WOLFBOX G840S 12" 4K Mirror Dash Cam with 5.8GHz WiFi, 2160P Full HD Smart Rearview Mirror for Cars & Trucks, Front and Rear Dual Cameras, Night Vision, Reverse Assist, Included 32GB Card & GPS

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.

I originally bought the Wolfbox dashcam as a security device as I always knew there was a risk of theft where I live in a busy urban area. My car is parked in the street every night. This is why I purchased a mirror dashcam as it has a lower profile than some others and could be mistaken for a mirror without closer inspection. However the dashcam is much more than just for security and is an extremely effective device for giving a wide forward and rear view of the road. The quality is excellent and the screen is large enough to have a split view of front and rear although I defaulted to rear view only most of the time. The quality of the recordings is very good and clear and there are options to choose the length of each video capture. It has the facility to record sound too although I have chosen not to use this. I had some issues with glare causing reflections in bright sunlight, however, I experimented with angles and found if I angled the screen upwards slightly I solved this problem. My only real criticism is that car headlights at night cause a starburst effect on the screen which causes the picture to be less clear. This was not a deal breaker for me, just a minor gripe (potentially with a solution - I will experiment more). One of the most amazing things about Wolfbox however is their exemplary customer service. They are incredibly attentive and helpful. When I asked about a hard wire kit so that I could leave the device on overnight they sent one free of charge immediately. Any queries I had were swiftly answered politely and clearly. I cannot recommend this company enough and the product is great too.

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.

This is a great product and relatively easy to install. The image quality is great. However, it appears that the version I've bought does not have a WiFi connection which makes it pretty redundant for me as I don't own a laptop to read the SD card. It was fitted to a VW Transporter so the rear camera needed an extension cable. Purchased in March 2025, looks like WIFi added from April 2025. Check with the supplier for the actual change. Update- I've purchased the latest version of the G840s as it's a first class product. Wolfbox have also been in touch to discuss my original review. The product was always 1st class but unless I could connect wirelessly then it would give me an issue. My van, now has a wireless connecting camera and it's spot on. Wolfbox have also offered to compensate towards the 1st camera bought, which was my mistake.

I recently installed the WOLFBOX G840S 12" 4K Mirror Dash Cam in my van, which has no rear windows, and it’s absolutely perfect. The front and rear cameras give me full coverage, and the 4K front + 1080P rear footage is crystal clear. The touch screen rearview mirror is easy to use and makes reversing and monitoring my surroundings simple. I also love the night vision, reverse assist, and the included GPS and 32GB card—everything I needed in one package. The 24H parking mode gives me peace of mind when the van is parked. Overall, this dash cam is an excellent solution for vans or vehicles without rear visibility. It’s reliable, high-quality, and makes driving and parking so much safer. Highly recommended!

Quality product,recomend..

Value for money,Best night vision and easy to tale backup and preview using app.

Great camera system. Easy to install. The instructions are very easy to follow. Works great. This is my second Wolfbox mirror dash camera. The first one I bought back in 2023 and fitted it myself. I sold that car that the first one was installed in and the new owners are very impressed and wanted it left in the vehicle.

Amazing dash cam and rearview mirror. Very easy to install cleanly, and made it easier to see through the back at night (especially when someone had their brights on behind me). Captured great quality video on both ends.

After years of buying inferior dashcams I thought this one would be another disappointment at that price point but how wrong I was. 2.5K and with a 1080P rear camera as well! Works brilliantly.
