About this item

  • 【3 Channel Dash Cam】 The A139 comes with front camera (140°), inside camera (170°), and rear camera (170°) to simultaneously record videos at 1440P+1080P+1080P @30fps.You can install it anywhere because it has two independent interior and rear cameras.
  • 【Super Slim Coaxial Cable】 The interior and rear interconnects on the A139 Dash cam 3 channel are made with super slim coaxial cable and miniature connectors, making installation easier and more discrete than with traditional cable types. Also reduces noise disturbance to the car.
  • 【Built-in 5GHz Wi-Fi & GPS】 The Wi-Fi connection and VIOFO mobile app give you access to settings, a live view of the front inside rear dashcam, recorded video playback, and the ability to download/share video files. The triple channel dash cam can log the current speed and GPS location using the GPS logger, and a time stamp can be embedded in the video.
  • 【Anti-Glare CPL Included】 The CPL (Circular Polarizing Lens) is attached to the dashcam's front lens to reduce reflections and glare from glass and road surfaces, resulting in significantly improved image quality and contrast in many situations.
  • 【Voice Notification】 When you set the car camera or the camera encounters an error while recording, it will speak in English to remind you of the camera's status, assist you in properly completing the setup wizard, and diagnose issues; don't worry if it stops recording without informing you.

    Great product and a review for you!!
    Hi, I've been a bit of a VIOFO fanboy for some time now and really wanted to do a review on their latest product, the A139. I switched to VIOFO several years ago and I have never had an issue with their equipment. I have the A119S, A119v3 (latest in this series), the A129 Duo and just purchased the A139 3channel. So I have a lot of experience with their products. This review will be on the A139 3ch, their latest system and even though I have a lot of their stuff I will remain unbiased. So lets begin!Packaging of all of their units is pretty straight forward and polished. All items needed for installation are included in the box (even a pry tool for trim removal). The only thing missing in this model that they include in others are the 5 wire clips. Luckily I had some left over from a previous installation. It includes an actual manual that is in perfect English and easy to read (no micro print). It shows detailed pictures and defines each of the settings that the camera is capable of. All of their systems have options so when purchasing make sure you read the description of those to see if you want them. This system came with the CPL filter for polarization. IMHO this is a must and shouldn't be an option in any of the cameras they sell. It greatly cuts down on sun glare and I was happy to see that it is standard in this edition. The system does not come with a microSD card. It does support up to 256GB and I solely use the Samsung Pro Endurance models that are made for these types of devices. The front facing camera has the Sony IMX335 5mp sensor while the two other cameras have the Sony Starvis IMX291 sensor. This gives you 2k video out the front and 1080p for the interior and rear. 1080P is ok however, I would like to see the same Sony 5mp sensor used for the rear camera but that's just me and may be a limitation to the recording processor in the unit due to 3ch recording. Even the A129 Pro Duo which has 4k front sensor recording still has the 1080p rear. If someone rear-ends you then they will be close so hopefully it will adequately record their tag number. All of these systems video quality is superb during the day, the real deal is at night. Night time video still produces adequate footage however, tags and intricate detail become washed out at distances. Adding motion will also blur these. Closer view are still good though. I will include some day and night pictures and footage but remember that Amazon compresses the videos somewhat so the quality will not be as good as the original footage.Installation is pretty easy as well. Just figure where you want to mount the cameras and do a dry fit of cables for length to make sure everything will fit and reach where the final installation takes place. I like to install the main unit behind my rear view mirror on the passenger side of it so as not to distract me. When mounting the unit and cameras, clean the glass with alcohol patches first and make sure temp is above 60F for proper adhesion. I use 3M Dual Lock myself, it makes it easy to remove the units and locks tight when in use. Google it you'll love it. I installed this one in my 2020 Jeep Wrangler. All wiring was long enough and I ran into no issues. I had a long explanation and a gripe on the camera wire connector attachments but then I realized I was not pushing hard enough. This connectors needs a firm push until it snaps with the knurled barrel becoming flush with casing. The new cables that they use to connect the cameras are thin, durable and easily fished through the trim molding to their final destination. One recommendation I have for the company is to make the camera that shows the interior able to turn towards the drivers side window to capture interactions with police or others. This could also be easily achieved by having a small stiff hinge on the mount that allows you to turn the camera 90 degrees towards the drivers window and a magnet built in to keep it in place for normal interior recording, just a thought. This unit does not have a LCD screen and all video is previewed via wireless connection to your cell phone and their app. Touching on that, they support both 2ghz and 5ghz Wi-Fi and I found the app easy to install, sync and navigate. With the unit powered in my vehicle in the driveway I can access the cameras and video from inside my residence. I like this for those bumps in the night and wanting to check those cameras. I also see on this model that they have finally went to USB-C connections! Although my other units did not have any issues with the older style USB connectors I like the newer connections for durability and data transfer speeds. All of my units have the GPS logging capability. I found that the speeds where correct and like the ability to have this as an overlay and turn it on or off. Both KPH and MPH are available as well. All units record sound and this too can be turned off or on. This unit has the option of an external microphone as well. I don't utilize this feature but it could be useful in the right situation. They have another option of the Bluetooth button that you can mount anywhere in your vehicle and when pressed it will start recording and create a protected event. I wish it came with this standard as I really see this as a positive for certain situations as well. A panic recording switch if you will.I used a 256GB card in my unit. The card needs to be formatted in FAT32. This can be accomplished through the app or by using the include card to USB adapter and your computer. A note in the directions says to make sure the unit is off before removing and installing the SD card so that it does not become corrupted. The camera uses a decent amount of power to run. The cigarette adapter shows 12v 3A so definitely need to make sure its off when the vehicle is off or utilize a separate battery system for powering when the vehicle is off. They make a wiring harness for this the HK3-C hardwire kit however, I don't know what kind of strain this would case on the vehicles battery while not running.Navigating the menus and setting up the app was easy. Remember that the initial process is to hold the WiFi button until the blue light is on and the voice says “WiFi on” as well. Then go to your wireless settings and join the one for Viofoxxxx. The default password is 12345678 and can be changed along with the SSID being broadcast. Once connected start the app and you will be good to go. Mine did not need much tweaking from factory defaults. I did set my resolutions to the max and turned on WDR. This stands for Wide Dynamic Range and is used for glare and to make dark and light scenes show more equal. For instance, going through a tunnel and the light at then end doesn't wash out the picture as you approach and the camera iris hasn't adjusted yet.Once logged in you are presented with a screen that shows all three camera views live. I really like this and wish that the camera offered this feature when saving the video off and playing it back. Currently it saves each camera as a separate video file and you would have to use a third party video software to piece them all together for simultaneous playback. Not a deal breaker for me just another thought for the company to incorporate. Maybe a firmware update? So in closing I think they have another great product here. This system would be especially useful for Uber/Lyft drivers or Vloggers or anyone wanting a polished well thought out system that's easy to install and should last the owner a long time. I forgot to mention that it has super capacitors for storing the last video clips if it the power goes out. These are a must and I can't believe some companies are still putting batteries in them. They get hot on your windshield and the batteries will swell and destroy the system eventually. None of that happens with VIOFO units because they use the super capacitors instead. A final note, the unit comes with a 12 month warranty and you get an additional 6 months if you register the product on their website. I have had great feedback and quick responses when dealing with their support as well. If you got this far then please take a minute and look at the video I included along with pictures. I don't think you will be disappointed with this system, I love mine.
    Thank you for your feedback

