The Development of Video Surveillance System Is Very Good, and Intelligent Application Will Be Appli

With the continuous development of China's Internet industry, the second and third tier cities have gradually entered a period of rapid development, the demand for construction has accelerated, and the application of public safety protection technology and equipment is more and more closely related to the life of residents. For a long time before, the security market was developing commercial cameras, because the demand in the commercial market was obvious.

With the growing demand for security, the video surveillance equipment market is in an upward cycle. From 2010 to 2016, the scale of China's video surveillance market increased from 24.2 billion yuan to 96.2 billion yuan, with an average annual compound growth rate of 25.86%. It is estimated that the market scale will reach 119.2 billion yuan in 2018, with a year-on-year increase of 12%.

Industry development trend

With the continuous development of the construction of safe city, smart city, bright project and intelligent transportation, security has been gradually popularized. In the face of such a broad market, it is not only an opportunity but also a challenge for security enterprises. Nowadays, most cameras have not been able to get rid of the traditional monitoring method of manual monitoring, resulting in the accumulation of a large number of video data, occupying storage resources, poor real-time performance, retrieval difficulties and other problems. The massive video data retrieval brought by massive cameras needs a lot of police force.

In order to solve these problems, in recent years, the development direction of video surveillance industry is mainly "high definition, networking and intelligence". Video surveillance equipment is highly technical, and the innovation and upgrading of the system is also guiding the changes of market demand and creating new market demand.

Recently, after high definition, networking and intelligence, a new round of major technical iteration - Ultra-high definition video is gradually approaching. On January 3, the electronic information department of the Ministry of industry and information technology held a symposium on the development of UHD video industry in Beijing. The meeting proposed that China's ultra high definition video industry alliance will be established, and the action plan for the development of ultra high definition video industry (2018-2022) will be formulated to promote the construction and industrial application of ultra high definition content, and support the industrial agglomeration development and leading demonstration in Beijing, Guangdong and other places.

Ultra high definition camera can solve the problem of monitoring large scenes. One 4K camera can cover the square in front of the railway station and basically see the face of pedestrians. Secondly, with the same field of view, you can see more image details than 1080p camera, such as face, license plate, etc. these details are often very key in practical application.

On the other hand, UHD video surveillance can obtain more details and generate more effective data, so as to promote the development of artificial intelligence to a certain extent and promote the first application of artificial intelligence in the field of video surveillance.

Key technology development

Contemporary video surveillance system mainly includes five key technologies: digital video compression and coding technology (coding), digital video network transmission technology (transmission), massive video data storage and retrieval technology (storage), human / object recognition and tracking technology in video surveillance scene (video image processing and analysis) Motion detection and alarm technology in video surveillance scene (video image processing and analysis).

Nowadays, intelligence, big data and cloud technology make large-scale video monitoring more practical, which can greatly save manpower and monitoring equipment, and will have broad application prospects in the public security industry.

Big data mining: changing the application pattern in the field of video surveillance

At present, in public security work, the most practical application is to find images with the same clue characteristics from massive video data. The biggest technical obstacle lies in the video structure. From the perspective of video analysis and intelligent vision, we can use some intelligent analysis means to automatically collect some commonly used "metadata" information from a large number of pure videos, and re organize and store the video information in the form of data tag for a long time, so as to be used urgently in "wartime" and complete the patchwork of criminal behavior traces.

Cloud technology: promote more balanced, flexible and reliable video surveillance system

Cloud storage technology adopts distributed file system as its basic feature, and combines the traditional three-tier storage architecture (file system, volume manager and raid) into a unified software layer, so as to create a single intelligent file system across all nodes in the storage system. The system data and management data (metadata) of the distributed file system are distributed on each node, which avoids the contention of system resources and eliminates the system bottleneck; Even if the whole node fails, the system can automatically identify the failed node and automatically recover the data and metadata involved in the failed node, so that the failure is transparent to the business and does not affect the business continuity at all.

Intelligent video analysis: towards compatibility, live annotation and virtual layered deployment

Intelligent video analysis is an intelligent monitoring technology based on target behavior. It separates the background and target in the scene, identifies the real target, removes the background interference, and then analyzes and tracks the target behavior in the camera scene.

