China's monitoring market development monitoring market In the development process, networked monitoring began at the time when it was not a scent, mainly because the technical advantages of networked monitoring were not as obvious as those of the analog products passed. To use networked video surveillance to win the market, we must vigorously develop high-definition technology and solve the problem of constraining its development. In recent years, due to the improvement of the technical reserves and network facilities of ip cameras, the high definition of network cameras has been significantly improved.
The future technology trends of HD network cameras 1, coms gradually replace ccd
The cmos sensor responds faster than the ccd, and the performance of the cmos sensor is rapidly increasing. Therefore, it is more suitable for large data volume features of high-definition monitoring.
2. Increasing resolution The resolution of the network camera on the market is 1.3 million pixels, 2 million pixels, 3 million pixels to 5 million pixels, 8 million pixels, and even products like 10 million pixels are beginning to emerge. So people's demand for resolution is getting higher and higher.
3. Standardization Either onvif or psia is the standard for the formation of spontaneous organizations. In the next few years, standardization will become the passport for HD network cameras to reach the market.
4, isp is encoded by the chip integration through the integrated isp, not only can significantly reduce system costs, but also greatly enhance the stability of the video, optimize the optical performance of the image. This has an important role to play in improving the imaging quality of HD network cameras.
5. Smart analysis function is more practical The intelligent analysis functions that have been implemented or are currently being implemented in HD network cameras include: video occlusion and video loss detection, video change detection, video blur detection, video motion detection, and entrance and exit statistics , crowd movement and congestion recognition, item legacy identification, intrusion recognition, etc. These functions seem to be "less" than the previous smart analysis functions, but they are more practical.
Intelligent high-definition video camera problems encountered in the development of <br> <br> Today, our intelligent HD network cameras is now in the early stages of development, the following issues at this stage smart HD camera encountered in the development, to analyze.
Question one: The application and popularization of intelligent high-definition video cameras in the product series and accessories are related to the complete series of cameras and supporting facilities. In order to meet the needs of different projects, a full range of digital cameras with various features and varieties must be mastered. The key technologies are auto exposure, auto white balance, auto focus.
The intelligent HD monitoring backend devices pdvr (or nvr), hybrid dvr, etc. are much higher than the traditional thresholds of traditional dvr technology, requiring higher VGA output resolution and higher decoding and processing performance, and the hardware structure is also higher than the traditional dvr. A lot of complexity, so only a small part of the dvr manufacturers can successfully make intelligent high-definition back-end recording equipment.
Question 2: In terms of price and price, some domestic companies have mastered the core technology of digital high-definition cameras and made local digital HD cameras. The price is cheaper than the previous purchase of foreign agents. At present, the price of high-definition cameras is increasingly approaching traditional analog cameras, so that more users can use smart HD.
Some high-end intelligent high-definition surveillance projects usually require a video wall. The intelligent high-definition wall is not a matrix or a traditional decoding card and decoding box, but requires intelligent high-definition dedicated wall decoding equipment. Because the resolution of current high-definition LCD monitors is generally as high as 1080p, there is an urgent need for video display front-ends and recording equipment to match them. Only in this way can the HD monitor achieve its best value. Otherwise, it will use the traditional d1. LCD monitor HD effects. In terms of the lens, the optional space for the smart HD camera is too small and the price is expensive, which also affects the rapid popularity of smart HD.
The country is vigorously promoting the application and development of the Internet of Things technology. Its basic idea is to "connect objects and sense China", that is, "a more comprehensive and thorough perception, more comprehensive interconnection, and more intelligent decision-making." Video and HD network cameras that connect it directly to the Internet will surely play an even greater role in the application of the Internet of Things and the next generation of the Internet.
Optional camera Puzzles <br> <br> For us, what is best for our products? Can the current HD webcam be as clear as possible? Below, we will help you solve the confusion when choosing high-definition webcams through the following discussion.
