Yes. This device has an over-speed alarm which is triggered when the tracking device exceeds the designated speed limit that is programmed by the user.
To setup over-speed alarm send an SMS or text message to the tracker with the command below:
Message Format: speed+password+space+speed
It will then reply with the message "speed ok," which denotes that the over-speed alarm has been successfully set.
NOTE: Speeds must be in 3 digits. It is recommended that the speed alarm be set over 30km/h. Settings below 30km/h may cause fluctuation of the GPS signal due to cloud cover or weather.
