Nowadays, there are more and more intrusion detection systems out there in the market that are designed for home uses. Most of them focus on not letting the intruder get in from the first place, but chances are that there are still ways intruders can break in, or simply sneak in and pretend to be an authorized person. What if there is a surveillance system that can detect and recognize every person that enter an area, and notify the owner if it detects an unauthorized person? That would add an extra layer of security to the properties. Back in the years, user would need to view the CCTV footages from a computer that connects to the camera, but now with smartphones/tablets, user can do everything they could only do in a desktop computer but now in a hand sized device. This project is to develop a low cost face recognition CCTV security system with a Raspberry pi, which can be remotely monitored and controlled by user at any time with their smartphone.