1. Clarity or not, practicality is the most important When we choose a high-definition camera, clarifying our own needs is the most important preparation. At present, the average video camera already has a very high imaging capability. Therefore, unless you need very special monitoring capabilities (such as intelligent transportation, financial institutions and other fields), an ordinary high-definition network camera is sufficient to meet the daily needs of security monitoring work. Excessive imaging configuration not only causes waste, but also does not bring more convenience to the monitoring work.
2, image quality, in many ways to consider the performance of high-definition cameras, certainly still have to judge from the picture quality. If you are sure you need a high-definition camera to meet your work needs. Then in the selection process, you need to pay attention to the clarity (moving, static), color reproduction, etc. of the camera under different conditions. There is also the ability to maintain the same clarity and stability in the picture quality when shooting different objects. Horizontal definition is only one of the major reference aspects for the imaging quality of a surveillance camera. Wide dynamics, automatic white balance, digital noise reduction, automatic metering compensation, etc. all have a profound effect on the imaging quality of security cameras. Whether the transition in the bright and dark transition area is natural, whether the wide dynamics can be automatically adjusted, whether the detail observation effect under low illumination is clear, and the degree of influence of noise and so on. To a large extent, they all reflect the level of high-definition cameras.
3, high-definition effects, multi-factor casting, the overall solution is the most important In fact, high-definition camera work in addition to the complexity of the machine itself, high-tech investment, supporting ancillary facilities is also an important reference image quality is good or bad. For example, whether the monitoring camera's adjustment mode is perfect, whether the menu function is rich, and the lens selection during the installation and debugging process, will determine the clear quality of the picture to a large extent. In addition, whether the transmission line of the signal satisfies the transmission requirements of the high-definition camera, and whether the compression and decompression of the terminal transmission device can be completed with high quality also affects the work quality of the high-definition camera.
Therefore, the realization of high-definition surveillance can not only be accomplished by a simple high-definition network camera itself, but it can be achieved by a combination of security cameras, surrounding environment, and supporting equipment. Therefore, before selecting high-definition cameras, in addition to monitoring the camera itself, there will be more attention to the environment, I am afraid you will gain more than expected.
The significance of installing security monitoring 1. Security monitoring no longer makes good people "injured"
In the face of social crowds, the events are numerous and complicated. There are no sounds of silence, security monitoring is recording the events that occur at any time, and whether you are Gao Fushuai, Bai Fumei, or silk are without exception. Last year, the shocking events of Xiaoyue Yue passed through the rumors and made people known. Xiaoyueyue was crushed by two cars in the Huangpu Guangfo Hardware City in Nanhai, Foshan. Within 7 minutes, 18 passersby passed by but were blind but indifferent. On the way, the last scavenger, Auntie Chen Xianmei, came up with a helping hand, and Aunt’s good intentions attracted a lot of controversy. The insensitivity of 18 passers-by was recorded under the surveillance camera, which proved that the act of A-yi was a kind of “good intention†with responsibility. This is not controversial.
2, video surveillance so that the food of leather shoes goods "see light dead"
The issue of food safety has always been the focus of social concern. In the first half of this year, various food safety issues such as waste oil, poison jelly, poison capsules, and old yoghurt were successively exposed by the media. Food safety has once again become a hot topic for people to talk about. In June of this year, Yantai Apple's drug kit incident caused widespread consumer unease about Shandong Red Fuji. Let people have to look at how many other foods around them are the ones that we do not know.
To prevent "sickness from the mouth," we must "grab the core and grasp the fundamentals" to prevent food problems from the source. During the food production process, the food factory establishes a video surveillance system that monitors every step of food production and strictly controls each step.
3, high-definition monitoring to build a harmonious society of high-definition monitoring Compared with the traditional monitoring, its picture quality is more clear, a wider range of radiation. In recent years, with the high-volume application and popularization of high-definition surveillance projects and projects in safe cities and road monitoring areas around the world, there have been numerous reports of police cracking down on crimes through high-definition surveillance and arresting criminals.
Record the truth, trace the source, punish evil and promote good. It is undeniable that security monitoring has entered our lives and we are affected. With the increasing popularity and promotion of high-definition surveillance products, it is believed that HD surveillance will create a safer and better life for people. China will soon enter a harmonious society.
