Even though there are various security systems consuming large power are available in market now-a-days, robbery rate is very high. The authors are proposing a novel system to prevent robbery in highly secure areas with lesser power consumption. This system has face-recognition technology which grants access to only authorized people to enter that area. If others enter the place without access using some other means, then the system alerts the security personnel and streams the video captured by the security camera. The face recognition is done using PCA algorithm.
