Gary Seven emerges from the transporter chambers fog
Gary Seven's office with the transport chamber hidden in the background.
The Transporter chamber is Gary Seven's means of transportation around the planet Earth and back to his home planet more than 1000 light years from Earth. The way the chamber works is unknown, but when in operation, the chamber produces a cloud of a blue fog-like substance that envelopes the chamber. The chamber is controlled by the Beta 5 Computer and is the first known transporter to be in use on Earth, especially given the time period of 1968 and its use for an unknown number of years before.
The transporter beam can be intercepted, by another transporter unit. This occurred when Gary Seven was in transit to Earth and his beam was accidentally intercepted by the USS Enterprise, commanded by James T. Kirk. This would seem to dictate that both transporter technologies work on similar principals, but there is no further information on the device. What is known is that Gary Seven's Transportation Chamber is more powerful than that of the Enterprise, for it was able to re-direct the transporter beam of the Enterprise back to it, and instead of Gary Seven re-materializing in the transporter room of the Enterprise, he re-materialized in the transporter chamber.
When not in use, the chamber door which resembles that of a safe when it is closed is hidden behind a shelf holding Martini glasses. The shelf and the brown wood finish surrounding it splits down the middle and slides into the adjacent walls allowing the chamber door to open. This action is achieved by actuating the right pen on Gary Seven's desk downward. (TOS: "Assignment: Earth")
