# Quick Start Guide

## Step 1: Launch the Controller

    controller.exe settings.txt

This opens the main control panel. See Controller for full details.

## Step 2: Start All Processes

On the Processes tab, click Start All. This launches:

- 3 capture processes (one per camera feed)
- 3 motion detection processes
- 1 video generator

The process list shows each running process with its PID and status.

## Step 3: Open the Viewer

Click Start Viewer on the Processes tab, or run manually:

    viewer.exe settings.txt

## Step 4: Measure Distance

1. Press `1` to toggle grid lines on
2. Move the mouse cursor to the landing point
3. The distance readout appears in the top-left corner
4. Use the scroll wheel or arrow keys to step through frames
5. Right-click and drag for fast scrolling

## Testing Without Cameras

Use the file player to feed recorded video:

    fileplayer.exe 0 test_video.mp4
    fileplayer.exe 1 test_video.mp4
    fileplayer.exe 2 test_video.mp4

Then start motion detection and the viewer as normal. See File Player for details.

## Stopping

Click Stop All in the controller, or close the controller window (it will confirm before shutting down all processes).
