All matrix switchers, no matter how complicated and sophisticated they may be, depend on crosspoint switches to perform the basic operations of the switcher. The crosspoint switches from a rectangular array of rows and columns in which any row may be connected to any column.
In the figure shown above, the rows are connected to video cameras and the columns are connected to video monitors. By closing a certain crosspoint switch we may connect any camera to any monitor.
In the example above, by closing switch SW12 the camera 2 is displayed on the monitor 1. Likewise, by closing SW24 camera 4 is displayed on the monitor 2.
■Monitoring Mode
In the normal connection, this system can control up to 16 cameras, 4 monitors, and 4 system controllers. In the
There are two surveillance ways:
One is the spot mode that associates one camera with one monitor. The other is the sequence mode that sequentially displays the images through more than one camera.
●Spot Mode
The specified camera images are continuously displayed on a given monitor.
When another camera input is accepted, the images are replaced by new ones.
