Analysis of Related Concepts of Smart Cameras

<br> <br> current hot smart cameras in the video surveillance market, intelligent product after another, of course, but also a lot of smart cameras, some video analysis algorithms will soon migrate to the network camera, to achieve real-time analysis of the video in the camera and Inspection, to achieve some of the functions of intelligent analysis, such as the current vehicle detection camera capture camera, to achieve regional intrusion and other functions of the target detection alarm camera, the camera to achieve detection and so on.

The intelligent camera has its own analysis function, and the system architecture is simple. At the same time, the current camera DSP processing capability can completely run a variety of more complex analysis algorithms, and the analysis results are basically the same as the back-end products.

The intelligent analysis server should be still a mainstream product in the market. The server products have the characteristics of short software development cycle, flexible project application, and strong adaptability of the transformation project. At the same time, the computational complexity required for more complex intelligent analysis functions is still very large. The complete porting to cameras requires a lot of optimization and improvement of algorithm performance and increase the hardware cost of front-end equipment. The x86-based server is the best choice for running these complex algorithms, the cost is relatively low, and the best analytical performance can be achieved.

Current applications such as passenger flow statistics analysis, face search and analysis, face comparison, traffic incident detection, video content retrieval, and video quality diagnosis are mostly concentrated on server products. There are fewer transplants to cameras, even if there are some. The less computational content is transplanted to the camera for processing. But server products have an indisputable disadvantage, that is stability. Stability is certainly not good for embedded products. Therefore, many manufacturers will still try to optimize the algorithm to transplant various functions into the embedded device as far as possible under the premise of cost control, so as to improve the stability of the system, especially some devices that need to be used in the outdoor environment, such as traffic. Event detection and other applications.

Good intelligent video surveillance software prerequisites <br> <br> video analysis software, the simple act of judgment or phenomena, including path tracing through a series of complex algorithms, behavior analysis, the number of statistics, out of focus detection, abandoned object , Missing object detection, indoor/outdoor flame/smoke detection, etc. It differs from ordinary video surveillance software in that it has more analysis functions. The ordinary one is only a display and operation platform, if the security personnel do not pay attention to the accident in the video. , then it can not be handled in a timely manner, in most cases, can only be used as evidence of after-sale evidence, and intelligent video surveillance software can be pre-warning, in case of alarm.

Good monitoring software for monitoring display interface must have good compatibility, at least mixed support analog/IP camera, so as to facilitate the current market situation, the hybrid system supports analog/IP system to provide users with an optimal transition method This allows the user to smoothly operate the original analog camera and the newly added IP camera in the same system, and achieve the goal of system upgrade and function expansion without spending a lot of money on system reorganization. Different from the hybrid DVR devices on the market, the software-based video management system has the advantages of lower equipment cost, convenient upgrade, and high scalability, allowing users to access advanced monitoring technologies on the market at any time.

The three major categories of intelligent analysis are divided into three categories in the current intelligent video analysis: diagnostic intelligent analysis for the purpose of fault maintenance; intelligent intelligent identification for the purpose of video information verification; and automatic analysis and tracking. Behavioral intelligence analysis.

Surveillance Cameras In the three major categories of intelligent video analysis, diagnostic video analysis mainly focuses on improving the use efficiency of video surveillance and improving user experience. It plays an important role in the maintenance and operation of video surveillance systems. The identification video analysis focuses on the retrieval capability of video information, and the emphasis is on the improvement of the effect of video surveillance applications. In contrast, the purpose of behavioral video analysis is not only the identification of behavioral information, but more importantly the ability to automatically process information. Such as PTZ automatic tracking monitoring. Such video surveillance has not only become an extension of human vision, but has also become an extension of brain thinking.

Autonomous automatic PTZ intelligent tracking enables the camera to perform autonomous PTZ driving on its own pan/tilt and zoom lens, and automatically controls the PTZ camera to perform full-scale pan and zoom of the pan/tilt, and performs a visually-oriented automatic tracking of the locked moving target. In order to ensure that the tracking target continues to appear in the center of the lens in a zoomed-in close-up, the security personnel can see the information more clearly, and can also be used for ex-post evidence. The automatic PTZ tracking module compensates for the shortcomings of the fixed camera surveillance field of vision and is an essential function of a perfect security monitoring system.

At present, China Eagle’s remote monitoring system is more advantageous. China Eagle has ultra-low stream compression, concentrates traffic costs, and can enjoy high-definition picture quality remotely in real-time; real-time conversation can quickly establish communication; infrared alarm can be deployed in areas; and cloud storage can be played back anytime, anywhere. Compatible with mainstream hardware, no need to replace new hardware, direct and rapid upgrade.

D-rings offer another alternative Seal solution to O-rings for use in reciprocating dynamic or rotary applications. They offer the same sealing characteristics as an O-ring and can be used in both low and high pressure application across a broad range of temperatures.

D-rings can typically be retrofitted into existing O-ring grooves with the size often based around the original O-ring size. The flat geometry on the base of the D-ring stops the seal from twisting and rolling, preventing spiral failure often seen when O-rings are used in reciprocating applications. D-rings can be manufactured to standard O-ring sizes, as well as custom sizes for specific applications.
