In this project we tried to help people to use their phone as a movement camera detector . that working with that is really simple.
You should set a timer for application for take a photo and check the environment , if any change is detected then phone send you a message and show you the part of image that changed with a matrix that separate picture to 9 part and if any part was change this message include 1 in this part else that is 0.
That's really simple . just use it and send me your feedback.
