Motion detection
Motion detection is one of the most important features of a DVR. With it there is no
need to manually search through hours of video recordings to find an event. TVR 20
can be set up to trigger an alarm if it detects motion and to record it. You can then
search these recorded motion activities for specific incidents (see “Searching video by
events” on page 56 and “Searching video by motion ” on page 57).
Select the level of sensitivity to motion as well the target size so that only objects that
could be of interest can trigger a motion recording. For example, recording is
triggered by the movement of a person but not that of a cat.
Mask out any areas of motion on the camera display
that you do not want to trigger
recording such as a flag on a pole or a moving tree.
Note: For motion detection to work best the light in a camera area should be
constant, and the background of the camera image should preferably be high-
contrast.
Motion detection can be set up for each camera individually or the settings of one
camera can be easily copied to other cameras.
