VIOFO A129 Pro Duo 4K Dual Dash Cam 3840 x 2160P Ultra HD 4K Front and 1080P Rear Car WiFi Dash Camera 8MP Sensor GPS, Buffered Parking Mode, G-Sensor, Motion Detection, WDR, Loop Recording

I just bought an A129 Pro Duo to replace a Mini0906 (that thing was NOT one of the best cams like dashcamtalk claimed, but was a complete turd). === Let's get the negatives out of the way: On the A129 Pro Duo, the wifi feature is not broadcasting. I have tried 2.4GHz, 5GHz auto, and 5GHz forced to channel 40, and 5GHz forced to channel 36, and forced to 161; the SSID is never broadcast. As the MAC is not listed on the device (SHAME ON YOU, VIOFO!), I checked for new APs without an SSID and toggled wifi on and off, and no new MACs showed up, so it appears wifi is totally nonfunctional. It is otherwise a fantastic unit and I will be updating the review after I test night recording. I'm docking four stars as one of the reasons I bought this unit was wifi connectivity, and yet, I will be forced to pull the microsd card and use dashcamviewer to review footage. WTF, VIOFO? Fix the firmware please. Docking four stars for this. Also, Mini USB connectors? Why not USB-C? WTF? If you had used USB-C I could have prewired my car before the camera arrived. No volume setting for that infernal beep? Only On/OFF? I want the beep, I just don't want it to be eardrum-piercingly and nerve-gratingly loud. Do us a solid and give us a volume control for the beep, please, even if it's just "LOUD - MEDIUM - SOFT - OFF" And, why not a full kit which includes the hardwire kit, bluetooth remote and polarizing filters for both the front and rear cameras? OK, so with all the negatives that garnered a 1-star rating (only because I could not rate it zero) out of the way: === Positives 1. IT HAS A SCREEN! I skipped the Thinkware U1000 because even though it's objectively a better product, I wanted an integrated screen in case WiFi fails 2. DAY, FRONT Video quality is GREAT - at least in daylight (I will update this review over time). 3. It is easy to install 4. I like that there is a prewiring kit and a customizable parking mode (again, I will update this over time) 5. I like the visual recording, wifi, and mic LED indicators so I can check without having to wake up the screen 6. THANK YOU for implementing a screen timeout/"screen saver" feature. With most dashcams with screens, I need to manually turn the screen on and off. It's nice being able to tap a button and check status and let it time out and turn off on its own 7. I like that it's low profile and will not interfere with the visor as much as other models do. 8. I like the faint LED in the GPS mount; with the camera pulled off the mount, I can see that the GPS mount is receiving power 9. I like that WiFi can theoretically be toggled on/off with the overlay button (I say theoretically because WiFI actually doesn't work at all) 10. === Suggested improvements: * Switch over to all USB-C connectors * Support 1TB+ MicroSD cards * Allow your app to read MicroSD cards (since wifi doesn't work at all) * Implement a more active cooling scheme (phase changing heat pipe + maybe a fan) * Cloud recording/storage/vehicle tracker/locator connectivity: Cloud connectivity? (I'd subscribe for $5 to $10/month if you would archive 30+ days of coverage and allow easy merging/exporting from the cloud - this would be a nice recurring revenue stream for you) * Car locator feature (easy with GPS + cloud connectivity), with live view * Android Auto/Carplay integration to use rear channel as rearview mirror in infotainment for those of us who drive vehicles with useless back windows (sportscars, trucks, etc.) * a full kit which includes the hardwire kit, bluetooth remote and polarizing filters for both the front and rear cameras? * 3 channel support * higher quality sensors both front and rear <---<< * flip screen or android auto plugin to display either channel, use rear channel as supplemental rearview mirror view === Update day 2: I haven't recorded any footage for a review/sample video yet; I have been playing with parking mode settings and H.265 vs. H.264 and when I used H.265 and let parking mode run overnight and retrieved it in the morning, the camera was so hot it felt scalding - it hadn't been in the sun yet and the car interior was still cool. I did not have my IR thermometer handy so I did not actually measure it but I'd guess it was 70c at the very least. I was nervous letting it run in my Stinger so I disabled H.265 and reduced the video bitrate from maximum to high. Resolution maximum, WDR enabled, bitrate Maximum, EV = 0, rural/light suburban roads: Reviewing day footage on 4K screen w/Dashcam Viewer, I can easily read license plates of cars I am following. It is very difficult to find any frames where license tags of oncoming cars are readable. However, nighttime capture of registration tags are not readable. There is much blooming which of course obscures much of the scene. Rear channel, 1080p: Reviewing night footage, WDR enabled, bitrate Maximum, EV = 0, rural/light suburban roads: License tags of oncoming and following cars unreadable. Rear camera underexposed, difficult to make out detail on rural roads, cannot read following vehicles' plates (expected). Basically, meets expectations, provides some protection. == Exchange VIOFO want me to send the camera in for exchange. If it comes to that I'll do an Amazon exchange, returning the replacement box with the old camera since I had already installed the cables and tossed the package in recycling. I was hoping they'd come back with "Oh the firmware is buggy and here's an update" :-( On the bright side they respond fairly quickly. === Corrections to previous complaint: Time DOES appear to update automagically via GPS. === Update: === I received a replacement - I submitted a support ticket and they made the exhange super easy, with advance shipment of the dashcam. I am pleased to report that the wifi features work on the replacement camera. I am happy with the unit so far. The high temperature does concern me a bit though. === Update 15 months later: === Unit is under the extended warranty (I had to register it because the original came DOA). I was previously very happy with it but now the camera is freezing when powered through the integrated USB port. When powered through the GPS module/mount it functions fine - NO freezing, but the unit runs hotter and drains the battery quickly when powered through the GPS mount (this is a common problem discussed on messageboards, mentioned in a couple reviews here, etc.). Well, they tried to blame the USB cord (uh, no, I am using the hardwire kit), or the SD card (I already indicated I write/read tested the SD card using both Windows and Linux, so the SD card is not the problem), or parking mode (No, I will NOT turn off parking mode, as that is THE feature which prompted me to select this product). As such, all the way down to 1 star because their customer service has declined and they're obnoxiously patronizing with their canned responses. === Another update, a few days later === I just learned they are off for Chinese new year. With that in mind, I can only conclude they took the time to try to lend some support during the holiday so I am restoring my original rating of the product, and I humbly apologize to Viofo for my jumping to conclusions.

