Racks / engineering

Most production trucks contain a patch panel

In this area, the professional video cameras are controlled using camera control units (CCU) by multiple vision engineers, to make sure that the iris is at the correct level and that all cameras look the same. These operators shade, balance, and focus the cameras from this position inside the vehicle. This area is controlled by an operator called a V1 (vision supervisor in the UK) and depending on the size of the show may have multiple V2s. This area is also where the majority of the racked technical equipment is stored, including the video router and converters.


Engineer In Charge (EIC) – a broadcast engineer who has a great deal of knowledge about the truck than anyone else on the production. They are involved in installing all required equipment, having the correct skills needed to fix and maintain the equipment. EIC’s usually stay on one truck for years learning all the intricacies about each machine and how to fix them in difficult situations.[23]

Vision engineer (also known as a video technician or camera shader) – The vision engineers are in charge of all the cameras’ iris and overall look of the camera’s video. The vision engineers also troubleshoot issues that may arise with the cameras and cable length.


Broadcast reference monitor – used to monitor the output of cameras and the transmission for confidence checking

Video router – send video and audio to any destination from any source.

Frame synchronizer – puts Asynchronous or “wild” video sources into Synchronization with other video signals.

Test cardSignal generator – used for checking signal paths and troubleshooting.
