WOLFBOX FHD 1296P Dual Dash CAM

2021 New Version

We have upgraded the SONY lens with a higher resolution 1296P, used a bigger IPS touch screen to improve the display experience, equipped a 32GB TF Card. Clear quality will help to record all details for your car driving. Whether you need to guard passengers' safety, record certain driving moments, or keep an eye on the car, WOLFBOX is here to help.

Stream Media Rear View Mirror

G840S Stream Media Dash Cam will display the rear image automatically on the full screen when you start the car. The rear image is 1.5 times larger than the ordinary rearview mirror. Cleaner and brighter image can be seen behind the car synchronously with rare blind spot. Dual cameras gives you the better driving experience.

Enhanced Night Vision

Equipped with advanced Analogy High Definition (AHD technology ), the 1080P front and backup camera can automatically balance the light and dark area of the video to give you a better night vision experience.

WDR Technology

Suitable for situations like low light or back light, WDR is able to restore the true colors of objects to the greatest extent. WDR is able to show a fully balanced exposure, with the ability to compensate light and dark spots of the frame in one shot.

Reversing Aid System

When you shift to "r" gear, the rear view will automatically show on the screen with guide lines for easy and safe parking. You can enter the "Reversing line" option in the settings, then adjust the angle of the reversing image and the reversing line. Also when in reversing, you can adjust the viewing angle of the image. (This function activate after the red wire of the rear camera be connected to the positive pole of the reversing light.)

24H Parking Monitor

Turn on the parking mode, the cam will come to start recording once the camera detects shocks or attacks. The car camera supports 24 hours parking monitor and time lapse mode, please use WOLFBOX hardwire kit

G-Sensor & Loop Recording

The rear view mirror dash cam support manual trigger or automatic emergency recording with built-in G-Sensor. When the storage space is full, the front and rear dash cam will automatically overwrite the earliest videos segment with new files. With Loop Recording enabled, you never have to worry about purchasing additional cards when capacity is full.

Lane Departure Warning/LDWS

LDWS will secure your safety by sound alarm when your car is entering into another lane. Press the LDWS button on the Menu Settings to toggle it ON/OFF.

We suggest to turn on this function especially for long-time fatigue driving and novice drivers.

*Warm Tips:

  1. The front camera support 1296P / 1080P / 720P, and rear camera support 1080P / 720P, when the front and rear camera is recording simultaneously, it will be fixed on 1080P.
  2. Please check the functionality of dash cam with its all accessories before installation.
  3. Please don’t splice rear camera wire for extension, the monitor may lose the rear image. The length of original cable for rear camera is 20 feet, suitable for most types of cars. We also have 33 feet rear camera extension cables
  4. When using the parking monitoring function, please select the time-lapse recording mode. Otherwise, the driving recorder will quickly drain your car battery.
  5. Please format micro SD card termly in case of locked videos occupied much capacity, release them necessarily.
  6. Please use original accessories provided in the package, just in case of compatible issues after using others', especially use 2 or 3 in 1 cigar socket will lead to 100% insufficient current supply.
  7. If you use use micro SD card capacity > 32GB, Please change micro SD card〔Class10 ( 10MB / sec ) required〕 format to FAT 32 on PC ( a 32GB card is included in the package ).
  8. If your car does not have a reversing system, you need to connect the Red cable of the rear cam to the positive pole of your reversing lamp. If your car already has a reversing system, you just ignore the red cable on the rear cam.

    I bought it due all the weirdo drivers out there, i have had a few low speed accidents, which my Ins co took exception to, now if it stays and locks files like it claims, i would have a great record of the the incident. so ha ha. I will have to get the rear camera mounted if it cant take the prius back facing camera as is. The problem with the upside down screen has been fixed by a software setting, or turn the camera 180 while install. Turn it off, and you can use your existing rear view as its suppose to. I wish the box had a small battery if your car is hit hard and you lose car power. I am not sure if there is radar or proximity sensor in the back. When you are using the hud, it is not cluttered with info, and you can not show GPS or time. well thought out. Unlike others, I hope its life span is a long one. Powered by ciggy lighter cord.

