This document describes how to build an HD surveillance camera system using a Raspberry Pi. The system uses a Raspberry Pi, camera module, WiFi adapter, housing, power supply, SD card, and motion detection software. The Raspberry Pi runs Raspbian OS and uses the camera module, motion software, and WiFi to detect and record motion events to the SD card. The live video stream and recorded videos can be accessed from any browser using the Raspberry Pi's static IP address.
