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.

The Wolfbox was easy to install. I’m glad I elected to DIY instead of paying someone. I watched a few Youtube videos and was able to install all features, ie mirror, gps and rear view camera. The most time consuming part was tucking the long cords into the interior trim but I took my time and got it done with no wires showing. I installed it into my 2005 MB SL500 with ease. I had to install the rear view camera on the interior rear window as there were limited options based on the design of my trunk. Video is of exceptional quality on the front cam and good quality on the rear cam because it is looking through glass. I found there is extreme glare in the mirror but using the settings it can be adjusted which helps. You can also adjust the rear cameras for those of you saying it displays video upside down; it’s in settings, you can flip the angle. I’m still trying to figure out how the wifi benefits me. I would have preferred blue tooth. I also downloaded the app. I have been using the mirror for about a week so still figuring out a few things but now regrets. It was money well spent. I absolutely love the screen size and park assist.

I installed this on a 2021 Cherokee. The wire to the camera snugged in at the top of the windshield by the headliner, and mostly fit on the right side of the windshield. Under the dash with black gorilla tape and to the ignition-on 12V outlet and I was good to go. It is really hard to tell from outside the vehicle that I have this in place. I didn't consider the GPS feature something I needed long term but I did try it out. and it seemed accurate in terms of speed and direction. I did not wire up the rear camera, as that would be much more involved and I didn't particularly see the need for it. Even in a disputed accident the front camera will show you were doing nothing wrong when you get rear-ended or hit from the side. After the screen saver for the front camera kicks in and darkens it, the mirror is dark gray but reflects well enough to be useful day or night. Even during the day, with a tinted rear window and sunglasses, I can see behind me. Since getting this 20 days ago I've driven 3200 miles with it. I will say a number of good things about this camera. The resolution during daylight is outstanding and sharp. At night it is still quite good, but like most cameras, there is much glare from headlights. Getting a license number under many circumstances would be tough in many cases. The night image goes contrasty monochrome most of the time at night, but if your headlights illuminate a sign, or a double yellow line, you get some color there. It really records the roadway well, even in blowing snow and fog. The manufacturer makes some effort to personally answer questions if you do, as invited, email them. The manual is not in very good English, and it doesn't answer some basic questions about how to use it. I emailed them and some effort was made to answer my questions. And that alone is a rare bit of effort from the mfg. I asked, however, about issues (I'll get to those) with their player and got a boilerplate non-response, prefaced with a weird "bless you" introduction I'm more accustomed to from Liberian scammers. My most recent questions were essentially ignored; I asked how to use their player (see below) and they recommended I use their player. Thanks. Not helpful. Their player is awkward and glitchy. And they give you no instructions on how to use it. If you click on the player's "about" tab to try to learn how it works, you get information on the manufacturer and all its products, not the player. It locked up my windows 10 machine several times. I couldn't find my still photos or a couple events I recorded. The videos are in "TS" format, something my laptop cannot play as currently configured. So I looked around on the internet and downloaded a free "TS" format video viewer called "VLC Media Player," and it works great. Time stamped 3 minute videos are there, still photos are there, and things I "locked" are saved as "events." This third party free program fixed my biggest frustration with the product. I still have a question about the product I don't know the answer to. If an "event" happens, like an accident in front of me, and within 10 seconds or so I push the "lock" button, does it back up some? So I don't lose something happening in the last 3 seconds of the 3 minute section containing the accident but just before the one running when I hit the lock button? I installed a 128 GB card so nothing is going to be quickly overwritten anyway. So overall, for the price, I am very pleased with it. Daytime video and stills are really good. A still of a three car snowy pile-up is attached to this review. The GPS gizmo worked fine, but I'm not sure I always want my speed recorded and the vehicle already has a compass and two speedometers built in. So I won't be using that. Due to the oddness of the instructions, which don't cover some basic things, you do have to do some figuring out on your own. It wasn't hard though. If this one has a decent lifespan I'd gladly get another down the road. I'll probably get another for a second car too.
