摘要

Disclosed is a system and method for discouraging an animal from entering an area, a controller for the system, and a method for controlling the system. The system comprises a first unit for attachment to the animal and a second unit for placement within the area. One of the units comprises a sonic generator arranged to generate a sonic signal, and the other comprises a sonic signal receiver for receiving the sonic signal. The system comprises a sonic alarm generator and a processor arranged to generate time of flight information indicative of a time for the sonic signal to travel from the sonic generator to the sonic signal receiver, which the processor uses to determine a distance between the first unit and the second unit. If the distance is equal to or less than a predetermined distance, the processor causes the sonic alarm generator to generate a sonic alarm.
