Connecting multiple GE 16X PTZ cameras in parallel
If you choose to daisy chain multiple cameras in the field, leave all camera termination switches off except for
the last camera in the chain which should be on (
Figure 9 ). The cameras may not function properly if they are
not terminated correctly.
Note: If you are connecting only one GE 16X PTZ Camera to the junction board, you must set the termination switch to ON.
