RJ-45 – Plug and connector. Used by Ken-A-Vision only on the Ceiling DocCam
II, it is the connectors on either end of the Cat. 5 cable provided
with this camera, and provides S-video, composite video, power
and RS-232 control, between the camera and the wall plate.
RS-232 – (DE-9 connector for as RS-232 interface) Found on the wall plate of the
Ceiling DocCam II and is used to connect the camera to control systems
for monitoring such as Crestron or AMX.
S-Video – Separate video, also known as Y/C (or erroneously, S-VHS and
"super video") is an analog video signal that carries the video data as two
separate signals (brightness and color), unlike composite video which
carries the entire set of signals in one signal line. [S-Video, as most
commonly implemented, carries high-bandwidth 480i or 576i resolution
video, i.e. standard definition video. It does not carry audio on the same
cable. It is a four (4) pin connector, with each signal pin paired with its
own ground pin]. Ken-A-Vision supplies two lengths of S-video cables:

USB - Universal Serial Buss a serial bus (connection) standard to interface
devices. USB can connect peripherals such as mouse devices, keyboards,
gamepads and joysticks, scanners, digital cameras, printers, external
storage, etc. For many devices such as scanners and digital cameras, USB
has become the standard connection method. [USB also replaced parallel
ports which formerly were common on computers].
USB 0.9, 1.0, 1.1 previously common specifications. KAV devices are
1.1 unless designated USB 2.0.
USB 2.0 - as of 2006 the USB specification is at version 2.0 (with
revisions). This is a higher data transfer rate than the 1.1 specification. The
USB 2.0 specification was released in April 2000 and was standardized by
the USB-IF at the end of 2001. Equipment conforming with any version
of the standard will also work with devices designed to any previous
specification (known as backward compatibility). All KAV USB 2.0
cameras are backward compatible, however there will be a diminution of
resolution and pixelization will be more noticeable.
Video - (usually a composite [RCA] connector) - Composite video is the format
of an analog television (picture only) signal before it is combined with a
sound signal. It is usually in a standard format such as NTSC, PAL, or
SECAM. [It is a composite of three source signals called Y, U and V
(together referred to as YUV) with sync pulses. Y represents the
