## Abstract

A micro point address is detected in response to an audio trigger. Audio data is detected at a mobile device and compared to at least one predetermined audio sample. In response to the comparison, location data is collected or a location stamp including the location data is made. A grid location identifier is stored in association with the location data in response to the comparison.

## Claims

receiving audio data at a mobile device;
receiving location data for the mobile device;
performing, using a processor, a comparison the audio data to at least one predetermined audio sample;
identifying a doorbell in response to the comparison; and
associating the location data with a grid location identifier in response to the comparison.

### Claim 2 (depends on 1)

The method of claim 1, further comprising:
storing a micro point address with the location data.

### Claim 3 (depends on 2)
