My house is right next to a busy intersection that constantly has accidents or people absolutely flying through way over the limit. I keep missing the accidents, just hearing them. I'm thinking of setting up two cameras, one to capture the plates of everyone driving through and logging them in a database with photo, timestamps etc. A second one to watch the intersection itself for accidents. I can also find out who the fuckhead is that drives around at 3am on a weeknight with the subs cranking max volume listening to the shittest dubstep I have ever heard.
