Poacher detection at fence crossing

Poachers profit from the illegal trade of animal parts. Elephants and rhinoceros are often the target of poachers. In South Africa areas of private reserves agreed to drop fences bordering Kruger National Park. At same time they keep fences that don't boarder the park. Poachers are crossing these fence lines. This paper discusses a work in progress to develop sensors to detect poachers as they cross the fence line.
