Digital Cameras A digital camera looks and behaves like a regular camera, except instead of using film, it stores the image it sees in memory as a file for later transfer to a computer. Many digital cameras offer additional storage besides their own internal memory; a few sport some sort of disk but the majority utilize some sort of flash card. Digital cameras currently lack the resolution and color palette of real cameras, but are usually much more convenient for computer applications.

Monitors A computer display, monitor or screen is a computer peripheral device capable of showing still or moving images generated by a computer and processed by a graphics card. Monitors generally conform to one or more display standards. Sometimes the name "display" is preferred to the word "monitor", as the latter is perceived to be ambiguous alongside the other senses of "monitor" meaning "machine-level debugger" or "thread synchronization mechanism". Computer displays are sometimes called heads, especially when talking about how many are connected to a computer. Computer displays have also been known as visual display units or VDUs.

Network Cameras

Portable Audio A digital audio player (DAP) is a device that stores, organizes and plays digital music files. It is more commonly referred to as an MP3 player (because of that format's ubiquity), but DAPs often play many additional file formats. Some formats are proprietary, such as MP3, Windows Media Audio (WMA), and Advanced Audio Codec (AAC). Some of these formats also may incorporate digital rights management (DRM), such as WMA DRM, which are often part of paid download sites. Other formats are patent-free or otherwise open, such as Vorbis, FLAC, and Speex (all part of the Ogg open multimedia project).

Video Cameras A camera which contains an electronic image sensor rather than photographic film. The lens focuses an image on an electronic tube or CCD chip. A camera has electronic circuitry which generates color and sync pulses. Most portable consumer camcorders are equipped with a full complement of audio circuitry, e.g., microphone, audio amplifier and additional audio electronics. In order to obtain better quality images, a professional camera has three tubes or a triple CCD system, one for each primary color. Most professional cameras have a genlock input, which allows the camera to be synchronized to an external source. Some cameras also include basic character generators for titling purposes.

Video cards A graphics card or video card is a component of a computer which is designed to convert a logical representation of an image stored in memory to a signal that can be used as input for a display medium, most often a monitor utilising a variety of display standards. Typically, it also provides functionality to manipulate the logical image in memory.
