ProStalk Nature Cameras are designed primarily to capture images of wildlife and game animals in remote locations. Prostalk can also be used for remote surveillance. The cameras are activated by a wide angle sensor detecting movement. This triggers the fast camera shutter, capturing the wildlife that is in the area. All ProStalk cameras are able to record still images as well as AVI video format. ProStalk cameras are easy to use and have features that are only present on cameras costing much more. All cameras are supplied with 4GB SD Card, tree strap and Instruction book. (Batteries are not included).
