I installed an AUTO-VOX V5PRO Replacement rearview mirror, it has an integrated front and rear-facing dashcam. The downside is it is one of the pricier options, but it has better image sensors they do a good job of adjusting based on the lighting outside. They do take getting accustomed to driving at night, the screen glow was distracting at first. I think you can change the resolution of the recording, I have it set to the highest settings.
Paid for itself when some stoned 18-year-old girl thought it was a good idea to pull a U-turn in front of me. A witness in her car said I was doing 50+ and neither of them saw me coming, I was going so fast. Pulled out the memory card and put it in my laptop, showed the officer the video, and I was going 34 in a 35. The video captured was high enough resolution that it captured my body's reaction as a reflection in the windshield. Still fighting symptoms from the whiplash and concussion from bouncing my head off the soundbar and the side roll bar, this Friday will be 1 year of a constant headache.
