4-3.7
Display Setups. There are a variety of methods to display images as
described below:
4-3.8
Single Image Display. A single CCTV camera image is displayed. This is
best used for a single dedicated camera that is critical for monitoring. Nine inches (9
inches: 22.86 cm) is the smallest screen recommended for displaying a single camera
image.
4-3.9
Split-Screen. "Split-screen" is most commonly used to describe displaying
multiple CCTV camera images on a single display. The display screen is typically split
into a square pattern. Fifteen inches (15 inches: 38.1 cm) is the smallest sized
recommended for split screen viewing for up to a maximum of four cameras. More than
four camera images on a 15-inch display become too small to see. Figure 4-3 shows
four camera images on a single 15-inch display.
4-3.10
Matrix Displaying for Large Format Displays. LCD and flat-screen plasma
displays lend themselves to programming to show several camera images. The
configuration is best done in a square matrix (for example 9 images in a 3 by 3 matrix or
25 images in a 5 by 5 matrix). A square matrix avoids distorting or stretching the camera
image in one direction or the other as would occur in a 5 by 7 matrix configuration.
