This project is started to catch the person who roams near my house. I don't know my house is perfectly safer than other house. We need to protect by ourselves to keep family.
Basically CCTV is able to capture the image when some one comes and goes like black box in the car. But there are required to work during the day. How to detect the people during the night? Are you going to turn on the light? I don't think the way is good because a stranger will run away if the light is on during the night. In addition to that, If you buy the solution which includes all functionalities in the market, it should be pretty expensive. Therefore I made the solution with RaspberryPI2, Webcam, PIR sensor and Light sensor.
Here is description what it has the functionalities.
PIR Sensor which can be detected when someone is walking or running in front of the sensor. It works based on Infrared sensor inside of PIR. Once I have tested it with 16 X 2 character LCD.
