In-Depth Video Review

Watch this review in video:


On the surface, the A129 Pro looks identical to the A129. However, the A129 Pro front camera is noticeably heavier than the A129 and that’s because of a built-in cooling system. The A129 Pro is bigger than the A119 by a few millimeters. But just like the two older models, the A129 Pro comes with a 2” HD LCD screen.

Front Camera Video Quality

The front camera is excellent. The lens has an 8.29MP Sony Exmor R Starvis image sensor to deliver crystal clear 4K UHD video quality at 30FPS. Ultra high definition is 4x more vivid than 1080p Full HD and the video recording quality is definitely a much-welcomed upgrade.

Advanced video enhancement technologies including Wide Dynamic Range (WDR) and Super Night Vision, cover a good span between day and night, bright and dark environments to ensure videos are of pristine-quality during the day, and crisp and clear with good definition and minimal noise and blurring at night.

The A129 Pro does have a smaller viewing field at 130-degrees. This is actually 10-degrees less than that of the A129 or the A119. In other words, you are losing about 5-degrees on each side, but in return you get 4x the video quality, so it’s really not a bad trade-off.

Resolution-wise, if you are using just the front camera, your options are 4K at 30FPS or 2K at 60FPS. You can also scale it down to 1080 Full HD at 60 or 120FPS. But if you running the front and rear camera simultaneously, video recording in the front camera is limited to 30FPS.

Another upgrade we see in the A129 Pro is the additional bitrate options. With the A129 and A119, you were limited to just high or low bitrate. But with the A129 Pro, you can choose from 4: Low, Medium, High and Maximum.

Here’s a comparison table for a 1-min video in 4K at 30FPS:

Overall Bitrate

Video File Size


15.3 Mb/s



30.3 Mb/s



42.4 Mb/s



60.3 Mb/s


Rear Camera Video Quality

The A129 Pro uses the same rear camera as the A129. The rear camera is equipped with a 2.13MP Sony Exmor R Starvis IMX291 image sensor to deliver Full HD recording at 30FPS.

If you are looking for an IR camera for the A129 Pro, do note that VIOFO has not released any A129 Pro Duo IR camera. However, the A129 IR camera is compatible with the A129 Pro. In other words, if you have the A129 IR camera, you can simply plug it into the A129 Pro with the existing IR camera cable.

Parking Surveillance

While VIOFO was able to deliver a true 4K UHD dash cam that rivals that of the premium name-brands, such as the Thinkware U1000, it lacks the advanced parking capabilities. Parking mode is definitely one of the weaker areas of the VIOFO A129 Pro. There are 3 options under parking mode: Auto Event Detection with Buffered Parking Recording, Time Lapse Recording and Low Bitrate Recording.

With buffered parking recording, the camera will automatically record a video sequence (from 15 seconds before the event to 30 seconds after the event) if the motion detectors are triggered. If no further motion or impact was detected for 60 seconds, the camera will stop recording and returns to a standby mode until the next time motion or impact is detected.

With the new advancements in parking mode features in the market, what the A129 Pro offers is relatively elementary, especially when the Thinkware U1000 offers the option of ultra -high frequency radar motion detection with the optional add-on RADAR module.


4K dash cams are more susceptible to overheating in hot weather, especially when used for parking mode inside a roasting car at mid summer. As we mentioned earlier, the A129 Pro has a built-in cooling system. The A129 Pro has an operating temperature of -10-degrees to 65-degrees Celsius, so it is built to withstand the hot southern summer days.

And like other premium dash cams on the market, the A129 Pro uses supercapacitors instead of lithium batteries. Unlike batteries, supercapacitors won’t expand or explode under high heat, making the A129 Pro a reliable dash cam under high heat. Another benefit of using a supercapacitor is, in the event of a sudden loss of power, such as a collision, the supercapacitor will provide enough power so that the recorded file may be saved on the memory card before the camera powers down.”

GPS Built-in Mount

The A129 Pro available on BlackboxMyCar comes with the external GPS module. With the GPS, you can record your speed and route data in your video footage files. The GPS will also synchronize the A129 Pro’s clock with the GPS time so that your video files can be correctly time-stamped.

Connecting to the Dash Cam

Just like the A129, the A129 Pro is a dual-band WiFi dash cam and with the additional 5GHz frequency, you can get faster data rates at shorter distances, making it perfect if you need to download multiple footage files when you’re home.

