Recording includes
You can specify whether, in addition to video data, audio data and metadata (for example
alarms, VCA data and serial data) should also be recorded. Including metadata could make
subsequent searches of recordings easier but it requires additional memory capacity.
5.24 Advanced Mode: 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.
Retention time Camera 1 / Retention time Camera 2
Enter the required retention time in hours or days for each recording. Recording 1
corresponds to Stream 1, Recording 2 corresponds to Stream 2.

CAUTION!
Without metadata, it is not possible to include video content analysis in recordings.

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.
