Moxa Technologies VPort 2140 COM 1 & COM, Modulation, Default Video Source, RS-232 RS-485 Speed

System Configuration

size = 30%, then the system will only detect the motion of objects that occupy an area larger than 30% of the total monitored area; the motion of objects with size less than 30% of the monitored area will NOT be detected.)

2.Sensitivity sets the measurable difference between two sequential images to indicate motion.

A larger object size and lower sensitivity will cause the VPort to ignore small variations in images. When the motion amplitude of some objects in the monitored screen exceeds the settings, a white letter M with red background color will appear in the upper-right corner to the window.

Motion detection is provided as a reference because it is environment-dependent. When the settings are configured to be very sensitive to motion, some triggered events might be false alarms, since in fact there is only a tiny difference between sequential images. False alarms can be triggered by the flashing of florescent lights, shifting of shadows, etc.

Before completing the Video configuration, 3 items need to be confirmed.

Modulation

There are 3 types of Modulation. Administrators can set the auto-detected condition during initialization by selecting Auto, but can still set it manually by selecting NTSC or PAL. When you change the camera modulation, a warning message will pop up to inform you that the system will restart to validate the new modulation.

Although the analog cameras have 2 different standards, NTSC or PAL, all of the cameras connected to VPort 2140 Video Server should use the same standard.

Default Video Source

Administrators can set the default viewing mode for web home page in camera 1, 2, 3, 4, or all in quad.

Save the modification

After all necessary modifications are made, click on Save to store the modifications. If you have changed the modulation type, the VPort will automatically restart. If the Reset network at next boot option is checked, perform the software installation again. Otherwise, the VPort will boot up automatically using the new configuration settings.

COM 1 & COM 2

There are 2 COM ports, COM 1 and COM 2, in VPort 2140 Video Server for connecting the external devices, such as Motorized PTZ controller, Modem, or Multiplexer.
