The user interface is much easier to use with a ring selector similar to other compact digital cameras. The zoom control is in the form of a ring surrounding the shutter button, with the parallax control now in the form of a slider on top of the camera. 2D/3D selection is through a single button, as is the video mode.
Each connection to a telephone set required six wires from the key system: [5] One pair (two wires) carried the talk circuit (tip and ring), one pair carried control information, known as A-Leads, for that line, designated A and A1, and the third pair carried current to a lamp for the specific line key position on the telephone set (L and LG).

If digital wireless cameras are outdoors and have a clear line of sight, they typically have a range between 250 and 450 feet. If located indoors, the range can be limited to 100 to 150 feet.

The focus itself may be adjusted in a variety of ways. Larger view cameras and the like slide the lens closer or further from the film plane on rails; on smaller cameras, a focus ring on the lens is often rotated to move the lens elements by means of a helical screw. Other systems include levers on the lens or on the camera body.
A three-CCD (3CCD) camera is a camera whose imaging system uses three separate charge-coupled devices (CCDs), each one receiving filtered red, green, or blue color ranges. Light coming in from the lens is split by a beam-splitter prism into three beams, which are then filtered to produce colored light in three color ranges or "bands".