Update: I increased my previous review to 5-stars. Viofo reached out to me and had me update my firmware. So far, it's worked like a charm! Great support team! We had several conversation back-and-forth to problem solve the issue. I'm still using the dashcams and they've captured some amazing things! I've had this dash camera for a few months now and can honestly say I wish I would've purchased a different one. I haven't reached out to customer service yet. I wanted to provide my first impressions. This is not my first dash cam. My previous one was an expensive one that did the job. Quality was good. The best thing I like about my previous one was the reliability. I had it hard wired to my truck so when I started it, it came on, recorded my trip, and when I turned off my truck, it would stop recording. Super simple. I could pull the SD card out, pop it in my computer, and everything was there to review. Exactly what I want in a dash camera. This brings me to my VIOFO A129. I opted for this model because it has 2-channels, parking monitoring, and 4k. The features work great when the camera works. I find that it records when it wants to. I've use the app over WiFi to check my records and 75% of the time it doesn't record my driving. During a 10 minute drive, it'll restart at least once which isn't comforting. Sometimes it'll constantly restart then stop. Sometimes it'll start beeping ever 2 minutes while I'm driving. I've swapped SD cards thinking that might be the issue but after a day, it would repeat the restarting and beeping. So now, I constantly check that it's recording while driving for piece of mind which is not what I should be worried about for something that's supposed to provide piece of mind. In summary, I would look for something that works and does it well. Basically, set it and forget it until you need it.

