Review on Mio MiVue C312 Mini Car Security Dash Camera with 2M Sensor, Full HD 1080p Recording, 130° Wide-Angle Lens - Auto Power On, G-Sensor for Emergency Backup - Record in Low-Light Conditions by Omar Malvo

If your car has a DVR, you can have peace of mind. While I wouldn't call it "best of the line" (like the BlackVue), it's a different price point. I display this on the back window of my car and write down any incidents that might occur as a result of a rear-end collision. Luckily nothing like that happened. But I have reviewed the footage and I think this will be sufficient evidence of the incident.
