|For security professionals, 4K image detail means that video can be magnified and examined down to the slightest detail. It also allows users to simultaneously monitor a large area and a specific object with a single camera in applications like city surveillance and transportation. Users can also more effectively monitor tiny movements in confined spaces such as exchanges at bank counters or gaming tables at casinos requiring high attention. 4K changes the world of video security – Security redefined by 4K.|
What is 4K ?
|4K is the description given for any video, digital cinematographic material, streamed content with about 4000 pixels from side to side. Because most video content today is about twice as wide as it is high, we can say that 4K has about 2000 pixels from top to bottom. These are approximate numbers and there are several versions of 4K, but in its simplest form it delivers an image four times the overall quality of high definition, and about 16 times the quality of standard definition.|
Higher than high definition
The benefit to the increased numbers of pixels found in a 4K image can be easily explained when looking at a still image. When you take a section of a larger 4K image the increased number of pixels captured means that objects displayed inside it are more defined compared to a high definition image. This makes it easier for the user of the image to identify content within it, as its content is less blurred.
What experience does Sony have in 4K technology?
This year’s FIFA World Cup the games were shot in 4K with our range of broadcast cameras and Sony Pictures has been filming blockbusters in 4K for around 5 years, so 4K is not a new technology for Sony. We are well established in offering 4K in the consumer market too, through our acclaimed home entertainment systems and we anticipate the number of homes with a 4K TV to grow as further content is developed and more people experience the image quality at cinemas, where 4K is a growing trend.
What could 4K mean for Video Security?
With positive experience of 4K in the broadcast, D-Cinema and consumer businesses, Sony believe that 4K offers major benefits and opportunities to the Video Security industry, not least by being the next resolution standard in the security industry. Needless to say, the biggest advantage of 4K is higher resolution. Resolution-wise, one 4K camera can capture 4 times what a Full HD (1080p) camera can. So it can capture more details of the object and the farther distance.
