1, IPC

In recent years, the application of the IPC + NVR in increase year by year and growing faster and faster, which shows that the market demand for the IPC and NVR. NVR and IPC development complement each other, will become a trend in the future.

NVR's development and the development of the front-end IPC is inseparable, the IPC mainly solve the problem of data acquisition, into a compressed code stream, through the network to back end equipment. NVR mainly to solve the storage in the transmit to stream, preview, playback, forwarding, etc. In recent years, due to the factors of market demand, many manufacturers are on the back end equipment research and development on the increased investment, up to now, many manufacturers can provide overall solution based on hd, many also applied to actual projects. And with the deepening of the IP is changed, the domestic brand of IPC have more opportunities, homebred brand IPC main technical indicators with the international brand gap is shrinking, and the cost advantage is significantly higher than international brands. We predict that the next 2-3 years domestic brands will gradually replace the imported brand.

With the development of hd IP cameras and the evolution of industrial chain, speed up promote the whole industry rapidly from traditional analog DVR matrix solution toward Gao Qinghua, IP solutions. During the reporting period, along with the trend of the IP video products, the company continues to increase r&d investment, strengthen and perfect the full range of IP products and solutions, promoted the rapid growth of IP video products of the company. Dahua company said in its annual report represented by SmartIPC intelligent solutions to promote the popularization and application of the video monitoring in the era of Internet of things.

2, information security technology

Although security vendor's security incidents happened in early 2015, with 2014 annual report appears to be no relationship, but the information security problem has been to the attention of the security industry. Annual report pointed out that although the company has invested resources to prevent information security risk under the environment of Internet application products, but still there may be a third party (including computer viruses, malware, hacker attacks and the like) deliberately try to damage the company's monitoring and control system/products, video monitoring storage or transmission information security problem. Though the company hasn't had any for attack or product/system accidents and significant adverse impact on the business situation, but there are still risks in the future. In 2015 as the country's emphasis on information security, security industry for information security technology products will emerge in endlessly.

3, 4 k

For the present, in the surveillance industry, 1080 p have yet to universal access, and higher levels of 4 k has become the hot topic of the industry, security monitoring, people pursuit of surveillance video resolution is always the clearer, the better, so monitoring picture can retain the more effective information and check the accuracy of forensics and the higher the 4 k is catered to the demand.

So how to meet this demand is 4 k? We know that the image is made up of each pixel, pixels per unit area, the more so the rich, its present image detail is picture can appear a little contrast in detail, on the contrary, the details of the images may show a chaotic sight, become the monitoring error, this is the definition of infinite pursuit, in addition, 4 k camera relative 1080 p camera, another advantage is that when both in the same definition, 4 k video camera's field of view Angle is four times that of 1080 p view Angle, that is to say, in places where need big scene monitoring, a 4 k camera will replace two or three cameras to achieve considerable performance, the stability of the whole monitoring project is of great help.

And, of course, the advantage of 4 k, but it to the system requirements for the whole project is also very high, the current mainstream coding techniques are still as h. 264, this kind of coding technology, 4 k demand for storage will be growing exponentially, relative to 1080 p in at present a lot of the monitoring project, storage occupied spending has reached more than 50, the increased cost of this will bring the user cannot bear the cost. Moreover on the transmission, the current 1080 p to achieve real-time monitoring effect, need 4 to 6 MBPS bandwidth, 4 k, at least need more than 10 MBPS can achieve real-time monitoring, in addition to the back-end equipment performance requirements are higher, such as display devices also need to reach the standard 4 k, in a word, if the monitoring project entire journey with 4 k, its cost will increase exponentially, which greatly restricted its wide application, but there is no doubt that in the security industry, 8 k 4 k or more is the inevitable development trend.
