FACTOID #53: If you thought Antarctica was inhospitable, think again - its land area is only ninety-eight percent ice. Reassuringly, the other 2% is categorised as "barren rock".
Analog video is a term that can refer to any of three analog television (picture only) transmissions signals. These three signal types include: composite video, s-video, and component video. With each of these signals, only the visual element of video is transmitted, including the luminance (brightness) and chrominance (color) of the image. Look up Video in Wiktionary, the free dictionary. ... Analog television (or analogue television) encodes television picture and sound information as an analog signal, that is, by varying the amplitude and/or frequencies of the signal. ... Composite video is the format of an analog television (picture only) signal before it is combined with a sound signal and modulated onto an RF carrier. ... S-Video (also known as Y/C) is a baseband analog video format offering a higher quality signal than composite video, but a lower quality than RGB and component video. ... Three RCA cables are often used to carry analog component video Component video is a type of analog video information that is transmitted or stored as two or more separate signals. ... Luminance (also called luminosity) is a photometric measure of the density of luminous intensity in a given direction. ... Chrominance (chroma for short) comprises the two components of a television signal that encode color information. ...
Analog video is used in both consumer and professional applications. However, higher quality signal formats have been adopted, including serial digital interface (SDI), Firewire (IEEE1394), and the various other signals for carrying HDTV. Serial Digital Interface (SDI), standardized in ITU-R BT.656 and SMPTE-259M, is a digitized video interface used for broadcast grade video. ... FireWire (also known as i. ... A 6-Pin Firewire 400 connector FireWire (also known as i. ... High-definition television (HDTV) means broadcast of television signals with a higher resolution than traditional formats (NTSC, SECAM, PAL) allow. ...
Analog recording can still be argued to be little reliable due to the fact that a videotape (mechanical) drive system is not likely to "crash" like a computer hard drive or operating system might, risking some or all data to irretrievable loss.

A5: Video motion detection is a relatively new technology which attempts to replace external motion sensors and physical switches to achieve 'alarm' (or action-only) recording.
The three formats for baseband video signals — native primaries, component, and composite — form a hierarchy that is the basis of all video, whether analog or digital, broadcast or graphic.
The Video formats are also called color spaces in digital literature, and the encoding/decoding process is called color-space conversion to distinguish it from the analog process.
In analog, it takes the form of a non-linear amplifier where one of the gain resistors around an op-amp is replaced by a real or a piece-wise equivalent to a non-linear impedance.
