Overview
The VPort 451 is a 1-channel industrial video encoder featuring MPEG4 and MJPEG video
compression, which can provide a maximum of three video streams (two MPEG4, one MJPEG)
simultaneously. The video streams can be usedfor different purpose, such as viewing, recording or
analysis. In addition, video latency under 200 milliseconds makes the VPort 451 an optimal
solution for mission-critical video applications in which the real-time video display essential. The
industrial-rugged design with -40 to 75°C operating temperature, built-in fiber Ethernet ports, IP30
form factor protection, and industrial certifications make the VPort 451 more suitable for
deployment in harsh environments.
High Performance MPEG4/MPEG4 compression
Video input can be efficiently compressed into MPEG4/MJPEG video stream packets in real time.
This is done without sacrificing remote monitoring capability or storage. Five levels of
compression quality and four different image resolutions provide greater versatility.
Three video streams for meeting versatile application requirements
VPort 451 is a powerful video encoder. Aside from the high quality MPEG4 video compression, it
can also generate a maximum of three video streams: two MPEG4 and one MJPEG simultaneously,
to meet the needs of specific applications. For example, the user can view the MPEG4 video
streams with full D1 resolution at 30FPS, do MJPEG image analysis with full D1 resolution at
10FPS, and record the MPEG4 video streams with full D1 resolution at 20FPS.
Video latency under 200ms (milliseconds) for more real-time video
In some mission critical environments, low video latency is a key requirement. For example, a
highway transportation system monitors vehicles that are moving very quickly. The video display
in the traffic control center needs to reflect actual current traffic conditions. Therefore, the video
latency must be under 200ms.

VPort 451 User’s Manual Introduction
1-3
2-way audio supported for a complete surveillance solution
The VPort 451 supports both audio input and audio output for voice over IP communication
between a field site and central site. The 2-way audio function not only saves time, but also saves
the cost of needing to add additional communication devices (such as a phone).
Rugged design for industrial environments
The VPort 451 is an industrial video encoder, which means that it is designed for harsh industrial
environments. With the 12/24 VDC and 24 VAC redundant power inputs, IP30 protection, and
DIN-Rail mounting, the VPort 451 meets the critical requirements of most industrial applications.
Most importantly, the VPort 451-T can operate reliably in a -40 to 75°C temperature range,
making it the first video encoder of its kind that can be used for extreme temperature,
industrial-grade applications. The VPort 451-T is an optimal solution for outdoor environments. In
addition, the VPort 451 has received important industrial and safety approvals, such as UL508,
making the VPort 451 well suited for transportation, utility, and manufacturing systems.
Two Ethernet ports for cascade networking and port redundancy
The VPort 451 has two built-in 10/100 Mbps Ethernet ports for cascading multiple VPort 451
units. With the cascade feature, you’ll need fewer switch ports, and also reduce the complexity of
your cable layout. Port redundancy can be used to build a backup path for video transmission in
case the primary path is broken.
SD Card for recording video locally when the network is down
The VPort 451 is equipped with an SD card socket (SDHC, V2.0) for local storage purposes,
which currently can support SD cards up to 32 GB. Enable local storage to record events that
occur when the network is down and the video stream cannot be transmitted.
Modbus/TCP supported for convenient communication with SCADA/HMI
Most automation applications use SCADA/HMI systems to monitor and control field site devices
and equipment. Many SCADA/HMI systems now require real-time video for remote monitoring,
and for this reason, the VPort 451 supports the Modbus/TCP protocol, which enables direct
communication between the VPort and the SCADA/HMI system, allowing administrators to easily
determine the status of their VPorts for maintenance purposes.
Supports serial-to-Ethernet communication for connecting a serial device
In addition to video cameras, surveillance systems also use other devices, such as sensors and card
readers. The VPort 451 provides one serial-to-Ethernet RS-232/422/485 COM port for simple,
low-cost installation of serial devices.
RTSP streaming for easy integration
RTSP (Real-time Streaming Protocol) is a client-server multimedia presentation control protocol,
which enables the interoperability of video devices and software. Hardware or software that
supports RTSP streaming can easily identify and decode the video stream without the hassle of
codec installation. For example, users can view video images from the VPort 451 directly with
Quick Time and VLC, both of which support RTSP streaming.
Multicast (IGMP) transmission for network efficiency
Transmitting digital video images via an IP network requires many times the bandwidth required
for transmitting general data. For this reason, the efficiency of network bandwidth management is
one of the most important factors that determine the performance of a video over IP surveillance
system. The VPort 451 supports multicast transmission with the IGMP protocol, which can reduce
the bandwidth requirements when multiple clients access the same video stream, and greatly
increases the efficiency of network bandwidth management.

