Great Camera, Just Use the Right Memory Card
Review Image by John
I installed the VIOFO A229 Pro in a 2008 Hyundai Santa Fe and hardwired it with the HK4 kit. Install was pretty straightforward and once everything was set up it worked exactly like I wanted. It switches into parking mode when the vehicle is shut off and goes back to normal recording when it’s started. The 4K front camera was the main reason I went with the Pro instead of the A229 Plus. Picture quality is excellent so far. It’s sharp, HDR handles bright skies and darker areas well, and the view is wide without looking overly distorted. I only have the front camera installed right now but plan to add the 2K rear camera later. GPS works well and can put speed, coordinates, date and time on the footage. The 5GHz Wi-Fi connection to the app has also been good. Once connected, it’s easy to change settings, look through recordings and download clips. Mounting is all 3M adhesive. There is no suction cup included. I actually prefer the adhesive mount for something that’s going to stay installed because it feels solid and doesn’t move around or have to fight the heat. One thing I did run into was the memory card. I originally used a 256GB SanDisk High Endurance card and formatted it in the camera. Within the first day I started getting a “chip slow” warning along with repeated beeping. I ended up replacing it with VIOFO’s 256GB Industrial Grade card. I’d recommend sticking with one of VIOFO’s approved cards from the start, especially with how much data the camera is writing in 4K. Overall I’m very happy with it so far. The video quality is excellent, parking mode works properly with the HK4 kit, GPS and Wi-Fi are useful, and I like being able to add the rear camera later without replacing the whole setup. My only real complaint is that you need to pay attention to memory card compatibility. ... show more

A Very Good Dash Cam, Excellent Customer Support
I started looking for a good dash camera last year, after my car got a rear-end hit. I tried a couple of different cams before getting a 2-channel VIOFO A229 Pro, and I did a lot of testing under various driving and lighting conditions to evaluate the camera and optimize its performance. Though not perfect, it is a very good robust camera for everyday use and documenting a potential accident. Here are some highlights that might be helpful: Both front and rear cameras incorporate advanced Sony STARTVIS sensors (4K IMX678 and 2K IMX675, respectively) to ensure high-quality video and improved low-light performance. The design is well-thought and polished. The front camera windshield mount incorporates a sensitive GPS module that can provide coordinate/time/speed stamp on the video footage. They use convenient electrostatic plastic pads to easily attach/remove cameras to/from the windshield. A direction of the field of view can be manually adjusted for both front and rear cameras. Its flawless operation is controlled by a good software with a lot of settings to optimize its performance with regard to operational conditions. It has a nice display and a set of buttons for manual control. The camera operation can also be controlled and monitored by a phone application via fast 5G Wi-Fi. The camera kit is nicely packed and includes all accessories and cables to setup and use the camera in your car. It includes a CPL filter to minimize potential glare and dashboard reflections, but does not contain a memory card that should be purchased separately. In my experience, various (not even the fastest) cards from SanDisk and Samsung worked well. The video files are pretty big, so at least 128GB is recommended for everyday use. For example, 3 min footage (with panoramic 21:9 aspect ratio) from the 4K front and 2K rear cams takes 1.25GB and 0.516GB, respectively, so the 128GB card can keep record of about 4 hours. Setting the 21:9 aspect ratio (3840x1600 and 2560x1080 pixels for front and rear cams, respectively) reduces the recorded vertical width of view (and the file size!) to focus on the driving conditions instead of capturing images of the sky or the hood of your car. The wide-angle lenses of the front and rear cameras provide good fields of view for general monitoring of driving conditions, but complicate capturing plate numbers from a distance. In my practice, the A229 Pro front camera can provide reliable reading of plate numbers of a car ahead from a distance of up to 3 car bodies at daytime. To increase the distance, one can use the VIOFO 2K accessory tele-camera RTC300 that connects to the front camera instead of the A229 rear camera. The tele-camera operates in conjunction with the front camera and greatly (up to 4 times!) improves the distance of license plate reading, while the front camera still provides broad field of view. I use such setup for about a year and, in my experience, it works very well. The problem is that the front camera does not have an extra port to connect the 2K rear camera included in the A229 kit. As a solution, I tried to use the VIOFO A119 Mini 2 camera as a rear camera. It is a nice, fully functional camera, uses the same Sony STARTVIS IMX675 2K sensor as the A229 rear cam, can be purchased on sale well under $100, and works really well, including nighttime operation. It even supports video up to 60fps, better than A229's 30fps. Alternatively, one can consider new affordable 4K cameras from other vendors to further improve rearview image quality. Those interested in long-distance plate capturing may also consider the new VIOFO A329T 2 or 3 channel kit that includes an improved front camera along with the tele-camera (and a rear cam in the 3 channel configuration). I had a very positive experience with VIOFO customer support. My front camera had some irregular start-up issues that I reported to VIOFO. Their representative Freja was very helpful, following up and suggesting firmware updates and various tests. Finally, when the start-up problems became more frequent, she organized free-of charge replacement of my defective camera with a brand new A229 Pro kit, which works great without any issues. As a final note, VIOFO should improve their Windows video player that is barely functional in its current version. It should operate at the same level, as their excellent cameras and the robust phone app. ... show more

