A British team has developed a system to help protect wild rhinos, which could be extinct within the next ten years, because they are hunted by poachers for their lucrative horns.

By using a combination of GPS trackers, heart rate monitors and hidden cameras, wardens can be on site to foil an attack within seconds.

Cameras are embedded inside the horn of the rhino, in what researchers say is a painless procedure.
