I analyzed the removed duplicates. Generally, duplicates don't affect alerts. Duplicates only affect the number of lines in speedcam.txt.

1. A numeric duplicate is a completely repeated value. For example:

5.29578,59.32092,2,80,0,0
5.29578,59.32092,2,80,0,0

2. In addition to complete matches, there are also duplicates by coordinates. At different speeds, for example:

-46.61944,-23.70022,1,30,0,0
-46.61944,-23.70022,1,40,0,0

. And with different types of notifications, for example:

-50.81708,-22.91547,2,0,0,0
-50.81708,-22.91547,1,40,0,0


4. And there is a 4th type of duplicate:
Mirror (geographical) duplicates with omnidirectional (360°) alerts.

9.1345300,48.4514700,1,50,0,0
9.1346100,48.4515300,1,50,0,0

This occurs when two real speed cameras are physically located on opposite sides of the road to monitor oncoming traffic streams, but in the database, both points are assigned an omnidirectional angle (value 0 or 360 in iGO).
- How iGO reacts: It triggers a "double spam" effect. As a driver approaches this location from either direction, the navigation engine detects the radius of both cameras almost simultaneously. This causes overlapping audio warnings and visual glitches on the screen.
