 +====== Motion detect | RPi with Full-HD Camera ======
 +
 +Nowdays, the availability of cheap Full-HD grade camera for the RPi leverages the need for a broad range of project in the fields of security and access control. One of the simplest (while powerful) use of a camera is **motion detect**. Motion detect applied to a RPi can be part of an intrusion detection system, in turn this system itself may be part of a global alarm system.\\
 +Another field of use is the access control system. A camera equipped RPi could manage face recognition on its own and then grant/​refuse access to a place. This later will be part of an upcomming project involving the [[http://​www.opencv.org|openCV]] library.\\
 +
 +===== Principles =====
 +The principle of motion detect itself is very simple. A camera takes a picture let's say every 1s and then apply simple comparison between two successives images. If there'​s more than X pixels difference then it's time to both trigger an alarm and to start recording.\\
