    Thanks for another fantastic post. The place else could anyone get that type of info in such a perfect way of writing? I’ve a presentation subsequent week, and I’m on the look for such information.

    THank you so much. Can u provide some screenshots

    The G840 H model has a much better night mode video Front / Back, and changing the reverse lines is easier over the G840S that I also own. However, there are some tradeoffs on the G840H coming from the G840S which there shouldn’t be.For example:UPDATE ***FOR FIRMWARE DEC .28, 2020 (Kudos to Wolfbox for continuing to improve the camera features and functions through firmware updates 🙂 1) S version has split screen view / H model does not.*** 2) H version NOW HAS a real-time speedometer in the bottom left screen corner ( you can also select to have a Power Icon or Car with active camera view icon instead.*** 3) H version NOW HAS GPS coordinates stamped on the video when played back on PC . Would be best to have the GPS coordinates displayed on main screen in case of emergency.***4) H version NOW HAS the option to flip the rear camera image 180 degrees if you need to mount the rear cam on the bumper.There are some improvements on the H model over the S version. For example:1) The video is much clearer on the H model ** especially at night, because of the higher resolution camera over the S version.2) To change camera view on H model from Front-Back, you just swipe L-R or R-L / S version requires 2 button taps.3) Changing brightness on H model does not require an initial tap to bring up the slider /S version does.4) The H model has a better, simpler direction indicator.*** If they add the GPS coordinates readout back to the screen, It’d be a home run.In conclusion:I’ll stick with the better video/camera on the new H model. I AM NOW only disappointed in the missing split/screen option and lack of GPS coordinates displayed on main screen. *** This must be said about Wolfbox: I have communicated extensively with them over the past few months and every time they have been helpful, courteous, and prompt in their replies. They are hands down the best company I have done business with. Ever. A 4_3/4 Star product from a 5 Star company. 🙂

    This camera allows for enhanced viewing for driving in my van that had limited windows. The angle is wide and very clear. Has improved my safety driving.

  6. Amazon Customer

    Night vision is great, picture quality is very clear. Easy to use and reliable.

    Je viens de recevoir le G840HMais par contre la notice n’est pas en franЌais.Avez-vous une version de la notice en franЌaisCordialement

  8. D. Brown

    Bought this to use for traveling with our trailer. Easy to install. My truck has a Leer cap on the box, so the rear camera was mounted above the cap door. I bought the 33′ extension cable and it worked with 4′ extra. Picture from either camera is crisp and easy to use. Currently powered by the cable for the standard power plug but will be installing the optional power cable to use the parking mode. Wish there had been an option to substitute the longer cable, as the short one is no use to me for this application.

  9. Jayden D. Peete

    Works great, would recommend purchasing. I would say order brandnew as the refurbished version arrived with a broken back camera. Customer Service is great and was willing to go above and beyond with providing a new product to replace damage. I will follow up with review after the new unit is received.

  10. Dylan R.

    Not only is the camera quality above and beyond along with the touch screen quality, Wolfbox Direct had some of the nicest and fastest responding customer service I’ve ever dealt with. I sent them a message wondering if I could get a second camera for a trailer and once I fully explained myself they didn’t even hesitate to offer sending me another one. 5 star service and 5 star products, thank you!!

  11. Larry R Verble

    Perfect

  12. Robert Cwiklik

    Nice product overall. The only major flaw is that you cannot invert the image displayed. So just make sure you position the rear view camera correctly and check the feed BEFORE you mount it. This will save you some time and a headache.

  13. Miguel H.

    Tiene micr—fono interno por lo que vamos a poder ajustar si queremos o no que se grabe el sonido, del mismo modo que en los ajustes vamos a poder seleccionar el castellano como idioma. Si la instalaci—n la hemos realizado lo suficientemente bien, la realidad es que obtenemos unos resultados fabulosos y me ha parecido el sistema de seguridad mas interesante al mejor precio que podemos instalar para viajar este verano

  14. Mark

    The night vision is not so good. All lights flare really bad and its basically impossible to know what kind of car is behind you at night. Which was literally the purpose for me buying this since I have dark tint. Also I didn’t realize how outdated SD cards are. 3 desktops and 2 laptops in my house and none of them support SD cards. Well I might have to return it because I suppose nothing is actually recording until its formatted?

