Motion Search
Use a Motion search to search video for motion, independently of settings made for Motion
detection. A motion search is performed using the View application. See the
Multi-Media Digital Video Recorder Remote View Operator Guide
, for procedures and tips.
Comparing Motion Detection and Motion Search
shows how a Motion search is different from Motion detection.
Motion
preview
Click Motion preview to see motion as it is detected by the unit. Colored pixels are
produced as objects move:
•
Red or green pixels indicate the detected motion is high enough to trigger an
alarm or log entry, if enabled. Adjust the sensitivity until motion that needs to be
reported shows up as green or red.
•
Blue pixels indicate that motion is detected, but not reported.
Hold
Hold is the amount of time (in seconds) that motion events are ignored for after a
motion event has triggered a report. The value is displayed when the slider is clicked.
The Hold value ranges from 1 (short) to 60 (long). The default is 15 seconds.
Log
You can set motion in a video image to trigger a log entry by adding a checkmark to
the Log box on the Video tab.
Alarm
You can set motion in a video image to trigger alarms by adding a checkmark to the
Alarm box on the Video tab. Motion is an outside world event. For other events, see
Table 7-2
