Yes, front and rear, bought them when the riots were going on so I would have proof if I had to run over some protestors attacking my car.
I got the VIOFO A129 Duo and I'm happy with it.
At first I had problems finding a SD card that would last; they would just fail for some reason. But I bought a cheap one and it's been going strong for 6 months or more.
I bought one few months ago, put in my jeep. Wish I had put in my van. Idiot made left turn in front of me last Tuesday, totaled my van. He's saying now it's my fault because I "hit" him. Having trouble getting his insurance to respond. Darn airbag burnt my wrists. Ordering one for each vehicle now
Here is mine. I really like it! The whole thing is a screen. Not just one of the little 2 x 2 screens. I got it for my job truck that didn't have a middle window on the camper shell. Couldn't see crap behind me. Quit that job and mounted it to my Silverado.
I got the Kenwood DRV-A601 and I LOVE IT. Around $200. Too many college kids in town driving on their cell phones to not have one. Easy to use, you can download videos to your phone via the app or to your laptop. If I can figure it out, anyone can....
