So that it knows how many meters it has in view which it would need to calculate speed based on the time it took an object to move in that definite area. Remember that formula, speed = distance/total time?

Now, if you want, set the maximum speed limit. In case the maximum limit is touched, a flashlight is activated (it is optional to make flashlight blink, use wisely). After this, moving pixels on screen are to be entered (in %). This way you can adjust the sensitivity of motion detection.

The measured speed and noise volume decibel are shown on the display of the mobile device. Easy and straightforward, the Speed Flasher App is definitely one unique app. Try it now, and share your results and thoughts and the app’s work-ability in comments below.