  15. Eugene

    I’ve had this mount for a little over a month now and it’s super great I’ve gone through three months before this and this is by far the best one yet. The pictures always so clear and well-defined large and easy to read. I use it as my review mirror. Highly recommend this.

  16. Larry L Thompson

    I purchased mine for a Class C RV. G840H rear view mirror/Monitor has nearly every feature I was looking for & at a great price considering the price of most advertised Class C RV systems. Plus, I simply didn’t want to give up any viewable area in front of me with a 7″+ monitor stuck on my dash between me & the road. I will likely get a higher end camera in the future but I’ll still be money ahead.

  17. JP

    The display is very crisp and bright, and the resulting front and rear camera footage is excellent.I was disappointed to find that there was no way to display GPS coordinates on-screen (nor are they stamped on the footage). There is GPS data in the .MP4 files, but no good way to display path or speed on a PC map. (If anyone is aware of a compatible dash cam movie/GPS map viewer, please let me know).There is also no provision for any “surveillance mode” (i.e., recording while parked), so FYI.One significant issue that I had was that the included USB cigarette lighter adapter that shipped with the dash cam became very (very!) hot after about ten minutes of use, causing the dash cam to reboot continuously until unplugged and cooled. If you’re going to buy this dash cam, BE SURE TO ALSO BUY AN APPROPRIATE HARDWIRE KIT!Other gripes:There’s no real manufacturer support site (nor web site, period), and the included documentation is very limited. I’d like to ensure that I have the latest firmware, but have no idea what the most current version is, or how to update the dash cam (although I’m sure it involves booting with the updated firmware installer on the micro SD card).Would I buy it again? Umm…maybe.

  18. MattWeiler

    I bought this for my wife’s car.I have a much older model from a different manufacture in my car, and this one makes me want to upgrade mine now :(The screen on this is almost the entire mirror, that is amazing.And the quality of the screen is very good.The camera’s, both front and back are very clear and the rear camera housing being metal is a major plus.The only part of installing this that is difficult is maybe the wiring of the rear camera (depending on your car) and getting the wire out the back of the car near the license plate (again, depending on your car).

  19. Peter Todary

    This is not the first dashcam I owned. I originally had the vantop 609 and it was alright. The night vision though was absolutely awful and I drive a lot in the night because I come home late. I got this one and was blown away by the quality difference. Get this one. The camera quality is top tier and truly has night vision and very minor sun gear

  28. Naomi

    Overall happy with the product. It is easy to install with little mechanical skills. I do like that you have a front and rear dash cam as well as a reverse camera. The display quality in the mirror itself is pretty good as well. There a few things that I would like to see updated on the newer versions of this system.1. An anti glare screen on the mirror display.2. A more sleek/smaller reverse camera housing.3. A more zoomed out reverse camera so you can see more behind you when reversing.4. A more stiff/sturdy (maybe even locking) adjustable rear camera mount. I find that the rear cam needs to be readjusted every once in a while since the angle is only held in place by 2 very small screws. (I used locktight on mine to hold them in place but they still move a little bit.)I would highly recommend getting the hardwiring kit for parking monitoring. I was sent the wrong fuse with mine so I had to go out and by my own fuse taps to make it work.

  31. George Wood

    When I received this product I was impressed with the quality. After installing it I was pleased with the operation but it was missing some of the features that I saw in the video that I had seen on you tube. I contacted Wolf Box and they explained the changes made in models and offered me an upgrade to download which I did and it worked very well and was very simple to do. After I had this for about a month I decided that I wanted to add an extention and a second camera for my RV so II contacted Wolf Box to purchase a second camera and extension. They were very helpful and sent me a camera and extention that I will be installing very soon. Overall Wolf Box has been very professional and helpful in making sure I am pleased with this item. I recommend them highly. Thank you Wolf Box.

     Please be responsible while using this product, another screen on the car can be really distracting specially when trying to figure out all this new toy can do.Installation is pretty straightforward, thinking of getting a second one for another vehicle…Good:-Easy to see during the day-Mirror is good enough when display is off-Installation is fairly easy ( skill level 2 of 5)-Quality at night is pretty goodBad-Unit is heavy, if your mirror base is not strong enough this will cause it to move or face down while driving-Quality on mirror display is not great ( but it does the job)-Auto off feature seems to be buggy, mine stays on after shutting the car off (yes I played with the settings nothing changed) not a deal breaker

  35. Jenny Sadowski

    Over the rearview is nice. The front camera you manually move left and right up and down is done with the screen. I have it set to Auto off so it’s still acts as a rear view mirror and I can see reflection from behind me. It does shake a little bit when I’m looking at it as a rear view mirror and it’s kind of annoying but I can definitely deal with it. Still need to set up the backup camera but waiting for warmer days.

