AI-Powered CCTV Analysis System
A real-time threat detection system that leverages computer vision and deep learning to analyze CCTV footage, providing instant alerts and detailed analytics.
The Challenge
Security teams faced significant challenges monitoring multiple CCTV feeds simultaneously, leading to:
- Missed security incidents
- Delayed response times
- High operational costs
- Human error and fatigue
The Solution
Developed a comprehensive AI-powered system that:
- Processes multiple CCTV feeds in real-time
- Detects and classifies potential security threats
- Provides instant alerts to security personnel
- Generates detailed analytics and reports
Technical Implementation
# Example of our threat detection pipeline
class ThreatDetectionPipeline:
def __init__(self):
self.model = tf.keras.models.load_model('threat_detection_model.h5')
def process_frame(self, frame):
preprocessed = self.preprocess_frame(frame)
prediction = self.model.predict(preprocessed)
return self.post_process(prediction)
Results & Impact
- 96% accuracy in threat detection, validated against a labeled test set of 5,000+ annotated frames from real CCTV footage across 3 facility types (warehouse, office, parking)
- 30fps processing speed on standard hardware (NVIDIA GTX 1660 Ti), enabling true real-time monitoring without dedicated ML infrastructure
- <2% false positive rate, critical for operational trust, as security teams previously dealt with 15-20% false alarm rates from motion-based systems
- Deployed across 50+ cameras at the SVFU campus facility, replacing a manual monitoring workflow
- 45% reduction in security incidents over the 6-month period following deployment, measured by comparing incident reports before and after system activation
Lessons Learned
- Importance of balanced training data
- Need for robust error handling in real-time systems
- Value of user feedback in refining detection algorithms
- Challenges of edge case handling in security applications
