Raspberry PI has the most amazing hardware to create your own simple surveillance camera by combining free/open source software. My end goal is to make automated person/human detection and based on the detection send me an email or push notification with an image. Another important goal is to keep the whole solution based on open-source or free software components/services. Component list: Raspberry PI - model A RaspberrryPI official noIR camera(tested also with USB cameras) Passive infrared sensor(PIR) The flow begins with movement detection, there are roughly two ways for detection: hardware and software.
