Accessing VPort 2140 Video Server for the First Time
Camera View selection
A maximum of 4 cameras can be connected to the VPort 2140 at the same time. Users can view
the image of each camera by selecting “Video 1,” “Video 2,” “Video 3,” and “Video 4,” or
selecting “Video All” to view all images in Quad screen.
In Quad viewing mode, the maximum image size is only 352 x 240 (NTSC) or 352 x 288 (PAL)
for each camera, in order to fit the monitor screen.
System Configuration
There is a button or text link on the left side of the system configuration window that only appears
on the administrators’ main page. For detailed system configuration instructions, refer to Chapter
4, System Configuration.
Relay Output Control
VPort 2140 Video Server has 4 DI and 2 DO for external devices, such as sensors and alarms. If
external devices are attached to the digital output, administrators or permitted users can click on
Open to short the Common and Normal Open pins of the digital output, or click on Close to
short the Common and Normal Close pins of the digital output.
Motorized (PTZ) Camera Control
If a serial device, such as a motorized camera, is attached and correctly configured to the COM
port, the control panel will appear on the permitted users’ main page. The effective buttons will
change color when the cursor is passed over the button. Users can control the pan, tilt, zoom, and
focus functions of motorized cameras. The home button is used to return the camera to the center
position if the camera supports this command. Apart from near and far control for focus, an
AUTO button is provided for setting auto focus mode. To move the motorized camera more
precisely, the speed control for pan and tilt allows users to fine tune the aiming position. Users
can also click directly on any point in the image to force the motorized camera to focus on that
point, or select a preset location from the drop-down. The list of preset locations is pre-defined by
administrators. The detailed configurations are described in the related section in Chapter 4,
System Configuration.
Custom Camera Commands
There are a maximum of five buttons that can be set to custom commands for users to control the
attached motorized (PTZ) cameras, in addition to the default pan, tilt, zoom, and focus controls.
Custom commands are set up by administrators, and are used for functions such as activating or
deactivating the wiper of dome, according to the attached motorized device’s User’s Manual of.
