You can configure alerts on their own. 

There are two alert types: 

✅ Instant Alert: Triggered immediately when a vehicle exceeds the defined speed threshold. 

✅ Duration-Based Alert (Recommended): Triggers only when the vehicle exceeds the defined speed threshold for a set duration (for example, 10 mph over the posted speed limit for 60 seconds). 

We strongly recommend using duration-based alerts, as they provide more consistent and accurate detection of speed violations and help reduce false positives caused by brief speed fluctuations. 

To set up a PSL alert: 

1. Go to Admin > Alerts. 
2. Select Add Alert or edit an existing alert. 
3. Choose Posted Speed Limit as the Alert Type. 
4. Under Trigger alert when speed exceeds, select either: 
   1. Posted Speed Limit, or 
   2. PSL by and enter the threshold (for example, 5 mph). 
5. Under Duration, choose: 
   1. Instant, or 
   2. Show violations that exceed by and set the duration (for example, 10 minutes). 
6. Click Add Alert to save.
