Though 4K is most commonly used when referring to the number of pixels on a display screen, it’s increasingly used to describe the number of pixels–and now resolution–of high-end security cameras.
4K, as you will see below, actually refers to the number of pixels across the image or display. It would also make for a really low resolution in modern terms. However, in this context 4K does not mean a total of 4,000 pixels. To start in the same spot we did with the meaning of “MP”, we should mention that “K” comes from the French, and their nomenclature for the metric system, who borrowed it from the Greeks as prefix for “kilo”–meaning “thousand”.
#4K SECURITY CAMERA 1080P#
In case it comes up at your next office party in a conversation about which security cameras to buy, 4MP security cameras have 3,939,840 pixels, compared to a standard 1080p television which has only 2,073,600 pixels. 4MP cameras offer a higher video quality than 1080p models, allowing your 4MP security camera image to capture more video information for the area it’s watching–and is perhaps a better tool when it comes to identifying intruders or other security threats. The most common 4MP resolution is 2592 pixels wide by 1520 pixels high, which could also be expressed as 2592 x 1520. Therefore a 4MP security camera image is composed of roughly 4 million pixels. A Megapixel (MP) should be thought of as a unit of graphic resolution that’s equivalent to roughly one million pixels. Let’s first start with the pixel–a pixel can best be described as the smallest controllable element of a picture represented on the screen, or a minute area of illumination on a display screen, one of many from which an image is composed. “Mega”, which is short for “million”, and “pixel”, which is the shortened combination of “picture” and “element”. “MP” is the amalgamation, so to speak, of two words. But at the end of the day, and after some math to do the translations, you will discover “MP” and “K” are just different abbreviations to express the number of pixels on an image, which will always be listed using a length by width format. Though this language is becoming dated because as you will notice, the language in which we use to talk about security cameras and their resolutions is changing. Using that analogy, we could say “MP” is the language of camera lenses, while “K” is the language of display screens. The difference between referencing resolution in terms of “MP” or using measurements expressed in “K” is a bit like the difference between saying “Hello” and “Hola”. What’s the difference between a resolution listed in “MP” and “K”? Here are answers to the most commonly asked questions about security camera image resolution and storage. …And other questions about comparing security camera resolutions, such as 4K vs 4MP, that you’ve been dying to have answeredĭo you ever feel like your security camera technician is speaking a foreign language when they start talking about image and display resolution? When it comes to the world of security camera systems, you’ve probably read a lot about 4 megapixel (MP) cameras, 4K cameras, and HD cameras–but what does it all mean, how do those different camera resolutions compare? Have no fear, we’re here to break it down into terms you can understand.
