Spend a little more, this ain't it chief.
Style: Dual Dash Cam Without Card
Cheapest I could find with supposed " solid functionality and features. " You'll be much better off spending 10$ or $20 more to get readable license plates and a dash cam that doesn't break after 2 days.
Unit started flashing the forward facing camera image constantly but still displayed the rear camera. Either a bad unit or overall bad engineering. Not worth risking it on another unit for me.
Insulation was easy, night vision wasn't very good at all, pretty standard using it, similar to other cheap dash cams with a much shorter life.

Easy set up
Style: Dual Dash Cam Without Card
It’s not great quality, but it does the trick for filming any bad drivers that try to con you in an accident and you need evidence. You get what you pay for, but I feel much more at ease driving with this thing recording.

good camera
Style: Dual Dash Cam Without Card
I'm in love with this camera! I've wanted to put one in my car for a long time for my safety, and I absolutely love this one. It's very easy to install, the setup was simple, and the video quality is excellent; everything looks sharp, both during the day and at night. The camera is small, but you can remove the micro SD card and put it in your computer, and everything looks perfect. I feel much calmer and safer driving knowing that everything is being recorded.