Let me preface by saying, I would of uploaded a video of the footage, but there are tons of other great videos out there demonstrating the product, and I do not want to give out my coordinates. So you are just going to have to take my word for it. If you are a tech-savvy person, read on. If not, whatever, Im not getting paid. I personally have the highest speed recommended MicroSD card inserted into the dashcam, which is a Samsung microSDXC Evo Plus 256GB, UHS-1. The speeds I get writing to my SSD are around 33-40MB/s. Which.. is decent. I would recommend this card because its the best you could get thats recommended in the manual. Although samsung doesn't have a warranty on this MicroSD, due to dashcams having an intense write to the card. With that aside, I recommend writing the footage from the MicroSD to an SSD, then archiving it to a spinny disk of your choosing. I use my laptop for portability. Now.. This is a true 4k dashcam. I have seen dashcams that claim that they are 4k, but do not have a true resolution of 3840 by 2160p. The front dashcam is 4k, and has a very high bit-rate, which makes this dashcam topple every other dashcam in the market. The rear dashcam is unfortunately 1920 by 1080p, and does not have the best bitrate in my opinion. This is probably to save space on the card, but for $250, you have to cut corners somewhere. I will section off this review by going over the front and rear dashcams, but let me start off by saying I have 5% tint all around, and 70% tint in the front windshield. Also, Ive driven for about 90 minutes of footage now and I have used up 40GB worth of footage. I run my dashcam on the highest resolution on both cameras, and the highest bitrate on both cameras, sectioned off into 1 minute clips, both front in rear. The dashcam sections these off into numbers, for example: "20200818_101037R". These break down into the following: 2020 - year, 08 - month. 18 - day, _ - separates the day with the exact time, 10- military hours, 10 - 10 mins, 37 - 37 seconds into the minute, R/F - Rear camera and Front camera respectively. The dashcam records these files in MP4 format, so every computer has the capability of reviewing the footage, IIRC. Its easy to see which Front footage goes with the Rear, because they share the exact same time stamp, so there is zero confusion there. Audio records from the front facing dashcam, and shares the same audio when looking at the rear footage. Front: Ive previewed the footage on my 4k laptop and cross checked on my Samsung 4k monitor, and the resolution is very crisp, and quite frankly amazing. Every frame you pause the video on, you are able to make out EVERY SINGLE LEAVE on every single tree. The high bitrate is outstanding. The resolution is outstanding. With cars parked on either side of the vehicle, you are able to make out the license plates, the camera lens makes no compromises from extreme angles. The only con I have about the front dashcam is when the sun is shining directly onto the license plate from your point of view. As you know.. license plates are extremely reflective, and when the angle is right, you are unable to make out the license plate due to the shine from the sun. Night driving is spectacular, with 70% tint, I am still able to make out license plates from 3-4 car lengths away. Note that both dash cams auto adjust their exposure levels. Rear: **PSA: Please make sure you mount the rear dashcam ABOVE your heating element, so the sticky pad does not ruin your rear defroster, if and when you decide to remove it, and make sure the camera is looking THROUGH the heating element. This is to prevent foggy footage if your windows fog up during the night time.** Looking at the footage, day driving looks good, not great. You can barely read out the license plates when looking through the rear dashcam, but if a vehicle passes you, the front dashcam will pick up their license plate. In my opinion, the rear dashcam is a "I'd rather have it and not need it, then need it and not have it" type of situation. Its useful by determining the make/model/color and prior damage of the vehicle, but picking out plate numbers from the rear is a challenge. You might be able to make out one or two characters of the vehicle's license plate, but good luck. Like I have said before, I have 5% tint on my back windshield, however, at times before 7PM, the rear dashcam is very effective. Looking through the camera at night, the only thing you are going to be seeing is your 3rd brake light shine, which is a good indicator that you are pressing on the brakes in the event of an accident. The other party will not be able to say that you weren't. Thats IF there is no car behind you. If there is a car behind you, thankfully the dashcam adjusts the exposure, and you are able to see the car's front hood and two lights. You're really banking on being under a street lamp to see anything more than that, if your car has 5% tint. I wouldn't worry about it too much, because the chances of a car being behind you at night with no lights on is very slim.. Interface: There is dedicated buttons on the front of the camera, so no need to touch the rear camera after installation. Dedicated Mute button, dedicated wifi, dedicated "lock footage" button are all very welcome. Yes I said WiFi, yes, the app is trash and crashes from time to time. In the box, it includes a MicroSD to USB, which is welcome if you do not have a MicroSD card reader, so there is no reason to look at the app to check the WiFi footage (supports 2.4ghz and 5ghz connections). Some people have the hard wired kit and say they can look through the dashcam when the car is off, but I can't confirm/deny that because I do not have the hardwire kit. I will take a battery pack with me and use it whenever I park in the city if I want to be extra cautious. Audio: Worth a mention, the microphone used in this product is pretty good. It picks up the higher notes of music, so if you have a bass heavy sound system, you are still able to hear, and wont get drowned out by the bass. TLDR - I recommend this product. I gave this dashcam 4 stars because of the low bitrate for the rear camera, making it near impossible to read out license plates. Other than that, its a solid product.

