Track types

Long play tracks
LP tracks are usually large ring buffers. They are used for current
recording. One LP track is assigned to each camera.
Secure tracks
Secure tracks are usually relatively small ring buffers. One secure
track can be assigned to each camera. The recording settings for
secure tracks may differ from those of a LP track.
These secure tracks will be saved as soon as an alarm is triggered
on the recorder (see Installation and Configuration). This prevents
the current pictures from being overwritten. New secure tracks will
subsequently be created in which the recording is continued.
Saved tracks
Saved tracks are secure tracks that have been protected against
overwriting after an alarm had been triggered. Depending on the
number of triggered alarms, more than one saved track may exist
for each camera.
Reference track
Single images of the cameras are stored in the reference track.
These images can be used to compare current camera settings
and positions with the original conditions. Reference tracks are
therefore not used for recording or playback.
