# Java Security Camera App

A Java desktop application for viewing live streams from both USB webcams and network MJPEG cameras.

## Features

- View live streams from USB webcams
- Connect to network MJPEG cameras (e.g., DroidCamX)
- Take snapshots of the current view
- Simple and intuitive user interface
- Support for multiple camera sources

## Requirements

- Java 11 or higher
- Maven
- USB webcam (for local camera support)
- Network camera with MJPEG stream support (for network camera support)

## Building the Application

1. Clone the repository
2. Navigate to the project directory
3. Build with Maven:
   ```bash
   mvn clean package
   ```

## Running the Application

After building, run the application using:
```bash
java -jar target/security-camera-app-1.0-SNAPSHOT-jar-with-dependencies.jar
```

## Usage

1. Launch the application
2. Select the camera source from the dropdown:
   - USB Camera: Uses your computer's webcam
   - Network Camera: Connects to an MJPEG stream URL
3. Click "Start" to begin streaming
4. Use the "Snapshot" button to capture the current frame
5. Click "Stop" to end the stream

### Using with Network Cameras

For network cameras, you'll need to provide the MJPEG stream URL. Common formats include:
- DroidCamX: `http://[IP_ADDRESS]:4747/video`
- Generic IP Camera: `http://[IP_ADDRESS]/video` or `http://[IP_ADDRESS]/mjpeg`

## Troubleshooting

1. No webcam detected:
   - Ensure your webcam is properly connected
   - Check if other applications are using the webcam

2. Network camera not connecting:
   - Verify the camera URL is correct
   - Ensure the camera is on the same network
   - Check if the camera supports MJPEG streaming
