What is the 4K HD monitoring system

In this era of high-definition video more and more sought after by the people, 4K came into being, 4K ultra-high-definition, the original technology used in television products, is gradually extending to the security field. A new security detonated the button for the security industry to develop a blue ocean. Then 4K surveillance camera is what? 4K surveillance video in the end how high-definition it?

4K VS 1080P HD monitor than high-definition monitoring equipment

4K common resolution 3840 * 2160 and 4096 * 2160 pixels in two specifications, in this standard CMOS progressive scan can reach 2160P. 4K high-definition webcam quality compared to 2 million pixels, vertical resolution higher, more precise level of detail of the screen, display clearer, more clean and delicate, but also gives the feeling of immersive, can effectively solve The need for high-definition picture quality and complexity of the monitoring requirements of light. It is understood that, 4K is called monitoring the field of ultra-high-definition monitoring equipment, the reason is 1080P is called HD or full HD, and 4K resolution is 1080P resolution resolution of 4 times. 4K magnified video images can still achieve 1080P image effects. Then the use of a 4K surveillance cameras can be used when the four 1080P HD surveillance camera?

4K surveillance camera images more high definition

From the security industry, 4k camera security industry to bring the most qualitative change is the image of more high-definition, more richer detail; higher resolution will always be eye-catching, people unable to stop; to create more customer needs, For security vendors means more market opportunities. 4K camera to the emergence of the security market to bring a new tipping point. For the security industry vendors who, of course, will not miss this huge market opportunity.

4K to the video surveillance system to bring new demands

For the 4K technology in the field of security in the use of the situation, the industry said that high-definition security industry is the general direction of the development of high-definition intelligent to provide a prerequisite for high-definition monitoring of the massive data storage and management of a higher Requirements. For the current mainstream high-definition webcam resolution of 1.3 million (720p) and 200 million (1080p), monitor the market up to 8 million hours resolution. The popular 4K 10 million pixel resolution, the capacity is too large, the use of existing H.264 algorithm is difficult to achieve the ideal bit rate compression, resulting in a series of related issues, such as ultra-high-definition large-capacity data transmission and storage problems . In order to solve this problem, H.265 came into being. H.265 is around the existing video coding standard H.264, to retain some of the original technology, while some of the related technologies to be improved. And the use of advanced technology to improve the code stream, coding quality, delay and complexity of the relationship between the algorithm to achieve optimal settings. Compared with H.264, H.265 improves compression efficiency, improves robustness and error recovery, reduces real-time latency, reduces channel acquisition time and random access delay, and reduces complexity. Because H.264 can only be lower than 1Mbps speed SD digital image transmission; and H.265 can achieve the use of 1 ~ 2Mbps transmission speed 720P (resolution 1280 * 720) ordinary high-definition audio and video transmission.

Conclusion:

Industry sources, although 4K monitoring product line is still in its infancy, but the combination of security and 4K technology is the inevitable trend of the development of security HD. 4K brings new technology and the ultimate visual experience, can capture more details. With the development of technology and user experience, will lead the security industry other 4K-related equipment and product development.
