Suggestions for capturing license plate info?

[hewitt_tech]

Unfortunately my car and my daughter and her husband's car have been 
vandalized by low life's who are shooting out windows with some kind of
pellet gun. They struck last night shortly after midnight shooting out 3 
windows. My car had it's rear driver side window shot out and my 
daughter's Toyota (fairly new) had the back window and driver's window 
shot out. The previous weekend my son-in-law had his rear window shot
out.

I believe this vandalism is random because the night my son-in-law 
reported his window blown out the Manchester police said that there were 
reports of twenty other vehicles damaged in the surrounding area. Last 
night there weren't that many cars parked on the street but they only 
damaged our cars. I couldn't sleep last night so I setup a Linksys web 
cam that I have but I found almost immediately that the camera is not 
effective in low light situations. Worse, no streetside window in my 
house would give any kind of picture that could possibly show a license
plate. The images that I could get were pretty poor and when the camera
triggered due to motion, the passing vehicles were mostly a blur. I did 
find out that if you wanted to even see anything of a passing car you
needed to set the motion detected video segment to 5 seconds (the range
allowed with the LinkSys software is 2 thru 5 seconds).  I do have a 2.4 
ghz wireless black and white pin hole type camera that can be operated 
off a 9 volt battery. Since the people who are doing this damage are 
always driving West to East on our street in order to get a better shot 
at the cars, I was thinking about setting up the tiny wireless camera on 
the front dash of my Honda pointing in the direction of travel in hopes 
that I might pick up the rear plates of passing cars.

Another low tech approach I am considering is to wait up next Friday and 
Saturday night and simply wait a few doors down from my house with a 
very powerful light and a cheap disposable flash camera in hopes of 
catching the car's license plate should they decide to return. Of course 
if this is just random harassment, maybe I should just forget the whole 
thing. The police don't seem to be very effective as this vandalism has 
been going on in Manchester all over the city for some time.

A friend suggested picking up a night vision scope in hopes of capturing 
the license number.

Does anyone have any other suggestions?