  36. Giuseppe S

    Looks great, customer of mines get impressed from realizing it’s a back up camera not a rear view mirror. Audio works well for the interior. Love that you can move the camera from up high to down low and an easy switch from rear to front from a swipe of the finger to the side. Only thing I’d prefer if my truck was able to have it set up on all night and have a big enough storage for memory.

  37. Ben heyne

    It is a nice product.

  38. Amazon Customer

    Having a camera at the front and rear is great but this dash cam mirror does have it’s drawbacks.. First, the installation is easy enough but unless you plan on hard wiring it, it’s a pain to plug in and un plug constantly. Second, the rear camera quality is .. ok , but nothing compared to my (and most peoples) actual vision so I am very aware I am watching a screen and not a reflection. Although the stream is live, the fps is not as fluid as I would like. Finally, the view you get is from a viewpoint very foreign so it takes some getting used to.. All and all, It has alot of potential but has a ways to go before I would trust it with my life.

  43. llargo

    Great product. Once you get past the learning curve.Instructions are minimal. Had to do research online and through YouTube in order to figure out how BEST to run wires. My car was actually hit by another car during the month I was trying to figure out how to install this. In this crowded,modern,letigous era this is a verified non-biased witness. Makes me more mindful of own driving.

  44. Peter Su

    Awesome mirror awesome camera and most of all awesome customer service! I will break this up into two parts of the review one part about the product, and another about the customer service.The product is solid. It is great and it works. It works very fast and easy touchscreen is very sensitive. I was worried that it would be slow and not responsive. Like the other reviews, the product is very good, comes with everything you need. I had a long pick up truck, so I needed to get the extension cord.As wonderful as a product is, I did have issues during my install. I contacted customer support, and they really stood behind their product. The reply time was very fast, and they really took care of my situation. They definitely went above and beyond what any other Amazon seller would typically do. I would highly recommend anything the seller would sell. The product is also wonderful. I must have for your car.

  51. Sue – Ontario

    Ordered for my son’s F150 (2010). Bright, clear image quality. Suggest getting the extension kit if installing on a pick up. If ordering the extension kit or the hardwire kit make sure it matches the model. We have the G240h, but in the “frequently bought together’ area, it lists the kits for a different model (G240s). This was an issue for me, but the seller was very responsive, and were quick to help rectify.

  52. Jitesh R.

    I’ve bought a $40 before buying this one, and the quality of the video in the darkness is super high compared to others, I’ve kept the display always own so I can see my back-up camera while driving and turn off the display and use the screen reflection and use it like a mirror.

  53. Amazon Customer

    Great little camera

  54. Tyler

    Camera was super easy to install… less then 40 min.. amazing picture awesome interface. Only thing I wish there was a website to download the latest firmware to take full advantage of the on-board GPS more to follow as soon as the company emails me back with the link for the update firmware

  55. Brandon

    I would say that this is a must-have in any car that doesn’t have a backup camera. The video is crystal clear from both the front and rearview cameras and the installation wasn’t hard to do at all. I followed the instructions in the box but there are also tutorials online if you’re having trouble with that. So far from using it for 3 months, I haven’t encountered any issues.

  56. Wonder Woman “Julie”

    I really like this mirror cam, great quality and back camera is nice. I have had the camera shut off a couple of times while riding and not come on one time when starting the car. Easy to operate once you get the hang of replay.

Very happy with the video resolution, and recording of both rear and front camera at the same time . I went with the hard wire kit . ItÕs not to bad to install , takes a bit of electrical knowledge.I had to contact seller as the rear camera cord was not long enough. They were happy to send me a longer 33Õ cable . Customer service was amazing.I would definitely buy this camera again , I like the fact that it is always recording. Will update review after a few months .

