The WIPP Repository Transparency Demonstration monitors the environment and materials in underground storage. There are two principal parts, a video monitoring system, "NTVision", and a general purpose monitoring system called the Material Monitoring System (MMS).

• The MMS currently measures environmental values on the surface and underground: temperature, air movement and air pressure, humidity and precipitation (surface only). In addition, a "T1" sensor, attached to a simulated waste drum, measures for motion. 

• The NTVision system collects images from two cameras.  When the video system detects changes to a scene, it captures a series of images, which are stored for analysis.  These images can be combined to create a movie of the event. This movie is displayed to users graphically on a monitor using web-based tools.
