VIDEO-FG-4 interface card
This is a PCI card with four NTSC/PAL video inputs on it, presented on standard BNC connectors on the
side of your Dewetron system. With this option and DEWESoft-PROF level software, you can acquire and
display up to four video streams simultaneously in sync with your data.
It accepts standard composite colors (PAL, NTSC) or monochrome video formats (CCIR, EIA).
The supported resolution is programmable and includes square-pixel (640 x 480 or 768 x 576) and broad-
cast resolution. Before captured images are transferred to the PC’s memory, images can be scaled down
using available selectable ratios.
