The storage architecture moves from local NVR to cloud-edge collaboration, and the hybrid model is favored by medium-sized projects
Local storage ensures reliability and low latency, the cloud provides remote access and centralized management, and hybrid architecture is increasingly used in medium-sized multi-branch projects.
Comparison of three architectures
| Architecture | Advantages | Applicable |
|---|---|---|
| Local NVR | Low latency, not dependent on external network | Single site, centralized points |
| Cloud storage | Remote access, maintenance-free | Small stores, scattered locations |
| Hybrid (cloud-edge collaboration) | Balancing reliability and centralized management | Multi-branch medium-sized projects |
Practical methods of hybrid architecture
- Local storage of full volume: Ensure that recording is not interrupted during network outages;
- Key storage in the cloud: Only alarm clips and key channels are uploaded;
- Unified platform:The headquarters can view all branches through one platform;
- Bandwidth control: Dual stream, use sub-stream for upload.
