Nofence is the world's first virtual fence for grazing animals. The system consists of an app and a solar-powered collar, where the collar communicates with the app and the web portal over the mobile network. The collar contains GPS technology that provides positioning data.

The fencing function only relies on GPS, but we recommend having mobile coverage in all or large parts of the pasture, so that you can make changes to the Nofence boundary when needed, as well as receive notifications if something happens.

You create the pasture in the app and transfer it wirelessly to the collar that the animals carry. When the animal crosses the Nofence boundary, the collar gives an audio warning. During a short learning period, the animals learn to turn around when they hear the audio warning.

The audio warning starts at a low tone, which increases gradually as long as the animal is outside the Nofence boundary. The animal recognises the tone scale, turns, and returns to the pasture to avoid the electric pulse. The electric pulse is only emitted if the collar has played all the notes in the warning field so that it is recognisable and predictable for the animal.

You can keep track of the herd in real time, and you will be notified inn the Nofence-app if something happens.