Although my other units did not have any issues with the older style USB connectors I like the newer connections for durability and data transfer speeds. All of my units have the GPS logging capability. I found that the speeds where correct and like the ability to have this as an overlay and turn it on or off. Both KPH and MPH are available as well. All units record sound and this too can be turned off or on. This unit has the option of an external microphone as well. I don't utilize this feature but it could be useful in the right situation. They have another option of the Bluetooth button that you can mount anywhere in your vehicle and when pressed it will start recording and create a protected event. I wish it came with this standard as I really see this as a positive for certain situations as well. A panic recording switch if you will.

    I used a 256GB card in my unit. The card needs to be formatted in FAT32. This can be accomplished through the app or by using the include card to USB adapter and your computer. A note in the directions says to make sure the unit is off before removing and installing the SD card so that it does not become corrupted. The camera uses a decent amount of power to run. The cigarette adapter shows 12v 3A so definitely need to make sure its off when the vehicle is off or utilize a separate battery system for powering when the vehicle is off. They make a wiring harness for this the HK3-C hardwire kit however, I don't know what kind of strain this would case on the vehicles battery while not running.

    Navigating the menus and setting up the app was easy. Remember that the initial process is to hold the WiFi button until the blue light is on and the voice says “WiFi on” as well. Then go to your wireless settings and join the one for Viofoxxxx. The default password is 12345678 and can be changed along with the SSID being broadcast. Once connected start the app and you will be good to go. Mine did not need much tweaking from factory defaults. I did set my resolutions to the max and turned on WDR. This stands for Wide Dynamic Range and is used for glare and to make dark and light scenes show more equal. For instance, going through a tunnel and the light at then end doesn't wash out the picture as you approach and the camera iris hasn't adjusted yet.

    Once logged in you are presented with a screen that shows all three camera views live. I really like this and wish that the camera offered this feature when saving the video off and playing it back. Currently it saves each camera as a separate video file and you would have to use a third party video software to piece them all together for simultaneous playback. Not a deal breaker for me just another thought for the company to incorporate. Maybe a firmware update? So in closing I think they have another great product here. This system would be especially useful for Uber/Lyft drivers or Vloggers or anyone wanting a polished well thought out system that's easy to install and should last the owner a long time. I forgot to mention that it has super capacitors for storing the last video clips if it the power goes out. These are a must and I can't believe some companies are still putting batteries in them. They get hot on your windshield and the batteries will swell and destroy the system eventually. None of that happens with VIOFO units because they use the super capacitors instead. A final note, the unit comes with a 12 month warranty and you get an additional 6 months if you register the product on their website. I have had great feedback and quick responses when dealing with their support as well. If you got this far then please take a minute and look at the video I included along with pictures. I don't think you will be disappointed with this system, I love mine.

