Ringtones for your phone is nothing new, but how would you like to customize the “ringtone” of your doorbell? The MP3 DJ Doorbell from Swann gives you that power. The wireless system is comprised of a speaker unit and a push button doorbell unit that attaches to the outside of your door. Insert an SD card (not included) and use the included software to edit your favorite songs to play any part of the song as the “ringtone”. When the doorbell is pressed it sends a wireless signal to 330ft/100m to the speaker unit. The speaker is powered by 3 AA batteries (not included) and the doorbell is powered by a 23A battery (included). You can even use the speaker unit as a stand alone MP3 player as the SD card can hold up to 600 songs (2GB) – 10000 songs (32GB). The Swann MP3 DJ Doorbell is priced at $49.99.
