Induction loop camera’s, such as Truvelo, use loops embedded in the road, instead of radar, to measure speed. These camera’s therefore
cannot be found by Radar Alerting or a radar detector. However, by their nature induction loops are in fixed locations and Stinger has
mapped virtually all of them and incorporated them in the Stinger SpotList database. Stinger SpotList Alerting warns you in time using an
audio signal and display message whenever you are approaching an induction loop camera. The most recent version of the Stinger SpotList
can be downloaded from stinger.com and be installed via the Stinger Desktop application on your Mac or PC.
On approaching a speed camera with induction loops SpotList Alerting will generate the following screen:
Your current speed
Your GPS speed, more accurate
than your car’s speedometer.

The DSI displays a warning 15
seconds before the loop trap and
shows the speed limit it has stored
