[Request] Help me catch some people vandalizing my girlfriend's house?

For the past few months some people have been coming to my girlfriend's house and committing sporadic acts of vandalism. It's gotten to the point where her father has bought security cameras. Last night we got a bit of it on film and I have some pictures and was wondering if there was anything at all that could be done to enhance the pictures or help them at all.

There are a few pictures here: http://imgur.com/a/grcuL#11

If anybody could take a look it would mean the world to me.
