This was my first year second semester project. It is a home security system which uses Raspberry Pi 3, PIR sensor is used to detect the presence of an intruder using passive infrared rays which triggers the pi camera and captures the image and stores it in the firebase. You will receive an email containing pics of the intruder and also an alert on the Home Security app which we created. You just need to install this on the front door of your house and you're all set!
