Introduction:
Video monitoring systems generate huge quantities of video. Because of absence of time or funds, the primary portion of this video is never seen or checked. As a consequence, safety incidents are missed and suspect behavior, to avoid incidents, are not observed in time.
Video analytics aims to reduce the large quantity of video data to make it more systemically and personally manageable. Video analysis monitoring devices analyze the captured video automatically and use the resulting information by marking it with the suitable labels.
With the incorporation of video analysis in network cameras, a video surveillance system is designed to reduce workload dramatically.
Video analytics delivers a host of advantages, such as better employee use, lower storage and server expenses and quicker access to the stored video. Through video analysis, it is possible to set up systems to provide far more particular and targeted data to create greater business value.
Video analyzes and tags video monitoring in real time automatically. Video analysis detects suspicious activities, initiates video recording, and sends alarms, alerts to operators and field workers. Video analytics can offer users early warnings by automatically monitoring video for safety events so that they can avoid crime rather than respond or evaluate it after the event.
Efficient use of manpower:
Video analytics means fewer operators can monitor even very large installations because staff won’t have to watch a number of monitors to detect suspected activity for long hours. The video analysis system will instead inform operators of incidents, such as people moving in confined areas, cars moving the wrong way or somebody trying to manipulate video cameras.
Combining video analysis with video verification enhances monitoring efficiency. If you have notified a operator of an incident in a video analytic application, the operator can check the alarm before sending a security guard. This reduces the number of unnecessary emergency reactions.
Reduced network load and storage needs:
Video analytics, including video motion detection and audio detection, minimize storage space requirement by recording video activity only. Also, the load on the network is significantly decreased by processing the network video itself, called the so-called “intelligence on the top,” since only the video is streamed from the cameras. Axis Zip stream technology optimized for video monitoring reduces bandwidth and storage needs even more
Faster retrieval of stored video:
Video analysis, for example detection of video movement, guarantees that only appropriate video recordings are stored.
Only videos that can possibly include the occurrence are found when it occurs to return to the ancient recordings. For example, a video analysis system that tagged the video stream with appropriate labels can search for the right video images in a matter of seconds during days of saving video.
New business opportunities:
Furthermore, video analysis allows the use of video in external safety apps. Video and data can be extracted from video surveillance streams and integrated with other apps such as retail or access management systems to develop fresh company benefits and open up new company opportunities through business intelligence. For instance, a video analytics scheme at airports can measure the queue time between the check-in and departure point, help direct personnel and reduce waiting time for passengers to a minimum.
Implementing video analytics:
The implementation of video analytics is based on two wide classifications of system architecture: central and distributed. Cameras and sensors are gathered and carried to a central server for assessment in centralized architectures, video and other data. The edges (network cameras and video encoders) can process and extract appropriate data in distributed architectures.
Centralized were the first applications of video analytics in analog systems. The video was transmitted to a digital video recorder in these installations, where assessment was carried out. All the videos had to be transferred— often hours of video without any exciting content— which demanded a great deal of network capability and storage needs. Additional expensive servers for the processing of such big quantities of information were also necessary.
The next generation of video analytics, distributed analysis or edge analysis, distributes video processing where it is most useful, i.e. the video encoder. Digital network video offers distributed intelligence, by spreading the processing to distinct components in the network, overcoming the constraints of central architectures. Analysis at the edge implies that no specific analytical servers are required, as the transmission of information to the main server involves compression on a non-compressed video feed. The outcome is an architecture that is much more cost effective and flexible. Servers which typically process only a few video streams when the whole processing processes are completed can manage hundreds of video streams if some cameras are processed.
Conclusion:
Video analytics make it smarter, precise, more cost-effective and easier to handle video surveillance systems. “Intelligence on the brink,” i.e. processing as much video in network cameras or video encoders themselves, provides the most scalable and versatile video analytical architecture. This not only utilizes the lowest bandwidth, but also reduces network costs and complexity significantly.
The integration of compatible third-party alternatives with open-label applications, including ACAP, leads to a rapidly increasing number of applications–both general and specialized in different sectors. The increasing amount of applications in video analytics generates fresh user advantages and open up fresh company opportunities.
