Swann Wireless has developed an indoor/outdoor doormat unit that is simply placed under a mat or carpet at your home or business entrance. The chime unit is to be placed within 100 ft (30 m) of the mat. It features three customizable chimes that can be adjusted to the volume of your liking. The doormat chime features a 120 + decibel siren that is activated when pressure is applied to the doormat or carpet. This unit is 100% wireless and is powered by 3 AAA batteries for the chime unit, which are not included. There is 1 A23 battery included for the doormat unit, which is 19.2″ x 12.6″ in size. The batteries can last up to six months, depending upon use. The Swann Wireless Doormat Chime does come with an additional doorbell unit, which would trigger the chime unit. It has a Ip45 waterproof rating.
