Features and Benefits
- Industrial design with -40 to 75°C operating temperature and fiber optic Ethernet port
- Video stream up to 30 frames/sec at full D1 (720 x 480) resolution
- Pre/post-alarm video recording function for advanced surveillance
- 2-way (1 in/1 out) audio supported

- Free VPort SDK PLUS provides CGI Commands, ActiveX Control, and an API library for system integrators and third-party software developers
Introduction
The Moxa VPort 351 is a high performance, 1-channel industrial video encoder that provides up to full D1, full frame rate performance (NTSC: 720 x 480 @ 30 FPS; PAL: 720 x 576 @ 25 FPS) and supports a dual MJPEG/MPEG4 algorithm, making it especially well-suited for use with distributed surveillance systems in critical industrial applications. In addition, a continuous pre/post event trigger video record function can help system administrators determine why an alarm was triggered, and 2-way audio is provided for the convenience of real-time communication between system administrators located at the central site, and engineers in the field.
Rugged design for mission-critical industrial environments- -40 to 75°C wide operating temperature
- Built-in single mode or multi mode optical fiber Ethernet port; no media converter required
- UL508 and Class 1, Div. 2 (Pending) certified for hazardous locations
- Redundant 12/24 VDC and 24 VAC power inputs ensure greater reliability
- Metal form factor with IP30 protection against dust
- DIN-Rail mounting installation for industrial environments
Advanced network protocols support efficient network transmission and integration
- 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
The VPort 351 adopts Moxa's Real COM technology to implement transparent communication for RS-232/422/485 PTZ control. The benefit of this transparent PTZ control function is that it eliminates the need to build a PTZ control driver into the VPort product, since legacy PTZ control panels or keyboards can be used to control the PTZ camera directly.
