The project uses a digital camera that will be activated upon detecting a movement from a PIR sensor.
The camera module has an output size of 640×480 in high resolution for each photo with approximately 115kB. The photos are in 352×288 size in low resolution and approximately 35kB. It has an internal 16MB internal RAM since it is a CMOS, which can be cleared when the battery is removed. To power the CMOS sensor, a step-up converter is used by the circuit to step up the 1.5V battery t a 5V supply. A USB chip onboard is available for controlling the USB port for downloading the pictures to a computer with the software included on the CD.
A burst of 10 photos with 0.5sec interval for each photo from the digital camera will be taken when the sensor detects movement in a room. The camera will wait for 3 seconds, after the 10 photos, for further movement. The process is repeated on detection until 80 photos are taken. For viewing, a PC can be used to download theses photos through USB connection. The low quality can take 80 while 20 for high quality.
