Excellent video performance, 1-channel H.264/MJPEG industrial video encoders
- 3 simultaneous video streams for H.264 and MJPEG
- Video latency under 200 ms
- 2 Ethernet ports for cascade and Ethernet port redundancy
- Moxa DynaStream™ function supported for network efficiency
- ONVIF supported for standardization and interoperability
- Local storage capability with SD card slot
- Industrial design with -40 to 75°C operating temperature
- Free VPort SDK PLUS supported
The VPort 461 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 461 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 461 suitable for harsh environments.
The VPort 461 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 bandwidth-usage to network administrators.
