Looking back on the past year, the Chinese economy has entered a new normal development stage, and the video surveillance industry has undergone tremendous changes. How to deal with the new normal, the author personally believes that continuous innovation is the source of the rapid growth of enterprises in the new economic normal. The basic path of innovation is market driving and technology promotion, and technology is ultimately to promote market development, tap potential demand, and better meet market demand. So what is the market demand?
The development of the video surveillance industry is usually followed by the development of the electronic consumer market. Now, the 4K Ultra HD TV in the mall is full of people's attention. When 4K Ultra HD TV was chased by the public, I wonder if everyone is aware of the subtext that this behavior reflects. Looking back at our mobile phone, from iPhone4 to iPhone6, the resolution of mobile phones continues to increase. People have never stopped on the road of chasing HD, HD, or even HD. It is foreseeable that one of the needs of video surveillance is endless HD. Based on this concept, 4K HD surveillance is bound to make a big difference.
So, what exactly is 4K? What kind of development prospects will 4K have in security?
4K, security new target
The so-called 4K, in simple terms, is 8 million pixels, which is equivalent to 4 1080P. At present, the common 4K resolution is 3840&TImes; 2160 and 4096 & TImes; 2160 pixels.
Since the first year of HD, the strong development of HD has been a leaps and bounds. At present, the domestic high-definition mainstream resolution is basically concentrated on 720P and 1080P. Many companies may find it sufficient to use the current HD in the security industry, but it is not. Now 1080P can solve some problems in some scenarios, but in some big scenarios, it can't solve the problem. It must be solved by higher resolution such as 4K we said. In terms of functionality, some scene users have such needs, such as ultra-wide monitoring, safe city high point monitoring.
4K can bring users higher definition and more details. In some key monitoring areas, we often see a number of cameras on a pole on the road. This is often caused by different business units' different concerns in the same scenario. If you use 4K cameras, through multi-stage amplification, each business department can see their respective areas of interest, which can save investment costs and achieve information sharing.
However, if 4K is simply defined as the improvement of sharpness and image detail, I am afraid it is not accurate enough. In GB 50348-2004 "Safety and Prevention Engineering Technical Specifications", the safety precaution system has been defined, which clearly states that "the safety precaution system is aimed at maintaining social public safety." As the most basic needs of people, the improvement of clarity does provide more reliable data for after-the-fact forensics, investigation and analysis, but the way to deal with it afterwards is a bit of a remedy. We hope that we can find problems early and kill the safety hazards in the cradle. In Hikvision, 4K should be smart HD, smart HD and smart HD. We pay more attention to the technical support behind 4K. Therefore, 4K is our goal, but not the purpose, "understand" is our ultimate goal.
So, who will solve the problem of "understand"?
Smart 2.0, new height of intelligence
Speaking of this, perhaps everyone has some answers in mind. Yes, it is intelligent analysis technology - the second demand point of video surveillance, but also an important technical support behind 4K.
In the past two years, due to the improvement of intelligent algorithms and the enhancement of chip processing capabilities, smart products have developed rapidly and their maturity has been rising. A series of "smart front-end" IPC products represented by Smart IPC have brought intelligence into the practical stage. However, Smart IPC is only a single product, and it can't solve all the problems of users. Especially in the era of big data, the number of video points is growing rapidly, and the search efficiency of massive video faces serious challenges. Therefore, intelligent analysis should be the whole system thing.
Through one year's accumulation, Hikvision has deepened on the basis of Smart IPC, extending from a single product to a product line such as Smart dome, Smart NVR, and Smart platform software, and these Smart products form a complete " Smart 2.0 Smart System." Through the layers of the Internet of Things, such as Zhibu, Zhifang, Zhishen, and Zhirong, the system not only implements intelligent analysis at the front end, but also supports intelligent functions in the back-end storage and system platforms. Level" monitoring problem. The Smart 2.0 smart system can now implement 17 intelligent analysis functions including 10 behavior analysis, 4 abnormality detection, 2 feature recognition (license plate recognition, face recognition) and 1 statistical analysis to effectively improve the whole system. operating efficiency.
The Smart 2.0 smart system is a system with "thought" based on the in-depth analysis of user needs and the characteristics of user business applications. It has the ability to "understand".
Although Smart 2.0 solves the problem of “understandableâ€, there is still a problem in the promotion process of 4K that cannot be underestimated. At present, the H.264 encoding algorithm is mostly used for 4K images. Taking Hikvision as an example, about 12 Mbps code stream is required under this encoding algorithm. Bandwidth and storage are also the cost of HD system construction, and the user's investment will rise linearly, which will affect the promotion of HD. It can be seen that in the promotion process of 4K, the first problem to be solved is the bandwidth and storage problem.
To solve the bandwidth and storage problems, we have to start from the source.
H.265, behind the scenes of high-definition popularity
As we all know, H.264 is the mainstream compression standard in the current video surveillance field, and H.265 is the new video compression standard developed by ITU-T VCEG following H.264. As a new generation of video compression technology, the most obvious feature of H.265 is that the compression performance is doubled compared to the current video compression technology H.264.
At the same time, in the face of the impact of the mobile Internet, the user form of the security market has quietly changed, and the demand for civilian security is growing. Internet-based security products also extend from professional applications to consumer products. In the information age, people like and prefer instant messaging tools, so real-time will become an important factor when this transition occurs. In other words, civil security will increasingly involve wireless network transmission technologies, especially 3G/4G mobile networks. H.265's high compression ratio features better network adaptability to meet the needs of high-definition surveillance in different bandwidth environments. Therefore, H.265 will further promote the popularization of high-definition and even ultra-high-definition video transmission under mobile networks.
It is foreseeable that H.265 is bound to greatly advance the process of high-definition popularization.
Conclusion
Overall, HD and intelligence are in line with market demand and are the general direction of future development. As far as the current landing situation is concerned, although the 4K accessory products have been launched, but due to bandwidth and storage pressure, it is only applicable to some key monitoring areas for the time being. It will take some time to fully roll out. As another important practice of intelligent landing, the Smart 2.0 smart system has received extensive attention once it was launched. We believe that following Smart IPC, Smart 2.0 will trigger another wave of intelligence. H.265 has just been launched, and some domestic manufacturers have followed the launch of the front-end products. Hikvision has launched and improved the corresponding products from front-end acquisition to transmission to storage. Hikvision believes that the market may quickly revolve around H.265 in the next one to two years.
Looking forward to the future, with the further maturity of technology, it is believed that 4K, Smart 2.0 and H.265 will gradually merge and greatly promote the rapid development of the security industry.
