1, IPC (IP Camera)

In recent years, IPC + NVR applications is increasing every year and growing faster and faster, it also shows a greater demand for IPC and NVR's. NVR and IPC's development are mutually reinforcing, it will become a trend in the future.

IPC development of front-end development and NVR are inseparable, IPC mainly to solve the problem of data acquisition, converted into a compressed video stream transmitted over the network to the back-end equipment. NVR mainly to solve the transmission of video streams over the store, preview, playback, forward and so on. In recent years, due to strong market demand factors, many Chinese manufacturers are on the back-end security equipment increased investment in research and development, up to now, a lot of Chinese security manufacturers can provide high-definition based on the overall solution, many also applied to the actual project. And with the deepening of IP-based, Chinese brands have gained more opportunities IPC, IPC main technical indicators Chinese brands and international brands gap shrinking, and the cost advantage significantly higher than international brands. We predict that the next 2--3 years Chinese brands will gradually replace imported brands.

Hikvision noted in the 2014 Annual Report with the HD IP camera development and maturity of the industry chain, accelerate quickly toward industry-wide high-definition DVR plus from traditional analog matrix scheme, IP-based solutions that direction. During the reporting period, with the trend of IP video products, the company continued to increase investment in research, strengthen and improve the full range of IP products and solutions, IP video products to promote the company's rapid growth. UOB shares annual report noted that the company Smart IPC as the representative of the intelligent video surveillance solutions to promote the popularization and application of the Internet of Things era.

2, Information security technology

Although security vendors of security incidents in early 2015, and 2014 Annual seemingly nothing to do, but the information security industry security problems have attracted attention. Hikvision in the 2014 annual report presented especially information security risks. Annual report noted that while the company has invested resources to prevent product information security risks in the Internet application environment, there may yet be a third party (including computer viruses, malware, hacker attacks and other similar cases) deliberately try to damage the company's systems / product cause security problems of storing or transmitting information. While in the past the company has not encountered any attack or due to product / system accidents have a significant adverse effect on the business, but the future is still at risk. In 2015, with the Chinese government attaches great importance to information security, the security industry technology for information security products will also be endless.

3,4K

For now, in the surveillance industry, 1080P also has not been universal, and higher levels of 4K has become a hot topic in the industry, security monitoring, people will always pursue surveillance video resolution, the sharper the better it is, Such information can effectively monitor screen will be more reserved, consult the higher the accuracy of forensics, 4K (4096 × 2160 or 3840 × 2160) is to meet this demand.

So 4K is how to cater to this demand? We know that the images are one pixel is composed of dots, the more pixels per unit area, then the rendered image picture detail will be more abundant, the picture of a little bit of detail Jieneng contrast presentation, on the contrary, it details the screen may exhibit a chaotic scene, be monitoring the misunderstanding, that's what people endless pursuit of clarity the reason why, in addition, 4K camcorder 1080P camera and a relative advantage, that is When both at the same resolution, viewing angle 4K camera 1080P four times the viewing angle, which means that some of the need to monitor large scene where a 4K camera will replace 2-3 cameras to achieve considerable The performance, which is monitoring the stability of the whole project is very helpful in.

Of course, 4K is a lot of advantages, but the system requires it to the whole project is also quite high, the current mainstream coding technology is still as H.264 (H.265 not yet mature), under such a coding technique, 4K of storage requirements 1080P relative terms will grow exponentially, and in many of the current monitoring project expenditure store has occupied more than 50%, the cost increases will bring heavy users can not afford the cost. Furthermore, the transmission, the current 1080P to achieve real-time monitoring results, it needs 4-6Mbps bandwidth, 4k you at least need more than 10Mbps in order to achieve real-time monitoring, in addition to the back-end equipment performance requirements also higher, such as the display device 4k standards also need to reach, in a word, if the monitoring project full use of 4k then its cost will become exponential growth, which greatly restricts its widely used, but there is no doubt that the security industry, 4K even higher 8k (7680 × 4320) is the inevitable trend of development.

British fly Billiton Annual Report 2014 the company completed the middle 4K HD smart fixed cameras, the integration of the ultra-high definition and development of intelligent features, including high-definition 4K intelligent fixed cameras and 180-degree panoramic camera to the leading domestic level. Hikvision also repeatedly raised in the annual report the company developed a variety of products in the integration of 4K technology.

4, Low Illumination (Star-class products)

In many trends in the security industry, low-light surveillance technology is also an inevitable trend, after all, the security industry is the sale of security, and over ninety percent of all crimes occur at night or in poor light, if abandoned to monitor the night, why achievements of its security? Therefore, low-light cameras usually used at night or in poor light the scene in order to protect people's lives and property.

Low-light camera and ordinary camera principle is the same, the biggest difference is that the monitoring of the performance of low-light, now without the need for additional lighting equipment, the effective monitoring of illuminance reaches 0.001Lux and below, is often referred to the Star-class camera, this is the best low-light cameras a class.

Low-light surveillance technology are currently at the expense of color based on the display screen in the form of black and white in order to achieve a more low-light monitoring needs, while the use of infrared or laser light, especially, and to achieve a color monitor, it can only use white to light, and radiation from the white and applications are limited, and it can also cause light pollution, to bring adverse effects.

For now, the illumination effect 2 million pixel camera has been more mature, to meet the basic needs of 24-hour surveillance, along with the evolving definition of continuous improvement and illumination control technology, the future monitoring in complete darkness of fear Meanwhile, also in a more clear picture to please your eye.

5, Intelligent Analysis

With the improvement of technology, the development of video analysis and computer processing power, IVS, namely intelligent analysis system gradually become a hot topic. Now, IVS common application recognition and license plate recognition.

IVS to improve the efficiency of the security system has played a significant role in a particular scene now IVS applications mainly in the peaceful city road monitoring, detention centers, prisons, museums, warehouses, factories, subway stations, and in the civil, commercial surveillance has not been effective promotion.

IVS biggest advantage is that you can replace a portion of repetitive manual labor, improve the efficiency of video surveillance from the previous passive when dealing into the present initiative, prior defense. IVS can be real-time detection and dealing with emergencies, such as accidents or illegal invasion; publish video content in real time of important events, providing image analysis and statistical reports for policy makers, in order to strengthen the foundation for decision-making; open architecture can support the industry Signal flow standard format, structured data, analog / digital, intelligent analysis can push video content to different channels and mobile devices. IVS These advantages make it will be hot in 2015.

In addition, IVS technology also has its drawbacks: the accuracy of IVS judge can not reach one hundred percent accuracy rate zone detection and generally over the line detection is about 95%, especially at night if the light is too dark, the noise rise, when the image clarity derogation and other external factors will lead to its accuracy rate. Over time, advances in science and technology will be increasingly, video analysis capabilities will become increasingly powerful, the accuracy rate will also be improved, the application of intelligent judgment behavior will correspondingly increase, the future will be more effective IVS replace human, to be more widely used.
