intruder alert: surveillance sensors to prevent poaching

From The Economist, sensors that detect poachers:

Nouabale-Ndoki’s [Congo] hard-pressed rangers are, however, about to get some high-tech help in the form of TrailGuard, a system of small and easily hidden electronic detection and communication devices. They will soon begin burying radio-transmitting metal detectors alongside elephant trails leading into the park. Authorised hikers through the park will be given transponders that tell the detectors who they are, as with the “identification friend-or-foe” systems on military aircraft. But when poachers carrying rifles or machetes traipse by a detector, it will send a radio signal to a treetop antenna. Seconds later the rangers will receive the intruder’s co-ordinates on their satellite phones. They will then be able to respond precisely, rather than slogging around on fruitless and demoralising patrols on the off-chance of catching a poacher up to no good.

A nonprofit, affiliated with the State University of New York’s College of Environmental Sciences and Forestry in Syracuse, Wildland Security, has created these sensors to aid countries and areas that have the will to save wildlife but not necessarily the person power.

Hmm, surveillance technology in the service of conservation?