It has been reported that the 5GHz WiFi on the A129 Pro is significantly faster than that on the A129. The A129 Pro’s typical transfer rates were about 8-10 Mb/s while the A129 often only manages 1-2 Mb/s, depending on the device it’s talking to.

To connect to dash cam, you will need the VIOFO mobile viewer app, which is available free on the Apple App Store and the Google Play Store. Using the mobile viewer app, you can get real-time video preview, download and travel data right on your smartphone. Alternatively, you can use the 2” HD LCD screen for easy setup and video playback. This LCD screen is the same as the one on the A129 or A119.

The A129 Pro does not offer any Cloud capabilities.

Saving Video Footage

4K video files are known to be larger in size and as a solution, the A129 Pro comes with the H.265 High Efficiency Video Coding technology. This is the same encoding technology found in the BlackVue DR900S 4K dash cam. With the H.265, 4K videos can be compressed to the size of a Full HD video file.

However, the downside of H.265 is difficulties on playback since many devices will struggle with high bitrate 4K encoded in H.265. The standard H.264 video compression is available and is still the default compression method on the A129 Pro.

Note that the A129 GB does not come with any stock microSD card, so you will need to pick one up at checkout. But because of the larger file size, you may want to consider getting a higher capacity memory card. For instance, say you are going to be using the highest front and rear recording settings, a 128GB car will only supply about 3.5 hours of footage. The A129 Pro supports up to 256GB.


If you are upgrading to the A129 Pro from the A129, please note that:

  1. The A129 Pro Rear Camera is the same rear camera as the A129, which means if you already have the A129 Rear Camera installed in your vehicle you can simply plug it into the new A129 Pro Front Camera if you wish to leave your current rear camera setup intact.
  2. If you are looking for a temporary mount for the A129 Pro, please note that the A129 Suction Cup Mount will not fit the A129 Pro. VIOFO has not yet released any temporary mount solutions for the A129 Pro.

Also because the A129 GB does not come with any stock microSD card, so you will need to pick one up at checkout. The A129 Pro supports up to 256GB and we recommend getting the largest capacity memory card because 4K video files are known to be larger in size.

Who Should Choose the VIOFO A129 Pro

The VIOFO A129 Pro will make a lot of sense for a lot of different types of drivers.

For those who demand the best recording quality: We're talking about 4K Ultra HD. While the rear camera is only giving you 1080p Full HD, the front camera delivers a solid 4K Ultra HD recording quality. With impressive night vision and exposure correction features, the drive ahead of you will be captured in crystal-clear, movie-like quality.

For those who prefer a built-in viewing screen: If you do not have a smartphone or prefer not to use a mobile viewer app, having a screen onboard will provide you with an easy way to setup your dash cam as well as let you see the footage you’ve captured. However, do keep in mind that the LCD screen adds size to the dash cam, and ultimately, makes the entire setup bulkier. If discreteness is important to you, we recommend getting a screen-less dash cam.

For those who want dual-band WiFi support: At this time, the VIOFO A129 Pro and the BlackVue DR900S are the only two 4K UHD dash cams that offer dual-band WiFi support. If 4K recording capabilities plus dual-band WiFi is important to you and you are looking for a lower-cost alternative to the BlackVue DR900S, then the VIOFO A129 Pro would be a good option.

Final Verdict

The A129 Pro is a great 4K dash cam, delivering pristine video quality. The A129 Pro is more than just an improved A129.

Although the A129 Pro lacks the advanced parking mode features and cloud capabilities that the Thinkware U1000 and BlackVue DR900S offer, it has exceeded our expectations on many levels. The A129 Pro is an ideal dash cam system for those who would like to experience 4K UHD recording but prefer to have the convenient control of a screen and does not require advanced parking surveillance

VIOFO A129 Pro Duo Review

Based on 4269 reviews
Very Good - not yet great. But getting there.

I purchased the BlackVue DR900S 2 channel with interior facing IR after an attempted theft of my 2019 F-150 Lariat. It was already a purchase I had been considering in order to add a layer of security during both active and passive vehicle usage and I didn't hesitate to go with BMC given the number of positive reviews.

After a fast and painless exchange via email, BMC matched a lower price point offer for the kit that I had found on the internet. BMC even included a slightly larger storage card. Shipping and receipt went smoothly.

