WOLFBOXG850 12" 4K Rear View Mirror Camera with 5.8GHz WiFi and Voice Control, Smart Mirror Dash Cam Front and Rear, Backup Camera with 1080P Rear Camera, Dash Cam with WDR, Includes 64GB Card & GPS

It's a very well-thought-out product. I am genuinely impressed by some features such as:1. Both Front and Rear dash cams are continuously recording footage. Both streams are saved as individual files.2. You can swipe on the display screen of this dash cam, to switch between front view and rear view, or even to have both views side by side. This doesn't affect the actual footage, it's just the display configuration that gets changed, not the recording configuration.3. If you have connected the rear camera red wire with your car's reverse prompt wire, the display will switch to rear view reverse cam and lane guidelines shall appear.Thus if your car doesn't already have a reverse camera, this can act as a reverse camera. However, if your car already has a reverse camera, you don't need to use it as your reverse camera and can install it high up on the rear window. I installed it inside the glass. But it can be installed outside the glass too. It took me a little bit to get used to because of a sudden change in perspective of the rearview mirror. Also, it feels a bit weird not being able to look at the passengers in the car through the mirror (because the camera is outside the car). Maybe I'll buy a small convex mirror to put somewhere, just for the sake of being able to check rear view within the car too.

Excellent choice for an always on rear view display with 4k front cam, that records in clear and vivid format. Included 64GB card was a very good rated fur high speed writes. The speed limit alert was an added bonus which can be preset and the alert sound is perfect.

I took it to a Professional car shop and they installed itCamera quality is great. video recording also very clearBut I was disappointed when the reverse lines didn't work.

It’s perfect

Awsome screen and camera. Cigarette lighter fitment needs a diffent way to connect directly to vehicle. Does not work without adapter. Brilliant product easy to fit.

The quality of rear cam is really bad as it shows light reflection on the screens as white lines. The more light it capture the more white lines appear on the screen. The rear cam can’t handle light at night.

It does the job of surveillance and live rear view very well. Now you can spot cars in the blind spot easily. And with hardwired kit parking mode is very useful if you parked your car outside alot. And foremost, 5star for their customer sevice.

sometimes stops working when the engine starts. Need to take out the charger and put again to start working
