The Nofence virtual fence system consists of an app and a solar-powered collar that communicates on mobile phone networks. The collar provides GPS position data. With Nofence, you can use other areas than your arable land for grazing, increase food production and make agriculture more sustainable and protect the environment.

Focus on looking after your animals rather than time-consuming fence maintenance and pre-order Nofence now.

"This is absolutely the future - I don't think I could keep goats without Nofence."
- Anne Aamodt, pilot customer
“There is no doubt that also heifers are able to learn Nofence. After what we observed with the successful use on goats, we had some expectations that also the heifers could learn. But we did not expect such level of success.”
- Knut Egil Bø, Professor, Animal welfare at Norwegian University of Life Sciences
“Putting up fences below the power lines is not a feasible solution - This technology is crucial for success in the power line grazing project.”
- Ellen Torsæter, Environmental advisor at Statkraft


Draw a grazing area in the app and transfer it wirelessly to the collars. After a brief learning period, animals are safely fenced in and know their boundaries.
The animals quickly learn what the signals from the collar mean and turn to avoid the sounds and gentle electric shock. Kits are solar-powered with battery backup.



In a typical situation, the animal returns after stepping outside of grazing area boundaries. If the increasing sound frequency and vibrations are ineffective, a gentle yet unpleasant electric shock turns the animal around.


If the animal continues to exhibit deviant behavior,  the stimuli repeats for a total of 3 rounds. At this point the stimuli are turned off and an SMS message is sent to the animal’s custodian notifying of animal’s locations.


Animals also return on their own after having ventured outside of the fence zone. When this happens, the system is re-activated and custodians are notified via SMS, eliminating the need to retrieve the animal.


Goat Collar 
Solar powered collar for virtual fencing of goats. Contains GPS-receiver, bluetooth, accelerometer sensor and the new LTE CAT-M1 cellular technology with 2G fallback. The collar comes with one battery pack.
Extra Battery 
Custom battery pack, easy to click in and out from the collar housing, using one-hand grip. Same type of batteries that is used in Tesla cars.
Nofence Beacon 
Small bluetooth device that deactivates the GPS receiver in the collars. This helps prevent inaccurate positions when the animals are indoors or in other areas with suboptimal GPS coverage, as well as saving battery power.
Battery charger 
Battery charger to be used on the grid. Adapters available for non-european sockets.
