With the ascension of network camera technology and the improvement of quality of product performance, network cameras promotion and application of the follow-up will be more extensive. At present, network video monitoring of the main market is concentrated in the safe city, finance, transportation, education, electricity, energy, operators, prison, etc. Several major industries. Dominated by government and the public security organs and the peace of the urban construction of the project is the network products currently carrying out relatively fast and the number of products use is also more of a field, network monitoring is the first choice of most of the project, in the recent a safe city projects, for the most part, monitoring equipment are used in network cameras, using standard and hd webcam fusion with the way of network coverage, no blind spot monitoring project. In the development of network cameras, highlights the following features:
1, high-definition into the most basic requirements
In the era of analog monitor, the user of fuzzy, is full of snow noise images is lamenting the but again there already, because the best cameras on the market can only achieve D1, pixels in theory at best, only more than 40. Surveillance cameras as security for the first big assistant, simulation class monitor products can not meet the needs of the user, so the "hd" became the first big demand, and had a high-definition image quality, low illumination, wide dynamic, intelligent, and so on to achieve a higher level of demand, just have application value.
High-definition images mainly depends on technology breakthrough, first of all start from improving the quality of the video source. Digital network camera relative to the analog camera, using the progressive scan, commonly used CCD image sensor adopts the AD conversion, optical signals into, digital signal output, avoid the repeated AD transform, image quality small damage, and in color reproduction, signal anti-jamming performance is excellent.
2, low illumination to accelerate the popularization application
As security monitoring by increasingly MinYongHua high-end special field, the application range of the camera is becoming more and more widely, many poor monitoring conditions, dark places also asks to install the versatile camera, especially the low illumination cameras. In addition, in order to meet the needs of monitoring 24 hours a day, a new technology of low illumination cameras has become a monitoring the market to be bestowed favor on newly. At present, the low illumination cameras has been widely used in finance, wenbo, hotels, office buildings, residential area property management, etc.
Now, had appeared low illumination hd IP camera, the camera USES multiple brightening technology, in the rough monitoring environment, low illumination effect is far more than the analog cameras, they also has a prominent advantage, namely ordinary camera under the condition of low illumination to color images fade into black and white images, and the product is still present a color image under low illumination, both static images and dynamic images, can show the administrative levels feels strong, color reduction, less noise, no real trailing phenomenon, etc. Industry experts believe that improved the performance of low illumination will speed up the popularity of high definition webcam, accelerate the process of great age of hd monitor.
3, intelligence into main trend
Intelligent monitoring can be identified from the complex data analysis behavior and type, available commands, data and information, so as to realize alarm, remind attention, intelligent retrieval, such as intelligent behavior. If the traditional video monitoring is a search for the means of criminal suspects, the intelligent monitoring is an auxiliary means to prevent crime, so as to boost the efficiency of monitoring. And, as a result of intelligent device can selectively transmit video, thus effectively save the bandwidth, greatly improve the available network bandwidth. Today, intelligent monitoring has become an important topic monitoring technology development and market demand.
4, ISP (ImageSignalProcessing) encoded chip integration
By integrating the ISP, it not only can greatly reduce the system cost, can greatly improve the stability of the video, optimize the image in the field of optical performance. This to improve the quality of hd webcam imaging has and its important role. At present there are hd IP solutions emerge in endlessly, including sea, TI, NXP, Trident, Techwell, intellectual source and so on a variety of chip manufacturers are proposed with their characteristics of hd IP solutions.
5, standardization,
Whether ONVIF or PSIA, is the enterprise organize form of standards, but from the point of its response to get more and more enterprises, and has very important significance. The next few years, standardization will be hd webcam to market pass.
