Camera Control Units

Camera control units (CCU) are used to remotely control operations such as zoom, panning, focus, and aperture. Camera control units (CCU) are typically installed in a control room or production area separate from a stage, studio area, or broadcast facility where the cameras are physically positioned.

Camera control units (CCU) are used to make remote adjustments to video cameras in a recording studio or stage area. The most common adjustments include white balance, or color temperature, which calibrates the video camera to a white object so that the color rendering of other objects is correct. Camera control units (CCU) may also adjust the aperture of the camera and make other technical adjustments. Controlling technical adjustments remotely allows the camera operator in the studio to pay closer attention to the composition of the scene. Camera control units (CCU) ensure that all cameras used are calibrated or adjusted to the same uniform standard. Camera controllers also serve as the interface between the camera and other studio equipment, including mixing boards or video switchers and power supplies. A video switcher is similar to an audio mixing console and can mix the video signals into a composite signal or add special effects.

Camera control units (CCU) can also be used to control pan, tilt, and zoom cameras. Pan, tilt, zoom cameras, or PTZ cameras, offer a wide range of movement and can be used in broadcasting, video surveillance, or video conferencing applications. Camera control units (CCU) for video conferencing or surveillance cameras include joystick devices that can operate multiple cameras, or can automate certain movements, such as providing a continuous pan that sweeps back and forth through a room. A camera control unit may also control several movements at once, providing pan/tilt actions simultaneously. Picture phone cameras or web cams may also be controlled by remote camera controller devices.
