Intelligent speed dome camera increasing and progress day by day

2014-06-13

As an important part of the network high-definition front-end acquisition system, the intelligent speed dome camera is a perfect integrate between the traditional analog intelligent speed dome camera and the network HD advantages.With the rapid development of high-definition, intelligent, network and other technology, the features of the network high-definition speed dome camera are constantly updated. Under the intelligent tide, the development of intelligent dome camera face more and more difficults, the security improvement need constantly efforts of skills.


Dome camera localization push the market of surveillance.


The HD speed dome camera is same as HD video camera, it's development far excceed the expectation of the market. The main reasons have two: 1. the HD technology become more sophisticated. Using new generation of high-definition CMOS sensors and high-performance of encode chips, makes great progress in the picture quality and picture fluency of the IP HD speed dome camera, some manufacturers who are hesitate on HD speed dome camera before now constantly participated the HD speed dome camera market; 2. The decreasing cost of HD chips and dome cameras.


These two reasons push the rapid growth of HD dome camera market, expecailly the low cost plan of the HD dome camera are invading the market of traditional analog dome camera. Faced with the  cost-effectiveness common requirement of domestic market, the low cost of dome camera will inevitably bring shock to the market, and will increase the demand accordingly. In corresponding, the intense demand for high-definition surveillance will promote to decrease the cost in application. Speaking of the sistuation of high-definition speed dome camera, Hikvision's engineer Li Yiyuan said: Follow the rapid development of networked, high-definition and intelligent, HD speed dome camera have been used in safe cities and other projects, and the market share increase obviously. Faced with the infinite need of market, on the one hand, all manufacturers actively accelerate the promotion of high-speed dome camera network, high-definition, intelligent skills, constantly launched higher quality HD speed dome camera; on the other hand, manufacturers are paying more attention to independent intellectual property rights, promote the localization of the key components of the HD speed dome camera and the central drawing processing skills, then promote the high-speed camera products of their apperance and performance to catch up with the international brands.


At that time, although the center's CMOS sensors and chips are still controlled by foreign manufacturers, but the trend of localization of HD camera is very significant. For example: Hikvision, Dahua, Advanced, safer, wapa and other big manufacturers produced AIO chips and get good reputation from market, comparing with Hitachi, Sony's HD chips although there is a few shortcomings, but the difference is gradually decreasing. In the future, HD chips filled with the entire HD dome camera market maybe will come from domestic manufacturers.


Intelligent skills promote surveillance


When talk about the "smart" question of security surveillance, of course not to neglect the skills of intelligent video analysis. A few years ago, intelligent video analysis skills were proposed, followed by the rise of high-definition video surveillance, providing more space for its use. At that time, intelligent video analysis skills such as active policy stalking, motion detection, cross-line alarm, and personnel calculations have been widely used.


The intelligent skills of HD high-speed dome camera are different from intelligent video analysis skills, and its application is more extensive. Thanks to the continuous improvement of chip computing capabilities and the intelligent algorithms, intelligent skills are valued on HD speed dome camera. Besides the above-mentioned intelligent video analysis techniques, they also present, alarm linkage, punctual cruise, smart cruise, 3D manipulation, temperature monitoring and other intelligent skills.


At that time, many HD dome camera manufacturers had made achievements in the intelligent skills, and the products they launched were professionally recognized. Among them, the most representative is Kedacom's gun-dome camera linkage active stalking system, and it is the best in terms of speed, clarity, agility and accuracy. Hikvision's DS-2DF7286-A new generation high-definition speed dome camera uses 1/3" CMOS picture sensor and high-performance chips, the function is secure and stable, and it can using on intelligent motion-spotging, video surveillance is more flexible and effective; it also incorporates the function of translucent and SmartIR, which enables clear pictures and avoids near-infrared over-exposure in the haze climate. Liuhe Weiye's latest S3 series high-definition speed dome camera products support high-definition video intelligent analysis and full initiative stalking, these functions in the use of internship scenarios to bring more efficient use of the method to the user, no longer need many protection personnel to "stare" the picture.


Intelligent speed dome camera develop skills of viewpoint never stop


How to see more clearly in the night vision environment


As you know the video surveillance sistuation, the current equipment on the HD monitoring in daytime environment has ruled out all the problems, whether it is in foggy or a dazzling sunny day, can not really perform the surveillance equipment. But the night vision monitoring environment is still a difficult problem for many devices.


In many devices that I have test, although the device perform good at high-definition appearance in daytime but can not process well of the noisy in weak light. Because need to see farther objects in an environment where is no light, therefore, there is some of the light-filling skills inside the equipment still have a lot of noisy manufacturers can not handle, that will much influence the video surveillance. And if the noise problem can not be handled well, we can not call it true nightvision HD.


How to make the HD camera look far and wide

Now, HD is not a problem in our video surveillance. And the long-distance monitoring problem has become more and more simple with the improvement of high-power optical zoom devices. Especially in the years of AIO HD chips, the lens plan with larger magnification will undoubtedly become our farther eyes. This kind of development is greatly expanding the quality and scale of our monitoring.


However, because the HD speed dome camera needs, after the completion of HD and long-distance, how to see more wide will become the next direction of the HD speed dome camera. The so-called watch more, originally means that when the camera completes the high-definition and remote monitoring, the camera will not sacrifice the fullness of monitoring, but on the basis of high-definition, far-sighted, but also completion. And such requirement, it is not a easy thing at that time to applicate.


How to satisfy more professional needs under high quality imaging


In the past two years, HD and intelligence have become the concept which is usually mentioned by people, because it is also the primary direction for the future of video surveillance. But, after the advent of the HD era, the pressure on storage and transmission for the backend and midrange is now evident. As a result, in the face of increasingly detailed professional needs, intelligence has undoubtedly become the primary way to deal with the relevant questions, and this also makes us have to touch the already very weak transmission and back-end storage system.


In addition, regarding the professional needs of users, content sorting outside of mass storage is also a major test for the manufacturers, and this will once again deepen the use of intelligence. Therefore, this also puts forward a higher demand for the structured and unstructured processing of data. However, actual application is where we get experience and capital, but very limited.


◇ How guarantee the quality when reduce the cost


when talking about which security is expensive, I am afraid that many people will think of network surveillance. At first, HD speed dome camera also have this question. At that time, the layout of the network HD speed dome camera was mainly composed of the transmission system cost, the storage system cost and the IP HD speed dome camera protection cost. The cost reduction of transmission systems and storage systems will primarily depend on the power of the coding algorithm. Therefore, if the manipulation of capital is only to start from these two aspects, then its role is bound to be very constrained.


In recent years, we usually hear about the test of putting hard disk in front and then relieving the video transmission. Such a change will greatly reduce the video's dependence on network transmission, together with a more reasonable allocation of stored information. This sounds like a good plan for the manipulation of the capital. However, if it is placed in the usual large-scale public security monitoring, I am afraid there is still a long way to go.
