This automated witness camera was built by Alberto Ricci Bitti and have won the Grand Price at Atmel’s AVR 2006 Design Contest. The goal was to build inexpensive easy of use automatic camera which may fit bay the door taking snapshots of persons entering, or using inside vehicle. There are meny areas it can be used.
Design is based on Atmega32 Atmel AVR microcontroller where serial JPEG camera is attached. Movement detection is done by PIR sensor and all information is recorded to SD memory card by using standard file system(FAT16 or FAT32). So all pictures can be easily transferred to PC with no special software. Pictures are taken at 640×480 pixels resolution at every 3.5 – 4 seconds. You can select several recording modes including: PIR activated, timer, continuous and externally triggered. In one 1GB SD card about 25000 images can be recorded.
Camera also can be controlled with IR remote control with sound responses. Software is written in BASIC language because of available FAT and SD-MMC library availability.
