Original Toronto Star caption: An electronic surveillance system in the Etobicoke education centre keeps watch over all the borough's schools and instantly warns security guard John Clovis of any suspicious changes. It reacts to temperature and count changes, to detect fires or thefts and is so sensitive that it picks up the sound of birds chirping.
