I read here in one magazine that you can connect a microphone to the doorbell, and if someone rings, the signal is transmitted to the computer, where it is digitized and turned into a graphic file, which is then animated, archived and sent via modem to a special server that sends you a message that someone is ringing your doorbell. And all this will take only 40 minutes!
