So, this thing is like having three cameras all at once. You've got one for the front and one for the passenger side. Although, if you want to see the driver, you'll have to tweak the camera's placement to catch them in the frame. The inside camera doesn't swivel, and it only really captures one person at a time, or the back seats if you plonk it right in the middle. So, it's handy for someone driving for Uber.

The rear camera does its job too. You can even hook it up to the backup feature, so when you shift into reverse, bam, there's your rear view on the screen. I haven't tested that out myself though; I just use it to keep an eye on what's happening behind me, not for backing up. You can easily switch between the different camera views or even have two on the screen at once (like picture in picture).

Overall, it's a pretty solid system. But I'm knocking off a star because the field of view isn't quite 170 degrees. I can't see the whole front hood, and that angle's less than 170. Plus, the interior camera can only really capture whatever angle the front one's been set to. So, if you stick it off to the right of the windshield's center, it's going to capture the passenger. Dead center, and it's the back seats. If you want to record the driver, you'll have to stick it on the driver's side of the windshield, but obviously, that's not ideal since it blocks the driver's view.
