2.5. Shelter beacon
Environmental factors can cause degraded GPS signals. A roof can interfere with the collar’s ability to
receive accurate GPS signals, which may cause the position to drift. If the drifting position is logged
outside of the Nofence boundary, the collar may emit audio warnings and electric pulses. This is why we
recommend using a shelter beacon if your animals have access to a barn or a shed. The Nofence shelter
beacon is a Bluetooth unit which disables the collar’s GPS receiver. When the collar picks up the signal
from the shelter beacon, the operating mode is disabled. Whenever the animal moves out of the shelter
beacon’s range, the operating mode comes back on.
The reach of a shelter beacon is approximately 10 metres. The Bluetooth symbol will appear in the app
when the collar has contact with a shelter beacon.
To check the reach of a shelter beacon, you should take a collar in your hand and walk around with it to
see when the beacon symbol appears in the app. Physical obstacles such as wall may limit the reach. In
larger rooms, we recommend using several shelter beacons.
If the animals often lay down alongside the outside walls of the building, you should also consider
placing shelter beacons here. Observe where the animals lay down to rest to estimate where the beacon
should be installed.
Be aware that a shelter beacon could make a dent in the Nofence boundary if the reach tangents the
boundary.
