Motion Detectors: Infra-Red vs ??

["(PeteCresswell)" <x@xxxxxxxxx>]

I'm starting to dabble in home automation.

For starters, something called mControl running on a Windows Home
Server box and a few Insteon modules:

- A motion sensor: http://tinyurl.com/apkun8

- An AC On/Off switch: http://tinyurl.com/cmuymj

- A USB adapter to let said modules communicate
  with the server: http://tinyurl.com/lykqjt

The Question:
Is infra-red the best solution?   Primary application would be
detecting deer and smaller animals in order to trigger
something-or-other (haven't figured out that part yet... in order
to reduce deer damage.
