True phone phreaks freaks will appreciate this GSM doorbell system from Dutch manufacturer Waleli. Once you install the doorbell system, you can let friends and family in remotely by entering a password via SMS when the doorbell is rung. The pizza guy? He’s chill. My mother? Come on in. Angry mob of loyal CDMA supporters or Jehovah’s Witnesses? Buzz off.
As awesome as this system is, it’ll be awhile before you can score one in the US, as it’s just being release in Holland currently.
