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 / 2.01. 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.

5 stars… and with a couple of reservations
First of all, this product is and does exactly what they claim it does. The 12″ view display is VERY sharp and clear (with a couple of reservations I will address later), the wide angle lenses show everything and more, the GPS is accurate, and the rear-facing camera works very well, especially if you hook up the wire to the backup light so the unit displays the (adjustable) backup lines. Very useful in parking lots! The variety of settings and adjustments are impressive and useful. All-in-all, a really nice product.Now… here’s some things I feel you should know…. First, I’m no expert in dashcams. I actually tried an inexpensive windshield mounted one, and it was okay, but I thought it used up too much windshield “square footage” and was a little distracting next to the rear view mirror – the only place I could fit it. Which led me to the units that fit on the existing rearview mirror. MUCH better for what I wanted.I originally just wanted the forward-looking camera and resulting recording, but the GPS was so easy to install, so I did that. Then, after some thought, I wanted to install the rear-looking camera. If you have a sedan with a trunk, this will be very easy. I don’t have that. I have a 2009 Ford Escape, a smallish SUV style with a full hatchback as well as a window that opens. Lots of pivot points and moving parts. To get to the license plate light (the recommended routing and placement for the camera), I would have to nearly destroy the inside plastic panel covering the tailgate to route the wiring. And there was no good place inside the glass. So where? It ended up on the outside top driver’s side corner of the hatch in line with the luggage rack frame – for a little protection. Not happy with that, but it works, and it’s not the manufacturer’s fault. Just beware if you have something other than a sedan. You may have to get creative.Another issue is nighttime rear view. The flare from the camera at night is fierce, and not at all useful for viewing out on the highway. In a lighted parking lot, it’s fine. Great, even. Also, rain and snow. Just okay, but nothing unexpected or a design fault. It is what it is.Now, one other thing, and it’s not a design fault, it’s a part of what this device is… Think about it… You strap on this gadget that has a camera pointed straight forward onto your rear view mirror. It has a polished glass surface that is excellent for use as a rear view mirror all on it’s own. And what’s the first thing you do? You adjust the mirror, angling it down and towards you so you can center the reflection of the rear window in the mirror and see it by just glancing over, correct?And now that camera is pointed up and to the right, not straight ahead. It’s a very wide angle lens, and this is not really a problem, but I fixed it by making a small wedge out of foam and inserted it between the unit and the mirror it’s mounted on. Now the camera is pointed straight AND the reflection in the mirror is correct AND the rear-facing camera’s image generally matches the real reflection. This is important on dark and cloudy days.I know this all sounds like problems and issues, but they are really not. I’m a fussbudget when it comes to stuff like this. This is a really good unit and does it all. I like it a lot.

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.
