What is a Location?¶

A location in AITracker is a directory containing video recordings from a measurement point. It represents a single camera or monitoring spot where traffic data is collected. Each location holds video files that can be analyzed, configured, and processed by the system.

When you load directories into AITracker, the system scans them for video files and displays each folder as a separate location in the location list.

Opening Locations¶

To load locations into AITracker:

Click the Open Directories button in the application
Select one or more directories containing video recordings
The selected directories will be loaded and displayed in the location list

You can select multiple directories at once to load several measurement points simultaneously.

Location Information¶

For each location, the system displays the following information:

Number of video files
Start time / end time
Duration
Whether the directory contains a configuration
Whether the directory contains results
Number of relations, areas, and sections
The active location is highlighted across the whole row, while the details panel on the left shows the preview and active configuration summary for the selected entry

Video file timeline¶

The video files dialog includes a vertical timeline next to the detailed table. It is reconstructed from the location's processed Summary.json, so it preserves the original recording sequence even when files have been removed from the current directory. Recording blocks are positioned by clock time, so empty space represents a gap and parallel blocks represent overlapping recordings. Blue segments are available, yellow segments are missing from the current directory, and gray segments are unprocessed.

Hover over a block to see its index, time range, duration, frame count, FPS, and status. Click a block to select and reveal its row in the table; double-click an available block to open it in the player. Selecting or scrolling rows in the table updates the timeline highlight and its translucent viewport marker.

Use the mouse wheel to scroll through time. Hold Ctrl while using the wheel to zoom around the time under the pointer, or click Fit to show the complete recording range. Tick spacing changes automatically with the zoom level.

view¶

For the selected location, the system displays: - background image - daily traffic profile image

Combining Multiple Directories¶

See the separate article: Combining Multiple Directories into One Location.

Right-clicking (RMB) on a location in the location list opens a context menu with additional options:

Open folder – opens the location directory in the system file browser
Copy configuration – copies the current location's configuration to clipboard
Paste configuration – applies a previously copied configuration to the selected location

This feature is useful when you need to apply the same settings (relations, areas, detection parameters) across multiple measurement points.
