Eric Albertsen tries to pick-up radio signals omitted from a tracker device in a Philips TV in Alaba International Market. Greenpeace gave the television to engineers who dismantled it and discreetly installed the tracking device within the casing. The tracking equipment is a state-of-the-art system that operates on GPS, GSM and radio frequency. The device gives regular updates of position, and was used to track the TV from the UK to Africa.
