Remote Metal Sensors Used to Detect Poachers
Interesting use of the technology, although I’m sure it has more value on the battlefield than to detect poachers.
The system consists of a network of foot-long metal detectors similar to those used in airports. When moving metal objects such as a machete or a rifle trip the sensor, it sends a radio signal to a wireless Internet gateway camouflaged in the tree canopy as far as a kilometer away. This signal is transmitted via satellite to the Internet, where the incident is logged and messages revealing the poachers’ position and direction are sent instantly to park headquarters, where patrols can then be dispatched.
