You can fall asleep and wake up to them, use 'em for ringtones, voice encoding and now to replace the ding-dong of the ol' doorbell.We're talking of course, about MP3s.Tejas-based NetStreams is due to launch DoorLinX any day making it the world's first IP-based doorbell / intercom system. It features an amplified 4-W speaker and embedded microphone integrated into the slim wall-mounted slab via WiFi and a door latch activation relay to automatically open the door or gate from any NetStream TouchLinX interface.

The magic though, comes when deployed along side NetStream's DigiLinX audio-distribution system you can map any MP3 audio file (up to 500KB) to the door chime. When someone hits the button, the MP3 plays in any assigned speaker, anywhere in the house.Now if Netstreams could just set its price and availability and then bring it to market, we'll be first in line.
