4 channel Color Quad, OSD (on screen display), VGA output, Remote Controller

Gotta say, this box works very well. Its full color, full motion. Video loop thru on the 4 video inputs. Haven't noticed any distortion or or anything. The quad views are all full motion full color. Outputs to a VGA monitor and/or video monitor. You can label your cameras for the monitor view, doesn't affect the loop thru video. For a low $100 range box, its actually kind of incredible. There's a 5th input that, although isn't used by the quad views, it acts as an input which is immediate send to the VGA/Monitor output. Its not part of the normal sequence of cameras, but selecting brings the video full screen immediately. Useful if you connect it to a device that is recording your cameras to replay that video, or for a 5th video that you want to look at occasionally.

This box is intended for security cameras, but i'm using it as a preview bus for cameras for my video switcher. Cameras plug into this box, and the outputs feed the switcher. Single VGA (or video) monitor does a quad display and lets me preview all the cameras on a single monitor.
