I definitely prefer the wired ones if you don't mind running wires.
Picture quality is better, and they don't broadcast whats going on in
your house to people around the neighborhood. There have been several
articles about people driving down the street with an X10 receiver and
a mini tv set and watching all the nany cams in the neighborhood... I
should try that around here :)

Not from X10. the low light ones are B&W. They are definitely not
"night vision" and I wouldn't necessarily call them "low light" but
they definitely work in "less light" than the color cameras. but they
are inexpensive and easy to work with and if you run cat5 to them
instead of using the built in cables you can always replace them with a
more expensive camera at some later date, and you may decide that you
can live with them as they aren't "bad" just not as good as you can get
for a lot more money. I'd definitely start out with the X10 cams and
see how they work.

I uploaded some of the time lapse that I have done with my "low light"
one on my deck. 2 movies, one from last summer, and another from a
couple of days ago:
http://www.sentman.com/movies/decklapse.mov
and
http://www.sentman.com/movies/grillmeister.mov
the second one has some frames at the end that are after dark. In the
dark they record nothing, but once XTension turns on the deck lights
they can see fairly well, at least good enough to see someone there if
not good enough to recognize them. It's possible that I could get
better resolution with a better video capture device, this one is the
belkin video bus and the output is the fairly small video that you see
there.
i capture a frame every second for a while after a motion hit and save
them off to a directory and then at night I run a script to link them
all together into a movie. it would be nice to have a "last hour" type
movie created live all the time, but I haven't gotten that working yet
;)

That camera in those movies is running through more than 100' of Cat5
cable before coming into my desk and the digitizer. It does
occasionally pick up a line or some other interference, but overall I
don't think that it's going to be a problem unless it's a really long
cable. they make outdoor cat5 I think dont they? I'd pay a little money
for good cable to run as this is not a job you want to do more than
once ;) If you do get too much signal loss, you can get baluns and
other things to add to the cable to get it through, but that will add
$100 or so to the cost of the project as you need one for both ends and
they aren't cheap.
