SoftDVR™ Lite/Pro User’s Manual Application Settings
If administrators wish to configure each camera with same settings, click on Apply to All
Cameras.
3. With SoftDVR Pro, administrators have more selections for recording MJPEG video images.
Frame/Second (up to): Administrator can choose the maximum recorded frames/second in
MJPEG video servers to optimize recording results, including storage space and video
playback frame rate.
Compression: MPEG4 and MJPEG compression methods can be used to optimize recording
outcomes. MPEG4 compression means requiring more system resources, but takes less
storage space. MJPEG compression is the opposite.
4. If the recording mode is chose as Motion Detect, the warning message “Camera X hasn’t set
up the motion area yet!” will pop-up to inform the administrator to set up the VMD (Video
Motion Detection) function if it hasn’t been done.
To configure VMD settings in SoftDVR™ Pro, administrators first need to select VMD area
by marking blocks in Select the VMD Area, and tune the sensitivity in Motion Detection
Sensitivity Tuning. VMD compares the change of pixels between the pre and post video
images. When the change is over the sensitivity’s setting, the system will trigger the alarm. In
addition, there are some other functions can be used to help with VMD settings. Mark Area
can change the color of the area line to make it clearer if the image color is close to the color
of the area line. The + - buttons can be used to enlarge and diminish the selected area.
The Reset button can clear all the selected areas in the image.
In SoftDVR Lite, there is no Select the VMD Area function. Its VMD function compares the
change of pixels of the full image. So, only the Motion Detection Sensitivity Tuning is
provided.
If administrators wish to configure each camera with the same settings, click on Apply to All
Cameras.
NOTE
VMD is designed to help users build an intelligent video surveillance system, but the variations
are very different for different environments, which greatly influences VMD performance. For
example, using different lighting or lenses will result in different VMD results for the same
environment. For that reason, users should tune the sensitivity in the range of 1 to 10 to determine
the optimal result in the application environment. Also, users can use DI/DO devices
accompanied with VMD to make the video surveillance more intelligent and precise.
NOTE
Light and shadows may generate false alarms. To eliminate this kind of noise, try selecting
different VMD areas. In addition, some video cameras generate undesired noise in poor lighting
conditions. To prevent false alarms, you need to reduce the noise sensitivity, improve the lighting
conditions, or improve camera performance.
5. Click on OK to save settings and go back to the Main Window. To activate the Recording
function, click on the Recording button.
