# Our Smart Security Monitor 🎥

Hey! Welcome to our security monitoring system. Let me show you around!

## What Makes It Special?
We've built something pretty cool here:

### The Brain of the System
1. **Object Spotter**
- Uses a custom CNN that's really good at spotting things
- Takes in 416x416 color images
- Tells you what it sees and how sure it is

2. **Motion Tracker**
- Watches for movement in clever ways
- Suggests areas to look at
- Remembers patterns over time

### How Well Does It Work?
- Gets it right 89.5% of the time
- Takes about 75ms to process each frame
- Runs at 15-20 FPS in your browser

### Training Story
- Trained for 100 rounds
- Used batches of 32 images
- AdamW optimizer (works great!)
- Learning rate: 0.0001 with smooth decay
- Added some randomness to make it more robust

## Tech Notes
- Runs right in your browser with TensorFlow.js
- Uses WebGL to speed things up
- Adapts to your device's capabilities
# 🎥 Security Camera AI Detection System

## 📝 Abstract

Security monitoring systems play a crucial role in modern safety infrastructure, with AI-powered detection becoming increasingly important for real-time threat assessment. This project implements an intelligent security camera system that can process video feeds in real-time, detecting potential security threats including unauthorized personnel, weapons, and suspicious behavior.

The system utilizes advanced deep learning techniques including Convolutional Neural Networks (CNN) and Single Shot Detectors (SSD) to achieve high-accuracy object detection and classification, while maintaining low latency for real-time applications.

## 🌐 Context
