As a critical part of Safe City solutions, surveillance systems require secure, searchable, and efficient storage. Despite advances in cameras, many challenges remain:
Huawei’s Video Cloud Surveillance Solution supports video sharing across departments and regions, enabling remote access, online query and browsing, and fast clue and evidence collection.
The Solution offers two storage options, the VCN Video Cloud and OceanStor Cloud, which centrally store surveillance video, protect video data security, support flexible development, and enable smooth expansion.
Huawei VCN Video Cloud
Traditional solutions use different devices for video access, stream forwarding, recording, playback, management, backup, and disk array functions. The Huawei VCN Video Cloud simplifies networking and maintenance and reduces equipment investment with an expandable, all-in-one box solution.
- Each box supports up to 256 channels of video
- Boxes can be stacked to expand system capacity and interconnected for centralized management
- VCN nodes in police agencies are connected to form a surveillance cloud
- One cloud supports up to 200,000 channels of video
The solution manages up to 16 stacked VCNs. A VMU can be added to support up to 128 stacked VCN3000s. VMU functions include unified service access controls, video storage management, video stream forwarding, and intelligent applications.
Open interfaces enable interconnection with other surveillance platforms and devices from major vendors. Distributed deployment with centralized management ensures high reliability with easy scalability.
Seven protection mechanisms are employed:
Secure collection features include AES encryption, digital watermarks, and automatic upload on recovery after a network outage
Multi-level networking supports both local autonomy and unified management
Cloud clustering ensures load balancing and redundant protection of nodes
Convergent architecture significantly cuts fault points and saves investment and maintenance costs
Inter-array RAID protection with Load balancing and redundancy protection
Intra-array RAID protection works even when multiple disks fail; auto-recovery after replacing multiple disks
Hardware protections include dual power supplies, dual BIOS, dual OS disks, independent management ports, and remote reboot
Huawei OceanStor Cloud
The OceanStor Cloud groups together existing storage resources in police departments into a unified resource pool and features a global naming space and unified management interface:
Distributed NAS: Each video file is divided into several parts and stored on different hard disks in different nodes, preventing Single Point of Failure (SPOF)
Layered redundancy protection for data slices supports automatic whole node data recovery
Seamless, flexible expansion from 3 nodes to 288 nodes: A file system can be expanded up to 40 PB without service interruption — the storage and computing capacity increases linearly with the number of nodes
With global caching, hotspot files can be fetched directly from server cache, greatly reducing hard disk access
Load balancing in unified domain space distributes new user requests to nodes according to their respective computing capability and ongoing workloads
Huawei deploys OceanStor 9000 storage in municipal police bureaus and sub-bureaus, while S2600 and S5500 series storage is implemented in local police stations. Surveillance video stored in local police stations is regularly uploaded to municipal data centers for unified management and efficient query.
