Review: Excellent Mirror Dash Cam - This mirror dash camera is amazing. I think I've converted everyone in my family to buy one. I've ordered 3 myself and family has also ordered. Excellent video playback, clear and visible, not grainy at all. Really easy to use. Has a few different settings, for my child I put on the speed alerts, that kept them aware, especially since a lot of the roads are average speed near us. Can be hardwired for continuous recording. Had them fitted by a professional but it can easily be done by yourself. Rear camera comes in use when reverse parking and even when someone hit my car from behind, provided excellent footage which shows fault. Has a save function so even if you write over the memory card, the video and pictures you save are still there. The customer service they provide is flawless, any time I've asked any questions, I get a detailed response. Cannot fault it at all.
Review: 2 Reviews in one - G840H and G840S - There are two reviews here. G840S & G840H =============================================================== Review for G840S: Although initially I though the device is quite bulky, after installation and setup I quickly changed my mind. I had doubts that the device will 'fit' my mirror but once again I was wrong. Just after few seconds of moving it around it fit perfectly and I was stunned how securely it holds. Installation: one important thing to remember is that the camera is on one side of the device as such the device itself will slide more to one of the sides of your mirror. Initially I thought that this will bring the 'picture' too close to my face, but actually it feels very natural and comfortable. Video: I have different 4k camera in another vehicle and after few days of driving and comparing the quality it is hard distinguish the difference. Needless to say, I spent a lot of time doing my research before the purchase, so when this one landed on my lap I was surprised with this shot in the dark. Box: the box comes with a number of gadgets that you can but don't have to use. 1) Beside the camera itself and the mounts, you can use the GPS device. This is not compulsory, but if you want the GPS/speedometer info, it’s a must. The add on is very small, consequently you can conveniently install it behind the mirror. From driver's perspective you won't see it at all and it won't impact your vision. 2) The other device is the reverse camera that captures picture in the industry standard (for reverse cameras) of 1080p. Initially I thought that the 140 angle on reverse camera (170 front) is insufficient but after driving a few days, I can confirm it's perfect. After reviewing videos I have no problems reading number plates, so in the case of unfortunate accident, you can stay assured, the evidence will be there. 3) Cloth, nice bonus for cleaning the camera or device itself 4) Plastic wedge to feed and hide the cable during installation 5) Few cable holders (there are doing just fine during hot day). Also they can be used multiple times so if you decide to swap the cable (during hardwire installation) this can be done easily. Before installing one or few make sure you are confident if your choice as they hold very well. 6) Power adapter 7) Instructions Build quality: The device feels nice in hand. You get the premium feeling and after opening the box, I almost felt like it's Christmas. Pros: Material, Quality, Ease of installation Cons: this one is difficult. NONE in short, but if I was to try and find one thing I don't like, well... not for me but the reverse camera cannot be mounted directly on the window. I know there are people who would prefer do it. Consequently its a matter of preference I guess. Would be nice to have an option to chose which reverse camera option you prefer... but I'm nitpicking now. =============================================================== Review for G840H: It pleases me to be given opportunity to once again test another product of this company. A frind of mine was recently involved in a car accident and regrets not having one. Cutting to the chase just like G840S, the G840H provides you with the same quality feeling. The reverse camera feels heavy, but it must be due to its very good build quality. I have seen some plastic reverse cameras which I would not risk putting outside of the car, but this one, without a doubt in my mind can be easily installed over your number plate and configured with the DashCam to be your reverse prinking camera. The box comes with everything you need to do the initial installation. If you need the 24/7 parking mode enabled, a hardwire kit is required. This is standard across the industry. The hardwire kit is not expensive and you can get a good one for areound £25. Picture quality: The camera records in 1440P and can be configured in settings to use either H.264 or H.265 compression. On the paper, 265 is better as offers better compression and more footage on the same memory card. In my private opinion I prefer the old H.264. I found it provides marginally better quality picture and the loss in form of bigger video files is the price I'm prepared to pay. Let's be honest, the 256GB cards are not that expensive these days. Reverse camera records at 1080P which is industry standard. Front and back camera angle coverage: Front record at 170 and captures nicely everything you need, even vehicles that are practically parked next to you. Back camera provides 140 degrees angle and this is everything you will ever need. There is currently nothing with wider angle or better quality from what I can see, but you are welcome to do your research. Memory card: The box comes with 32GB memory card. This is perfect to get the DashCam up and running straight away, nevertheless I do recommend upgrading to at least 128GB, or 256GB if you plan on using parking more. Installation: This cannot be any simpler. If you don't count the time to plug it into the power source, I doubt it will take you more than 30 seconds to get in installed. It's hard to describe it, but my advise it to simply put it over the mirror and wiggle around until you feel it sits comfortably, and then secure with straps. Settings: The camera has a huge screen and it is super easy to configure from software perspective. I do prefer this over cameras that need to be connected to over iOS/Android system. It is super responsive and provides immediate feedback. Box: Comes with everything you will need to get the device up and running. I have attached picture with items available in the G840H box. Pros: Just like G840H, the product is of premium quality. Also, if you like to see clearly what is behind you and could use a bit of zoom, think no more. The dash cam screen is big enough to provide you just that, and not big to make you feel like it covers the windscreen. Further to the above the cam comes with GPS so it can also record your speed and location. This is a huge advantage in case you have an unfortunate encounter and someone refuses to accept liability. Cons: This is more of preference. Although the 1440P video is perfectly sufficient to read the numberplates and to be used as evidence, I do prefer the 4k quality cams. If this is also your preference G840S from the same seller ticks all the boxes.

## Questions & Answers

**Q: Is there a way to protect a recording from being deleted if something happens**
A: You can lock these files.
It can be done via the small lock button on the screen.

**Q: Where do i put the red cable that is attached to the camera end of the reverse camera? Its just a wire with no attachment on the end**
A: Thanks for contacting.
You can connect the red wire of the rear cable to the positive pole of your car's reversing light, then it will show reversing line when you reverse. You can leave the red wire there if your car ahs its own reversing system
Hope my answer is useful to you.
If there is anything we can help with, please let us know.
Have a nice day!
Wolfbox

**Q: Made in China?**
A: Yes I believe it is. My auto electrician thought the cameras were high quality.

**Q: Is there an option to mount this without using the rubber bands - to use the existing rear mirror mount instead and remove the existing mirror??**
A: Hi,It's better not. Our mirror dash cam doesn't have a bracket and needs to be fixed with rubber straps. Thank you.

### ⭐⭐⭐⭐ Decent
*by Z***N on 4 January 2026*

Pretty decent mirror dash cam. Ive upgraded from a bog standard front one to a front and rear. Easy to install and pleanty of cable length to have round the top or bottom of car (especially the rear camera) rear camera easy to install and discreet in the back. I havent used the parking sensors as my car already has this. The functions and settings are easy to use as well as the app. I bought a higher memory sd card but it comes up with an error so unsure of why this is. Would be nice to be able to get a bigger memory sd card than the standard size you get. Only niggles really is that you cant minimise the cameras on the mirror. You can have either one cam fully or half and half of front and rear but cant minimise to small boxes (would be a nice feature) and to delete footage from the app its a pain as you have to turn WiFi on at the dash cam and connect your phone and then go into the app (only one dash cam is on as well) would be better if you can access without all thos faffing about. All in all its nice quality, 4k picture so clear and crisp. Would defo reccomend especially with added features with GPS ect. These are great to have for safety on the road.
