[ale] a new linux solution for multiple problems

As noted in an earlier posting, I have a bw weather resistent camera
with a 60' cord. I've used this device along with video capture card, a
software package called 'motion' to address multiple issues.
1. I work from home and my office is in the basement. I can neither
hear nor see if anyone approaches my garage door.
a. My daughter arrives from school around 4:30, give or take 15 minutes.
I don't want to lose valuable time, sitting in the heat on the
driveway waiting for the (unpredicable) bus.
b. I recently have had a rash of vandalisms in the area of my backyard
fence, which is a common 'cut through' to another neighborhood. You
must pass in front of the garage area on your way to the fence.
I installed the camera on the framework around my garage door. It was
not too difficult as I could run the cable 90% of the way in the
basement ceiling.
Once installed, I have taken two approaches to keeping track of what
goes on around my driveway area.
First solution is a program called motion, which works with v4l hardware
on Linux. It has a bunch of options, but basically captures a snap when
it detects motion. I run it on a standalone machine as it eats up about
95% of the cpu. I then have a shell script which parses through the
files and displays the latest/greatest on my primary workstation display.
The other solution is to run xawtv remotely displaying the output on my
primary display. Problem with this is that ssh eats a lot of cpu,
apparently transmitting the constant video.
Now, I see the bus pull up (we're on a corner and the stop is at this
intersection). I've captured video of two young men trespassing over my
fence and have resolve this issue with their parents.
My mother-in-law can no longer 'sneak' up on me as I see her drive in
the driveway. :)

I didn't have to buy my radio from a specific company to listen
to FM, why doesn't that apply to the Internet (anymore...)?
