<entry key='filter.distance'>25</entry>

I have the filter <entry key='filter.distance'>25</entry> set in version 6.5, but when I review the replay, I still see around 8 points within a 30-meter range and in 7 seconds.

8 points in seven seconds, you have an update frequency less then one seconds?

Which device brand / model do you use?

The Sinotrack ST901L 4G model is a bit confusing. According to the documentation, the minimum reporting interval is 10 seconds. So, it's unclear how it's even possible for updates to occur every few seconds.

Another question: Could it be that the live tracking interval is set to 10 seconds, providing "real-time" updates, but the data saving interval is set to a minimum of 30 seconds? This would mean live tracking appears to be in real time, but the database playback would only reflect updates at 30-second intervals, potentially overloading the database.

Are you sure you had this filtering at the time? There are no other filter-related configuration? Which file do you have this in?

This is my config in opt/traccar/conf/traccar.xml

Looks like this is happening only for turns right? Based on your screenshot before and after the turn the distance/interval of update is larger than during the turn.

Any suggestions ?

Yeah, test it more, just a straight road, drive slowly, how many updates in 1 minutes. Does it get filtered ?
