'drvwymon' is a program that runs on your computer, and monitors your
wireless driveway equipment, then sends a TXT message to your
cellphone when events are observed. This is done with the most
inexpensive hardware possible, namely by tying into the undoubtedly
unused parallel port on your computer. This allows us to keep the
price very low.
Our recommended sensor equipment is the
DCMA-2500 sensor and base station. MSRP is $189.99, I got mine
with a simple google search for just over $100. More

Please note that Dakota sells a Two-Way handheld unit for MSRP $110.
This does about the same thing as DrvwyMon - you hang their unit on
your belt and you'll be immediately and reliably alerted when a sensor
is triggered. It's also a walkie-talkie that lets you talk
immediately to others carrying these units. But you and your
employees already own cellphones, so why spend the money for their
handheld units? Here's why: there is one caveat with DrvwyMon, namely
that it is only as reliable as your TXT message reception, so if 100%
accuracy and immediate notification is mandatory, you may be better
off with the Dakota handheld product.
Obviously you must have your receiver somewhere that it can
communicate with the motion detector, perhaps on the inside of a wall
to the outdoors. You must also have it within reasonable cabling
distance of a computer. Pretty much any wire will do, ideal would be
the old 4 conducter telephone wire they put in the walls of your
house. You could use telephone cord or modern network wire, but it'll
be up to you to make connections.
Lastly, you will need to have some mechanism to send a TXT message via
your computer. If you already have this, fantastic, let us know and
we'll try to set up an interface mechanism for you. If you're already
not sure what we're talking about, have no fear, you can get this via
a free account on GoogleVoice. If you already have a gmail account,
you're halfway there.
- You must have a computer that is always on, or is on at all
times when you'll need monitoring.
- The computer can be running most any operating system, Windows
(2000/XP/Vista/8 whatever), Mac, Linux/Unix, etc. - DrvwyMon is a
Perl script which is platform independent. We recommend ActiveState
- The computer must be in reasonable cabling distance from your
sensor base station.
- The computer must have a parallel port.
- The computer must be continuously on the Internet (wired DSL or
Cable recommended, however if your wireless connection is solidly
reliable it should be fine).
- In summary, an old otherwise-too-slow-to-use-for-any-real-work
computer is ideal for this job!
