I have a Driveway Patrol system and it has been working great.
Recently my neighbor got one too after seeing how well mine works. Now
we both get alerted whenever someone goes past either of our sensors.
I'm guessing that the manufacturer never expected to sell very many of
these and have two people close to each other using the product :)

Is there some way to change the frequency, Kenneth?

Looked at the FCC info for these devices and they use a crystal to set
the frequency @ 433.8 so it doesn't appear that there is any 'easy' way
to change the frequency.

I'm trying to work with the neighbor to reduce the range of our
transmitters and receivers in the hope that we can get things tuned to
a point where we can only 'see' our own transmitters. There are
antenna wires inside the transmitter and receiver ends that we are
trimming to try and reduce the range. We are also working to shield
the receivers to try and filter out the neighbor's signals.
