cold junction compensation box The measuring device (being a transmitter, DCS input card or temperature calibrator) can be measuring the temperature of the cold junction all the time and automatically perform an on-line compensation of the cold junction error. These junction boxes provide a weatherproof outdoor housing for the camera cables and connectors required by security cameras. There is typically eight to twelve inches of camera cable and power cable that needs to be housed.
