Nofence have created the world’s first virtual fence system for grazing animals. The system consists of a solar-powered GPS collar and an app. A digital boundary is transferred to the animal's collar. If an animal crosses the nofence boundary and enters the warning zone, the collar starts beeping to warn the animal that it will receive an electric shock. Animals soon learn what the signals from the collar mean, and turn back to avoid the electric shock. This ensures that the animals always stay within the defined boundary – just as they do with electric fences – the only difference is that the virtual fence has an audible warning instead of a visual warning. The virtual fence can easily be adjusted, giving animals access to new areas. With AI we turn big data to actionable insights.
