The Bark Control Collar uses both vibration and sound sensors (dual-detection) to discriminate each bark from other external noises. A Static Correction is administered through the Contact Points only if both the vibration from the vocal chords and the sound from the bark match the same criteria.Second, the Bark Control Collar has a new patent pending Temperament Learning System. This system contains software that tracks the number of corrections needed to substantially reduce (and in most cases eliminate) the number of nuisance barks. The system has 10 levels of Static Correction. It begins with low-level corrections, however, if excessive barking continues, the correction intensity will increase with each successive bark until the barking stops.
