  • Video latency under 200 ms Industrial IP Surveillance for Mission-Critical Applications
  • 2 Ethernet ports for cascade and Ethernet port redundancy
  • Moxa DynaStream™ function support for network efficiency 
  • ONVIF support for standardization and interoperability 
  • Local storage capability with SD card slot
  • Industrial design with -40 to 75°C operating temperature



The VPort 461A 1-channel industrial video encoder with H.264 video compression algorithm provides 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 3 video streams simultaneously using H.264 and MJPEG compression formats. Video streams can be used for different purposes, such as viewing,recording, and analyzing. In addition, the industrial rugged design, which includes a -40 to 75°C operating temperature, IP30 protection, and industrial certifications, make the VPort 461A suitable for harsh environments.


The VPort 461A is equipped with Moxa’s innovative DynaStream™ technology to reduce bandwidth consumption of your video transmissions when the network is over-loaded by automatically decreasing the video frame rate. DynaStream™ can also increase video FPS when emergencies occur, offering total control of bandwidthusage to network administrators.
