Alternatively, one can follow the so-called “star pattern,” where each camera is independently linked to the controller. Many camera systems allow for “daisy-chaining,” such that only a single “home run” connection is required back to the controller. This is a serial-based protocol that is typically carried over an RS-232 or RS-422 interface. Different camera systems use different control protocols, though VISCA is one of the most common.
You will need a controller along with a way to monitor video from each camera. Camera ControlĪlthough PTZ cameras are regarded as “robotic,” they are not autonomous-they cannot (yet) track a subject all on their own. The operation of PTZ cameras used in a video production environment can be broken into two concerns: camera control and video switching. PTZ cameras are also a great option for live events in venues where cameras can be permanently installed or where mounting spots are available. They are sometimes employed for video conferencing where camera control or multiple camera angles are required. PTZ cameras are commonly found in settings such as academic lecture halls and houses of worship.
