Let me state upfront, that the Vantrue N2 Pro is a compromise when it comes to rear camera images. A rear-mounted camera will provide a much more usable image than a camera mounted in the front and facing the rear. The Vantrue N2 Pro dashcam I have is more for Uber/Lyft drivers who want to record their passenger's activities day or night as well as provide a rear-facing outside image.
I'm not an Uber or Lyft driver but felt the rear camera images would still be helpful even if they don't show as much of the outside rear of the vehicle. I also wanted to avoid the hassle of running the cabling to a rear camera and the possible RF interference of some radio stations that some rear camera's create when their cabling runs in parallel with the antenna amp and antenna cabling. The front facing images are sharp but I'd have to say I wish the Vantrue rear facing camera could see more from its front mount. Still, for the price (I bought it during a $50 off sale) I felt it was worth a try.
Thanks for the rec. Just pulled the trigger on one. Did you hard wire it? If so, which fuse did you use?
