I started in arduino and electronics only 2 months ago. My father asked me if I can make him some motion security cameras and some motion snapshot cams for his deer hunting leases for a cheaper price than the ones sold in stores. I have done some research but found that the only cheap camera modules are the OV7670 and I have heard that they are hard to work with and take up too many pins to use a motion sensor and SD module with it. I have however found some projects that hack cheap digital cameras with SD storage. Would this be the best way to go? Any advise on hardware and project ideas would be greatly appreciated. Thanks.
