To learn more about connecting cameras to the Pi, let's start a project that builds a motion-sensitive security system using multiple cameras.
For this project, our security system will perform the following activities:
It will run for a day on an 8 GB SD card Raspbian install, but it should never be allowed to use up all the storage space
It will start automatically after a power failure and when the system reboots.
It will support at least two cameras, of which one may be the PiCam or PiNoIR.
It will use a webcam image resolution of either 320 x 240 or 640 x 480 to provide movement detection.
It will maintain high-quality PiCam image resolution while keeping the video file storage at an acceptable level.
The following diagram shows the proposed project architecture:
We will continue to explain the features of the preceding architecture as we progress through this chapter.
