    Nofence App

    Create virtual fences with the use of your fingertip
    and get an immediate status update from your animals.
    The App is available on both iOS and Android.

    Give access to healthy pastures

    With a touch of a fingertip, you'll be able to give your animals access to rich pastures and save time and money by not having to build and maintain fences.

    Exclude no-go areas

    Are there any places you don't want your animals to go? No problem. You can easily create exclusion zones in the Nofence pasture, to close off unwanted areas.

    Monitor your herds

    Taking care of your livestock has never been more hassle-free. The app lets you keep an eye on your animals in real time, and you’ll get notified if anything unexpected happens.



    Solar Panels

    Solar panels on both sides of the collar, which are durable and can withstand rough handling. The effect will not be noticeably affected by scratches on the surface.

    GPS Receiver

    Nofence uses both the American system GPS and the Russian system GLONASS, to triangulate the position.


    Used for both receiving the signal from the Shelter Beacon, turning the GPS receiver off, and for limited cross-device communication.


    Motion Sensor

    Detects acceleration along three axes. Used for power saving and further development work to give additional insight into animal health.

    Mobile Network

    Communication to and from Nofence collars work with 2G and 4g (Cat M1)

    Rechargeable Battery

    10Ah battery is charged by the two solar panels. Easy to replace and secured with a double and independent locking mechanism.

    How many extra batteries do you need?

    We recommend one extra battery per 5th goat collar.

    The average battery life for our Norwegian goats was approximately 3 weeks during the summer of 2019. The span was from 1 week to 3 months. This is significantly better in the 2020 version of the product.

    The number of additional batteries you need depends on how frequently you need to change the batteries, and how often you supervise your animals.

    Increased battery life can be achieved by:

    • Creating large pastures where the animals spend a significant amount of time at least 30 meters away from the Nofence boundary.
    • Adequate mobile network coverage within the pasture.
    • Access to a lot of sun, preferably open spaces with significant parts of the day exposed to sunlight.
    • Using Nofence Beacons when applicable

    How many chargers do you need?

    It takes between 8-10 hours to fully charge a battery.

    The batteries cannot exceed a 30% state-of-charge when shipped, because of shipping restrictions.

    We recommend to fully charge all batteries before before training with Nofence starts.