Crisp images and videos. Having a dash cam is in must nowadays with all the types of reckless drivers. The sensor in this one is actually high-quality, unlike the rest of the cheap dash cams you’ll come across. This one lives up to its expectations and after buying so many different cheaper dash cams, I settled on this one after I found it to be reliable. Not to mention the large amount of storage SD card will accept the Wi-Fi feature is also useful for viewing footage on my phone. I also keep an SD card adapter that way I can take out the SD card and check the footage on my phone or laptop if I need to hardwiring, it is probably not a bad idea so that you can capture parking incidents as well while the car is off.

I first bought this dash cam in early August 2021. The unit I received would not transmit a Wi-Fi SSID, so I was unable to connect it to my iPhone. I contacted VIOFO support and they had me send the camera back to Amazon, which I did. Amazon then sent me a replacement camera 2 weeks later. The Wi-Fi on the replacement camera worked great. Fast-forward to July 2022, when one after another, things started going wrong. First, the Wi-Fi died on THIS unit as well (it too stopped transmitting the SSID). Next, the display stopped showing the live view (it would only show a black screen with the word "VIOFO" in the center, yet the camera was still recording). Lastly, it stopped recording the rear camera view altogether. Resetting the camera, updating the firmware and checking all the connections made no difference. I would love to give this camera more than a 1-star review, because when it worked, it worked great. The video quality of the front and rear cameras were very clear and sharp. The Parking Mode worked great as well (I also installed Viofo's hardwire kit). But for things to start going wrong after less than one year? I'm extremely disappointed. I've seen other reviews here saying their camera's Wi-Fi stopped working as well, among other things. I'm very glad I purchased a 3-year warranty with Asurion (since the original 1-year warranty had just expired) and I just filed a claim with them to get a replacement (which will be my SECOND replacement). But unless they've started making these dash cams more reliable over the past year, I cannot recommend this dash cam. UPDATE 09/02/2022 I filed a claim with Asurion for this camera on 08/30/2022. They asked me to send it back to them. They received it yesterday morning. And just THIS morning, they contacted me saying it can't be repaired and that they're reimbursing me for the purchase price of the camera. Looks like I'm now in the market for a new Dashcam, from a DIFFERENT manufacturer.

I had previously purchased a Rexing V1P Pro camera, which I liked, but the GPS encoding on the video files was in a proprietary format, so I returned it and bought this. Whereas the other camera is bulky, but lightweight, this camera is small, dense, and surprisingly heavy. One feels like a toy when compared to the other. I chose to use the default power connector, as parking mode is not important to me. The kit comes with a lot of extra mounting tape, so if you mess up your placement, or move it, you are all set. Be careful to leave room for the power cord when mounting the GPS block. I almost mounted it too close to where the rear-view mirror mounts on the windshield, and had slight difficulty plugging it in. The wiring with this camera is thick (heavy duty), and holds it’s shape well, which makes it real easy to install. This is only the 2nd time I’ve ever installed front/rear dash cams and it literally took me less than 15 minutes. Because the wires are so thick, they hold their position well, and hiding the wires from the front dash cam into the header is real easy. The kit also includes a tool to help install the wiring, which is real nice if you haven’t done it before. The memory card slot is on the left side, so removal is convenient. Just be sure to use two hands when ejecting the media. The camera will slide off the GPS mount if you push too hard. This is the one thing I think I would have designed differently. If the mount clipped on and slid to the right (instead of left), you could remove the memory card easier. This camera shuts off the screen when you’re driving, which I wasn’t used to at first. After running it around for a little while, I actually prefer this to other dash cams, as it is less distracting while driving. The iOS software is very good. I found only one bug, whereas if you put the camera resolution into 1080 x 1080 mode, the app will crash immediately when you try to connect to it. The app functions as expected under all other circumstances (so far). The 5GHz wifi is FANTASTIC. Download times for clips are blazing fast as compared to the other camera I had used. Note that 4K files are huge (1.6GB for 5min), so it’s going to be more efficient to remove the memory card and plug it into the computer. Speaking of which, VOIFO even provides a USB adapter for the memory card. Video clip options are great with this camera, offering 1,3,5 and 10 minute clips. Personally, I like to divide the clips into 5 minute segments so this camera does exactly what I need. The only thing that I wonder long-term, is how well the card slot will hold up from constantly removing the memory chip to retrieve the footage. For this reason, I purchased a warranty for the camera. The 4K video quality is absolutely amazing, and the 130/140 field of view front/rear is perfect. Unlike other cameras, there is no fisheye effect due to the wide angle. The mic on the camera also exceeded my expectations. The only annoying/missing feature on the camera is the lack of a daylight savings time setting. You must switch the timezone offset to match your timezone when daylight savings comes and goes. This is a software setting that could easily be addressed in a future firmware update. Not a dealbreaker for me. 4K video playback is choppy in dashcamviewer on macOS due to Quicktime. Too bad, as that’s the whole reason I bought this camera. I’m hoping that newer builds will read the H.265 codec. RE: H.265 codec, there is an undocumented feature where you can change the encoding from H.264 to H.265 by holding the mic button for 4 seconds. H.265 encoded videos will play smoothly in Quicktime on macOS, whereas the H.264 videos will not. Both formats play perfectly in VLC, so if you don’t care about following your footage around the map while you play it, even better! The software has options for displaying speed and GPS coordinates on the footage if you want, and you can hide the camera model from the footage if you prefer not to show it. I have not seen that feature on other cameras. Additionally, you can add a custom label to your dashcam footage which might be useful. If you’re looking at other cameras, and you’re wondering if the cost differential for this one is worth it, I would say go for it! The worst thing for me is the poor 4K playback support in the software I wanted to use, but I’m confident the developer will solve that as more 4K cameras hit the market. Virtually everything else about this camera either meets or exceeds my expectations.

