  • Moxa VPort 461 1-channel H.264 Industrial Video Encoder for IP surveillance

Features and Benefits 

  • 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 with H.264 and MJPEG compression format. Video streams can be used for different purposes, such as viewing, recording, and analyzing, and the industrial rugged design, which includes a -40 to 75°C operating temperature, IP30 form factor protection, and industrial certifications, make the VPort 461 suitable
for harsh environments. The VPort 461 is equipped with Moxa’s innovative DynaStream™ function for decreasing the bandwidth consumption of your video transmissions. DynaStream™ can reduce or increase the video frame
rate automatically to make the video stream controllable by the system and system adminstrator.



Rugged Design for Mission-critical Industrial Environments 
  • -40 to 75°C wide operating temperature
  • 2 Ethernet ports for cascade and port redundancy
  • 1  RS-232/422/485 COM port for controlling external serial devices over Ethernet
  • Redundant 12/24 VDC and 24 VAC power inputs for greater reliability
  • Metal housing with IP30 protection against dust
  • DIN-Rail mounting installation for industrial environments
  • UL60950-1 certified for hazardous locations

  • Meets NEMA TS2, Section 2 requirements
Advanced Network Protocols Support Efficient Network Transmission and Integration
  • Modbus/TCP for easy communication with SCADA software
  • Standard RTSP (real-time streaming protocol) video streaming for easy integration
  • Multicast (IGMP) protocols for efficient network transmission
  • SNMPv1/v2c/v3 MIB-II for easy network management
  • QoS (ToS) for configuring the transmission priority of video streams
  • UPnP, DDNS, and IP filtering supported
Two Ethernet Ports for Cascading and Port Redundancy

The VPort 461 has two built-in 10/100 Mbps Ethernet ports for cascading multiple VPort 461 units. With the cascade feature, you'll need fewer switch ports, and also reduce your cable layout effort. Port redundancy can be used to build a backup path for video transmission in case the primary path is broken.

SD Card for Storing Video Locally when the Network is Down

The VPort 461 is equipped with an SD card socket (V2.0) for local storage purposes. Enable local storage to record events that occur when the network is down and the video stream cannot be transmitted.

Transparent PTZ Control for Easy Control of PTZ Cameras

The VPort 461 uses Moxa's Real COM technology to implement transparent communication for RS-232/422/485 PTZ control. The benefit of the Transparent PTZ Control function is that it eliminates the need to build the PTZ control driver into the VPort product, allowing the use of a legacy PTZ control panel or keyboard to control a PTZ camera directly.
