Tomsk Polytechnic University has put their computer engineers to work to create an algorithm for surveillance cameras that will detect a face in a crowd of people in high resolution. Allegedly, the algorithm would be able to calculate the number of people in the frame, the gender and age of the people being filmed.
Ilya Kalinovskii, the developer of the algorithm and a Ph.D. student in the Department of Computer Engineering at TPU, said, "In order to detect a person on his face image in the crowd, like on stadium or in subway it is required to work with an image in scene with very high detail. 4K resolution is suitable for this purpose. Because of the large amounts of data, it is difficult to even store these videos not only to process them, not to mention intellectual analysis."
CCTV is being revolutionized by the 4K, ULTRA HD movement which has equalled better quality video which is better for businesses that would need to identify criminals and see all of the details. Monitors cost less as well which makes buying a UHD CCTV setup is becoming inexpensive. However, there is a problem of exporting the video to other sources due to the sizes of the recorded video. Advanced data storage will also need to be factored in for businesses who opt in for a 4K solution.
Security Electronics and Networks speaks about the technical part of it, saying that running a UHD setup has more to it than meets the eye:
If the sensors are large enough, the lenses are good enough, the light levels high enough, the network is capable enough and the storage sufficient, then Ultra HD cameras will give end users a lot more detail than 3MP 1080p cameras can. But this capability has to be balanced against many things. Image quality is about more than megapixel count.
Vlado Damjanovski, an employee of ViDi Labs when asked whether 4K is the next CCTV standard, he said, "My answer is yes and no. 4K is a known development in broadcast TV but CCTV is only a little sister of broadcast technology, and eventually follows its trends. But unless the technology trend is developed by the larger broadcast industry, its very unlikely CCTV will develop a whole new standard on its own. So yes, it is the next big thing, but not so big as some may want to think."
However, according to IFSEC Global, who focus on companies that utilize factories with production lines and anything in the industrial sector say that 4K could be useful in manufacturing plants. They say:
The number of pixels across the image required to cover the production line is 5,120. So in order to cover that area with HD cameras (delivering 1920 X 1080 pixels), you would need three cameras.
However, if you instead specified the use of Ultra HD 4K cameras (delivering 3840 X 2160 pixels) like the new Sony VM772R, you would be able to cover the whole production line and associated components with just two cameras
They also say it would help with accident claims from employees and would be able to cover both the employee and the business sufficiently. The case for 4K surveillance is becoming more apparent in the world of production line factories.
However, a report released this year named 'The top surveillance trends for 2016' by IHS (a company that generates statistics and provides information from surveys) says that 4K has not yet convinced anyone in surveillance industries. They say, of the "66 million network cameras predicted to ship globally" this year, only one percent of the sales will be Ultra HD devices.
It is estimated that Ultra HD will only be further into becoming the next standard of CCTV in 2018. Until then, if you have the hardware and data storage space for 4K surveillance, it could help you in identifying something that could save your business and its assets.
