Did you know that video surveillance or closed circuit television has been around since the 1940s? It's been used to protect homes, solve crimes and even put criminals in jail. Who knew they were needed inside animal shelters? The Battersea Dogs & Cats Home animal shelter in London, England is one of the United Kingdom's finest animal shelters. The 150-year-old shelter was mentioned in the London Telegraph as a "regional center of excellence" taking care of abandoned animals until they are healthy. The good folks at the Battersea Dogs & Cats home didn't think they needed cameras until they met an ingenious pooch named Red, a shelter dog with a big secret.
