XC190W 190° Universal Rearview Backup Camera with Optional Color Guide Lines

-

I previously bought two cameras in the $15-20 range, which claimed to be 170-degrees of vision. They both were flagrant misrepresentations, at most 140 degrees. But on my 2018 Mazda, CX-5 the built-in camera seems to show almost completely side-to-side, so I kept looking for one that was even close. This is the real deal. It's certainly at least 180 degree (yes, hard to believe) with a fish-eye effect. So after hooking this one up (temporarily) I took two photos, which I'll upload if I ever see a photo button on this review page. (Oh, Amazon removed that feature and doesn't explain that anywhere, even in their own help files. Well, I used to write documentation and my programmers never told me when they deleted features either. So look for my video.) If they say it's 190 degrees, I can't really argue with them since I clearly see things virtually to the side and didn't do a careful measurement which would require both sides. I'm guessing there are some folks who might expect elite image quality; I'm not judging that and I also can't account for my $20 display's influence. So I'll leave that to others. For me, it will show that shopping cart coming at me from too close in the shopping center parking lot, and that's what I wanted. Great product.After buying my second one of these I finally got around to photographing the results. It's as wide angle as one could hope for without spending the hundreds of dollars that the new-car cameras cost.

Not as clear as I had hoped
