Each sub-system has been tested by monitoring microcontroller-peripheral communications through an emulated terminal (PuTTY) on a PC. Thereafter, the integrated device is run in a quasi-real-life setting in the lab (without the actual pepper spray). The system reliably alerts the cell phone and saves the photograph taken, although picture quality varies with the lighting condition. In particular, image transmission typically completes in < 8sec and a phone call is made.
