Review: Great Picture Quality. The camera can see better than I can at night. - It really is a great dashcam and backup up camera. The picture quality is amazing and when it's pitch black at night, the camera has a great viewing ability. Truly amazing. I had a friend yesterday after installing it that it looks like watching a movie. I know installing it is intimidating and I had a friend help me but it's worth saving $250-$400. Here are steps and what to look out for: 1.) Remove passenger side A arm, that was on my side on my ford f-150 2007 for the fuse box. 2.) Remove fuse panel and use a circuit tester to look for 10 and 15 amp rated fuses that are insignificant like hazards, cigarette lighter (don't tie into airbags, ecm, etc in case something went wrong). The yellow wire with the fuse is your constant power and the red wired fuse is your 12v. Test with key on and key off either side of the 2 holes on the fuse. Make sure to ground the black wire to a bolt near the fuse box because it can't be a painted surface for a good connection. Dashcam fits over the rear view mirror with straps or adhesive tape. 3.) Remove tailight on passenger or driver side, depending on your vehicle. Run other end of camera under the frame (mine was the frame due to bring a truck) with zip ties up until above the running board. Remove weather stripping rubber next to seat and floor of front seat. Poke hole where wire junction is in the rubber to feed wiring up into the car/truck. (Easier than removing interior floor board). Run up A arm and tuck behind visor. *Don't run into hole by foot pdeals for 2 reasons. There is a hot exhaust manifold and there is barely enough length of wiring*. 4.) Poke firmly and I mean firmly to get a good contact with circuit tester (not a multimeter) on reverse light wire. Should be one of two. Put car in reverse, take key out with emergency brake on or have someone else reverse the car while testing it. Ground black wire near unpainted bolt by reverse light and clamp down on t-tap with existing reverse wire and new red wire for 12volts. 5.) Use T-taps and attach wire (believe its red) that's not black to the 12v wire you tested with a circuit tester. Attach black wire to ground. Use adhesive tape and in my case for best visibility, zip ties to back up camera. May want to use a fuse relay in case of a short in the future to avoid damaging wiring harness. Run up A arm and plug into rear view mirror dashcam. Great customer service that will call you back and give you technical support fir the installation. I ended buying the oem wolfbox g840h dashcam mount so it goes directly to my windshield instead of over the previous rear view mirror. Much better in terms of aesthetics so I recommend doing that. If you do that, thieves will never know its an aftermarket accessory they can steal. You're all set! I hope this helps as that's what I want instead of a video because it's intimidating for the first time.
Review: 4 years makes a world of difference! - Back in 2021 I picked up a Wolfbox G840S and had it hardwired in, it had a few quirks like occasionally not wanting to boot up in the cold, not talking to the GPS sensor and more... however it did the job I wanted it to do, it streamed the rear camera in real time and recorded front and back without issue. - I reached out to wolfbox and they generously sent me a second GPS sensor and when that failed, a second core camera unit. while the GPS issue never quite worked right, I wasn't too worried about it and was impressed with Wolfbox's willingness to work with me. Recently it would no longer take power, and attempting to troubleshoot it, I realized it was the base unit not keeping a steady connection to the power cable.... I reached out to wolfbox knowing it was past the 1 year warranty, but hoping maybe they could sell me a refurbished head unit (2021 model uses mini-USB). Really I just didn't want to start over from scratch and I really didn't want to have to rewire my car again. They responded back and while unable to get me a replacement for that model headunit, offered me 20% off refund on the purchase of a new one. I upgraded to the G840H (wifi\app enabled) which was on a 30% sale... and they still gave me 20% off that. I also picked up a mini to USB-C adapter to reuse my existing power. Changed out the main unit only, using the adapter and it came right up. My only complaint is it no longer seems to "detect" when the car is off, going into parking mode, but my answer to that is to just unplug the power from the adapter. Yeah I don't get parking mode, Which I used a few times when I was curious... but honestly I've not really needed it and I know it's mostly likely due to me using the older wiring harness + adapter vs getting a new one and either having it put in or doing an install myself. After getting it up and going, it worked with the GPS sensor (the first one) that supposedly wasn't in an optimal position (center top of windshield, vs their prefered of center bottom) - picked up time, used the card already installed (didn't put in a bigger one since this has wifi to pull quicker) picture was not only everything I expected of my old one, but sharper, cleaner and it even "erased" the lines that I usually saw out the back camera from the rear defroster (camera is mounted inside the rear window near top center) GPS is working so I get speed and direction + automatic time updates... App worked great with little issue, able to connect to it anytime i'm in range. This makes our 3rd wolfbox streaming mirror with the other one being in my wife's jeep (and the first one being the one I just replaced) - now if only they made a motorcycle dash cam, we'd have one on every vehicle (used rexing for that one and it's just not as good.)

### ⭐⭐⭐⭐ Does what it's supposed to do.
*by A***R on December 19, 2024*

Replaces the OEM mirror on my pickup, which has a tinted rear window, plus a tinted front window in the Leer cap, plus a rear tinted window at the tailgate window, thus visibility has been dismal since I added the cap. This fixed that. I actually screwed down the rear camera to the top of the cap above the tailgate window, drilled a hole thru the cap, having purchased a 50ft camera cable routed that thru the bed and underneath the truck frame to the engine compartment and into the foot well on the drivers side, then a piece of cake to route the wire to the mirror. This mirror/camera works very well, gives me great visibility out the rear, has an image that shows a wide image so easy to see pedestrians or vehicles crossing behind me. It also provides front and rear dash cam functionality , which was really somewhat less important to me, but is good to have on any vehicle. Easy install and setup, the app works just fine on wifi, I can get videos off the device. Only issue is the device is occasionally intermittent starting up when powered off a cigarette lighter outlet, a press of the on/off switch is sometimes needed. WolfBox was contacted, they are sending a free hardware install kit to wire direct to the fuse box, it's supposably more reliable. I am overall impressed with the image quality and functionality, it solved my rear view problem. As well, I will be purchasing a 2nd rear camera to install on the rear of my small camper to give me a rear view and backup camera, plus additional ire to run to the camper bed. EDIT: I added the hardwire power kit, which had all the parts necessary to get the mirror power into the truck fuse box, pretty much effortlessly, I also added the vehicle mirror mount. I had to e-mail Wolfbox for info on what model fit my Frontier, they got right back to me and I purchased, received, with install taking about 15 minutes. I am very happy with their products, will add a 2nd camera to my small trailer soon.
