the network surveillance camera resolution

Intelligent video analysis capabilities of the network surveillance camera resolution
Analog camera video surveillance system, seems to give the feeling of a kind of "integration", camera and sensor components are wrapped in a small space, if you want to try a different focal length of the camera, probably have to disassemble replacement; Network Camera lens and machine identity to leave, the focal length of the lens replacement is very convenient.
We say that the finished appearance of the core, network surveillance cameras have been able to support video analysis, the reason is an open platform. With the improved performance of the camera chip, there will be more chip resources are developed, so that more intelligent analysis of the IT elements embedded into the front-end equipment, but also allow more third-party video analysis software compatible to reach multiple intelligences options .
Simulation system is a closed structure-end equipment can not meet intelligent analysis function can only be transferred to the back-end storage systems DVR, DVR based on embedded Linux system the same as the open-source structure can be implanted in a different mode of analysis by video transmission to the front-end integration and analysis.

Comparison of front-end and back-end analysis
Network Camera support front-end intelligent analysis, simulation system for back-end analysis, one after the contrast has in theory be able to separate. The front-end the corresponding intelligent analysis, just need to analyze the results of treatment can spread to the back-end platform; while the back-end analysis requires that whole video image transmitted to the DVR, DVR resolution reached the platform, although the processing speed quickly, but can not help but still cause a certain time lag.
Perhaps in a small monitoring project, back-end intelligence analysis not qualify as a "disadvantage", but in the important financial sector or a wide range of monitoring, the meaning of race against time came to the fore.
Intelligent analysis of Network Cameras front support SD card storage
Turning to the pros and cons of problems, in fact, they are evenly divided. In the design, IPC smart front must support the front-end storage capabilities. Perhaps someone in the coursing, IPC supports SD card you can save the cost of the back-end storage. In fact, this view is wrong, SD card storage solutions supporting role: a network failure, the front-end alarm need to use SD card storage; its weakness is that is not conducive to a wide range of video management.
Front-end storage space is limited, so the codec requirements are very strict. I learned H.264 codec, Highprofile main application and network systems, most of the DVR recorders also using Mainprofile standards. The different decompression mode also reflects the final image generation effect.
The simulation system smart "rear to ensure the stability of the system, compared with the IP system intelligent front, emergencies lag does have an impact. Depending on the application different options for different trigger mode. Difficult to weigh the pros and cons of SD card storage can go long, whether analog cameras can be embedded intelligent modules in the future, these are still unknown.
The well-known network monitoring camera comes with intelligent analysis, video analysis of the front to the front-end equipment, faced with an emergency can be the first to respond to the alarm function. Network probes, analog cameras through the back-end DVR to determine whether the illegal invasion of behavior. In the difference between the two, I make a comparative analysis.
