- The more accurate your real-world dimensions can be measured, the more accurate speed estimation will be. However, due to the way Frigate's tracking algorithm works, you may need to tweak the real-world distance values so that estimated speeds better match real-world speeds. - The more accurate your real-world dimensions can be measured, the more accurate speed estimation will be. However, due to the way Frigate's tracking algorithm works, you may need to tweak the real-world distance values so that estimated speeds better match real-world speeds.
- Once an object leaves the zone, speed accuracy will likely decrease due to perspective distortion and misalignment with the calibrated area. Therefore, speed values will show as a zero through MQTT and will not be visible on the debug view when an object is outside of a speed tracking zone. - Once an object leaves the zone, speed accuracy will likely decrease due to perspective distortion and misalignment with the calibrated area.

- The speeds are only an _estimation_ and are highly dependent on camera position, zone points, and real-world measurements. This feature should not be used for law enforcement. - The speeds are only an _estimation_ and are highly dependent on camera position, zone points, and real-world measurements.

### Speed Threshold
Zones can be configured with a minimum speed requirement, meaning an object must be moving at or above this speed to be considered inside the zone. Zone `distances` must be defined as described above.
```yaml
cameras:
name_of_your_camera:
zones:
sidewalk:
coordinates: ...
distances: ...
speed_threshold: 20 # unit is in kph or mph, depending on how unit_system is set (see above)
```
