This is 3 cameras at the same time. A front and passenger one (you might get it to see the driver, but you would have to position the camera in your field of view). The inside facing camera cannot be rotated, and the angle only captures about one person (or the rear-seats if put in the absolute middle). So this would work for a Uber driver.
The rear camera also works. You can even connect it to the backup function, so when you engage the reverse gears, the rear camera automatically comes up on the screen). I haven't tried that, but I just use it as a camera to record the rear, not to back out. You can switch the modes easily, viewing any of the cameras, or two at the same time (picture in picture).
It's a very good system. I'm removing a star because the angle of view can't be 170, since I can't get it to see the entire front of the hood, and that angle is less than 170. Also, the interior camera can only realistically capture whatever angle the front has been positioned. So if you installed it to the right of the center of the windshield, then it's going to be the passenger. In the center it would be the rear seats, and to record the driver, you would need to put the camera on the driver's side of the windshield, which obviously isn't good since it obstructs the drivers sight.
