AC operation only: If you are wiring more than one Camclosure to the same transformer, connect one side of the transformer to the red wire on all units; connect the other side of the transformer to the black wire on all units.

NOTE: Failure to connect all AC powered units the same way will cause the cameras to be out of phase with each other, which may produce a vertical roll when switching between cameras.