    The camera quality for the cameras are pretty good. However, the rear camera is pretty useless in the dark. I have three problems:1. The 32GB SD Card that comes with it started producing a read/write errors within the first week, so recording won’t work unless I replace it. I get that SD Cards will inevitably fail when continuously recording, but having it crap out in the first few days is a real bummer.2. The device occasionally stops turning on. The fix for that is just leaving it unplugged for a few hours before it will turn back on.3. There is no option to flip the image for the rear camera.I ended up just uninstalling it. It’s great when it works, but pointless when it doesn’t. Can’t honestly recommend this, but I’m sure majority of buyers will be happy with it.

  67. JR

    Great video quality and build quality. I love the rearview cameras form figure. It looks a lot more sleaker than most rear view cameras that come with other dashcam mirrors and in general rearview cameras…HOWEVER…I’m confused…This new model is missing things that the old one had that was super useful.No more speed read out both on the mirror or on recorded files. Same goes with the GPS coordinates. That pretty much makes the gps feature useless…yes it tells you what direction your traveling but honestly that’s not very useful. The thing is, when you pop into the gps menu that information is being collected. So this is simply a UX decision they made to not actually display.Also, the user interface on the older model I find more intuitive as far as when you want to filter and view your videos.Another little missing feature in the new model that the old one had. you could actually specify your preferred flicker rate. This model doesn’t have that.Shoot, this sound more like a review for the old model vs the new…But again, the new model’s camera is definitely NOTICEABLY better…if you don’t care for the stuff I mentioned thats missing, definitely get this.I will be returning it for a different brand, but that’s more so because of the features I mentioned that are gone.

    Overall this a very decent product as this is my third one. So far this is the best out of the three brands. My only issue is when the night vision kicks in the picture gets very grainy. During the day or when there is plenty of light at night, both cameras are very clear and picture is sharp. Low light conditions not so much

  70. Hart

    This camera system is a lot more money than most but there is a lot to like about it and includes some things that are missing or there’s a cost to add on the additional items with other similar camera systems. For instance, most of the newer more advanced cameras are capable of tying in a GPS antenna but it’s not included whereas this kit comes with it.There are two main things to consider with this kind of camera system, mounting and video quality.First off mounting:Since this is designed to fit over top of the existing rear-view mirror it can be a little tricky to install. On a GM truck for instance where the mirror includes GM’s OnStar system the mirror is deeper and makes the silicone straps used here really stretch in order attach the camera. Then there’s a bit of fiddling and aligning that’s needed as dontchaknowit, the resident mirror isn’t completely flat. In all, it took about 10 minutes to get this set up properly. On v3ehicles where the mirror is just that, a mirror, like our KIA this was very quick and easy to install since the mirror is nowhere near as deep as the GM’s._ As the lens is on one end it needs to be placed so that it isn’t covered by the cars mirror. It also swivels to accommodate the angle at which the rearview mirror is sitting so that the driver can properly see what’s going on behind them. It takes a little playing to get this set just right as well but keep in mind that if the vehicle is being driven by two people that are significantly different height-wise and each will adjust the mirror it will have a slight effect on the lens angle and what gets recorded.Running the power, GPS antenna, and rearview camera cables can be a little tricky as well if the end result is going to look good. For me it meant slightly popping off some interior flashing, sliding the cable behind it, and securing everything again without catching any of the cables.The GPS antenna works best when mounted on an exterior surface but this can be tricky and include a lot more work than I wanted to get into. I was able to place it under the dash so the right side was facing up and had it located so there was no metal above it. We install a lot of GPS tracking devices this way so I knew it would work fine and it has been accurate for several weeks now. One thing to note, if you do this don’t place anything metal on the dash (think an aluminum clipboard for instance) or even a Doritos chip bag as the shiny interior is metal that blocks GPS and radio signals.The camera cable was the most difficult to run. It needed to be placed under the carpeting, run around various protrusions from seat and such, and then tucked behind panels. Once it was run into the truck area it was simple enough to hide it behind the liner but we did have to drill a hole large enough to pass the cables connector through it and then seal it up with a grommet and silicone. Once in place and fastened with screws it will stay in place._ There is one thing to consider when placing the rear camera on the bumper or license plate holder, any spray from rain or snow will collect on it and then at times make it almost useless._ If the rearview camera is placed inside so it faces out the back window it will stay clean but when snow, slush, or dust covers the back window this will affect how well it can work._ There is no perfect place for a rearview camera.Video performance:Both the front-facing and rearview cameras offer great imagery. The front-facing is the best I’ve seen so far the rear is equal to what the more expensive versions use for front-facing._ Nighttime viewing is excellent._ The frame rate is fast enough to keep recorded video looking smooth when playing back.Since the camera will work with TF cards up to 128GB it can store a fair bit of recording but keep in mind that at 1440 it uses more memory for the same amount of drive time than cameras with only 1080P resolution.Others:What I really like here is the operating system used. Most dash cams use a common system and it’s desperately lacking. Here the proprietary system is much easier to set up and navigate through. There are a lot of options so it took a couple of minutes to get set up the way I wanted it.The mirror portion of the camera is also very nice, it’s clear and doesn’t distort at all. When viewing the camera(s) on it everything is clear.Being able to see where I am via the GPS screen is ok but really of little use in day to day life. Where the GPS information comes in handy is when something happens out on a highway where there are no street signs and the video may be needed to provide evidence.

