Truck Motion Detector

Description

Place the phone in the holder or lean it against the glass.
Aim at the vehicle in front of the vehicle and press START.
As soon as the machine that stands in front of you starts moving, the application will start beeping.
With two fingers you can increase and decrease the size of the aiming square. One finger can move it around the screen.
Movement is tracked only inside the aiming square.
There is a scale setting intensity. If the car cabin is moving excessively from the wind and passing cars, then adjust the threshold of the signal with this slider.
If three bells are turned on, the application will give a signal until you press the stop button. If you press one bell, then the signal will be sent as long as there is movement in the target square.
