Pet Stop works just as any other pet fence would.
A transmitter emits a boundary that contains your pet, if they approach and ultimately cross this boundary, the receiver emits a warning or physical correction.
One of the many things that sets Pet Stop fence systems apart is they’re method of communication.
Most pet fence brands use FM radio signals and occasionally AM, which work just fine usually.
Pet Stop on the other hand uses Digital Modulation (DM) which has proven to be a more secure and reliable method.
This is a variant of AM signal, and it is actually used by air traffic controllers.
Pet Stop uses AM signals, and digital techniques to get the best-uninterrupted signal possible!
