Features and Benefits
- Industrial design with -40 to 75°C operating temperature and fiber optic Ethernet port
- Video stream up to 120 frames/sec at CIF (352 x 240) resolution
- Modbus/TCP supported for easy communication with SCADA software
- One RS-232/422/485 COM port for controlling external serial devices over Ethernet

Introduction
The rugged Moxa VPort 254 is a 4-channel industrial video encoder that provides up to 120 FPS at CIF resolution (NTSC: 352 x 240; PAL: 352 x 288), and supports an optional MJPEG/MPEG4 algorithm, making it especially well suited for use with distributed surveillance systems in critical industrial applications. In addition, the VPort 254 supports serial-to-Ethernet and Modbus/TCP communications for integrating automation systems, and 2-way audio is provided to allow real-time communication between system administrators located at a central site and engineers in the field.
Rugged design for mission-critical industrial environments
- Operates reliably in -40 to 75°C environments (T models)
- Built-in single-mode or multi-mode fiber optic Ethernet port (media converter not required)
- More reliable with redundant 12/24 VDC and 24 VAC power inputs
- Metal form factor with IP30 protection against dust
- DIN-Rail mounting installation suitable for industrial environments
- UL508 certified for industrial environments
Advanced network protocols for 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
