Moxa has introduced a single-channel full-motion MPEG-4/MJPEG industrial video encoder peripheral that works with distributed surveillance systems running Linux or Windows. The VPort 351 can provide full D1-resolution video at 30fps, and features 2-way audio and event trigger functions, the company said.

Moxa supplies the VPort 351 with Windows drivers and a “SoftDVR” Windows client application. However, the VPort's SDK (software development kit) is compatable with Linux, according to the company. Additionally, the VPort 351 appears to have a simple Web interface for standalone use with any browser.
