1. Industry background
With the continuous improvement of video aggregation requirements, in projects such as smart campuses and smart parks, it is necessary to aggregate the videos of various branches to the headquarters for unified management and control. It is necessary to meet the requirements of TCP/IP environments such as monitoring internal LANs, the Internet, and VPN networks. , to provide users with a low-cost, high-scalability, strong compatibility, and high-performance remote real-time video service platform. It needs to support the unified collection of various video resources from various departments and locations, and differentiated conversion of different streaming media protocols. And form a unified protocol output to achieve multi-terminal live broadcast without plug-ins.
2. Demand Analysis
There are 14 sites on the project site, and the number of videos at each site varies, with an average of about 12 channels. Each site has a video surveillance system and a corresponding hard disk video recorder, and access to the LAN through home broadband. Now all videos need to be connected uniformly. Realize remote unified access to view.
3. Scheme design
The EasyCVR video fusion platform is based on the integrated architecture of cloud, edge and terminal, and has powerful data access, processing and distribution capabilities. Video surveillance live broadcast, cloud recording, cloud storage, video retrieval and playback, intelligent alarm, platform cascading, PTZ control, voice intercom, etc.
For the above project requirements, we can deploy EasyCVR on the public network, and actively register the hard disk video recorders in the LAN of each site to EasyCVR through the national standard GB28181 protocol (only need to configure the platform information in the hard disk video recorder-configuration-platform access-GB28181 access ), and the EasyCVR platform will do unified video aggregation and real-time live broadcast.
Access requirements:
1) The hard disk video recorder needs to be able to access the network where the EasyCVR server is located, and support the national standard GB28181 protocol;
2) The EasyCVR deployment server needs to have a public network IP, and needs to open the specified port and port segment;
3) Support to take the video files in the front-end NVR for video playback, without server-side video recording.
4. Technical Highlights
1. Flexible access and multi-protocol conversion
EasyCVR supports a variety of access methods, including RTSP/Onvif, national standard GB28181, Hikvision EHOME, Hikvision SDK, Dahua SDK, Uniview SDK, etc., supports intranet penetration, and distributes a variety of streaming media protocols, including RTSP/RTMP /HLS/HTTP-FLV/Websocket-FLV/WebRTC, supports mutual conversion between protocols, platform cascading, and provides one-stop video capability services.
2. GOP cache, screen opening in seconds
It adopts GOP cache technology and optimizes key frame extraction to support screen opening in seconds and extremely low latency to improve viewing experience.
3. No plug-in playback, flexible and controllable
It adopts web-side plug-in-free playback, supports reconnection after disconnection, and automatic transcoding.
4. Compatible with multiple types of equipment access
It can quickly access different types of monitoring equipment in various places, and the platform is compatible with multiple types of front-end monitoring equipment to achieve unified equipment management, configuration control, and analysis applications, which is good for old scenarios.
5. Video storage
It supports video recording, retrieval and playback of surveillance video, and the video storage can last up to 90 days, which is conducive to the traceability, retrieval and evidence collection of video data.
