I started looking at some of the sites mentioned in this thread and I think I'm starting to get an idea of what I need. What are you opinions on the following starting configuration CMOS camera: C328-7640 from http://www.electronics123.com/s.nl/it.A/id.2517/.f?sc=8&category=241 SD storage: DOSONACHIP with a 512MB media card Microcontroller: ?? I'm not sure which microcontroller to choose, I'm assuming it needs 2 serial channels and some memory to store the image while its copying it from the camera to storage. I see that the various chips are programmed in assembler, visual basic, and others. Is the programming language of the chip something to consider? I already know how to program in C, Again, thanks for your input. Sal Polifemo

By the time you buy the camera module, the DosOnChip module and build a microcontroller module and then add a PIR sensor, you could buy a Game Camera much cheaper. Check out the Wildview or Game Watcher. They are less than $100. Don

The wildview camera is worth a closer look, I forwarded the info to the group to get theyre comments. I still want to go forward with the prototype, looking at this long term there are possibilities for image recognition applications and this would be a good foundation for that. I'm interested in you opinions on which microcontroller to choose, for the moment I'm only interested in copying the image from the camera module to the SD storage device. Again thanks for the help.
