Moxa VPort 364 Industrial Video Encoder
Introduction
2-2
Overview
The VPort 364 is a 4-channel industrial video encoder that supports the H.264 video compression algorithm,
which provides the best video quality on the market while requiring less bandwidth compared to other video
compression standards. In addition, the VPort 364 provides dual video streams in both H.264 and MJPEG
format simultaneously. The two video streams can be independently configured to achieve an ideal video
quality and bandwidth optimization, such as different quality settings for viewing, recording, or analyzing video.
Rugged and industrial features, such as a -40 to 75°C operating temperature, IP30-rated form factor, and
industrial certifications make the VPort 364 perfect for harsh, industrial environments.
High Performance H.264/MJPEG compression
Video input can be efficiently compressed into H.264/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.
Dual video streams for meeting versatile application requirements
VPort 364 is a powerful video encoder. Aside from the high quality H.264 video compression, it can also
generate a maximum of dual video streams: one H.264 and one MJPEG simultaneously, to meet the needs of
specific applications. For example, the user can view the h.264 video streams with full D1 resolution at 30FPS
and record the MJPEG video streams with CIF resolution at 30FPS.
Moxa DynaStream™ for network efficiency
DynaSteam
TM
is a unique and innovative function that allows for adaptive frame rates in response to events on
the network, such as event triggers and system commands. When network traffic becomes congested,
DynaStream™ allows VPort products to respond to CGI, SNMP, and Modbus commands from SCADA and
automatically decrease video frame rates to reduce bandwidth consumption. This reserves bandwidth for the
SCADA system to maintain Quality of Service (QoS) and guarantees that the SCADA performance will not be
impacted by video traffic. For example, the frame rate can be set low during regular streaming to reduce
bandwidth usage and automatically switch to a high frame rate during triggered events to ensure quick
transmission of critical video data or video streams, or to provide detailed visual images for problem analysis.
Low video latency: under 200 ms (milliseconds)
For some mission-critical applications, low video latency is one of the key requirements. For example, highway
transportation systems monitor very fast moving vehicles; videos displayed at the central traffic control center
need to reflect the latest traffic conditions. Therefore, the video latency must be under 200ms.
2-way audio supported for a complete surveillance solution
The VPort 364 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 364 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
364 meets the critical requirements of most industrial applications. Most importantly, the VPort 364-T can
operate reliably in a -40 to 75°C temperature range. The VPort 364-T is an optimal solution for outdoor and
harsh environments.
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
364 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.
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
