# Geofences

Geofence conditions fire depending on whether an asset with GPS coordinates (trackers, mobile assets) is **inside** or **outside** one or more areas.

## Settings

Choose **Geofence** as the comparison type in the IS configuration:

| Field                   | Description                                                 |
| ----------------------- | ----------------------------------------------------------- |
| **Geofence Comparison** | **In the areas** or **Outside the areas**.                  |
| **Geofence Areas**      | Click **Select Geofence Areas** to draw the areas on a map. |

## Drawing areas

1. Use **Search for a place or address** to move the map to your site.
2. Pick a **Draw tool**:
   * **Circle**: click on the map to drop a circle, then drag to resize it.
   * **Polygon**: click to place the corners of the area.
3. Every area appears in the **Areas** list on the left. You can define several areas; the counter at the bottom shows how many are defined.
4. Click **Save**.

## Tips

* To detect that an asset **stays** outside an area for some time (instead of a single position outside), combine the geofence condition with [Temporal Control](/actions-formerly-rule-engine/temporal-control.md), e.g. persist duration 10 minutes.
* Use **Trigger Once** so that the action fires once when the asset leaves the area and again only after it has returned.
* Switching threshold range is not available for geofence conditions.
