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

4CIF 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.
