The VPort 461A 1-channel industrial video encoder has a H.264 video compression algorithm that helps provide the best video quality on the market, but with a smaller bandwidth requirement than other video compression standards. In addition, to meet various video stream requirements, the VPort 461A can provide up to 4 video streams simultaneously using H.264 and MJPEG compression formats. Video streams can be used for different purposes, such as viewing, recording, and analysis. In addition, the rugged industrial design, which includes a -40 to 75°C operating temperature and industrial certifications, makes the VPort 461A suitable for harsh environments.
The VPort 461A is equipped with Moxa’s innovative DynaStream™ technology, which allows users to change the video frame rate automatically. With DynaStream™, users can control their network bandwidth budget and simplify network system management. The CBR Pro™ function helps to guarantee the lowest packet loss under limited bandwidth transmissions to ensure that images will not exhibit the mosaic effect.
