This case study explores how computer vision is being used in real-time processing of CCTV streams, enhancing security monitoring capabilities and enabling swift responses to potential threats.
INTRO AND CLIENT BACKGROUND
→ Our client, a leading security service provider, manages extensive CCTV surveillance networks across multiple locations, including commercial complexes, residential areas, and public spaces.
→ They sought innovative solutions to improve their security monitoring capabilities, detect anomalies more efficiently and respond swiftly to potential threats.
Business challenges/pain points
Manual Monitoring Limitations: Human operators can only monitor a limited number of CCTV feeds simultaneously, leading to potential oversight of critical events.
Delayed Threat Detection: Traditional security systems rely on retrospective analysis, identifying threats after they have occurred.
Resource Intensive Operations: Manual monitoring and analysis of CCTV footage require substantial manpower and resources.
Slow Response to Incidents: Identifying and responding to incidents in real-time is difficult with manual surveillance.
Our Solution
→ The data used for model training and validation included:
Extensive CCTV footage from various environments and conditions.
Annotated datasets identifying different objects and anomalies.
Historical data on security incidents to train the models on recognizing potential threats.
