This digital video capture system uses a plug & play USB 2.0 interface so that you can monitor and record feed from up to four different video signals on your computer's hard drive. You may also view the feeds on a TV monitor in either a quad display that shows all four images at once, or a dual display consisting of a main image with a small picture-in-picture window. Since the 4-Camera Color Quad works with virtually any type of camera, you're not limited to certain brands. This 4-Camera Color Quad can automatically save such data as date/time and brightness/contrast/saturation/hue for each camera. The preview window size is adjustable, and you can even define the environment you do not wish to observe by adjusting mask area and sensitivity.
