Moxa VPort 26 Introduction
1-3
The VPort 26 series support 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).
Three video streams for meeting versatile application requirements
VPort 26 is a powerful IP Camera. Aside from the high quality H.264 video compression, it can also generate a
maximum of three video streams: two 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, do
MJPEG image analysis with full D1 resolution at 10FPS, and record the H.264 video streams with CIF resolution
at 30FPS.
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.
SD Card for recording video locally when the network is down
The VPort 26 is equipped with an SD card socket (SDHC, V2.0) for local storage and offline data logging, in the
event of network interruptions. Currently, the VPort 26 supports SD cards up to 32 GB.
RTSP for easy integration with existing systems
RTSP (Real-time Streaming Protocol) is a client-server multimedia presentation control protocol, which ensures
interoperability among 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 26 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 26
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.
Easy web access using standard browsers
There is no need to install new software to access the IP camera, since the embedded web server allows users
to use any popular web browser to access the IP camera 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 image 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 IP Camera 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 26 suitable for more versatile applications.
SDK support for developers
The high-performance IP camera 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.
