A CCU is often used in conjunction with a remote-control panel (RCP), a [[waveform monitor]] and a [[vectorscope]] to rack and match many cameras together remotely.

Common adjustable parameters include:
* Iris (see [[aperture]])
* [[Color temperature]] filters
* [[Neutral density filter]]s
* [[Shutter speed]]
* [[Colorfulness|Saturation]]
* Master [[Gain (electronics)|gain]]
* Master black (pedestal)
* Black level trim (for red, green and blue components)
* Gain trim (for red, green and blue components)

In addition to these, there are usually options internally generating a [[test card]] for testing, return feeds or talkback. For more complex productions, preset scene files can be recalled to quickly change the settings of the camera on the fly.