    This camera system is a lot more money than most but there is a lot to like about it and includes some things that are missing or there’s a cost to add on the additional items with other similar camera systems. For instance, most of the newer more advanced cameras are capable of tying in a GPS antenna but it’s not included whereas this kit comes with it.There are two main things to consider with this kind of camera system, mounting and video quality.First off mounting:Since this is designed to fit over top of the existing rear-view mirror it can be a little tricky to install. On a GM truck for instance where the mirror includes GM’s OnStar system the mirror is deeper and makes the silicone straps used here really stretch in order attach the camera. Then there’s a bit of fiddling and aligning that’s needed as dontchaknowit, the resident mirror isn’t completely flat. In all, it took about 10 minutes to get this set up properly. On v3ehicles where the mirror is just that, a mirror, like our KIA this was very quick and easy to install since the mirror is nowhere near as deep as the GM’s._ As the lens is on one end it needs to be placed so that it isn’t covered by the cars mirror. It also swivels to accommodate the angle at which the rearview mirror is sitting so that the driver can properly see what’s going on behind them. It takes a little playing to get this set just right as well but keep in mind that if the vehicle is being driven by two people that are significantly different height-wise and each will adjust the mirror it will have a slight effect on the lens angle and what gets recorded.Running the power, GPS antenna, and rearview camera cables can be a little tricky as well if the end result is going to look good. For me it meant slightly popping off some interior flashing, sliding the cable behind it, and securing everything again without catching any of the cables.The GPS antenna works best when mounted on an exterior surface but this can be tricky and include a lot more work than I wanted to get into. I was able to place it under the dash so the right side was facing up and had it located so there was no metal above it. We install a lot of GPS tracking devices this way so I knew it would work fine and it has been accurate for several weeks now. One thing to note, if you do this don’t place anything metal on the dash (think an aluminum clipboard for instance) or even a Doritos chip bag as the shiny interior is metal that blocks GPS and radio signals.The camera cable was the most difficult to run. It needed to be placed under the carpeting, run around various protrusions from seat and such, and then tucked behind panels. Once it was run into the truck area it was simple enough to hide it behind the liner but we did have to drill a hole large enough to pass the cables connector through it and then seal it up with a grommet and silicone. Once in place and fastened with screws it will stay in place._ There is one thing to consider when placing the rear camera on the bumper or license plate holder, any spray from rain or snow will collect on it and then at times make it almost useless._ If the rearview camera is placed inside so it faces out the back window it will stay clean but when snow, slush, or dust covers the back window this will affect how well it can work._ There is no perfect place for a rearview camera.Video performance:Both the front-facing and rearview cameras offer great imagery. The front-facing is the best I’ve seen so far the rear is equal to what the more expensive versions use for front-facing._ Nighttime viewing is excellent._ The frame rate is fast enough to keep recorded video looking smooth when playing back.Since the camera will work with TF cards up to 128GB it can store a fair bit of recording but keep in mind that at 1440 it uses more memory for the same amount of drive time than cameras with only 1080P resolution.Others:What I really like here is the operating system used. Most dash cams use a common system and it’s desperately lacking. Here the proprietary system is much easier to set up and navigate through. There are a lot of options so it took a couple of minutes to get set up the way I wanted it.The mirror portion of the camera is also very nice, it’s clear and doesn’t distort at all. When viewing the camera(s) on it everything is clear.Being able to see where I am via the GPS screen is ok but really of little use in day to day life.

