Our customer's Lexus CT200H did not come with a factory backup camera so we fitted it with a Roadtek R20X Pro Duo. This setup kills multiple birds with one stone as it offers not only a backup camera for parking but a high recording quality dash cam as well. With 1440P (2K) front recording and 1080P rear recording. A bonus feature is that it also works as a digital rearview mirror, similar to what's found on some new Toyota and Cadillac/Chevrolet vehicles!
In the pictures below, you'll see the standard rearview display as well as the display with guidelines when the car is shifted into reverse.
