Ao cool streaming video live broadcast system helps campus "Sunshine Kitchen"
— Webcast solution for video surveillance in campus canteens
Summary:
The cafeteria plays an important role in our lives. Related to our physical health, the old saying goes: the people eat for the sky. For the majority of schools, the catering status of the canteen directly affects the normal life of the faculty and students, so the good dining environment and the quality of the food are extremely important.

07:05:20 Report from the China Daily-Chinese website - "The canteen aunt bones are thrown back into the soup for the teachers and students to drink"
From this we can see that there are still considerable hidden dangers in campus food safety. In order to further strengthen management, effectively prevent the occurrence of food poisoning incidents and ensure the health and safety of teachers and students, we need to strengthen the food safety special rectification. Public supervision of food hygiene and safety. Therefore, we introduced a network video live broadcast system based on video surveillance to realize the "sunshine kitchen." Let the kitchen "exposure" under the supervision of the majority of netizens.
solution:
(North Star Star) campus canteen video surveillance live broadcast system platform, which integrates mainstream video and audio compression and processing technology and video and audio transmission technology and streaming media technology; builds a streaming media monitoring live broadcast platform, and the leaders, teachers and parents of the school can Viewing through various terminal devices, supporting video high-definition effect enlargement and zooming out, real-time monitoring of the working status of the canteen staff in the school.
The system can also be interconnected with the campus video on demand system and the classroom live broadcast system, which plays a huge role in guiding supervision, work evaluation, digital campus and so on.
System functions:
1) Support the equipment of mainstream monitoring manufacturers, which can be connected with the existing monitoring system to complete the live broadcast of the video;
2) Support platform construction for IP-based networks (LAN, MAN, campus, WAN, etc.);
3) Using the standard live broadcast protocol, through the large-screen broadcast system, the monitoring content can be easily displayed on the campus large screen;
4) Support single server deployment, or multiple server cluster deployment and cloud deployment;
5) Support video and audio recording, storage, and on-demand file generation;
6) Support large clusters of concurrent users (≥1000);
7) Support real-time, stable 7*24 hours of operation processing;
8) Support user management and rights management;
9) Support today's mainstream user terminals for real-time viewing;

System Features:
1) Convergence and scalability: It can be combined with the surveillance cameras of mainstream applications in the market, including camera products of brand manufacturers, such as: Hikvision (domestic leading monitoring brand), Tiandi Weiye (national standard drafting unit for security products) Tyco Security Tyco (Security Components Global, USA), Yaan Yaan (the first overseas listed company in the security industry), Dahua Technology (Dahua Technology is based in Central China, radiating the country, surveillance camera military quality, hard products The big brands created by the company are connected through the mainstream streaming media transmission protocol, allowing the integrators and distributors to quickly select the application product docking solution for the user and implement them;
2) Networking and modernization: By integrating the Aku cool streaming video live broadcast system, the information that can only be viewed in the monitoring room is extended to the entire network. The leaders and teachers and students can pass through their own computers and mobile phones. Watch in real time, while supporting more concurrent users to access the viewing;
3) Open and sound: Through the integration of the system platform and the original monitoring platform, it can highlight and enhance the visibility of the campus, and is an important symbol for establishing and improving campus planning and construction;
4) Maturity: In order to ensure that the system can adapt to the network development trend in the coming years, the hardware, network protocols and database systems in the system should adopt an open protocol compatible with international standards. The software is fully owned by Polar Star. Can be expanded according to the needs of users;
5) Stability, real-time: The underlying core of the product has been used in a variety of occasions, which can guarantee stable operation. The hardware device adopts embedded development technology to ensure the bottom layer, and has good stability and real-time performance.
System composition:
1) Live management module
The system supports multiple network signal streams, real-time or delay control of live, broadcast, recording and other functions.
Universal network signal: Supports live broadcast or secondary coded broadcast applications of multiple standard protocols (RTMP, RTSP, UDP, HLS);
Dedicated encoder signal: support multiple standard H.264 encoding devices encoding and output protocol live stream (RTMP, RTSP, TS Over UDP, etc.);
Network surveillance camera signal: Supports Onvif protocol and H.264 encoded network signal (RTSP, RTMP) of mainstream network surveillance cameras.
2) Forwarding management module
The system supports real-time/delayed broadcast of network signal streams of multiple standard streaming protocols to real-time/delayed broadcasts for users to build more personalized applications.
3) Recording management module
The system supports network signal flow for multiple standard streaming protocols, real-time/timed control recording, and resource file generation.
4) On-demand management module
The system supports real-time/timed recording of video file resources and generation of on-demand channel lists of virtual live video files uploaded by services such as local FTP, for users to edit, download, and share late video resources, and provide more advantageous resources.
5) User Management Module
The system provides a complete user management module, which is divided into front-end users and background management users according to user types.
The front-end users are divided into anonymous (visitor) users and registered users. Unregistered users only have video viewing and browsing rights. Registered users have functions such as video collection, commenting, commenting, and logging out.
The background users are mainly administrator users who have system management rights.
User management operations include user addition, modification, deletion, query, registered user audit, user classification, user level definition and other functions;
The super administrator has all the rights of the system, and can add, delete, modify, query and classify the administrator and registered users.
6) Portal Management Module
It mainly includes the news of the station, the on-demand resource channel, the excellent video resource sharing display, the announcement of the site, the Banner advertisement map, and the information of the site.
7) Resource Management Module
Editing and sorting resources such as video resources uploaded by services such as local FTP and video files recorded by the live system module to the on-demand channel, modification, deletion, query, and definition level display.
