image quality.
