Código IP (International Protection)
The IP code classifies and rates the degree of protection provided against the intrusion (including body parts such as hands and fingers), dust, accidental contact, and water by mechanical casings and electrical enclosures. It is published by the International Electrotechnical Commission (IEC). The digits (characteristic numerals) indicate conformity with the conditions summarized in the tables below. Where there is no protection rating with regard to one of the criteria, the digit is replaced with the letter X. an electrical socket rated IP22 is protected against insertion of fingers and will not be damaged or become unsafe during a specified test in which it is exposed to vertically or nearly vertically dripping water. Another example is the Sony Xperia Z Ultra, one of the first cellular phones to be IP-rated; it is rated at IP58 and marketed as "dust resistant" and can be "immersed in 1.5 meter of freshwater for up to 30 minutes".

Balance de blancos
Technique in photography and image processing, which involves a global adjustment of the intensities of the colors (typically red, green, and blue primary colors). An important goal of this adjustment is to render specific colors – particularly neutral colors including white – correctly.

Tipo de disparador de la cámara
Indicates if the camera shutter is mechanical or electronic.
Electrónico
Velocidad de obturador
Determines the length of time the shutter lets light pass through the lens to the CCD. Shutter speed and aperture together determine exposure.

Sensor de la imagen
Escaneado progresivo
Also referred to as noninterlaced scanning, this is a way of displaying, storing, or transmitting moving images in which all the lines of each frame are drawn in sequence. This is in contrast to interlaced video used in traditional analog television systems where only the odd lines, then the even lines of each frame (each image called a video field) are drawn alternately.Progressive scan is used for DVDs and HDTV (high defintion television).
Tipo de sensor
A sensor is a convertor than measures a physical quality (light, temperature etc.) and displays this electronically on a device.
CMOS

Intervalo de longitud focal
Measure of how strongly the system converges or diverges light. For an optical system in air, it is the distance over which initially collimated rays are brought to a focus. A system with a shorter focal length has greater optical power than one with a long focal length; that is, it bends the rays more strongly, bringing them to a focus in a shorter distance.For an optical system in air, the effective focal length (f and f′) gives the distance from the front and rear principal planes (H and H′) to the corresponding focal points (F and F′).

Máxima resolución
The maximum number of pixels that can be displayed in the image. It is usually quoted as width × height,: for example, "1024 × 768" means the width is 1024 pixels and the height is 768 pixels.
1920 x 1080 Pixeles
Total de megapixeles
A megapixel (MP or Mpx) is one million pixels, and is a term used not only for the number of pixels in an image, but also to express the number of image sensor elements of digital cameras or the number of display elements of digital displays. For example, a camera that makes a 2048 × 1536 pixel image typically uses a few extra rows and columns of sensor elements and is commonly said to have "3.2 megapixels" or "3.4 megapixels", depending on whether the number reported is the "effective" or the "total" pixel count (as opposed to the 2048 × 1536 = 3,145,728 finished image pixels).
