The future development of high-definition surveillance will be combined with intelligence

One, HD still lacks

Through the continuous development of the monitoring industry in recent years, there are more and more industries and the number of monitoring applications. However, in the course of use, it sometimes happened that: After the case occurred, the policeman rushed to the scene and read the video. It was found that at the time of the incident, the characters on the surveillance screen were blurred, and the images had a lot of snow and noise.

From the perspective of the user, the content recorded by the conventional SD monitoring system is difficult to provide or satisfy the user's requirement for monitoring the details of the content, which limits the level and effectiveness of the monitoring application. Therefore, it is hoped that a new technology will break this restriction. From the product's technical point of view, standard definition product technology has no more room for development. From a market perspective, the market needs a new product to stimulate the growth of the industry and the market. The HD network camera exactly meets the needs of many parties and becomes the current and future development direction. In the bustling city monitoring, the facial features of pedestrians can be clearly seen; in the bank's counter monitoring, the details of banknote counting can be clearly seen.

Second, what problems need to be solved

With the development of China's computer network technology and the continuous improvement of infrastructure construction, the convenience brought by the Internet has begun to change our lives. The rapid development of network facilities has laid a solid foundation for high-definition network cameras. High-definition monitoring systems need to meet the flexibility of the deployment system and distribution responsibilities of managers; users need to be able to use surveillance videos in the fastest and most convenient manner; and the continuous expansion and construction of the systems must be met. HD network cameras can fully meet the needs of these applications through integration with computer network systems. Due to the access characteristics of the IP network, administrators can flexibly deploy storage locations for surveillance videos and clarify related management responsibilities. Through the interconnection characteristics of IP networks, users can request monitoring or video recording through various computer network terminals such as PCs and mobile phones. Due to the topological characteristics of IP networks, the system can meet the needs of continuous expansion. Therefore, HD network cameras will be the main product type of HD cameras.

1, monitor picture clarity problem

The first thing that HD network cameras have to solve is to monitor picture sharpness. High-definition network cameras generally use a sensor with more than 1 million pixels for image acquisition. Taking the current mainstream 720P HD network camera as an example, in the equivalent scene, the resolution of the monitor picture is improved by at least 8 times over the CIF resolution, which is more than D1 resolution. Increase at least 2 times.

2, anti-interference issues

High-definition network cameras then solve the anti-jamming problem. Because the HD network cameras use all-digital systems for acquisition and transmission, their anti-interference performance is extremely strong. Responsive to the monitoring image is no snow-like noise, image overlap, etc., making the monitoring image always clean and clear.

Third, the future development of high-definition and smart integration

The cost of HD network cameras is still a major factor hindering the rapid development of its market. According to the survey, in 2011, network cameras generally reduced their prices by about 10% compared with 2010, with HD surveillance cameras falling by about 25%. However, as the supply of high-definition network cameras increases, the prices of core devices such as CCDs and CMOSs ​​will drop, and the overall price will further decline.

HD network cameras will be combined with more industrial applications. In the future, seamless integration of industry business information and high-definition network cameras can be realized, thereby providing users with higher system performance. For example, high-definition webcams use image recognition to notify their business units of real-time information in order to act as a quick warning.

HD network cameras will be better integrated in the Internet technology, can provide multiple users with a variety of different ways of real-time image stream. HD IP cameras can also send alarm messages and images through tools such as E-MAIL and MMS. It can also communicate with terminals through Internet communication tools such as Weibo and QQ, such as real-time video broadcasts.

HD network cameras can load a variety of applications according to the needs of users, because HD network cameras are embedded devices with operating systems. A variety of different applications can be downloaded by the administrator to the HD webcam just like our smart phone downloads the application. This can make the application of high-definition network cameras more in line with the needs of users.

The combination of high-definition network cameras and intelligent functions, megapixel HD network cameras provide a good environment for the implementation of intelligent algorithms. Intelligent algorithms can do some identifying applications based on high definition original images. For example: perimeter warning, stolen goods, legacy of dangerous goods, traffic statistics, flame detection, face recognition, license plate recognition, etc., to meet the needs of customers in different industries.

Conclusion

With the increasing demand for high-definition applications in the security industry, the HD network camera market is in a period of rapid growth. Although it is plagued by various factors such as system cost, ancillary equipment, and application performance, with the continuous development of high-definition network camera technology Development, HD network cameras will become the main force of the future high-definition surveillance market. Its market demand is also experiencing an unprecedented diversification of the monitoring industry. It is believed that with the continuous progress and breakthrough of technology, HD network cameras will exhibit more intelligent, easy-to-use and diversified product features.

About HD Network Cameras:

High-definition megapixel network camera is a professional video surveillance camera applied in the surveillance field in the security industry. MPEG4 encoding algorithm is usually used, and high-end standard h is used. The 264 algorithm has a video resolution of 720P (1280*720) or 1080P (1920*1080). Based on standard H. The megapixel network camera of the 264 MainProfile algorithm generally uses a 5 megapixel progressive scan image sensor and supports high-definition analog output. The definition can reach 720TVL broadcast-quality image quality. Due to the use of standard H. 264 compression, video files can be decoded using a standard decoder, supports common playback software to play directly. At the same code rate, it has an image quality that is more than MPEG-4. Under the same picture quality, the code rate is only one half of that of MPEG-4. Because the high-definition megapixel network camera is not only high-definition, but also easy to operate and easy to install, it will greatly reduce the cost of engineering wiring and construction, allowing your CCTV network to be infinitely extended.
