Moxa VPort 364A-T [6/88] Overview

VPort 364A Introduction

2-2

Overview

The VPort 364A 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 364A 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 364A 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

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 364A 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 364A 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 364A meets the critical requirements of most industrial applications. Most importantly, the

VPort 364A-T can operate reliably in a -40 to 75°C temperature range. The VPort 364A-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

364A 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
