Our Teradek Bolt wireless transmission system works well for sending a zero-latency SDI signal from the Steadicam rig to the switcher on a live-switched studio shoot. Wireless intercoms complete the solution, allowing the Steadicam operator to operate free of any wires, which allows a great deal of freedom of movement. The range of the transmitter is 300 feet, so dropouts are never a problem in a standard-size studio.
From a technical standpoint, we will need to be able to patch into your switcher. We will also need a genlock reference source (composite video for SD shoots, and generally HD-Y for HD shoots, depending on the camera), and a patch into your intercom system.
