The WITNESSCAM is a self-recording surveillance camera that’s perfect for the home or office. The innovative, ATmega32-based system features a VGA CMOS color camera, a passive-infrared (PIR) movement sensor, and a 1-GB SD card. The aesthetically pleasing prototype looks like an ordinary alarm detector, but when it detects movement, it silently starts recording. You can control the camera an infrared remote. The interactive camera responds with voice prompts, and the circuit can recognize when the box is open.
When the sensor detects movement in a room it will take a burst of 10 photos with the digital camera. Each photo is taken at 0.5sec interval. After the 10 photos, the camera waits 3 seconds for further movement and if it is detected, the process is repeated until 80 photos are taken.
The photos can then be downloaded to your PC (via the USB connection on the board) for viewing.
