The acoustic doormat is an effective and discreet entry security solution that can be used universally. Simply place the doormat under a rug or doormat. The signal transmitter is connected to the mat via a thin cable (10 m long), allowing for optimal placement. It is also suitable for open doors or hallways. Depending on the setting, a loud alarm sound or a loud or soft gong sound will be triggered immediately upon stepping on it. As a cat bell, the cat sits on the doormat in front of the closed house or patio door, and the signal sounds immediately inside the home. The mat is suitable for use in a dry location and should not be exposed to rain or standing water. It is battery-operated with 1 x 9 V 6LR61 battery (not included).