If I can fault BMC it is in the install and "commissioning" of the dash cam. Though I had done a fair bit of research and certainly am not one to shy away from peeling off some trim or crimping some wires, there was no step-by-step guide to installation that would have given an illustrated and comprehensive explanation of the process; now, this information exists and I was able to access it, but it was still a bit of a patchwork construction and an installation that I thought might take one hour took 2 days.

All said, though, the system is now up and running, so far flawlessly, in my vehicle. There has been a lot of trial and error, but the dash cam community is helpful and all of the information is available. You just need to look for it.

I will post a video review of my installation shortly - including hardwired battery installation.

Hi Alexander, thank you for leaving a review! We're glad to hear that we were able to help you with your order. You brought up some great points, and we will definitely take your feedback to heart for the future. We hope that the dash cam works out for you. Please let us know if you have any questions in the future.

BlackboxMyCar Add-A-Fuse Kit

Hi Brian, thanks for leaving a review!
VIOFO A119 12V Auto Hardwire Kit

Quality hardwire kit with reasonable length to the A119 and to the 12V battery source. Voltage reducer is small enough to fit in small spaces with rounded corners for ease of fishing into place. Fuse holder streamlined but difficult to open at first, 2nd time ok.

Hi Chester, thanks for leaving a review! Glad to hear that you were able to figure it out and install your VIOFO. Let us know if you have any questions. Thanks!

Suction Cup add-on

I bought this suction cup mount to move and use quickly my A119 V3 from vehicle to vehicle.
After receiving I must say its smaller and lighter than expected compared to the picture but still functional and we will see how long the suction cup lasts over time.
I also saw a video of using this suction cup to turn the A119 around and take video of driver with commentary about area or something else which I plan to edit into my video at a later time.
So its a nice feature for the video I plan to make while on vacation.

Hi John, thanks for your feedback. Let us know if the suction cup mount doesn't work well for you over time and we'll try our best to help. Thanks!
Blackbox My Car is the Best!

Sorry BB team for taking so long before writing a review, but the 2 Viofo a129 duo dashs were xmas gifts and I wanted to wait for your professional installations to be done first.
I have purchased dascams from BB before and have had nothing but a great experience for both service and products.

Both Viofo cams are working great and the installation service was the best. The team was awesome and answered all my questions without hesitation. Your waiting area and amenities are first class. Most car dealerships could learned a thing or 2 from how you operate!

Thank you again!

Hi Ken, appreciate your compliments and thank you for leaving a review! We're glad to hear that you enjoyed our facilities and that the installation and the dash cams worked out for you. If you have any questions, please don't hesitate to reach out at any time in the future!
Very pleased with the A119V3 and with customer service

After researching a number affordable dash cams I settled on the Viofo A119V3 and Blackboxmycar as the vendor. I chose Blackboxmycar because of its customer service. This is my first Dashcam and I had a number of questions all of which were answered promptly and to my satisfaction by Katrina. Other vendors offered a slightly less expensive final cost but Katrina's service swayed my decision.

As to the camera itself I am very happy. In the last few days I have used it in temperatures of about -28ºC and it has performed flawlessly. The video quality is excellent with the CPL: clear, sharp and with good colours and contrast. Files are around 1.15 GB for 5 mins using 2560x1440 @30 fps H.264 or around 950 MB using H.265. The audio quality is quite acceptable.

Once you get the hang of using the Menu system it is quite easy to choose or change settings.

Also impressed with Viofo in that they seem to have thought of everything. The item included everything I could possibly need to mount and operate the camera even down to string to help remove the mounts in future if necessary.

Presently I am powering the camera via the cigarette lighter but am seriously considering hardwiring or using a portable power bank. I will then try the parking modes.

We have two cars and I had thought of moving the camera from one to the other so I purchased an additional GPS mount, that I have not yet tested. However I am now leaning towards buying 2nd A119V3 to avoid the hassle and to have a permanent neat installation in both cars.

Hi David, thanks for leaving a review! We're glad to hear that Katrina was able to help you out, and that the VIOFO A119 V3 was exactly what you were looking for. If you need anything else, please don't hesitate to let us know!

