# Proximity

This tab allows you to verify that the minimum safety distance between drones is respected using two tools:

* **`Proximity Lines:`** Displays yellow lines in real time between drones that are closer than the configured minimum distance.
* **`Check Collisions:`**Counts the total number of collisions over a predefined period in the Timeline.

{% hint style="warning" %}
Note: The default minimum distance is set to **1.5 meters**, and the minimum possible distance is 1m. It is recommanded to use greater distance when you can to avoid any collision issue in real conditions.
