The Grandtec MAG-5000 Magic Guard USB digital video capture system uses a plug & play USB 2.0 interface to monitor and record video from up to four different inputs simultaneously 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. Alternating among images in the latter option is easy, using the included IR remote control. Since the MAG-5000 Magic Guard 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. It also has alarms when video is lost or motion is detected. 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.