    Camera quality is great. Very little headlight glare at night.

  3. otis boxill

    the quality is great and beautiful display back and front, i purchased it for my sfather who has an older truck. the issue is in my car its good no problem but my fathers truck every time he turns his truck off all the programmed settings reset. Like i said i have a 2014 car so to power the dash cam with the engine and power off is np. But his truck do not keep the power to the cam on. so if you have a car/truck whose cigarette litter lol doesn’t stay on while you’re not in the car problem with this cam.

  4. Tanner Bendele

    It works very good camera quality is actually excellent it records everything even when thereÕs brakes you lose may be a second footage because it can only record up to three minutes at a time but mine keeps beeping I turn the volume all the way down so I canÕt hear the beeping so itÕs not that big of a deal also I never could get the lane departure warning to work although my truck has a 6 inch lift on 35s itÕs pretty tall so I really canÕt blame it all in all would buy again and I have recommended to all my friends just remember if you want to get the footage off of it you must have an SD card reader for your phone or computer no Bluetooth

  5. Verified buyer

    Works well easy to set up. Only draw backs are that when the rear view camera is displayed you can’t zoom out and if you try to use the rear view camera image as a rear view mirror the screen still reflects what is behind you so it’s hard to differentiate. It works best just looking at the reflection.Also The ldws is really bad.

  6. The jephro aabides, man.

    Awesome, except night time headlights wash out a bug blob on screen. Prob an be fixed with firmware.

  7. R.T.

    This thing is actually really nice. I was surprised. I use it as a back up camera then leave it recording but turn it off and just use it as a regular mirror. It works great. Records dash cam and back up cam video at same time. I took one star off because the back up camera does need readjusted every time I close my hatch. There is no way to make it tighter in the bracket so it wont fall. But other than that it works great.

  8. Hello

     The camera doesn’t stay on 24 hours as a parking monitor. And the rear Camera doesn’t record. Both cameras are amazing against heat and dust and the rear back camera is water resistant I’ve washed my car multiple times. Amazing HD quality at night and day time. Rear camera parking assistant works just connect red cable to reverse light. I’ve had a front and camera that records 24 hours and it would of been 5 stars for me but doesn’t have that

  9. Seamus Singleton

    I would have given this 5 stars but you get sick looking at the moving camera while driving. This is because I wear reading glasses. Have to turn it off manually. Back up and record is great. Is great fir my younger daughter. Be sure to calibrate the backup so you can park correctly. But great idea just a lot of work. Plus the mirror is large and doesnÕt fit on some model cars.

    Originally purchased for my daughters car since her original dash cam broke, not sure if the shop that replaced her windshield had anything to do with it since it literally fell apart shortly after they worked on it?Since my daughter doesnÕt live with me and the item was shipped to my house I thought I would hook it up to my car since we had the same set up Drove around town a bit and really liked the setup. Will order another for me later. Loved the on screen prompts and menu, easy to navigate and set up. Images clear and has other user friendly parameters than my original camera. Very nice for the price. Longevity has yet to be determined.

    GPS baruch bis zu 5 Min. SD Slot wŠhre besser Unten oder an der Seite. Powerkabel hŠtte 1 Meter lŠnger sein kšnnen. Kollisons sensor sehr empfindlich muss auf niedrigste Einstellung ansonsten sind alle Videos gesperrt. ist schlecht ins Deutsche †bersetzt. Ansonsten gute Videos. Und sie tut was sie soll.

    Camera quality is good.

  17. David R Mcneese

    The controls are a little touchy but all in all a very good purchase…!!

