As the title says, I just got a dash cam. (Cobra 840 HD). I'd recommend the Cobra 840 HD to anyone looking at a dash cam (approx. 120$, amazon). I'd always wanted to get one, but didn't want to get some crappy korean dash cam for 20$ with bad quality image capture / features. What I just realized, is why don't the police need to notify us that we're being audio recorded? I'm assuming I need to notify that I'm audio recording in the event that I'm pulled over. But why don't the police need to provide notification ?
