Tracking Small Animals?

[excel4]

1. Could this system be used to track small animals around a property - cats, skunks, raccoons, etc.?
2. If so, could this be used with 2.4Ghz wifi routers running DD-WRT?
3. If so, what would be a a typical spacing for the routers for good coverage?

I have a number of WHR-HP-G54 routers running DD-WRT. Wi-fi signal levels can be collected via ssh/shell scripts if that is sufficient. Sheel scripts could also be run on the router to process data. A primary use case would to identify approximately where animals are entering/exiting - e.g. tunneling under a fence, climbing over a fence, etc. A secondary use case would be identifying which animal(s) are present based on movement patterns, size, etc.

The routers could easily be configured in a network if that would provide better performance. Daisy-chaining around a perimeter for example. Caveat: there are other wi-fi signals in the area, which could affect signals levels, though channels can be controlled.