Best Site for the Best Dashcams Around

My 2nd purchase from Alex and 2nd Blackvue camera purchased. Blackvue is my favourite dashcam because of its sleek and unobtrusive design and extremely high quality recordings. Easy to download recordings with the app now, will continue to recommend Blackvue's to everyone.

As for, great selection of the best Dashcams out on the market. Extremely informative website with an abundance of information and comparisons to make the right choice. Fast shipping and great customer service, this is the way to go to buy a dashcam over the cheaper but inferior choices on Amazon or anywhere else.

Hi Wesley, thanks for your review. We're glad to hear that you're loving your BlackVue dash cam as much as we do! Hope the DR590W-1CH treats you well :) If you have any questions, please don't hesitate to reach out to our team.

1st time buyer from

Review Title
I have done a lot of research on finding my second dash cam and decided on a VIOFO A119 V3.
I have seen some video of reviews of the camera and compared to my 1st Dash Cam A119S V2 and figured that VIOFO was a good choice again. I have seen Alex the CEO of BlackBoxMyCar do a review video on the A119 V3 in 2019 and went to his website and decided it was very professionally designed and easy to use. Not only did I buy the camera I found some accessories.
I ordered then noticed they offered first responders and military a discount and sent an email if I could get this discount. Quick email reply from Paul who I sent documentation on proof and he who forwarded my request to get a refund on my purchase. Thank you.
Now I did order my camera knowing it was back ordered as well as this was Christmas and New Years week so I wasn’t expecting to see the camera until Jan 2020.
It did arrive in a box and was properly packed. I had numerous email from FedEx where my package was and when it would arrive and someone must be home to signature for it.
Between the initial purchase and receiving my dash cam BBMC has been above and beyond what I expected and under the leadership of Alex I see why this company is so successful.
Thank you everyone for a great purchase and plan on additional future purchase from me.

Hi John, thank you for the kind words and the detailed review. We're glad to hear that we were able to help you find what you're looking for. We will pass on your compliments to Alex who will absolutely be delighted to read this. Thanks again, and do let us know if you have any questions.
Delivery Needs To Be Improved

I ordered it on Dec 28 with Rocket shipping and it arrived Jan 6 but I had to constantly contact them about the status of the order as it was stuck for many days with no updates. I give this service 1 star. The product itself is excellent, well made (except the App), easy to install, etc which deserves 5 stars. Overall 3 stars.

Hi Bill, thank you for leaving a review. We do want to apologize for that, and thank you for your patience. This holiday season was quite a busy one for our team, and we had some inventory delays with the unexpected surge in demand for our battery packs. We are working on smoothing that out moving forward so that we don't have this happen again. From a communication standpoint, we will absolutely work on fixing that moving forward to make sure our customers are aware of any delays. We apologize for the inconvenience. Thank you for purchasing from BlackboxMyCar, and if you have any questions, Bill, please don't hesitate to reach out to our support team.
Great for extended parking mode!

Before purchased and installed the Cellink Neo I was using my Thinkware Q800Pro hardwired to my car. However, my vehicle stays parked for days on end without me having to drive anywhere. I get about 40 hours with a dual camera setup, and I couldn’t be happier to have an extra piece of mind. The installation was very easy, as I did it myself (hardwired) and mounted it under the driver seat. This would be a worth while purchase.

Hi Brandon, we're glad to hear that your new battery pack worked out for you! If you have any questions, please don't hesitate to contact us in the future.

Although my dash cam was on a backorder after Christmas, it delivered right the way I wanted it. I like the dash cam is tiny. The video is very clear.

Hi John, thank you for leaving a review. We had some inventory delays during the holiday season with the unexpected surge in demand for our dash cams, but we're glad that we were able to deliver your dash cam in time. Thank you for purchasing from BlackboxMyCar!
Great product to reduce glare!

Does what it says to reduce windshield glare, it’s easy to install

Hi Brandon, thank you for leaving a review! If you have any questions, please don't hesitate to contact us in the future.
Amazing Product - Worth Buying

This product helped hardwiring my dash cam so much easier as there were no wires that needed to be spliced. The trim tool made it convenient to tuck the wires inside the car and only show minimal wires. All in all, this all-in-one kit, made hardwiring my dash cam so much easier.

Hi Sai, thank you for leaving a review and for shopping at BlackboxMyCar. Glad to hear that this worked out for you. Please don't hesitate to reach out to us in the future if you have any more questions.