    5.0 out of 5 stars High quality construction, excellent video, well supplied for quality instruction.
    Reviewed in the United States on April 7, 2021
    The items included in this package really lend themselves to a high quality installation. The photos I have attached will display the obvious things, but what I would like to point out in particular are the Static Windshield Film patches that are included. At first I did not quite understand what they were for, because this product was unfamiliar to me and the instructions could have been written a little better, but basically, these patches get attached to the clean windshield and then the 3M stick pad, attached to the cameras, are stuck to the static patch. This is brilliant, because it allows the camera to be removed and relocated. While I would not recommend doing this to often, as it may reduce the effectiveness of the static patch, it does allow you to tweak things. What a great idea! An extra set of 3M adhesive pads are included.

    The camera itself appears to be constructed very well. I have had other dash cameras in the past, and the VIOFO 139 definitely trumps the quality of those. In particular, the connections for rear and inside camera are very precise and have definite “click” when they are connected. The cable included in the kit has been updated from the previous VIOFO dash cameras, and it is smaller in diameter. I found it very easy to tuck it away, inside the moulding of my car. The trim removal tool included in the kit was very helpful.

    It took me about 2 hours for the complete installation. I took my time, and the end result looks very clean. The camera and main housing themselves are wedge shaped. This allowed me to tuck it up, under my rearview mirror. It is out of sight, yet assessable should I need to get to it. The lens itself rotates up and down for any angled windshield. My car is a 6 series BMW, and it fits great.

    Since there is no display on the camera itself, the app, available through the App Store or Google Play store, provides most of the interaction with the camera via its own Wifi. I prefer using the app over fiddling with the camera, as it is tucked out of the way. The settings tab in the app has numerous settings/configurations, some of which I used, other that were of little interest to me at this point. Those folks who love to mix things up would probably dive into the options more than I did. Notable configurations are:

    1) You are able to flip the camera view. This allowed me to really find the best location
    during installation for the rear and interior cameras (cable access from either side).
    2) Screen Shot-take a photo from one of the recordings.
    3) Turning off sounds when pushing buttons on camera or turning camera on.
    4) Turn off the audio when the camera is recording. In the event of an incident, I really don’t need the camera to record what I have to say (probably would work against me).

    Overall, the app has functioned very well. There have been a few times where it would disconnect from the camera, but I was easily able to re-acquire it.

    So far I have recorded a couple of hours of video. I purchased a high quality 128 GB Micro SD card. Rather than use my iPhone to view and download the videos, I have used my iPad. The video quality is stunning. Both my son and wife are amazed. Like I said earlier in this review. The quality of this camera verses lesser dash cameras, is stunning.

    There are several accessories available for this camera, which you can find on the VIOFO product site. In particular, I would like to get the Hardwire Kit (HK3-C). This allows the camera to operate even when the vehicle is turned off, getting power to the camera via the fusebox of the car. If your cigarette lighter plug is always powered, then this is not an issue for you. Mine turns off after a preset period after turning off the car. This kit is currently unavailable through Amazon. I hope it becomes available.

    Having this camera gives me peace of mind. I know that in the event of an incident, I will be well protected. As I become more accustomed to this camera, I will update this review as needed. I highly recommend this dash camera system.

    5.0 out of 5 stars 3-Channel Dashcam - A Seamless Experience for Novices and Excellent Video Quality
    Reviewed in Australia on July 22, 2023
    I recently purchased a 3-channel dashcam, and I must say, it has exceeded my expectations in both video quality and ease of installation. As a person with no prior experience in installing dashcams, I was pleasantly surprised at how user-friendly this device proved to be.

    First and foremost, the video quality is outstanding. The dashcam records in QHD and HD, capturing crisp and clear footage of the road ahead as well as the surroundings on either side. The three channels provide comprehensive coverage, ensuring that no critical event goes undocumented.

    What truly impressed me was the simplicity of the installation process. With minimal guidance from the manual, I was able to set up the dashcam in my car within a matter of minutes. The adhesive mounts securely held the cameras in place, and the cable management system was intuitive, keeping the interior of my vehicle neat and tidy.

    Moreover, the dashcam features a loop recording function that ensures continuous recording without interruption. In the event of a collision or sudden impact, the built-in G-sensor promptly locks the footage to prevent accidental deletion.

    The dashcam's compact design is unobtrusive and blends well with my car's interior.

    Overall, I highly recommend the 3-channel dashcam to anyone looking for a reliable and user-friendly device with excellent video quality. Whether you're a seasoned driver or a novice, this dashcam provides peace of mind on the road, capturing crucial evidence in case of any unforeseen incidents.
