The beacon connects to collars via Bluetooth. When a collar is in range, the GPS receiver switches off and the collar is marked as being in a safe zone. Once the livestock leaves the beacon's range, the GPS receiver turns back on automatically.
Shelter beacons come with double A batteries pre-installed to make set up easy. All you have to do is mount the shelter beacon to the wall of your barn/shelter. Beacons are designed to be used indoors only. *include a photo of someone nailing a beacon up.
Additionally in the app make sure that beacon scanning is turned on for every pasture that the beacon is present.
Shelter beacons are designed for indoor use only. They are not intended to be used to bypass the system. Pastures have to have beacons enabled in order for them to take effect, so it is not possible for others outside of your account to use beacons to disrupt the virtual boundary. Always ensure that the beacon is not overlapping with the virtual boundary. Unless it is inside of a structure.
