In addition, all Costco gas stations employ security cameras, which include motion sensing capability for efficient nighttime coverage. The cameras are connected to a digital recorder which allows easy review in case we have an incident at our gas stations. All Costo equipment shelters are equipped with door and motion alarms, and are kept locked during the day. Consistent with our company's “belt and suspenders” philosophy, these and other measures comprehensively protect our gasoline systems, said Hurlocker.
