About 1 year ago I read on the X-10 site
that the range was 20 feet. I also saw a
diagram of what I would call "the field of
vision for the motion sensor". However, I
think they removed what I saw, because I
have tried to find it but could not. I
believe the 100 feet that they talk about is
how far it will see (pick up motion). I have
6 of the Eagle Eyes in the yard and it has
been my experience the RF signal will go 15
to 20 feet depending on the obsticles
between it and the Transciever (walls, etc.).
Hope this helped. Dennis
