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.

  1. Avoid costly fence maintenance
  2. A simpler approach to herd control
  3. Let nature decide where animals graze
  4. Better and more varied pastures
  5. More sustainable farming
  6. Better animal welfare for your livestock
“I’m delighted that Norway is developing technology that will allow us to make better use of our pasture resources.”
-  Jon Georg Dale, Norwegian Minister of Agriculture and Food

"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



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


If the animal crosses the boundary of the first warning zone,  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.

About Nofence

The Nofence technology has been in use since 2014, and is worn by grazing goats, sheep and cattle in Norway today. 

We who work in Nofence know and love agriculture. Several of us tend to livestock on a daily basis. This means we're developing a product and service that is crucial to our everyday lives. Sustainability and animal welfare is always the primary focus of our efforts. 

Our vision is to contribute to simpler livestock handling, sustainable food production and better use of land resources worldwide.