  18. Joseph

    This thing rocks! 2017 promaster van…easy install..looks almost factory .The LDWS…kinda sucks..I’m hoping it might be user error??? The parking sensors are unpredictable..once again UE?The vid quality is awesome…the front camera enhances the view of the white line in heavy Tule fog…When you put the van in reverse, you vid. Pic changes to parking lines and a downward view, but when you put it in drive the mirror automatically switches to a longer distance rearview. I would definitely buy another.

    nice

  20. Jeffrey Chang

    The overall quality of this product is worth the value it is priced at. The only issues i have with this product is the sense of distance is abnormally different than reality. Additionally, the reverse parking function is somewhat lacking in functionality due to camera position and the sense of distance. And at night time driving, due to LED headlights of other cars it can be very bright to the camera. Thus, causing to not be able to see the license plates properly. Other than these issues, installing this product was easy and the quality of image that it produces is substantial.

  21. Amita Rani Sahoo

    Everything is good except the LDWS function which doesnÕt work at all. For me that was the highlighting feature for buying this product but it doesnÕt work anyway. Everything else is as per expectation.

    Good product, video is amazing . Daytime has a glare in bright sun , cant see clear view but in night works best. Works in hot climate of Saudi Arabia 41c + outside and in parking inside temp of car is 50c+ works well and cools down on AC start. A little line/scratch on screen! Overall a good equipment.

  28. Warlace

    Updated: Wolfbox was quick to reply and sent me updated drivers for the camera and now it is working as advertised. Only complaint now is the grainy black/white night vision of the rear camera. The front is amazing night vision but if you have a few cars behind you with their lights on its just one giant flare.So far it’s acceptable. Chief complaint is my mph reading is way off, shows me going half the speed I am actually going. And I do have my GPS set probably per the instructions, on the dash facing up through the window. When in the GPS settings on the menu, the bars are all over the place so not sure what is with that (in las vegas). Also when in rear camera view, I almost have a double view on the screen, one from the camera the other from the mirror itself. So when you looking at it initially it can throw you off. Will give it a week or so to see if I can figure out the bugs and can tolerate it. If not will return.Positive notes, the screen is huge and the touch interface easy to use, easy to install.

  31. Elaine

    Great camera. Fairly easy to install. I wish the rear camera recorded sound. But very satisfied overall

  32. Vincent S.

    The manual and website states that there is three display modes one of which is a screensaver function, I find that in the settings menu this is not correct.

  33. Sam bee

    Just installed this on my wife camry.Installation went really good. I wish they provide you with the plastic panel remover tool which you need,make it easier.As far as the camera itself you really need to get used to it. Something to mention that during day time there is glare in the mirror tried to put the brightness all the way still the same.The reverse guide lines are not really accurate. But at least you see the surrounding while in reverse.Also I wish it has internal battery for parking monitoring at least small capacity.The customer service is excellent thumbs up for that.I’ll put update as i use it more.

    I like the product a lot. It has nice features to it. I ended up getting a 64g sd card for it but the camera kept saying insert sd card so I put the one that came with it back in the camera and it worked. I had a lot of faith when installing the camera because I ran all of my wires before even testing the camera. The camera has good quality. I really really wish it had an app with it instead of it all being downloaded to the card. Hopefully some software updates to the camera could make this feature available. Not sure why itÕs not letting me add photos to the review though.

    Larger screen but also brighter and more clear than the smaller 10″ screens. Note that all these mirrors are very generic across all brands. I’ve tried the smaller 10″ mirrors and this 12″ IPS screen delivers better quality and a brighter screen to combat glare. Note that in a car that is very bright on the inside (no window tint to block incoming light) there is going to be glare. I wish they made true anti-glare screens but I haven’t come across any. Re-angling the mirror screen will help a bit but not eliminate glare. I am going to try an anti-glare laptop or tablet matte screen protector to see if that helps. To be continued.

    Everything looks good, but rear camera should have wider angle. The rear camera does not help much when I do parallel parking, I have to adjust picture on the screen/mirror to see how close the rear bumper to the obstacle.

  45. Tea lover

    I installed this to my Mini Countryman, because Countryman has a wide blind spot. Wide angle back up camera helped me to view the blind spot. The camera housing is made of full metal and looks to be very strong. However I found a gap between the housing and cable (I sealed this gap with silicone glue before installation). Overall I am satisfied by the high resolution of this product.
