AI Video Surveillance Platform

The project consisted of analyzing a real-time video stream and identifying events and the presence of humans in demarcated areas.

Quick Summary

  • The project consisted of analyzing a real-time video stream and identifying events and the presence of humans in demarcated areas.
  • Delivered a system that identifies events and the presence of people in demarcated areas in real time.
  • Delivered multi-channel alert reporting via phone calls, text messages, and email upon intrusion detection.
Tech Stack: Python JavaScript YOLOv3 OpenCV Twilio
AI Video Surveillance Platform

Overview

The system was networked with a set of up to 64 cameras on a LAN (Local Area Network), also using internal camera event detection mechanisms or polling for cameras that did not support these events. Video streams were extracted and passed through the OpenCV computer vision mechanism to detect intruders using a classification algorithm tuned internally for the project. When an intruder was detected, alerts were generated to up to five contacts using Twilio and SMS, as well as emails and pre-recorded calls. In this case study, we delve into the intricacies of our innovative solution that integrates artificial intelligence into the video surveillance area. Our platform stands out as the demand for advanced security measures intensifies, combining state-of-the-art computer vision, machine learning algorithms, and real-time analytics.

Frequently Asked Questions

How does the AI system detect human presence in specific areas?
The platform uses OpenCV for real-time video stream processing combined with a YOLOv3 object classification model that was custom-tuned for the specific environments and demarcated zones of this project. When a person is detected within a designated area, the system immediately triggers the alert pipeline.
Can the system handle cameras that do not support native event detection?
Yes. The platform uses a polling mechanism for cameras that lack native event detection support, periodically extracting video streams and passing them through the computer vision pipeline. This ensures full coverage across heterogeneous camera hardware on the same network.
How many cameras can the surveillance platform support simultaneously?
The platform was designed and tested to support a network of up to 64 cameras operating concurrently over a Local Area Network (LAN), making it suitable for large commercial or industrial premises.
What alert channels does the system use when an intrusion is detected?
Upon detecting an intruder, the system automatically sends alerts to up to five designated contacts using SMS (via Twilio), pre-recorded phone calls, and email. The system is also integrated with home automation software to enable broader coordinated security responses.
How long did this AI video surveillance project take to develop?
The project was developed over two years by a team of one senior developer and one semi-senior developer, covering the full engineering lifecycle from architecture design through deployment and algorithm tuning.