Intelligent operation and maintenance: make the video monitoring system easier to use

At present, the original intention of the development of artificial intelligence is to solve mechanical repeatability and large-scale computing work, and operation and maintenance is precisely such a field with high-density work intensity. Intelligent operation and maintenance includes historical data management, stream data management, log data extraction, network data extraction, algorithm data extraction, text and NLP document extraction Automated model discovery and prediction, anomaly detection, root cause analysis, on-demand delivery, and software service delivery.

With the emergence of intelligent operation and maintenance, users of video monitoring system do not need to have strong professional knowledge and it skills.

Conclusion: with the continuous innovation and development of information technology, especially the increasing maturity of emerging technologies such as the Internet of things and artificial intelligence, it will increase users' demand for platform software, cause obstacles to the compatibility of software and hardware equipment, and also bring the renewal demand of core technology. The video monitoring industry will enter the process of reshuffle, Traditional equipment manufacturers are facing new challenges of changing to system wide and overall solution providers.

Parvo best way at home HELP!?They need a vet and need to be under 247 vet care or they will DIE. Its not that hard to understand Never,ever force anything down a parvo puppies throat. They will only throw it up or it will just come out the back end. The virus causes the lining of the intensives to slough off so they can not adsorb anything. Forcing things down their throats will only make it worse " I can afford to feed my dogs but I cant afford a vet bill for two dogs " The surrender them or have them humanly put down you waste of skin. There are NO home remedies, your so called research utter BS and you just do not care enough about the dogs to surrender them or have the treated so you rather allow them to suffer a slow horrible death Any one who claims parvo dogs survive just off pedilyte is a lair Since you do not care enough about the puppies to have them treated then surrender them so they can be humanly put down3. Baby Wont Sleep Unless Home...HELP?congratulations for your new child. I actually have a two week historical son, it is robust is not it? Something I did for my son was once lifted up the matress on his bassinett and placed a blanket beneath it to hold him extra upright. I did not do that given that he was not sound asleep in it, I did it given that he's having a predicament with a few publish nasal drip and I was once hoping to avert a few of it from happening his throat, however it sort of feels to be running quality so far as him sound asleep greater too. He too likes to be held while he's sound asleep however propping up his matress and giving him an incline turns out to fulfill him. Something else you would wish to provide a check out if you have not already. Before mattress time provide him a first-class hot tub utilizing the Johnson and Johnson bedtime tub merchandise. When I did this with my son, he was once out like a mild for like three a million/two hours. Good good fortune to you! p. s. one other proposal. ... at my child bathe I bought this endure that whilst you flip it on it makes "womb sounds" that possibly a well funding to place for your child's bassinett and perhaps it is going to make him believe extra comfortable like while he was once for your stomach. Also, studying different persons's responses... the swaddling is a well concept as good!.4. What are some easy things I cand do at home to help out the environment?get rid of ....car, microwave, t.v., lights, aerosol's, plastics and everything that is not biodegradable5. How do I make my indoor cats outdoor cats at a new home? HELP!?gradually introduce them to the outdoors. hold them in your arms while outside so they can see how wonderful it is outside. then, after about 10 minutes of holding, you go back inside and feed them a special treat they like, so they know that the outside is a fun place to be, but they always come home to get all of the love and attention you provide for them. after a few times of this, use a cat harness (available at petsmart) and let your cat feel the ground under its paws. once again, after like 10 minutes, bring her back inside and show her why she does not want to run away (by showing her that you provide love and attention). then, after you are confident with that, let her off the harness, BUT STAY VERY CLOSE! this will show her that she has freedom, but also that you have a wonderful home for her. cats are very loyal, so if you do this gradually, she will always come back. cats are loyal. i heard a story from Hurricane KAtrina that said this man had to leave his 3 cats behind. the floodwater came up pretty high, and the poor man was worried about his cats. once he returned, he found 2 of his cats rescued by an animal shelter. he found his 3rd one under his bed at home, waiting for his return. if the worst thing happens, and they scatter, do not panic. they are probably hiding in the bushes near your house. mines did that one time. lol. also, check to see if cats in your area have been disappearing. my neighborhood has suffered from a series of bobcat/coyote attacks on our local cat population, so our cats come in before dark. i would pay attention to these numbers before letting them live outside. wish you the best of luck!