The basic functionality of this dash cam is great. If you're comfortable doing car stereo installations, or similar projects, installation of this camera system is not too difficult. I did install the hardwire kit so the camera will continue to record when the car isn't running. I highly recommend you do the same if your car spends anytime parked outdoors in suburban or urban areas (as most cars do). The camera records at a high quality (4K in front, HD in back) and can log your speed and location. 4K resolution increases the likelihood that you can get a license plate number from your footage. GPS is crucial if you ever need to present video evidence in court as a judge may not accept the video if you cannot prove the location of where it was recorded. As long as you use the highest memory card possible (256gb) you can record many hours of video before the camera begins to write over the oldest footage. The app (iOS) also works well to review footage and change settings on the camera. The camera also records audio from inside the car. This could be invaluable if you ever have a not so positive encounter with law enforcement at a traffic stop. You know that you have an audio recording and you don't necessarily have to risk agitating the officer by shoving a cell phone camera in his face. The problems I have with the camera deal with the "specialty" features. First off the is the g-force sensor. This is is suppose to detect sudden movement while driving such as a collision and automatically lock the video beginning fifteen seconds before the movement and thirty seconds afterward so that it will not be overwritten. Even on the lowest sensitivity, the camera almost constantly is registering sudden movement while driving. Even after a short trip, I have a very large number of "locked" videos due to the g-force sensor triggering. These videos have to be manually deleted. Otherwise they will just sit there, taking up space on the memory card. Parking mode has a similar issue. The most advertised feature in parking mode is the event recording where the camera will automatically record an event if it detects motion. Once again, even on the lowest sensitivity it is recording events almost constantly (birds, wind, leaves, rain, shadows... anything), and all of these events end up locked. So you also have to manually delete these files along with the files triggered by the g-force sensor or risk filling up your memory card with meaningless files that will not auto-delete. The g-force sensor is also supposed to work in parking mode so it will trigger an event if somebody were to hit your car in a parking lot or something along those lines. However, I have no idea how well it works because the motion sensing is so oversensitive I have no way of knowing if it's the motion or the g-force sensor triggering an event. Unless you park in a garage, this mode is essentially useless. Needless to say, I have disabled the g-force sensor while driving and I use time lapse mode while parked (g-force sensor does not work at all in time lapse mode). Overall, I would recommend this camera to anyone that doesn't care about the special features not really working. The price is about the best you will find for a 4K camera that records front and back (1080 in the back). I am undecided if I would purchase again. I am disappointed with the features that don't work well, and would probably explore other brands/models to see if there's anything out there that can actually do everything it claims it can do. But for now, I am glad to have a camera set up that is recording high quality footage while driving.

