NERP is not exclusively Raspberry Pi, the small computer interest group at Pumping Station:One in Chicago. NERP meets every other Monday at 7pm at Pumping Station:One, 3519 N. Elston Ave. in Chicago.
To do make a security-cam type device with a Raspberry Pi or a Beagle Bone, the software must run on Linux. There are several computer vision based motion detection applications available for Linux. The OpenCV framework can be used to build Computer Vision applications that do heavy mathematical operation on streams in real time. (It also can be used to draw colored shapes on your screen.) If the versatility of OpenCV isn’t needed for a simple camera app there are a number of movement detection and recording applications to choose from. One of the oldest is Motion. Motion is command line driven. It produces its output as a browser viewable video images, stills, and a few control output options. In contrast with writing applications using OpenCV, it’s very simple to unbox and and fire up Motion. With its simplicity comes limited versatility, but it might be suited to your CV needs.
