How it works
What do you need?
The Nofence system consists of the collars worn by the animals, as well as an app that works on computers, tablets and smartphones.
Draw the grazing area
Nofence allows you to create whatever grazing area you want, but you bear in mind the the natural behavior of the animals, the terrain and surroundings. For example, you can give the animals access to water by putting the boundary slightly into a tarn or lake. This allows you to make use of pasture in areas that were previously inaccessible, giving animals access to better, more varied pasture.
Draw the virtual fence around the pasture land in the app. It is important to mind the instincts of the animals when drawing the grazing area and transferring it to the collars. If the area is too small, doesn’t have the variety of vegetation that the goats want or is unattractive to them for any other reason, they are less likely to respect the Nofence boundary. In addition, the grazing area shouldn’t have any sharp angles or excessively narrow corridors. Also remember that GPS works best if the collar has as clear a line of sight as possible in all directions.
The Nofence technology
To understand how Nofence works, you should read the user manual carefully. We recommend walking in and out of the grazing area that you have drawn carrying a collar. Try imitating the possible behaviours of the animals by stopping and turning around in the warning zone. Also try going out the other side of the warning zone and then coming back inside the Nofence boundary. While doing this, check the updates that you receive through the app. It is useful to do all of this before you start training your animals.
It is important to understand that the warning beeps start where you have marked the Nofence boundary on the map. This means that the animals will only turn around after crossing this boundary. The audio signal continues for between five and twenty seconds before the electric shock is administered, giving the animal plenty of time to notice it. During this period the maximum distance has been set at 3 metres, but goats can go even further than that in five seconds, so you should leave a margin of error when setting a Nofence boundary to protect your apple tree or flower bed.
Fitting the collar
You fit the Nofence like a normal collar. Be careful not to fit it too tightly; it is important to consider the goat’s wellbeing. The animal must also be big enough for it not to find the weight of the collar uncomfortable.
Ideally all of the animals in your flock should wear collars, but you could also try using herd instinct to keep animals without collars within, or close to, your specified grazing area. Unfortunately we don’t yet have enough experience with Nofence grazing technology to make definite recommendations with respect to this.
In principle the solar cells on the collars provide the necessary power during the grazing season, but you can also recharge them or replace their battery if necessary.
If the animals are in a barn with a metal roof, the GPS signal will be weaker, increasing battery consumption. That is why we’ve developed the Nofence Beacon, a Bluetooth device that you can install in your barn which automatically turns off the collars when the animals are there.

How does Nofence keep the goats in the grazing area?
If the goats stay within the Nofence boundary, they won’t notice anything at all. If a goat enters the warning zone, the collar starts vibrating and emitting increasingly high-pitched beeps in advance of the electric shock. The shock, which is equivalent to approximately 1-2% of the maximum energy delivered by a traditional electric fence, lasts for half a second. The animals learn the link between the audio signals and the electric shock, and turn around to turn off the sound and avoid the discomfort of the shock.
If the goat still crosses the boundary of warning zone 1 (see illustration at bottom of page), the warning signals are repeated in warning zones 2 and 3.
If the goat crosses all three warning zones, it is reported as escaped and the owner receives a push notification through the mobile phone app. The audio signals and vibrations are turned off and the electric shock is deactivated so the animal doesn’t suffer any discomfort.
If the goat returns to the designated grazing area of its own accord, the system is reactivated and the owner is notified. You should always try to discover the reason for any escape.
Keep track of your animals
Our customers tell us they spend more quality time with their animals than before, because they can focus on looking after the animals, rather than doing maintenance work on their fences. As they get a message through the app if anything unexpected happens, they can feel confident at all times that their animals are where they should be and are doing fine.
Logging on to the user portal (my.nofence.no) through the desktop app gives you access to more information than the mobile app, including grazing statistics that give you a unique insight into the animals’ behaviour and grazing patterns.
