Ganso is Spanish for goose. A goose is considered to have excellent eyesight and to be “watchful and inquisitive”, with strong territorial instincts. This often aggressive, territorial behavior from a goose can be utilized as guard capacity. A goose is intelligent enough to discern unusual people or sounds from usual stimuli. The loud honking will alert humans when the goose is alarmed. These same unique features have been implemented in the Ganso device to protect valuable cargo from theft and perishable goods against contamination by stowaways.
