Dash cam suggestions?

influenza

Does anyone have suggestions for a dash camera or surveillance camera? I just got my car a few weeks ago and recently someone at work is messing with my car. A few days ago I found a few droplets of coffee on my hood. I was pissed, but since there was so little I gave the benefit of the doubt and thought it was an accident. However, this morning when I got off work I found coffee ALL over my hood and roof. Needless to say I am furious . I went to security and they said the parking lot cameras only face the entrance and exit of the facility. I'm hoping to put a camera in my car that would be good in low light situations and has a reasonably long recording time since I'm working graveyard. Any help is appreciated.

Also a shout out to Adam's line of car care products. They are simply amazing! I ordered the essential detail kit and planned to wash my car this weekend, but my situation required immediate action.
