How to control highway HD IP Camera

How to control highway HD IP Camera
If the network is a single on the highway monitoring system upgrade, then the high-definition picture quality is undoubtedly a real innovation. At present, most of the highway video surveillance systems, image clarity only CIF, D1 and other quality results, once the access back-end storage display device that can render the clarity I am afraid there is room for improvement. The HD equipment is not, only front-end collection of effect, high-definition IP Camera to the road network passing vehicles, license plate numbers, and local features can be carried out more detailed shots. For video surveillance, image clarity is the most critical and most basic needs.
Video surveillance images clearer, more complete picture detail, intelligent analysis accuracy is also higher. Is known, the identification of the premise that the identification conditions recognition screen to meet minimum pixel. When the target pixel is larger, the more clear identification, analytical accuracy is higher. In short, the use of intelligent analysis functions are clearly identified in the image processing filters under the premise. HD front-end products relative to the standard definition, in the same focal length and field of distance condition, the unit area more effective pixels, which is able to analyze the video processing algorithms provide a clearer target information, thereby improving the accuracy of data . Whether for intelligent analysis of pre-analytical processing mode or back-end platform, high-definition picture quality is to improve the accuracy of the important factors intelligent analysis. Thus, high-definition picture quality is not only a visual effect of a single meet, while also providing for intelligence analysis more useful analysis environment.
Nowadays, real recognition for high-definition monitor, mostly refers to the overall definition of the concept, that is, from high end equipment, high-definition storage management platform for high-definition, high-definition decoding, high-definition display and other aspects of the series consisting of HD. The whole system is a high-definition picture on the scene to restore the true, the lack of any link are simply not enough full sense of the definition.
Such as display areas, high contrast display device SD display device, it could be a higher quality picture acquisition processing front end. Definition display devices may have a dynamic super-resolution technology, through each image frame data for analysis, processing, image processing into a low-resolution HD images for display. In addition, for high-speed moving objects highway industry resolution, high-definition display devices can be achieved through motion compensation, motion compensation technology is based on a previous partial images to predict, the compensation current local image, eliminating image appears jagged, trailing phenomenon, to make the picture more clear and smooth. Therefore, the overall high-definition screen can be done to restore the collection of single-mindedness.
You can see that the HD devices available on the market have been dazzling, high overall solution is also more diverse. Security system for an existing highway, you can choose the following modes for system build or retrofit:
1 Overall HD-SDI or HD overall network solutions;
2. HD-SDI and HD products mixed network applications and system components;
3 analog, HD-SDI, HD network camera products, integrated solutions.
HD-SDI system can better complete high-definition image acquisition, transmission without delay and without distortion high-definition display and other sectors, and network HD systems can be more convenient platform structures and systems for the management and distribution. When the project is the construction of monitoring the distance between points is less than 100 meters, the entire system may be taken as a whole HD-SDI system via coaxial cable or optical transceiver direct access to high-definition matrix and output display.
This model applies to small and medium highway monitoring system project definition transformation, and its simulation system while retaining the original wiring condition, update the device to meet the user's habits demand. The use of high-definition HD-SDI and network monitoring system combined application mode, you can capture HD-SDI transmission product is completed, the display will be the front of SDI uncompressed high-definition video signal compression encoding, the packaged into IP data transmission and for sharing and Storage. In the network system architecture, can be a huge flexible system management, remote access, and easy formation of a large platform, but through the use of high-definition HD-SDI video monitor screen, the entire system of monitoring results to the extreme.
