NTSC and PAL are the two coding systems for television signals, each other, they are totally incompatible. NTSC is mainly used in the United States, while the PAL system is one that is typically used in Europe. PAL: 720 x 576 pixels and 25 frames per second NTSC: 720 x 480 pixels and 29.9 frames per second.

The lux (symbol lx) is the derivative unit of the International System of Units for the illuminance or lighting level. Equal to one lumen/m². It is used in photometry as a measure of luminance, taking into account the different wavelengths by the luminosity function, a standard model of the light sensitivity of the human eye.

Closed circuit television, or CCTV (stands for closed circuit television) surveillance is a technology designed to monitor a variety of environments and activities. It is called closed, that, contrary to what happens with the media, all components are linked. In addition, unlike conventional television, this is a security system designed to

An Active Pixel Sensor (APS) is a sensor that detects light based on CMOS technology and therefore known as CMOS sensor. Because CMOS technology is possible to integrate more functions on a sensor chip, such as brightness control, contrast correction, or an analog-digital converter. Advantages

Much lower power consumption

Economic (requires few external components)

If readingtaneous higher number of pixels

The digital converter may be integrated on the same chip

Blooming low ("Smear") or no

Greater flexibility in reading (faster preview, video, ...)

The pixels can be exposed and read simultaneously

Other possible topologies (the SuperCCD Fujifilm sensor employs a panel-shaped construction (octagonal) forpixels)

Different types of pixels (depending on size and sensitivity) combined

High frame rate compared to a CCD of the same size

In the diagram we can see: 1) photo-diode. 2) Amplifier. 3) metal wire. 4) Output signal. 5) Light.

CCIR is a committee responsible for regulating the Spanish radio in space, this committee is responsible for standardization to operate in Spain.

CVBS is the acronym by which composite video is often referred to. The idea of this definition means Color, Video, Erase and Synchronized.

The most widely used cable is the already known coaxial cables with a BNC connector or RCA connector.

The RCA (Radio Corporation of America) connector is a connector used to send video signals or audio.
This is a circular two-contact connector; signal and ground, used with coaxial cables. Each signal uses a single cable and to differentiate color coded RCA connector on the set.

Inside the different types of connectors for power supply we find one of the most common, the DC jack. Used in most connections in electronic devices such as routers, laptops, printers etc ... is the most used due to its easy assembly and connection. These connectors are mostly used in DC power supplies and installations.
The connector is cylindricalAnd we find its version in male and female format (A). The male connector is composed of the outer and inner metal part, where in each of them the energy travels, normally the inner part is used for the positive pole and the outside for the negative, but may vary according to manufacturer.
This type of connector is found in many diameters, the most common are 3.5mm and 5.5mm. Although we can andThere are several measures in terms of length and outer or inner diameter.
Its installation is simple, we can find several types of connectors, pair to weld or to screw with terminal block, it will depend on the user to choose the most suitable in its installation.
When purchasing the male connector to perform a repair we must know its diameter, length of the connector and internal diameter. If we proceed with aTo new installation only we must make sure that the male and female connector are of the same characteristics.
