Chemical and hazardous-area video analytics should begin with the operating map, not with a generic list of algorithms. A tank area, truck-loading area, chemical warehouse, pump room, production unit, and site entrance have different visual risks and different response owners. The camera rules should reflect those differences.
Camera groups and common rules
Loading and unloading areas may require smoking, phone-use, vehicle-stay, access-route, and personnel-entry rules. Process and tank areas may focus on smoke or flame, restricted-area entry, PPE, and visible camera availability. Warehouses can combine fire-risk indications, access-route occupation, vehicle events, and site-specific objects. The correct combination is determined by the local procedure and camera view.
Local architecture
Existing RTSP or ONVIF cameras can usually be connected to an AI edge box or analytics server. New isolated points may use AI cameras. Local operation keeps routine recognition and event evidence inside the customer network after deployment. The system can forward structured events and images to an existing platform without requiring every video stream to be sent externally.
Commissioning and acceptance
Before commissioning, review the angle, target size, lighting, reflections, steam, dust, obstructions, night conditions, and normal operating activity for every selected camera. The acceptance plan should define the event, region, duration, output fields, alarm interval, reviewer, and escalation route. Video AI provides visible event evidence. It does not replace gas detection, fire protection, process controls, or emergency procedures.
