The new Stealth Cam is activated by heat and motion, making it an ideal option for nature photographers. Utilising Passive Infrared Sensor technology, which takes photographs when heat or motion is detected, the BBC Natural History Unit has been using Stealth Cam in a bid to find miniature hippos off the coast of east Africa. A range of digital cameras are currently available, which can be used during the day or at night-time. Features change depending on the type of camera; prices start at £219.99 for a 2.1MP digital camera, £369.99 for a 2.1MP digital camera with a LCD viewer, and £489.99 for a 3MP digital camera with a built-in LCD screen.
