Phone Call Detection System
1. Background
In environments such as oil depots, gas stations, and chemical plants, the use of mobile phones can trigger fires or explosions due to the presence of flammable materials. Similarly, in medical facilities, mobile phones may interfere with sensitive medical devices. During driving, phone use can distract operators and endanger lives. Manual supervision is limited and often ineffective—therefore, intelligent video monitoring is essential.
2. Product Overview & Workflow
Product Overview
Fuwei Vision’s AI Phone Call Detection System is an intelligent image recognition solution based on real-time video streams. Using advanced deep learning and big data analytics, it replaces manual supervision by automatically detecting and alerting unauthorized phone usage.
The system utilizes existing surveillance cameras — no new hardware is required — and provides real-time detection and instant alerts for rapid response.
Workflow
-
Front-end cameras continuously upload live video streams to the central server.
-
The AI detection engine analyzes the video feed in real time.
-
When a phone call is detected, the system captures the event, saves evidence, and triggers alerts at the control room or local monitoring points.
