Unit of luminance (amount of light falling on a surface).
(SI symbol: lx) The unit of measurement for illuminance (i.e., the amount of illumination) impinging upon a surface. 1 lx is the illuminance impinging upon a surface of 1 m2, each point of which is at a distance of 1 m away from a uniform point source of light of 1 cd (candela). It supersedes the foot-candle. See foot-candle; photon.

An international unit of illumination, it is the amount of uniform light falling on an area of 1 square meter and is measured in lumen per square meter - Lux Chart
Is a measure of light in terms of candle power (measured in foot candles). Lux is often given as a technical specification for cameras to describe the lowest level of light required for the camera to produce any kind of an image. However, this number lists the absolute lowest level of light needed to move ANY of the image sensor's pixels. Since humans cannot detect this change in the image or let alone make out a distinguishable picture, this manufacturer specification is often exaggerated and misleading. Although generally speaking a lower "lux" rating indicates performance in darker conditions, the number listed cannot give a real determination of real-world performance. MHz (megahertz) is a measure of frequency. 1 GHz = 1000 MHz = 10,000 KHz = 100,000 Hz.
A standard unit of illumination measurement.
A unit measuring the intensity of light. The light of a full moon is about 0.1 lux, while bright sunlight is about 100,000 lux. Basically, the lower the rating the better the camera performs at night. 1.0 lux in video means light level of a candle light. l Lux approximately equals to 10 foot-candles (1 Lux = 10.764 fc).

A unit of measurement used to rate the amount of light that is needed by a camcorder to record a recognizable image; the lower the spec, the better. Although ratings are typically in the 1 to 10 Lux range, camcorders require over 100 Lux in order to produce a quality image.
The amount of light per square meter, incident on a surface. The term applied to metric measurement of light intensity taken at the illuminated surface. One foot-candle (FT-c) = 10.76 lux, or 1 lux = 1 lumen/square meter = 0.093 foot-candles.
lux is a light sensitivity rating referring to the minimum amount of light a particular camcorder needs in order to record a viewable image. The lower the lux rating the better the camera will perform in poorly lit filming. Some Sony camcorders have a "Night Shot, Zero Lux" function that enables filming in complete darkness.

Lux is a unit of illumination equal to the direct illumination on a surface that is everywhere one meter from a uniform point source of one candle intensity or equal to one lumen per square meter. Lux is a term commonly used to show the minimum amount of light needed for a video camera to function. Many video cameras are so sensitive, that they require small amounts of light to function properly, and are referred to as "low Lux cameras". One lux is the equivalent of 1.46 milliwatt (1.46 x 103 W) of radiant electromagnetic (EM) power at a frequency of 540 terahertz (540THz or 5.40 x 1014 Hz), impinging at a right angle on a surface whose area is one square meter. A frequency of 540 THz corresponds to a wavelength of about 555 nanometers (nm), which is in the middle of the visible-light spectrum.

Matrix switcher: is a type of switcher which allows a single input to be switched to many outputs. Matrix switchers are used in large cctv (closed circuit television) systems and have many powerful features.
A camera’s light gathering ability. The lower the number, the better the image in low light conditions.
This is a measure of the amount of light striking a surface i.e. the luminus flux density at a surface. One lux is one lumen per square metre. Cameras for use in good lighting conditions, or in daylight would normally be rated at 2 lux or more. Cameras with a Lux rating of 0.2 Lux or less would be considered low-light cameras. It is not possible to get good colour definition in low light levels, so in general low light cameras are always monochrome. However, day/night cameras use electronics to switch from colour during the daytime to monochrome during night or low light conditions. Many low light cameras are also infra-red sensitive, so that infra-red illumination can be used. Particularly useful in zero light conditions.

One lux is equivalent to a candlelight. This is a measure of the amount of light a camcorder will perform adequately in. For instance, zero lux indicates that the camcorder is capable of recording in "night vision" mode using infrared pickup. However, take note that such light ratings are far from standardized as not all manufacturers use the same scale or the same testing methods.
