


Sensor events : If you want sensor events to trigger event recording, select the sensors you want to
function as triggers. For example, select S1 to use Sensor 1 as a trigger.



Activator events : If you want activator events to trigger event recording, select the activators you want to
function as triggers. For example, select A1 to use Activator 1 as a trigger.
Note: VMD is not automatically selected when it is enabled. Furthermore, if none of the sensors or activators
is selected, and VMD is not selected, no recording will take place.

CAUTION:
When you update the quality or size values of a camera in this screen, all the recorded video from
this camera that is currently stored on the storage media is deleted.
Advanced Recorder Settings
Advanced settings allow you to customize the recorder's video quality settings. You can choose whether or not
recordings are automatically erased to make room for new recordings, and set the allocation of disk space among all
the recorders connected to the Video Gateway unit.
When advanced settings are activated, you can choose to record larger VGA or D1 frames, or smaller QSIF or
QCIF frames, and you can select custom quality settings. Quality is defined by a bitrate/framerate pair. The
following table summarizes the recommended settings and the approximate disk usage at each setting. The
recommended settings for the SIF and CIF frames are the standard settings used by the system if you do not
customize the settings.
