In order to control the layout from the command center, there are four wired security
cameras that give us a full view of the layout. They are also equipped with infrared
units so that they work in extreme low light conditions. The cameras are hooked
to a DVR unit which allows us to view all the cameras on one screen. It also allows
the movement of the trains to be filmed and played back. There is also a camera
mounted to a flatbed car behind any engine that show the POV of thelayout. The
feed can also be streamed or saved.
