The five development direction of the HD IP Camera

The five development direction of the HD IP Camera
As the core equipment in the network video surveillance system, application and popularization of the IP Camera represents the extent and stage of development of network video surveillance. Needless to say, the webcam is gradually adapting to the diverse needs of current and future, will become the mainstream of the field of video surveillance products, we're going to explore the future direction of the Network Camera's:
First, high-definition
HD basic term is accompanied by a high-definition television began, many years ago and became popular. Surveillance industry, however, truly large-scale application is the last year or two things, which is the rapid development of monitoring technology, including coding technology, network technology, transmission technology, storage technology, high-definition surveillance possible, the overall technical program mature gradually accepted by the user; Of course, the user to monitor the change in demand for HD promote also played a positive role.
Pudong District, Shanghai high-definition video coverage project is a typical representative. The project is the cut-off is currently the largest single high-definition video surveillance project, is currently the world's largest high-definition monitor the project. This project has more than a thousand monitoring large-scale high-definition technology to monitor the market's first truly large-scale high-definition monitoring project, played a positive role in promoting the development of high-definition, a milestone significance.
, Whether it is from the resolution, the display effect is still fluency of view compared with SD, HD than SD advantage. From the resolution point of view, the 720p resolution is CIF resolution 9 times 1080i/1080p resolution is CIF resolution 20 times, in the same display environment, the HD will be much clearer. Judging from the display, HD supports both large-screen display, but also supports 16:9 widescreen display can greatly enhance the user's viewing experience. From fluency of view, the high-definition support higher frame rates, such as 720p and 1080i/1080p can support the 60 frames / sec or 60 fields / sec image fluency twice as high than SD. Therefore, high-definition monitor is one of the most mainstream trend of the development of the surveillance industry, as the the HD trend of acquisition front-end, IP Cameras also moving along.
Standardized: ONVIF, PSIA, HDcctv
With the monitoring system from analog to digital, to move from the closed to the network, based on open standards to achieve interoperability between equipment, systems increasingly urgent demand. And in the Internet age, engaged in the construction of open standards, to provide users with the flexibility and scalability of the security system, security vendors competing for the local market, globalization has become a choice. Important as network monitoring, millions of high-definition Network Camera standardized the road has become a necessity.
Following ONVIF, PSIA have been established, the the HDcctv Union also set up, thus forming a network video surveillance market of the three standards. The establishment of these organizations, we hope to promote the realization of the vision of a unified standard monitoring in the Internet age. ONVIF, hope to promote the application of network video in the security market through a global open interface standard, this interface standard for network video products from different manufacturers will ensure interoperability. PSIA Physical Security Interoperability Alliance was established in August 2008, the goal is the creation of a standardized interface for the physical security system hardware and software platforms, different security systems based on IP network compatibility. HDcctv Alliance (HDcctv Alliance) mainly by chip manufacturers and system suppliers to set up, mainly for high-quality monitoring system (High Definition Surveillance Systems) developed a new standard to look through the new standards, development easy to build, lower cost network solution
Three intelligence
Overall, the the simple intelligent analysis including motion detection, alarm block (these functions have been widely used).
More complex intelligent analysis including behavior recognition and analysis, such as face recognition, packet loss, and alert. Intelligent analysis of the last few years has been very "hot", many manufacturers in a variety of exhibition urgent launched related products, including a variety of intelligent analysis capabilities of the IP Camera. However, due to the actual use of the environment is complex, combined with the algorithm itself is not very mature, and adaptability is not strong, resulting in false alarm lot. On the other hand, high customer expectations, but the poor performance of intelligent products in actual use, is often difficult to meet the actual needs of customers, and high maintenance costs, and often makes these devices become a kind of decoration.
There is no doubt, however, intelligence is an inevitable trend, with the increase in the number of monitoring, Imagine dozens, hundreds or even thousands of channels of video, rely on the human eye 24 hours a day staring at, unrealistic and can not. How to quickly extract useful information from the vast amounts of data, for the user, which is very effective, but also customers eager to solve, which will also be one of the now and future Network Camera products in the market to compete.
Megapixel HD IP Camera can provide more key details, which can make intelligent video-based analysis for greater accuracy, and greatly enhance the level of intelligence applications. Its rapid growth in some market segments, such as the transportation sector, the development and application of intelligent products is relatively mature, such as road conditions, vehicle statistics, license plate recognition, retrograde, press the yellow line, parking violation, including the monitoring of traffic conditions , as well as the capture of the offenses, has been widely used
Fourth, the infrared
HD IP Camera with respect to the ordinary camera light-sensitive chip, the same pixel size into multiple increases, it is caused by a corresponding reduction in the multiple sensitive point size, under the same exposure conditions, high-definition IP Camera relative to the the ordinary pixel camera low light performance will be much worse. This means that if the high-definition camera night infrared light intensity of the demand is much higher than the ordinary pixel infrared camera. For example, a 1.3-megapixel 1/3 "HD CCD size, ordinary CCD with 430,000 pixels (480 lines) 1/3" size, high-definition CCD pixels per unit area is three times that of ordinary CCD, HD CCD pixel photographic performance as compared to the ordinary CCD sensitivity 1/3, which is the effect of HD camcorder night root causes of poor. The practice now is to extend the exposure time, to make up for the deficiencies of low light performance is not good, but would have resulted in image prone to smear phenomenon. If high-definition night image effect is good, can only increase the ambient illumination to supplement this deficiency.
HD camcorder for HD fill light, infrared light at different distances monitoring program configuration. Close selection of a wide angle of the LED lamp board to fill light, and can achieve a wide-angle monitoring, and low cost, in the distance due to the required fill light intensity is relatively large, the angle is small, the use of ordinary LED is difficult to achieve the desired effect. Therefore, in the distance selection directive, the energy is concentrated laser infrared light to fill light.
Fifth, ease of use
Unlike traditional analog cameras, Megapixel HD IP Camera comes to the areas of IT, IP Cameras and analog cameras in use on a large difference, especially for the operation and use of personnel have higher requirements. For most of the domestic contractors, integrators and users, they are very familiar with the traditional CCTV systems, Network Camera is still in the early stages, so the IP Camera on the development and design to take into account the characteristics of these people, must be fully reflected in the ease of installation and ease of use, such as in PoE support local video output, as well as convenient local debugging, wireless-enabled.
