Features

  • UPGRADED STUNNING 4K UHD - With the front cam's resolution upgrading to 2160p from 1296p as of December 1, 2022, this G840S rear view mirror camera can record you 4K front images and 1080p rear images. The full rear display is 1.5 times larger than an ordinary rearview mirror, which has significantly reduced rearview blind spots.
  • 12'' LARGER SCREEN & BROAD VIEW - Upgraded from most rearview mirror cameras, WOLFBOX 170 front, and 140 rear lens provide an ultra-wide view, minimizing the blind spots for safe driving/reversing. With the smart screen split function, you can observe a dual-lens display simultaneously. With a 2.5D curved screen, the body is more smooth and more suitable for the curvature of the human retina. Its OEM looking makes the mirror camera perfectly integrate with the existing mirror.
  • CLEAR IMAGE & ENHANCED NIGHT VISION - With a built-in high-quality chip, the WOLFBOX mirror camera records 4K front and 1080P rear videos. The mirror dash camera applied an upgraded low-reflectivity LCD to reduce reflection during the day. With incorporated WDR&HDR tech balancing the lights, and the help of a starvis sensor and 6-glass lens to capture higher quality images, driving at night or in any challenging lighting situations should be more effortless.
  • GPS TRACKING ALL THE TIME - With the external GPS antenna plugged in, you can view the GPS info on display while on the wheel. Playback recorded videos on GPS Player, not only can you check the double channel videos on one screen, but also accurately trace back all the GPS metrics.
  • 24H PRECISE PARKING MONITOR - Aside from loop recording for safe driving, your car will still be in safe hands after being parked. The time-lapse mode is there to monitor at very low fps which saves power and capacity while having everything recorded.

    • Great dash cam/smart rear-view mirror for the price
TLDR: Your satisfaction with this item will depend on your need. If you want a all in one device - dash cam/rear camera/backup camera/GPS Speedometer/compass and the occasional rear camera view because your view is blocked - this is a must buy. But if you're planning on using this in rear camera mode all the time - this may not be the product for you. I was surfing YouTube one day and came across a video of a Smart Rear View Mirror and was intrigued. I have a midsize SUV and with the cargo area full of boxes, balloons or people, I can't see out of the rear view mirror. I always wanted a rear view camera as well and this crossed off a lot of my needs. We've come a long way when a touch screen product like this with all these features is a little over a hundred dollars. I went with the 12" because I saw how the 10" rear view mirrors had to extend the camera out so your original mirror doesn't block it. So it ends up being 12" anyway and doesn't look as clean. But I made sure I measured everything and that my sun visor wouldn't block it before getting the 12". After two weeks with the mirror, here is my list of Pros and Cons: Pros: -Quick install. I mounted the rear camera with the double sided tape to the glass of my SUV tailgate. That way it doesn't get dirty or wet. The higher position also reduces the camera being blinded by headlights straight on at night as opposed to it being mounted by your license plate. -At night, I find the screen at the lowest brightness works well. It's no brighter than the cars infotainment screen. -The large screen makes navigating and watching recordings easy. The UI was surprisingly easy to navigate. -Comes with a 32GB Mini SD Card so you're ready to go at the start. But I highly recommend getting a 64GB card, anything higher might cause issues. -One of the reviews said you couldn't set the screen to display mph or 12 hour time. I was able to set both, either they fixed it via a firmware update and the new ones are updated or some people are just not tech savvy. -My SUV already had a OEM crappy backup camera, so I didn't spend time tapping into the reverse light. -There isn't a app to wireless transfer the recordings. So you have to plug the miniSD card into a computer. -Navigating the folders to the files are pretty intuitive. But if you need to have both the front and rear recordings playing at the same time, you'll need to download their GV Player. Which I will add as a Con below. -Excellent and responsive customer service. Just make sure you email service.wolfbox@gmail.com and not what's listed in the manual. Cons: -Firmware. No mention anywhere how to update the firmware. I'll reach out to support to add me to the email list when new firmware is available. -Speed warning setting. Can't change it from kph to mph, but a firmware update in the future could fix this. Not that big of a deal, since you will only have to set this once. -No automatic brightness adjustments. In modern cars when the headlights come on, the tachometer and infotainment would dim accordingly. But I can see how this could be a liability as well. -I use this as a normal mirror, but with the time/date and GPS overlay on it. I have noticed the glare issue others have noted - especially when it's overcast (even with all my windows tinted -except the front). But since I'm not using the rear camera live video feed 100% of the time, it doesn't bother me. I was more interested in the rear dash cam ability. -I wish there was a saturation/hue and contrast setting, maybe in a future firmware update. -The GV Player has a little bit of a learning curve, especially when there is no manual. The user interface is also dated. I also couldn't figure out how to get the GPS portion working in the software. ... show more

    • Mirror dashcam with backup camera
tldr: highly recommended pros - easy setup, standard jacks/charging, great quality, full screen. cons: slow(ish) startup, no fast auto-turn off option. This is the best Mirror Backup Camera I've owned so far. I've bought several in the $50-$60 range and they were okay, but this one beats them by a mile. Setup was easy - I was even able to re-use the previous cabling from my old backup camera which saves me an hour. They use the standard 4pin jack for the backup camera, so you can swap those out if they go bad or if you find a newer back cam with better quality. Uses USBc for charging which is nice as you can plug it in a regular usb outlet (I have a 4 usb outputs hub). Touch screen is good and responsive. Video output on the mirror can be full screen which is very nice. Quality is also great. My few negative notes would be that there's no option to set the image to go away quick. When I start the car, cam comes on and stays on for a whole minute if I don't manually turn it off. 1 minute is the smallest amount of time you can set for auto shut down. 10-15 sec would have been nice to have as an option as I don't want it on while driving. Startup time is slightly on the slower side (compared to other backup cams). Takes a solid ~7 seconds to start so if you're in a hurry - backup cam won't come up right away when you're backing up. I'd recommend this product without a doubt and will buy again if needed for a different vehicle. ... show more

    • Works Great in 1998 Ranger
Review Image by Ouroborus Ouroborus
As indicated in the headline, this was installed in a 1998 Ford Ranger. The installation was fairly straight forward and I was able to use existing grommets in the firewall and floorboard to exit the cab of the truck and run the wires to their destinations. The included 20-foot camera cable was just about the perfect length for my truck. The camera quality is great, I can easily make out the license plate information on vehicles that are captured in the video and images. The night vision is clear and easy to see. A caveat to the night vision is glare from headlights - headlights both oncoming and rear-approaching provide a significant amount of glare, enough to obfuscate the view and prevent making out finer details. I'm not sure a whole lot can be improved upon this, though. The included mirror/display easily attached to my existing rear view with a couple of elastic/rubber mounting bands and was quick and easy. The reverse mode is great, and gives clearly visible parking lines, which are customizable in the settings of the device. I thought that this feature to customize the width and depth of the reversing lines was extremely well thought out. The device boots up quickly, and is running within a few seconds of turning it on. The power draw seems minimal and if I forget to turn it off, it hasn't drained my battery yet (this can be prevented with a hardwire kit sold as an accessory for this device). My principal caveat is that the GPS is pretty inconsistent. I have the puck mounted in the window and there doesn't seem to be any rhyme or reason as to when the device is going to pick up adequate signal. Sometimes it works when it's cloudy, sometimes it doesn't. Sometimes it works when it's clear skies, sometimes it doesn't. I have found that if I toggle to video playback mode, then back to recording, the GPS generally comes to life. Rebooting, disconnecting the puck and reconnecting, all of the normal tricks and tips aren't nearly as reliable as toggling between playback and recording. ... show more
