## Customer Reviews

### ⭐⭐⭐⭐⭐ Finally, a piece of mind while driving in a chaotic world.
*by G***A on August 18, 2025*

Fam!!! Hear me out!!! It's worth your money!! The quality is so excellent even the video quality is excellent. The camera functionality is easy to navigate. You're able to adjust it however you please. It doesn't bring up glare while driving at night and it comes with 24-hour recording. The rear view camera will wrap around your original real View Camera. It does come with the SIM card. It comes with the Wi-Fi for you to connect. I bought the one with the GPS, which shows on my review camera. You'll see the direction and the driving speed you're going. I find it helpful for your back camera. The line is very long. You will have extra for a compatible car. This makes me feel comfortable because now I'm prepared for any mishaps and can easily inform the authorities and the insurance company. The only thing that isn't ideal is that you have to connect it to the smoke socket.

### ⭐⭐⭐⭐⭐ Great Picture Quality. The camera can see better than I can at night.
*by E***R on August 28, 2023*

It really is a great dashcam and backup up camera. The picture quality is amazing and when it's pitch black at night, the camera has a great viewing ability. Truly amazing. I had a friend yesterday after installing it that it looks like watching a movie.I know installing it is intimidating and I had a friend help me but it's worth saving $250-$400.Here are steps and what to look out for:1.) Remove passenger side A arm, that was on my side on my ford f-150 2007 for the fuse box.2.) Remove fuse panel and use a circuit tester to look for 10 and 15 amp rated fuses that are insignificant like hazards, cigarette lighter (don't tie into airbags, ecm, etc in case something went wrong). The yellow wire with the fuse is your constant power and the red wired fuse is your 12v. Test with key on and key off either side of the 2 holes on the fuse. Make sure to ground the black wire to a bolt near the fuse box because it can't be a painted surface for a good connection.Dashcam fits over the rear view mirror with straps or adhesive tape.3.) Remove tailight on passenger or driver side, depending on your vehicle. Run other end of camera under the frame (mine was the frame due to bring a truck) with zip ties up until above the running board. Remove weather stripping rubber next to seat and floor of front seat. Poke hole where wire junction is in the rubber to feed wiring up into the car/truck. (Easier than removing interior floor board). Run up A arm and tuck behind visor. *Don't run into hole by foot pdeals for 2 reasons. There is a hot exhaust manifold and there is barely enough length of wiring*.4.) Poke firmly and I mean firmly to get a good contact with circuit tester (not a multimeter) on reverse light wire. Should be one of two. Put car in reverse, take key out with emergency brake on or have someone else reverse the car while testing it. Ground black wire near unpainted bolt by reverse light and clamp down on t-tap with existing reverse wire and new red wire for 12volts.5.) Use T-taps and attach wire (believe its red) that's not black to the 12v wire you tested with a circuit tester. Attach black wire to ground. Use adhesive tape and in my case for best visibility, zip ties to back up camera. May want to use a fuse relay in case of a short in the future to avoid damaging wiring harness. Run up A arm and plug into rear view mirror dashcam. Great customer service that will call you back and give you technical support fir the installation. I ended buying the oem wolfbox g840h dashcam mount so it goes directly to my windshield instead of over the previous rear view mirror. Much better in terms of aesthetics so I recommend doing that. If you do that, thieves will never know its an aftermarket accessory they can steal.You're all set! I hope this helps as that's what I want instead of a video because it's intimidating for the first time.

### ⭐⭐⭐⭐ I really like this BUT
*by V***R on March 26, 2022*

Overall, I really like this for my 2011 Kia Optima which has the standard factory radio and no backup camera. That's not to say it's perfect because it does have nuances that are less than desirable.Using this fake mirror effectively requires a certain amount of discipline, good situational awareness, and patience. If you have an older vehicle that you do not want to or can't afford to install an aftermarket radio with backup camera, then this is a good alternative. If you can afford an aftermarket radio with backup camera, then that is the way to go.Installation is not difficult. Anyone who can handle minor maintenance on your vehicle should be able to install this in about an hour or two.Pros+ high quality, does not feel cheap+ superb daytime image quality in the right conditions such as sun in front of you+ backup camera for parking it works well and has real time adjustable view+ touch screen controls are simple and easy to use+ I like the fact that it records front and rear for safety reasons+ screen brightness can be adjusted by sliding up-down on the right side of the touchscreen++ during the day swipe up to brighten, at night swipe down to dim the supernova headlightsCons- when the sun is behind you it is usable but creates reflections and a glare- nighttime image quality is complicated-- no traffic behind you, it works well-- if there is traffic behind you, it looks like a merged super novaCaution- cars and objects are much closer than they appear- during the day a green blue flicker caused by contrast light conditions can be distracting- during the day, the superb image quality can be distracting odd as it sounds- screen reflections can take you an additional second to view the rear camera properlyAgain, I like it overall for its quality and safety reasons. If you can't afford an aftermarket radio with a camera, then this is a good option if you're patient and disciplined enough to use it wisely.