This A129 is my third of the 129 series and my 6th of the line. The first was a B40 followed by an A118 then A118c. The A129 was the first of the capacitor models that worked well but was plagued by times when it would randomly not record. This new A129 Pro is a very good camera. The resolution is fantastic and has no problems catching street names and license tags even in moderately low light. The rear camera is still the old 1080p at 30fps but it can easily catch the hand gesture or random deep nose foray of the person behind. The number one problem is still the occasional recording issue. This A129Pro will sometimes randomly not record and require the media card to be formatted. Once it is formatted it will record without further issue for a wee or three. There was an issue with a card I used in my standard A129 that refused to record in the A129 Pro for more than 15 seconds. When the recording stopped there was no flashing LED or audible sound. Formatting in the camera did not fix it but the card worked fine in the standard A129 afterwards. In my opinion a dash cameras most important feature is that is is always recording. The one time I need it after being pushed from behind in the fast lane by a trailered work truck then driven off the highway and had a gun pulled on me, the camera was not working. Thankfully to, a stopped freeway of onlookers and several good Samaritans, I got away unhurt but could not file a hit-and-run or road-rage complaint. Close Viofo but not quite there. Keep trying, you'll get it soon. EDIT: I have changed from a 256GB video card to a 128GB card and the camera has not missed a recording since. as the higher data rates become more common it will start to be important to be functional with the larger capacity cards. I am upgrading my rating to 5 stars. This is an amazing camera when hardwired and using a memory card.

The front cam is excellent and does the job well. For the rear cam the exposure needs to be adjusted if you have a window tint

I have been using my GoPro Hero 8 as my dashcam for many years, however, it gets too hot and turn itself off many times during the summer. Then I decided to get a solid and reasonable price dashcam instead. I have reviewed several dashcams online, and finally decided to get VIOFO 4k Duo from Amazon. First, it's under my budget of $300 (honestly I don't think $800 BV is worth it) Secondly, it's 4K and the quality is one of the best after few reviews over the years. Third the App is easy to use and there are lots of tutorial video online about this one, it's easy to learn and easy to operate. However, I quoted a price for dashcam installation in my Ford Ranger, the bodyshop I used to visit, asks for $300 for the whole process. After viewing several DIY videos on YouTube, I decided to do it myself. The good thing about Ford Ranger, it has a USB slot right behind the rear mirror, I could connect the dashcam using a short power cable, which is the same type of GoPro Hero 4. It only took about one-hour and I saved $300 easily! I tested it several times, the video quality is really good, especially under 4K, I could save the video directly from my iPhone and edit the video on the phone. I would say it's a really good deal if you are thinking about the protect your valuable car and win the claim after the accident. I would recommend it to others. Please note, don't hide your cable near the airbags as I shown in one of the pictures. I accident did it first and one mechanic told me that it would create more damage to the driver when the airbag pops out. So always hide the cable through the bottom section of the door frame.

This front and rear camera along with the gps module are easy to install. The cables are of good quality and the power adapter fits in the cigarette lighter. The quality of video both front and rear are very good.

شفت لها مقاطع كثير يجربون يحطونها في ظروف قاسيه وشغاله وتتحمل، دقتها بيرفكت ويستحسن شراء فلتر العدسه اللي يمنع الانعكاس لصورة افضل (خصوصاً في الليل) غير عن كذا ما شاء الله وضوحها عسل وتلقط اللوحات بالراحه.

If you’re reading this, this is the sign to get this. I've had these installed in my car for over 2 years. Got into a hit and run when my car was parked in a parking lot. Someone hit my car while backing up and hit my car, causing a small black scratch. Luckily I had parking mode and filed to my insurance and was found not at fault. My insurance paid for everything in 2 weeks. Shop bill was $2.5k CAD and about $500+ in Rental. I paid 0 thanks to this dash cam. I would've been driving around with a scratch on my car and the other person wouldn't of face any repercussions but they're now screwed since their insurance is categorizing them as high risk driver for not staying or reporting. I was thinking to myself, one of these days the dash cam will pay for itself. It sure has. This is your sign to get one. And yes, get yourself a viofo or this model. I've done countless research and this model is the standard one you should get. It’s 4k at the front and 1080p at the back but slow wifi chip. Get the newest model with better wifi chip so you can transfer files 10x faster, otherwise be prepared to sit in your car for a hot minute while transferring clips from your dash cam to your phone via app on wifi. 0 regrets.
