Most systems use an AM or FM radio wave frequency and operate the same way regardless of the type of signal. Pet Stop® features FCC approved Digital Modulation (DM technology). This higher, clearer method has been proven as the most effective way to guard against false activation and interference from other signals. It also allows for a wider array of multiple frequencies. It is the most effective way to avoid interference if your neighbor has a similar system, or installs Pet Stop® after seeing how well we work for you and your pet!
