Designating the box (CAMERA # switch)
Designating a box to a camera input means that system monitor
associates the box with a certain camera input (the designated input)
although it is physically connected to another. This causes the system
monitor to switch to the camera connected to that input when for
example an alarm is triggered or the doorbell button pressed. This gives
you the opportunity to use the shortest route when wiring a box.
The figure below shows for example a two camera system with three
accessory boxes. The switches CAMERA # are set according to the camera
(input) to which the boxes are designated.
