BasicsQTC Camera 100 General Description - 6QTC Camera 100 General DescriptionThe video camera is a CCD image sensing device capable ofworking in a variety of light conditions and providing videoimages to the video input of the computer. The externalpackage provides a means of stable positioning in acomputing work environment, while allowing the user toposition the camera for a variety of image captures.Each pixel has a color filter and lens over it. The lenseswiden the effective photo diode light sensing area, makingthe CCD more light sensitive.

BasicsQTC Camera 100 Connections - 7QTC Camera 100 ConnectionsWith the exception of the Macintosh Quadra 840 & 660 AV,Power Macintosh 7500 and 8500, this camera is connectedto the back panel of a Power Macintosh AV model “S videoconnector” via a single cable conveying the video signalfrom the camera and the 12V DC supply to the camera. Onlythe Power Macintosh 7100AV and 8100AV uses theintegrated power/video cable.The Power Macintosh 7500 and 8500 use the separate RCAto RCA cable and S-Video to power cables. The Quadra 660AVand 840AVA use the RCA to RCA cable with a 12 Volt poweradapter.
