Motion detection system in java : alert when any one pass before system camera
Description : This is a small example for security system in java which send alert through mail and sound while any trespassers pass before your camera connected to system (computer). The program is developed in java media framework. You need jmf.jar and mds.jar to run that code. For sending mail using java mail service application you need to download mail.jar file. The project consist of only 3 packages. Only you have to do is to create a java application in eclipse. copy and paste the following code to your project. compile it and run. Make sure you had added all the jar files to your project. Create a javasecurityalert wave file. Please provide your feed back through comments. Please rate the post.
