Here's a picture of two of four Cyclapse camera systems on the roof of a building in Hay River, Northwest Territories. These systems are unique, in that they are capturing huge amounts of data, one picture per minute. This required some extra effort to allow the battery packs to charge at very low temperatures. This picture for instance was taken when they installed the system, at -35C!
