Intelligent video analysis technology to become the hot topics in security

Intelligent video analysis technology as in recent years, security a hot topic, always seem to have extraordinary enthusiasm, focus on intelligent video analysis of enterprises and more and more, the user needs are increasing, it is only currently available yet mature products applied to the project, some projects are still in the pilot State, problems are solved.

At present we are in the market also saw some intelligent video analysis products, smart analysis module directly placed in the monitored system to the preceding, and more intelligent video analysis is the administrative center of the Central analytical processing.

Today, we will just intelligent video analysis module positions.

Intelligent analysis for front-end and centralized management analysis, it should be said that there has been considerable controversy, two intelligent analysis means the biggest difference is that the former is use front-end chip camera itself, while the latter is the use of back-end computer how pure software for analysis.

But both front-end embedded or back-end software, its functions through the development of the core algorithm is running and the video signal is analyzed and completed. Embedded and pure software difference only to computing platform, which can be done on camera DSP core algorithms of calculation of running and relevant; and pure software mode of operation platform is the one General-purpose computer.

The present use of intelligent monitoring analysis, the vast majority of the back-end analysis mode, troubleshooting, and easily can be effective storage capacity of pressure, but because it is the back-end analysis, always need network transmission of video signals, on the network bandwidth requirements are higher, but that's exactly what it has not been possible to get a proper solution to the problem; the benefits of intelligent analysis frontend can resolve back-end analysis of the challenges posed by the transfer, but the current environment, front end with DSP chip and back-end computer processing capacity is limited, as compared to a lot of video analysis algorithms are substantial, but most of the DSP is not enough memory and processing power to implement effective operation, processing power, reduce the cause of the low accuracy, positives increases.

However, with the embedded system computing capacity enhancements and intelligent video analysis algorithm improvements in video server and network cameras and other front-end devices embedded video analysis module will become a trend.

In a front-end to do video smart analysis of the benefits are real, and transfer to the background is useful alarm information and video, this can significantly reduce the amount of transmitted data, but also reduces the burden on the background save.

Anxun Shi China President Zhang Yong said that application of the predecessor is the next icon/00000_1.html "target =" _blank "> network camera, this is the premise of intelligent monitoring.

With intelligent network camera intelligent video surveillance system in the back end, only to focus on front side camera send over the target data information, without the need for video signal processing and recognition, so the back-end system does not require expensive equipment and complete efficient intelligent video analysis. In this way, because the back-end only the front end of the pre sent/alarm event associated screen display, the control center staff can easily complete the system of monitoring. But this kind of functionality associated with video, video search and playback easier quickly, saving you valuable time. In addition, select embedded video analysis framework for existing traditional video monitoring system upgrade for intelligent video surveillance system, is a low cost and easy to retrofit programme.

At present, most of the network camera manufacturers are initially the "application" as the main product development, strengthen the core DSP processor compute power for front-end smart analysis, it is in today's networks, and storage environments, the most appealing to consumers and users, significantly reducing costs.

At Bosch in the Asia-Pacific region, product manager of Samuel Lee, the former Centre for intelligent analysis and disadvantages for centralized management, he said, directly to the VCA (Video Content Analysis video content analysis) module embedded into coding chip, image content will not be subject to interference, separate from the code stream to record and analyze video images, and centrally manage the Centre on the Central Administration power requirements, server processing power with larger requirements, if a single point of failure, you may affect the entire system running, while centralized analysis of intelligent video surveillance system maintenance cost is relatively high.

It should be said that from the central management to front-end analysis, intelligent video analysis technology still in the trial, what was the previous applications or back-end easier? we can only say that, at present, the vast majority of products known as intelligent front, the DSP processor performance also did not meet the basic requirements, to achieve some basic intelligent video features remains to be done.

Intelligent control technology, software and hardware manufacturers required the combined efforts of excellent processor + excellent intelligence analysis algorithm can guarantee the performance of the Intelligent analysis, is wrong, we will wait and see
