6.5.3 Retention Time
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.
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
VGA for complete frame rate and high image quality.
Enter the required retention time in hours or days for each
recording. Recording 1 corresponds to Stream 1; Recording 2
corresponds to Stream 2.