I have had and installed several dashboard cameras for my family and I that were in the $150-$250 range. Some worked well, but many were downright lousy (image quality especially!) My brother's car had a $200 one that kept freezing up after about a year, and he got fed up and asked me for a recommendation. I liked my FitcamX for the Toyota Sienna because it had an integrated OEM look. It served me well, but image quality was still lacking despite its 4K video claim. My brother bought the Viofo A139, and it looked pretty good for a 1440-pixel camera thanks to its Sony sensor. I got myself the Viofo A229 Pro 4K to see how it would compare to the FitcamX 4K. For the test, I did not mount it to the windshield and had it lean against the center console instead (see video). PROS - Excellent image quality (some degradation during night time) -- Sony makes some of the best photographic sensors in the industry (I'm a professional photographer but shoot with Canon) -- Better than average night vision that Sony is known for - Can simultaneously record front, rear, and interior with the 3CH version. I bought the 2CH (front, rear) - GPS built in to record place of collision and to log route -- When collision is detected, it beeps a few times. Video is stored in a subfolder on the memory card (forgot what it's called. "Locked"?) - Videos are stored in .MP4 format - Wires are routed through the car's interior and to the cigarette lighter port, but a hardwire kit (to the fuse box is available for purchase) -- Only turns on when the car is powered on, but can also constantly stay on by tapping directly into the car battery (with the optional hardwire kit) -- Cable is USB-A C between cigarette port adapter and main camera, and USB-C between main and rear cameras -- Cables were sufficiently long enough for a Toyota Highlander SUV and Sienna minivan with plenty to spare - Lenses can be rotated to different, vertical angles, but not horizontally - Multiple recording modes in Parked state -- Automatic: when motion is detected, automatically record -- Time lapse at specific frame rates (the higher the FPS, the more images will be taken) ---- Manual warns to use this mode during hot weather to prevent overheating of the camera -- Low bitrate: continuous recording but at a loss of image resolution/quality - microSD memory card support for up to 512GB -- Recommend SanDisk and Kingston the most. Viofo recommends their own branded memory card ---- SanDisk Extreme series cost more, but has lifetime warranty - WiFi function to view via a smartphone app -- Videos can be zoomed into for better visibility - Circular Polarizing Lens (CPL) Filter is an unusual feature -- CPLs are generally used in photography to block out glares and reflections to produce sharper images. Having one for the dashcam can help with that, but that also can create poor images depending on camera angle and time of day. If CPL is used, be sure to check the image quality from time to time - Voice notification to present camera state - Audio recording was decent -- Recording can be turned off for privacy - Manual start/stop of recording via a Bluetooth remote (optional purchase. I did not buy) - GPS coordinate, timestamp, speed, "Viofo" brand, camera model info can be watermarked on/off on the video CONS - Installation manual is better than expected, but if you have installed audio or camera equipment in the car before, it's a straight-forward, standard process -- Installation is made easier with a multimeter if using the hardwire kit. None needed for the cigarette lighter port - A bit on the pricey side - microSD Memory card was not included - 3M sticker to mount camera to windshield could come off over time - Does not look like an OEM camera like the FitcamX does I tested the collision feature by dropping the camera. It made a few beeps and moved the video to a special subfolder on the memory card. You can't go wrong with a Sony image sensor and GPS combination to record collisions. Should they get into an accident or come across a crime, the resulting video will certainly either help put a bad person behind bars and/or safe us much more in insurance cost against false lawsuits caused by fraudulent drivers. ... show more

Good dash cam, but not great.
I purchased one of these along with a wiring kit and memory card, and had it installed professionally. Pros; -The video quality is good, it's not the best you can get but it picks up license plates and other details legibly enough. -It has the option for HDR, you can turn it on all the time or set it to auto. -The setup for its wifi and memory card was painless so long as you follow the steps in the manual. -You can set the recording loops from one to five and ten minute intervals, however you like. And the videos for both the front and back save separately. Cons -The wifi on the front camera doesn't connect to your phone's service. You have to download it and manually connect to it whenever you first start your car and enable the wifi. -It will cost you a couple hundred extra dollars to have it professionally installed so the total cost will be over $500. -The Viofo app you have to use to access videos is slow and not as responsive as other dash cam apps are. Overall I am happy with my purchase, but this camera and setup/access is far from being the best or most responsive. I would put rank this as an upper mid grade quality dash cam, it isn't high grade but it has the potential to save your butt from expensive vehicle repairs or liability. ... show more

