Multi-Camera Lab Demonstration System
One teacher station — every student sees the experiment clearly
Through multi-stream HD capture from overhead, side, and microscope views synchronized to classroom displays and student terminals, the system solves the common lab classroom problems of details being too small, incomplete views, and back-row visibility. Supports group teaching, in-class quizzes, seat monitoring walls, lab session recording and playback, and cross-school remote teaching observation.

Single demonstration angle; key steps easily missed
Overhead + side + microscope multi-angle switching for complete operational detail
No review materials after class; hard to reflect on teaching
Automatic lab session recording and archival with post-class playback and teaching research sharing
Core Capabilities
Unified Multi-Camera Integration
Network and local camera support with standardized overhead, side, and microscope camera configuration.
Classroom Display Sync
One-click teacher push to project live experiment footage to classroom displays.

Remote Teaching Observation
Cross-school remote lab session observation to promote sharing of quality resources.
Deployment Architecture
Deployed in school labs: school-level management platform for centralized control, cross-platform student lab terminals receiving session commands and multi-stream feeds, teachers demonstrating and monitoring via browser. Shares the same terminals and school platform as the practical exam system — no duplicate infrastructure.
- •School platform recommended in lab server room or campus data center; teacher PC accessed via browser
- •Student terminal client supports Windows, Linux, macOS, and major domestic OS; unified school image deployment
- •Multi-camera devices (overhead/side/microscope) connect via USB or network; unified platform management and monitoring
- •Classroom display synced via teacher PC projection or dedicated display terminal
- •Session recordings and teaching data reportable to regional platform for teaching research and analytics
Recommended Hardware Configuration
Recommendations for a standard smart lab (24 seats). Demonstration and exam share terminals; adjust by subject and classroom scale.
