Decimator DMON-4S Quad (3G/HD/SD)-SDI to HDMI Multi-Viewer

The DMON-4S is a flexible bridge between four (3G/HD/SD)-SDI sources and four mini HDMI displays. Each of its four HDMI outputs can show any one of the four SDI inputs or a multi-view of all of them, so it doubles as a quad SDI-to-HDMI converter and a 1-to-4 multi-viewer. Configure it as four independent SDI-to-HDMI converters, three converters plus a quad-split output, two converters with loop-through, or a single input feeding all four HDMI outputs.

The inputs handle both 3G level A and B, and the multi-view mode adds an 8-channel audio metering overlay per window with individual enables, custom position, and size. Each window supports horizontal and vertical flipping along with scaling and cropping for precise placement. An easy-to-use LCD and button system handles setup without a computer, making it a compact tool for monitoring several cameras on affordable HDMI screens.
