Traditional surveillance systems can only "see and record" but cannot analyze. Our full series of AI video analytics hardware follows a "keep the front-end, upgrade the back-end" model: deploy alongside the existing system without replacing cameras or rewiring — every existing camera gains an AI brain. It automatically detects safety hazards such as missing helmets, area intrusion, open flames and smoke, and unattended personnel, triggering real-time alerts.

Product Family:

• AI Video Analytics Edge Mini Station (8 / 16 TOPS): Compact fanless, side-by-side deployment; ideal for small/mid parks, shops, school gates and site offices
• AI Video Analytics Edge All-in-One Device (16-48 TOPS): Standard 1U rack, server-room deployment; ideal for centralized room upgrades and zone-wide monitoring
• AI Video Analytics Server (48 / 96-192 TOPS): Monitoring center / server room deployment, clusterable; ideal for chemical, construction, mining and industrial park centers
• AI Accelerator Card (48 TOPS / Edge inference): Plug into existing X86/ARM servers; ideal for old servers + AI brain and scalable compute clusters

Key Values:

• Front-end reuse: compatible with mainstream cameras, no replacement or rewiring, low upgrade cost
• Network unchanged: side-by-side or server-room deployment, upgrades completed in days
