+# 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