     I had one like this before but it had some defects so I had to buy it again. I especially like this type of camera because it works both as a camera and mirror and you don’t have to hang a separate camera with the mirror.It is an easy installation with all the kit comes with it. The screen is really big of 12″ and gives a perfect vision. There comes a 32 GB TF card for memory and rear camera too with all the wires and cables for installation and functioning.It does its job pretty well. It has 2.5k dual-lens streaming media which was not there with my previous one. The picture quality is awesome. Catches every moment very sharply with both front and rear cameras and records there in it. The night vision works well, no problem is catching night moments like day ones. It is a touch screen device easy to operate with multiple functions.Even there ia parking assistance and GPS.

    I gotten quite a lot of attention with this dashcam, it blends in good with the interior of the car so much that people think the car came with it. The resolution is great for capturing small details like license plates and it performs well at night also. Just make sure to keep the windows nice and clean to reduce reflections or glare. It also has a built in compass which is good since my car does not have one and I find this feature helpful.

    Installed this in my wifes daily driver car to test it out; the screen is very large and it can work as a reverse camera and a “active rearview” camera. However this is a different dynamic then most people are used to and the camera doesn’t exactly see the same way that you would see using it as a rearview.Therefore if you are covering up your rear view mirror with this (the way that it is meant really to be installed) then it will change how you drive. Also if you live in a place like south florida and you don’t have tints then the screen could be harder to see on a bright day (however the screen is pretty bright).All in all the recording quality and night vision quality is good but coming from traditional dash cams it takes time to understand.Personally I think its better for older vehicles while newer vehicles should have regular dash cams.All in all its a good product as long as you know what you are buying.

    SD card has been inserted into the machine, which is very convenient. They treat every detail with great care, and the rear lens is even like a work of art. With complete functions, the reversing line can be manually adjusted when reversing, which is very novel and practical. The front and rear shots are very clear, and 1440P Front and 1080P Rear Full HD Dashcam are very enough for a car dashcam. Really easy to install the front camera, but the back camera is a little bit hard if you what to connect with your car backlight.

    Worth Waiting, Really recommend!I own a WOLFBOX G840S mirror dash cam, which is a gift send by my friend. Since the new version G840H is come out, I’m exited to use it. It take nearly a months to receive, but it’s totally worth waiting.The front and rear lenses all show very very clearer pictures. Even at night, you can see the front license plate of the moving vehicle clearly. When you are reversing, the four corners of the reverse assist line can be manually adjusted. If you want to record a video urgently, you can double-tap the screen manually. This feature is really great!! I like this upgraded dashcam.

    Easy turn on and great quality. My old mirror dash cam was only left corner of my mirror so this is a huge step up. I have yet to install it but IÕm excited just based off of the great quality IÕve seen already! The fact that it give you the option of a front view as well as the rear allows you to be protected in both viewing directions.

    This is the mirror dash cam I am looking for. The cam size is right for my car, the 12″ screen is big, fit right on to my original rear mirror, and it’s not blocking my sight. My husband and I are very happy with it. It’s easy to install, just follow the manual instruction. Perfect and worth buying.

