Since the last partition can never be bigger than the available hard disk
space, the percentage figure can only show the maximum amount of
memory available.
The beginning and end of the recording depending on time is defined via the
"Configuration / Events / Period" or manually on the "Recorder" page.
Ring Buffer
The ring buffer provides the possibility of recording pre event images in addition to
the post event images.
The storage space assigned to the partition is subdivided into equal "ring buffers".
The Convision V6xx A continuously records images on the first ring depending on the
preferences. Once the storage space of the ring buffer has been used, the image
data are overwritten.
If an event occurs (refer to Chapter 9.3), the previously recorded images are not
overwritten but the remaining ring buffer will be filled. Then this ring is locked, and the
next ring buffer is selected.
Figure 49: Setting up a ring buffer partition
1. Define the size of a ring buffer by entering a time in the first field. You can select
"Seconds" or "Minutes".
2. Now define what portion of the total recording time should be used for storing
images prior to an event. The remaining time will be used for recording images
following an event.
3. Now specify into how many ring buffers the partition is to be subdivided, i.e. how
many events you want to record.
4. Select the recording speed from "25 Images / 1 Second" to "1 Image / hour (3600
Seconds)".
