The ONVIF specification ensures interoperability between products, regardless of manufacturer. Moxa is an ONVIF user member, and With hundreds of cameras in an integrated system with IP surveillance and other systems (such as SCADA), it is important to control the size of a video stream so that it does not flood over to the common shared network and consume too many system resources, which could disrupt critical system operation or data transmission. Moxa has developed a revolutionary DynaStream™ function, which can control the video frame rate, and has introduced it into all VPort series products automatically. Once an event is detected, such as a DI alarm, network traffic jam, etc., the system can automatically reduce all VPort video frame rates so that they will consume fewer resources and less bandwidth, or increase all VPort video frame rates to increase video performance. This is done with CGI commands, SNMP, or Modbus/ TCP. This new tool is extremely flexible. Not only can it change system CBR Pro™ is an advanced bit rate flow control technology that limits the transmission bit rate based on a user’s network bandwidth. This function is designed to secure the video stream transmission to provide better image quality by eliminating the dropped packets VPort SDK PLUS is a user-friendly SDK (software development kit) that adds VPort video streams to any type of third-party software, such as NVR, VMS, and SCADA. For wide compatibility, the SDK supports three major technologies: • CGI commands: These URL commands are used in HTML and web systems, which are very popular platforms for video surveillance software. most VPort IP video products support ONVIF specifications for simpler and faster integration with ONVIF-compatible third-party software. resources and network bandwidth so that critical data systems can maintain Quality of Service (QoS), but it can also guarantee that system performance will not be impacted by video streams. that occur when the peak bit rate exceeds the bit rate allowed by the network bandwidth. • Eliminate image packet loss • Increase network efficiency • Available with all Moxa IP cameras • ActiveX Control SDK: ActiveX Control is an OCX component that is used widely in platforms that support WIN32, IE Plug-in, and Visual Basic, and is also popular in automation system software, such as SCADA systems. Moxa ActiveX Control SDK PLUS is a user-friendly, customized tool for programmers that supports versatile parameters for customized viewing, recording, PTZ camera control, event triggering, and recorded video playback. • API SDK: The API SDK, which includes a detailed C library, can be used to program customized solutions in a Visual C++ or C# environment. The API SDK includes a total of 4 DLL modules, and currently supports the WIN32, Linux, and WIN CE pocket 2003 platforms.
