Whats the difference between AM/FM and a DM signal?
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–or 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, which is an 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!