Look elsewhere. Horrible app, bad hardware and frustrating to use.
Update 9/5/25: Viofo reached out to me via Amazon messaging where they first offered a refund and then retracted that offer. Instead they suggested the following: "1. About the G-sensor problem, you can try to adjust it to a low sensitivity. 2. About the wifi problem, may I know if you are using the CarPlay? Sometimes the phone will connect to the CarPlay and cause the off connection with the wifi from the dash cam You can check it. Here we have some suggestions for you: Before connecting, you can turn off the mobile cellular data or turn on the flight mode because the phone's signal can sometimes interfere with the wifi connection." I told them that I do not use CarPlay and explained to them that my phone did not disconnect from the dashcam's access point (WiFi) and that the dashcam would simply turn off its WiFi radio, as evidenced by the LED of the far right of the unit turning off. It would do this while I was using the app to search/play back footage, so it was not some sort of idle timeout. As for the app - it is absolutely horrible - just look at the reviews for it in your app store. I use Android, so that is the Play Store for me, where it has a whopping 2.2 stars out of 5. I'll be leaving them well deserved a 1-star review there as well. Viofo seems to be suggesting in their message that all of my issues with their product are to be blamed on my phone. I don't have any trouble connecting WiFi and having a conflict with mobile data being enabled. Since I purchased this product, the price has jumped up another 70 dollars, which I think is quite a premium to pay for a very poor product. At the current price-point, I expect a high-quality, reliable, and user-friendly experience, and Viofo seems incapable of delivering on that. I am returning this item and will try another vendor. Original review: Video quality is acceptable, but that's about where the positives end with this Viofo dash camera. The motion sensor doesn't trigger under hard braking, but will randomly trigger for no apparent reason. The WiFi stability is horrendous and the smartphone app is one of the worst I think I've ever used. It just does not do the job it claims to. This product is insanely frustrating to use. Voice commands don't work. Random conversations might trigger it to take a picture when you don't want it to - or that may have been just the faulty motion sensor - not sure. When the app is connected, it sems like I have about 20 seconds to find a clip I want to download or it will disconnect and I have to try again - holding the WiFi button down again and reconnecting the app, then I have to search AGAIN for the clip I want since it resets to the newest clip every time. And if I do find a clip I want to download, it takes about 15 seconds or so, and if I want to go back and download another, I have to start my search over AGAIN. You are also unable to lock clips through the app to prevent them being overwritten - you have to just rely on the motion sensor to get it right, which in my experience happened exactly ZERO PERCENT of the time. One minute clips are REALLY unwieldy to deal with during a long drive. It's impossible to sort through them all when the clip thumbnails all look nearly identical. This Viofo brand came recommended on Reddit as being the best, but I guess the bar is VERY low. Don't waste your time with this junk. Also, almost forgot - the cables they include are BARELY adequate for my purpose. Routing the power cord under my headliner and down the A-pillar and under the dash left me almost exactly 3 inches to plug into a USB port on my Ram pickup. I guess these are made for compact cars only. I didn't even bother trying to connect the rear -facing camera. Just looking at the cable, I knew I'd come up short. ... show more

Reliability When You Need it Most
(The video I've added was me using my phone to film my computer, so the dash-cam footage is way better in person, trust me) I've had this dash cam for well over a year- it is simply fantastic and well worth the price. If you want a simple dash-cam ready to go with basic plug and play, you can have that. If you want an option heavy dash-cam you can customize to suit your driving needs, you can have that too. It's versatile and stands by its own settings effectively. The video quality and range is great. You will be able to see license plates both day and night from the front or back. This is one of the few dash cams where the footage quality on both the front and rear dash cam are comparable in action and you'll even get a glare lens to help with pesky sunlight. I have a Toyota Corolla and the cables/wires fit comfortably with a little slack so that they can be run wherever you need them to be, so setup and installation is easy and neat. The app is reliable and doesn't have connection issues like my last garbage $300 VAVA dash cam. You will have both your memory card and app for video reviewing or uploading footage. Long story short, if you want an effective dash cam for your front and rear that isn't so cheap that it fails on you in a year and won't connect when you need it, but isn't as expensive as a Garmin or Thinkware high end dash cam, this one is your best bet. Seriously, you won't be disappointed and it will pay for itself in security and reliability. If you don't have a dash cam- GET ONE. ... show more

