Let’s get started.
Overview of the Viofo A139 Pro Dashcam
The Viofo A139 Pro dashcam is uniquely designed and built with all of the latest technological features you expect to get in a dashcam. It is worth mentioning that the Viofo A139 Pro dashcam has a predecessor which is the Viofo A139. The predecessor has the exact same shape as the Pro version. It is a 2K dashcam with 3-channel support and uses the original Sony Starvis Image Sensor. Also, the interior and rear cameras that come with the predecessor model are the same that you will get with the Viofo A139 Pro version (3-channel package). So, if you already own the predecessor model and would like to go for the Pro model, you could purchase only the Viofo A139 Pro Front Camera.
The Viofo A139 Pro dashcam comes in four setups. The first is a 1-channel setup where you may need just the front-facing camera. The second is a 2-channel setup with the front-facing camera and the rear-facing camera. The third is also a 2-channel setup with the front-facing camera and the interior-facing camera. Then, the fourth is a 3-channel setup that includes the front-facing camera, rear-facing camera, and interior-facing camera.
Taking a quick look at the Viofo A139 Pro, at the very top are six ports. From left to right you have an AV Output Port, an External Microphone Port, a Screw Hole, the Rear Camera Port, the Interior Camera Port, and a USB-C Power Port. Then on the right-hand side, you have a Screw Hole, a MicroSD Card Slot, and the Lens (rotatable). On the lens is a white line, and this line is there to guide you when using the Polarizer. This Polarizer is a protection that you affix to the Lens to prevent sun rays or reflections from your windshield.
On one side of the Viofo A139 Pro, you will observe five buttons and four LEDs. From left to right you have a Power button to turn the device ON or OFF, then a Start/Stop Record button, an Emergency Record button, a Microphone ON/OFF button, and a Wi-Fi ON/OFF button. On this side of the A139 Pro, you will also find the loudspeaker. Then on the other side of the device, you have a Quick Release Mount.
Features and Performance of the Viofo A139 Pro
The unique selling point of the Viofo A139 Pro dashcam is its Sony Starvis 2 Image Sensor, and it is the first to have a Sony Starvis 2 Image Sensor. Sony Starvis Sensors are loved for their remarkable low-light performance and exceptional daytime video quality.
The Sony Starvis 2 is the latest improvement to these, along with improvements in the Sensitivity to Infrared Light, Blur, Noise, and High Dynamic Range. Being a more sensitive sensor, it delivers faster shutter speeds that you can rely on compared to freeze frame action. Also, it delivers accurate image captures irrespective of changes in lighting which is very helpful at night. However, note that the Sony Starvis 2 Image Sensor is built into the Viofo A139 Pro’s Front Camera only. The interior and rear cameras record in 1080p.
With the 3-channel setup (Front Camera, Interior Camera, Rear Camera), the front camera cannot record in full 4k 2160p at 30fps, it can only deliver in 4K 2160p @ 24fps, and the other two cameras record in 1080p @ 24fps. There is a second option where it records in 4K 1600p @ 30fps but this means the top and bottom of the view will be a bit cut off; the other two cameras will record in 1080p @ 30fps. Thirdly, you can get 30fps 1440p but in 2K, and the other two cameras will deliver in 1080p @ 30fps. If you are going to be using the 3-channel setup, these are settings you would have to play around with to find what works best for you.
If you opt for a 2-channel setup (Setup 1), (Setup 2), this will include the front camera and the rear camera only, or the front camera and the interior camera only. Now, whichever 2-channel setup you choose, in the first mode, the front camera will deliver 4K 2160p @ 30fps, and the second camera in 1080p @ 30fps. The second mode you have is that the front camera will deliver in 4K 1600p @ 30fps and the second camera in 1080p @ 30fps. Thirdly, with HDR Turned OFF, the front camera delivers in 2K 1440p @ 60fps and the second camera in 1080p @ 30fps. Fourthly, with HDR Turned ON, the front camera delivers in 2K 1440p @ 30fps and the second camera in 1080p @ 30fps.
Furthermore, a 1-channel setup includes only the front camera. With this, you have the first mode where the camera records in 4K 2160p @ 30fps. In the second mode, it records in 4K 1600p @ 30fps. Thirdly, with HDR Turned OFF, it records in 2K 1440p @ 60fps. Fourthly, with HDR Turned ON, it records in 2K 1440p @ 30fps. Overall, the Viofo A139 Pro produces very impressive images, videos, and does remarkably well with number plate recognition.
Another unique feature of the Viofo A139 Pro dashcam is its Parking Recording. Firstly, you have Automatic Event Recording whereby recording takes place by motion detection and sudden changes such as a collision. Also in this mode, the dashcam performs continuous recording such that you have Pre and Post recorded footage of events or bumps to your vehicle. Secondly, you have Time Lapse Recording with the dashcam’s ability to choose how many frames it takes per second. The third option is Low Bit Rate Recording whereby the dashcam reduces the bit rate so that recorded files are smaller. It also records traditional videos with audio recordings as well.
GPS Logger is obviously a feature you have with the Viofo A139 Pro dashcam. This provides you robust tracking data for all movements helping you to optimize routes and also enhance safety and security.
