With the continuous development of social economy, video surveillance system has gradually sunk from the social public areas (roads, shopping malls, public venues, etc.) to the fields of family, shops, preschool education, etc.
According to industry statistics, the market space of domestic cameras in China in 2017 was 33.5 million, and it is expected to reach 90 million by 2020. If other scenes such as shops and preschool education are included, the overall market will exceed 100 million. Huawei cloud provides video monitoring solutions based on public cloud for such a large-scale video monitoring market.
As a major global supplier of video surveillance solutions, Huawei has extensive technology accumulation and application experience in the field of video surveillance. Hisilicon alone provides chips for 90% of the world’s surveillance cameras. Huawei’s cloud video monitoring solution has served many top-level customers in China. Let’s explain the solution:
Figure 1 Huawei cloud video monitoring solution
1. “Camera access”
First of all, users purchase one or more home cameras of a cloud monitoring manufacturer, and use their personal account password to access the manufacturer’s video monitoring management platform running on Huawei cloud through an encrypted channel. Then as long as the camera and network work normally, the video data has been continuously transmitted to Huawei cloud and encrypted for storage.
2. “Client access”
Users can download and install the camera manufacturer’s client on PC, pad or mobile phone, and associate it with their own camera (account + password, etc.), then they can configure and view the status of the camera through the client.
3. “Live video”
When users view the real-time monitoring, the live video is transcoded and sent through the streaming media server of the platform. Monitoring live broadcast has high requirements for the quality of public cloud network and the performance of storage system. If it can not meet the requirements, there will be jamming, frame loss or frame skipping. With the number of access cameras from tens of thousands to millions or even tens of millions, if the public cloud performance can not meet the needs of the rapid growth of business, there will soon be a serious performance bottleneck, seriously affecting the viewing effect of users.
4. “Video storage” and “video playback”
Video monitoring platform, the most important is the storage and playback of video content, which involves the core of the video monitoring platform: video data storage and reading.
First of all, the data storage capacity of the video monitoring platform is very huge: a video monitoring platform with 10 million users’ cameras, each camera will produce a 1m ~ 5m video file every 30 seconds, which can produce about 200 billion files in a week, about 350 Pb (1PB = 1024tb = 1048576gb) of data. When the number of cameras on the platform continues to increase and more videos of users need to be saved for a long time, the cloud storage system must have EB (1eb = 1024pb) capacity expansion capability.
When the video is stored in the cloud, to be able to read and play back in time, the first thing is to protect the data from damage and loss, so the data persistence (the ability of data not to lose) is extremely important. Another is that when more than 10 million cameras are connected at the same time, cloud storage needs to be able to respond quickly at the same time, and super network access capability is needed.
The object storage service of Huawei cloud is a new self-developed obs3.0 architecture, which supports EB level expansion capability, 100 billion objects per bucket and unlimited capacity; the network bandwidth of a single bucket is 20gbps, the single stream bandwidth is 2.4gbps, the TPS capability of a single bucket is 10 million levels, and the average access delay is as low as 10ms. The overall performance is more than 30% ahead of other public cloud object storage in the industry. What’s more, it has amazing data persistence of more than 11 9s. The probability of data loss of Huawei cloud OBS is 100 times lower than that of a tree hit by a meteorite!!!
5. “Ai intelligent analysis”
With the application scope of smart home becoming more and more extensive, users will no longer be satisfied with the simple real-time monitoring and playback function, and will increasingly favor the monitoring platform with more proliferation functions. The demand for post verification extends to all-round services such as pre judgment, in-process alarm and intelligent detection. Therefore, the video monitoring platform needs to have more comprehensive AI analysis capabilities, such as human intelligence Face recognition, voice detection (crying, crying, cracking, etc.), motion detection (falling, running, jumping, etc.), graphic search (video search by pictures, video search by people) and other needs are gradually applied. In addition, there are more needs such as the generation of children’s or pet’s wonderful moments short films, and the statistical function of family members’ activities.
Huawei cloud object storage OBS service, together with its partners, can provide users with online video analysis capabilities described above, as well as offline video analysis capabilities. Through offline analysis, video can be condensed and frame extracted to reduce storage space, and video clips can be labeled and structured for easy management.
6. The most important last word
All users are very concerned about the security and privacy of the public cloud platform. Huawei cloud is the only cloud security service provider with the advantages of software and hardware integration in the world, and has passed the C-STAR China certification, MIIT trusted cloud certification, netit cloud service network security assessment, MIIT cloud service four level certification, iso27001:2015 and other national security certification standards For global operation, it has also passed the safety standard certification of all mainstream countries in Europe and America, which is safe and reliable. The OBS service of Huawei cloud object storage strictly implements the fundamental principle of “never touch user data” of Huawei cloud. It supports each user’s independent AES encryption, HTTP transmission channel encryption and kms encryption of data storage. Even Huawei cloud can’t view user data, achieving real comprehensive security and privacy protection.