Excellent dashcam. Great quality. Easy setup and use.
I bought this because it was recommended by The Wirecutter. I'm happy with this purchase. First of all: why buy a dashcam? Well, I previously owned a body cam that I used as a makeshift dashcam. I then got into a crash driving behind a van with their warning lights on for a while. When they slowed down to a crawl, I assumed they would stop and double park, but instead they turned into my car. At first, my insurance company told me I would be 70% responsible, and pay my and their repairs accordingly. But after reviewing the footage and determining how long they had their warning lights on while driving and how slow they were driving, suddenly, my responsiblity was more like 20%. That body cam used as a dashcam paid for instead with one crash! However, of course the quality wasn't that great since it wasn't meant to be a dashcam, and I didn't have a rear camera. So I decided that spending money on a dashcam would be worth it in the event of a crash and would easily pay for itself. I bought the model that comes with a front and rear camera. The quality is excellent, even at night. It's fairly easy to set up using their instructions. I installed the front camera, then ran the wires under the panels of my car to the 12 volt outlet and to the rear camera. The one small downside is that the 12 volt adapter has USB-A outlets, and the cable is USB-C (on the camera side) to USB-A. I don't understand and wish it was all 100% USB-C because that's what I use with all other cables. So I just use this with my existing 12-volt USB-C adapter and use a USB-A to USB-C adapter. In my 2016 Honda Fit, the dashcam turns on automatically when I start the car, and starts recording. There's an iOS app that is decent that I can use to change all the settings, view and download video files. I can set the recording to loop and overwrite the older recordings, and I can even lock certain photo and videos so they don't get recorded over, for example in case of a crash. That lock can also happen automatically based on accelerometer values. This unit also has GPS and can add coordinates and speed to video recordings. Thankfully I haven't had to use the footage for a crash, yet 🤞. I'm pretty confident though that if that were to happen, that footage would be very useful and could be the difference between me paying hundreds of dollars to someone else, and them paying me, and keeping my insurance rates low. I highly recommend this dashcam. ... show more

I purchased this camera as an upgrade from an older single channel only camera and the difference in the quality is almost day and night. This review is a short term one. If things change, I will provide a revision. Among perks of this camera are the contents in the box, physical buttons, high speed memory card support, "live view" in the mobile app, and video quality. The camera comes with cables of sufficient length, extra adhesives, and an easy to understand instruction manual. The box also includes a handy schematic for how to wire the device properly and a plastic "pry bar" type tool to help push the cables behind the interior panels of the vehicle. There's also a 12v two-port USB adaptor but I already have ample USB ports with sufficient amperage built in the car so I opted to not use this one but the inclusion is a nice touch. I mount my camera in front of the rearview mirror where it's out of sight of me while I'm driving. Having physical buttons, especially with the "lock" button being sized larger than the others is a huge benefit for being able to reach over without taking my eyes off the road. Given that this camera can record in 2k in the front and 1080 in the rear, large memory cards are a must and this camera can support a microSD card up to 512gb in size. Aside from the physical buttons, the user interface is great. The various LED indicators seem as if they would be really helpful to indicate to the user what's happening, but as mentioned earlier my use case is a bit different. The voice commands work okay as an alternative to using the buttons, provided there is no music, conversing within the cabin, or road noise. My particular car makes too much road noise unfortunately for the voice commands to work well but other people's experiences may vary, of course. The voice playback when starting, stopping, and performing various other functions on the camera is excellent. The mobile app is available for both Android and iOS devices and has an excellent "live view" feature to help the user with angle adjustments. The inclusion of 5GHz wifi is faster than the traditional 2.4 GHZ spectrum that's included with other models of dash cams. Personally, I just pull the card and place it in an adaptor that connects to my phone when I need to pull footage, but again the option to use WIFI is there and does work, with some patience. The camera writes intuitive filenames which include the year, date, and time, as well as a way to easily differentiate whether the footage is from the front or rear camera. Files that are locked get copied to a separate folder so the user can easily find them. These features make finding a particular bit of footage a breeze. The footage quality itself is excellent, with or without the HDR. Virtually all standard sized license plates are legible in daylight as are most smaller sized plates that are used on motor cycles. Night footage is equally impressive, although sometimes headlight glare overexposes license plates making them difficult to read. The GPS is also an extra touch with the ability to stamp lat and long along with speed in either kmh or mph. The mobile app also allows for some custom fields so someone can add a social media handle, their own license plate, or whatever they desire. ... show more
