Configuration (continued)
6 Type Select an archive type.
For most applications, it is advisable to set up a
separate archive for each camera. This enables a
fast search in the image archive later.
Ring archive Ring archive: The images are saved one after the
other. If the ring archive is full, the storage process
begins all over again. The oldest images are over-
written. A history ring can be assigned to a ring ar-
chive so that the images that triggered the alarm are
also saved.
Alarm archive Alarm archive: The alarm archive contains the im-
ages recorded after triggering of the alarm. The
alarm archive is not overwritten. A history ring can
be assigned to an alarm archive so that the images
that triggered the alarm are also saved.
History ring History ring: The images are saved one after the
other. If the history ring is full, the storage process
begins all over again. The oldest images are over-
written. A history ring must be assigned to a ring or
alarm archive. Because of the way the history ring
works, no rapidly repeating triggers may be allocated
to it, as is the case for example with sensor cam-
eras, PIR movement detectors and door contacts.
The usage of pre–alarm images is recommended for
rapidly repeating triggers. Pre–alarm images can be
set–up in Job macros/save.

assigned.
Assign complete
history ring The history ring will be assigned completely to an
alarm or ring archive.
only assign x his-
tory ring images Only the number of images entered will be assigned
to an alarm or ring archive.
Notes:
The purpose of the history ring is to save a detec-
tor’s images only when at rest. If a significant event
occurs, e.g. a hold–up alarm, the images from the
history ring are copied into the assigned alarm or
ring archive. This process enables a quick recon-
struction of the event because the alarm archive as-
signed contains the images that triggered the alarm
as well as the images after the hold–up.
