AI-Powered Video Analytics for Intelligent Surveillance

AI-Powered Video Analytics for Intelligent Surveillance

Client: A leading security solutions provider aiming to enhance real-time surveillance and threat detection using AI-powered video analytics.

Industry: Security & Surveillance

Objective: 

The client sought to develop an advanced video analytics solution that could identify objects, track movements, detect anomalies, and recognize faces in real time. The goal was to deploy an AI model capable of operating on both edge devices and cloud environments for scalable surveillance applications.

Challenges: 

The project faced multiple challenges, including the need to process high-resolution video streams in real time while maintaining accuracy. The model had to be robust across various environments, such as low-light conditions, crowded spaces, and different camera angles. Deploying AI models on resource-constrained edge devices was critical for enabling real-time alerts. Additionally, reducing false positives in anomaly detection was essential to avoid unnecessary security interventions.

Solution by Indika AI:

Data Collection & Preprocessing: Indika AI curated diverse surveillance video footage from public datasets like COCO and AVA, as well as proprietary sources. Video frames were extracted and annotated using CVAT and Labelbox for object detection, action recognition, and anomaly labeling. Data augmentation techniques such as cropping, blurring, and brightness adjustments were applied to enhance the model’s generalization ability.

Model Selection & Development: To ensure high-performance video analytics, Indika AI implemented YOLOv8 and DeepSORT for real-time object detection and tracking. Autoencoders and GANs were trained for anomaly detection, helping to identify unusual activities. FaceNet and ArcFace models were integrated for facial recognition and emotion detection, enhancing identity verification. Additionally, CLIP and VideoBERT were used for semantic scene understanding and advanced threat assessment.

Model Training & Fine-Tuning: Indika AI adapted pre-trained models from datasets such as COCO, Kinetics-600, and AVA, fine-tuning them with domain-specific data. Optimization techniques, including learning rate scheduling, batch normalization, and hyperparameter tuning with Optuna, improved performance. Loss functions such as IoU loss for object detection, cross-entropy loss for classification, and triplet loss for facial recognition were utilized to enhance accuracy.

Deployment & Optimization: The solution was optimized for efficiency through model compression techniques like quantization (FP16/INT8) and pruning, making it suitable for edge computing. Optimized models were deployed on NVIDIA Jetson and Coral TPU for real-time inference. Cloud-based analytics were facilitated using AWS Rekognition and OpenVINO for large-scale video processing. A high-throughput video pipeline was developed using FFmpeg and OpenCV to handle real-time data streams effectively.

Results & Impact: The AI-powered video analytics solution delivered a 30% improvement in anomaly detection accuracy through deep learning-based threat assessment. Real-time alerts enabled a 40% reduction in security response times. The optimized edge AI models reduced processing latency by 50%, ensuring efficient surveillance with minimal hardware costs. Additionally, the false positive rate dropped by 25%, reducing unnecessary interventions and improving overall security efficiency.

Conclusion: 

Indika AI successfully developed and deployed a scalable AI-powered video analytics solution, revolutionizing surveillance operations with advanced machine learning techniques. By leveraging state-of-the-art deep learning models and optimizing deployment strategies, the client achieved enhanced security monitoring with improved accuracy, reduced latency, and seamless scalability across cloud and edge environments.
