A great dash cam with some minor issues
This is the best dash cams I've owned the quality of the video and ease of use is pretty darn good. ease of installation is really dependent on the type of vehicle you own and the type of installation you want to do. Do you want all the wires neatly tucked away and hidden or do you want to use the sticky cable retention pieces that are in the box and make it easier. And obviously you can always pay a professional to install. I have three things that I would like to see improved on newer models / 2.0 1. The power button needs to have some kind of isolating rubber around it or be fixed in place. I have 2 different units and all both of them the button vibrates if the road is rough and gets picked up by the two microphones that are on both sides of the power button. The fix is just put a piece of tape over the power button not tight enough to depress it but enough to stop it from moving around. Wolfbox customer service sent me a replacement unit but it did the same thing the power button is a little loose and gets picked up by the microphones. 2. Wolfbox phone app, I have Android so I can't speak to the experience on iOS however for some reason it doesn't allow me to edit the video in the software it keeps saying that this function is not supported when I go to save. It also creates two file locations. one file of the video will be found in the wolfbox app, another one in my Google photos file. However I can't access the Google photos one as it is blank and says cannot be played until I delete the one in the wolfbox app then the one in the Google photos app works fine and can be played then. If I delete the one in the Google photos app first it deletes the one in the wolfbox app kind of confusing but I figured it out. Also sometimes playback in the wolfbox app is laggy. 3. This isn't in regards to the camera specifically but to the OEM wolfbox mounts. I have the Jeep one but reading reviews the one that attaches to the window Puck does the same thing. The plastic is pretty thin that mounts to the back of the camera unit it allows vibration into the unit and that can slightly be seen on playback. Overall this is the best camera system I've used it's really nice.. I know some of the stuff I say to the above is some nitpicks I also would like to see the 10-in have the OEM Mount support. I have a 12-in unit and in a jeep my sun visors will hit the unit because it's so wide. I probably would have purchased the 10-in fir the jeep if it could be mounted to the OEM brackets from Wolfbox but for some reason they cannot. I would definitely buy again I've already bought two of them hopefully in a revision they fixed some of the minor issues that I have come across. I also like to see the tri camera unut not be so expensive I really would have liked to get the tri bumper but not for an extra $250 and all it's adding is one camera the front bumper. Also in closing I've been in contact with wolfbox customer service support. Their customer service is probably some of the best I've ever experienced they reply on weekends during the night during the day like they must have somebody on 24-hour customer support. They provided possible solutions to the issues. Some of the suggestions work some of them did not however the unit is still an amazing dash cam it's aesthetically pleasing and an extremely well-functional.

Worth every penny
I have to say, Wolfbox never came onto my radar until I bought this thing. I love the functionality of it. I love the very high definition front camera, shooting at 4K, you can tell the exact make and model car, you can read the license plate. Even at low light/night driving. Also, some of my vehicles don't have the best visibility from the rear mirror. This thing has a stand-alone rear camera that you can mount inside or outside the car. In my opinion, this is one of the best upgrades you can get for your car. Also, it's not as expensive as I would expect this to be. Great product. Highly recommended.

Wolfbox 840S dash cam
I have used the dash cam for about a week and this is what I found: It was easy to install over my existing mirror of course we installed the rear camera ourselves and it wasn’t to difficult I have a mini cooper convertible and it installed just fine with the licenses plate attachment. The quality is good on front camera but the rear camera works Beautiful except for at night when its really dark and not many street lights the video is grainy but re-adjust itself when there are street lights. On the rear video the headlights from other cars I cannot see the car behind me or read the license plate the lights blind the camera only when the car is close sometimes at a distance its not to bad but not good. I don’t know if there is an another rear camera I could purchase to replace just that one with better quality. The reason I purchased the dash cam in the first place was for the rear camera for my convertible because my top sits on top of my trunk or boot I cannot see the cars behind me again (this was my purpose of buying the dash cam) during the day its great its only at night and just for future I think a front facing camera would be good also I am used to seeing myself in the rear view mirror and I forgot to mention that there is a glare in the rear view mirror when my top is down and its hard to see the rear view mirror I read the reviews on the glare cover and they weren’t that good. I can live with that but having a hard time with the headlight blindness from the rear camera when cars are behind me at night. I will come back and attach a video or snapshot to show you what I mean. Overall the dash cam isn’t bad I may need to spend more to get more I guess. I don’t know for sure but if I could upgrade just the rear camera for better quality for now, so I would not have to rewire everything that would great.

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.

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.