    It’s my opinion that everyone should have a dash cam. Not only for insurance purposes but also for personal and community safety (i.e. as a “digital witness” to road crimes and accidents).Dash cams come in a variety of styles, including dash-mounted, windshield-mounted, external, and mirror-mounted. This particular kit from Wolfbox includes both a mirror-mounted front camera and a rear camera that can be mounted inside or outside of your vehicle.Included in the kit are various mounting hardware and double-sided tape for mounting. You also get a high-speed 32gb microSD card (nice bonus!), a GPS unit (this is optional and you don’t have to use it), a USB car adapter, instruction manual, and mounting straps for the mirror.All of the included cables are long enough to use with just about any personal vehicle, especially for the rear camera. On a side note, the rear camera can also be hooked up into your reverse lights, so when a reverse signal is detected, the back-up camera mode with a distance guide will be activated automatically. This is an optional step, but it’s a great feature to have and it’s not difficult to do.The mirror camera mounts over your rear-view mirror, and the included straps make it pretty universal. The mirror’s reflection is tinted, similar to your standard rear-view mirror when you’ve switched to the night-driving configuration. I don’t personally love a dimmed mirror during the day, but it does reflect enough to be useful on its own (i.e. without the camera screen).With the exception of the screen on/off button, all your controls are on-screen through taps and swipes. The interface is intuitive, however, you can’t enter the settings screen without stopping the recording, which isn’t a huge problem, but it starts recording every time it’s in the main screen so it gets annoying.The settings screen offers some basic settings like audio recording on/off, g-force sensor sensitivity, etc. While there is an option to select the resolution of each camera, it defaults to the native resolution of each camera (2.5k or 1080p) without any option to change it. Not really a big deal, since these should be kept at their highest resolution, but then why not just remove the option?The GPS info screen is really cool and it shows your GPS signal quality.The unit has an option to stay on as a parking camera, but it requires an optional hardwire kit which is not included in this bundle.While you do have the option to “auto on” or “auto off” the screen, the auto off function works on a delay, so you will ALWAYS see the camera screen for a short while before it turns off. This is actually problematic as it should be OFF all the time with this setting enabled as I’ve found myself several times struggling to see clearly what’s behind me as the screen + mirror reflection combined = very poor visibility. And this is probably where the main weakness of this unit lies. The screen, even at full brightness, is not easy to see in bright daylight and the dimmed mirror means you get a poor view of what’s behind you.The recorded video and audio quality from the front camera are excellent. Even when pausing to see the license plates of vehicles heading towards me, the image is clear and very easy to read. The rear camera, while it does shoot at 1080p resolution, is a poor-quality 1080p. Just for comparison sake, my typical dashcam records at 1080p and the quality looks much closer to the 2.5K front camera of this system and puts the rear camera quality to shame. That said, the rear and front cameras are nice and wide and they do capture everything you’d need in the event that video evidence is required.Both day and night time recordings are good. I wouldn’t say that the HDR on the front camera is spectacular (i.e. clouds will be blown completely white in many cases), but it does an excellent job with everything at car level, which is most important.Playback is a little clumsy. On other mirror dashcams with both front and rear recording, you can often see both the front and rear recordings simultaneously, which is extremely useful. This system, unfortunately, saves the front and rear recordings separately and in two different folders, so viewing them needs to be done separately.Viewing from the microSD card to a PC or mobile phone is straightforward and I had no compatibility issues with either. You can lock videos from the dashcam screen, which will put it into a separate folder that will not be deleted or overwritten by the camera.Overall, I think this is a really good dash cam system. It offers a very good front camera and acceptable rear camera performance, with a recorded format that is easy to access. It’s a shame that the driving experience is a little clumsy due to the below-average mirror performance and poor screen visibility during the day. I do appreciate how easy the install was and how useful this system can be overall.

     The G840 H model has a much better night mode video Front / Back, and changing the reverse lines is easier over the G840S that I also own. However, there are some tradeoffs on the G840H coming from the G840S which there shouldn’t be.For example:UPDATE ***FOR FIRMWARE DEC .28, 2020 (Kudos to Wolfbox for continuing to improve the camera features and functions through firmware updates 🙂 1) S version has split screen view / H model does not.*** 2) H version NOW HAS a real-time speedometer in the bottom left screen corner ( you can also select to have a Power Icon or Car with active camera view icon instead.*** 3) H version NOW HAS GPS coordinates stamped on the video when played back on PC . Would be best to have the GPS coordinates displayed on main screen in case of emergency.***4) H version NOW HAS the option to flip the rear camera image 180 degrees if you need to mount the rear cam on the bumper.There are some improvements on the H model over the S version. For example:1) The video is much clearer on the H model ** especially at night, because of the higher resolution camera over the S version.2) To change camera view on H model from Front-Back, you just swipe L-R or R-L / S version requires 2 button taps.3) Changing brightness on H model does not require an initial tap to bring up the slider /S version does.4) The H model has a better, simpler direction indicator.*** If they add the GPS coordinates readout back to the screen, It’d be a home run.In conclusion:I’ll stick with the better video/camera on the new H model. I AM NOW only disappointed in the missing split/screen option and lack of GPS coordinates displayed on main screen. *** This must be said about Wolfbox: I have communicated extensively with them over the past few months and every time they have been helpful, courteous, and prompt in their replies. They are hands down the best company I have done business with. Ever. A 4_3/4 Star product from a 5 Star company. 🙂