VPort 451 User’s Manual Introduction
1-4
Easy web access using standard browsers
There is no need to install new software to access the video encoder, since the embedded web
server allows users to use any popular web browser to access the video encoder from anywhere
over the Internet. As long as you are connected to the network, you will be able to view the same
images seen by your cameras.
Built-in 3 area-selectable Video Motion Detection (VMD)
External sensors are not required, since the video channel can be configured to detect motion in 3
areas, making it easy to set up a security system either in your office or in the field. And the
customizable settings allow you to tune the system for both object size and sensitivity, making the
video encoder adaptable to different environments.
Weekly schedule for automated surveillance
The user-defined time period will check security settings on a weekly basis, and send notifications
or drive external devices, making the VPort 451 suitable for more versatile applications.
Flexible I/O control for external devices
2 opto-isolated sensor inputs and 2 relay outputs are provided to control external devices, giving
system integrators the option of turning an analog system into an advanced security system.
SDK support for developers
The high-performance video encoder can be integrated into many applications—without busting
your budget—and the complete programming interface of the Moxa VPort SDK PLUS makes the
developer’s job easy and straightforward. To ask about SDK requirements, please contact a Moxa
sales representative for details and an application form.

RJ45-to-DB9 cable or RJ45-to-DB25 cable to connect the VPort 451’s console port to your PC’s
COM port. You may then use a console terminal program, such as Moxa PComm Terminal
Emulator, to access the VPort 451’s console configuration utility.
Reset Button
A recessed RESET button is provided for rebooting and restoring the system to the factory default
settings. Use a pointed object, such as a straightened paper clip or toothpick, to press the reset
button.
1. Reboot:
To reboot the VPort 451, power it off and then power it back on again, or push the RESET button
one time. The STAT LED will light in red as the POST (Power On Self Test) process runs. When
the rebooting process is finished, the STAT LED will turn green.
2. Restore to Factory Settings:
A recessed RESET button is provided for restoring the system to the factory default settings.
When the system fails to install properly, or operates abnormally, use the RESET button located
on the top panel of the VPort 451 to restore the factory defaults.
To do this, use a pointed object such as a straightened paper clip or toothpick to hold down the
reset button, and then release the reset button when the STAT LED stops flashing in red. At this
point, the POST process will run, and the VPort will reboot. The STAT LED will turn green when
the VPort has finished rebooting.

in the box. In addition, you will need access to a notebook computer or PC equipped with an
Ethernet port.
Step 1: Select the power source
The VPort 451 can be powered by a 12 to 32 VDC DC power input, or a 18 to 30 VAC AC power
input. Two power inputs are provided for redundancy. Users can check the LED status located in
the front panel to see if the power inputs are connected appropriately. If one of the power inputs
fails, the FAULT LED will light up in red if the power failure alarm is enabled.
NOTE The VPort 451 series support power input specifications of 12-32 VDC for 12/24 VDC power
input, or 18-30 VAC for 24 VAC power input (note that this is different from Moxa EDS
switch’s 12-45 VDC power input). The maximum power consumption is around 5.5 watts.
Step 2: Connect the VPort 451 to a Network
The VPort 451 has 2 auto-sensing 10/100 Mbps RJ45 Ethernet ports, or 100 Mbps fiber optic ports
(multi mode or single mode) for network connectivity. Both the RJ45 and fiber optic ports have
separate LEDs for 10 Mbps and 100 Mbps connections.
Step 3: Connect the VPort 451 to a camera and an audio source
The VPort 451 has 1 VIDEO INPUT ports. Use the BNC connector (1.0 Vpp, 75Ω) and coaxial
cable to connect video cameras to the VPort to input analog video signals.
The VPort 451 has 1 audio input and 1 audio output. A microphone or an amplifier can be plugged
directly into the AUDIO INPUT port, and a speaker can be plugged into the AUDIO OUTPUT
port.
NOTE One VIDEO LED is located on the VPort 451’s front panel to indicate the video signal
transmission status for video inputs. Check the LED status to see if the video is working
properly.

Step 4: Connecting motorized PTZ cameras and serial devices
The VPort 451 has 2 RS-232/422/485 ports. One is a COM PORT with a DB9 male connector,
and the other is a PTZ PORT with a 5-pin terminal block connector. Both ports can be used for
connecting PTZ control cables to control PTZ cameras over the TCP/IP network.
In addition, the COM PORT with the DB9 male connector can also be used to connect general
serial devices, such as card readers, for transmitting serial data over a TCP/IP network. This port
can be used to connect serial devices to the VPort 451 (however, the port cannot be used to
connect video cameras).
To enable PTZ control, users should configure the PTZ control protocol in the web-based
manager.
