Why Do You Need A 2K + 2K Front And Rear A229 Duo Dashcam?

17th August, 2022 | Dashcam

Since 2011, VIOFO has always been striving to enhance the image quality of dash cameras, covering all three channels, front+interior+rear. It is well known that the T130-3CH released last year greatly improves its night vision for interior recording enhanced by the newly adopted OV image sensor integrating ultra-low light and near-infrared technology.


This year VIOFO has reached new heights in A229 Duo rear camera’s resolution. As the upgraded version of the A129 series, this new generation A229 Duo dashcam innovatively features up to Quad HD 2K high-resolution rear cam, the highest so far in the market for rear recording to give you enhanced driving safety protection from not just the front, but also behind.


What else do we have to learn about this newly released dashcam? Check it out below:


2K+2K Front & Rear QHD Recording

A229 Duo supports Quad HD 1440P30fps front + Quad HD 1440P30fps rear recording. Some drivers say that tailgaters tend to back off when they spot a rear-facing dashcam installed on the car in front of them, making rear-end accidents less likely to happen. Now with a 2K high-res rear camera, you can easily capture license plate numbers even if you’re caught in an accident that takes place behind you, or provide evidence if another car is harassing you on the road. The built-in F1.6 aperture lens and WDR technology are also of great assistance to shoot more detailed images both day and night.

2.4 Inch HD Screen

Different from the VIOFO conventional 2-inch screen, the A229 Duo dash camera is built with a larger 2.4-inch HD display which delivers a more direct effortless live view and improved performance in heat dissipation and better durability. In addition to” REC”, ”MIC”, and “Wi-Fi”, two new LED indicators, “PWR” and “GPS”, have been added to the front panel to help you easily catch the status of the cam and the functions enabled.

Neat Installation with 2.8mm Slim Coaxial Cable

The A229 Duo features a premium compact design utilizing a 2.8mm super slim coaxial rear cable and miniature connectors for neatly hidden installation, making it more user-friendly for beginners. What’s more, the newly upgraded coaxial cable enables better electromagnetic interference reduction than traditional cable types.

USB-C Charging Cable & Power Ports

To accommodate more car models with different installations, the A229 Duo is equipped with a reversible USB-C charging cable and two USB-C power ports – one on the left side of the front cam and one on top of the GPS module. Compared to micro USB cables, USB-C cables can carry more power and reliably offer a more stable power supply.

Tips: The GPS module will function normally regardless of which power port is used for the power supply.

Dual Band 5GHz & 2.4 GHz Wi-Fi

The A229 Duo dashcam supports dual-band Wi-Fi options of 5GHz & 2.4GHz. A Wi-Fi connection makes it quite convenient to control and check on videos on your smartphone end via the VIOFO App, including setup menu, live view from the front and behind, playback of recorded videos, and downloading/sharing of video files.

What is worth mentioning, A229 Duo is built with upgraded 5GHz Wi-Fi connection technology providing transfer speeds up to 8MB/s, 4 times faster than traditional 2.4GHz Wi-Fi. As well as this, it is compatible with more new phone models.


Intelligent Voice Notification

Configured with multiple language voice notifications, the A229 Duo car dash camera helps you confirm setting changes such as audio recording on/off and reminds you of events such as video protection and memory card errors. No more worries about missing important videos as the A229 Duo will inform you in time if anything prevents recording.


Built-in GPS Mount

The GPS mount can track the route data throughout your trip as well as speed and time data in the video file, allowing compatible viewers to display it on playback. It will also keep the camera clock synchronized with GPS time so that the video files are correctly time stamped.


3 Advanced Parking Modes

The A229 Duo dashcam has three advanced parking modes: Auto Event Detection, Timelapse, and Low Bitrate Recording, which help drivers to capture full evidence during parking.


advanced parking modes


1. Auto Event Detection:

Automatically record for 45s when detecting moving objects or impacts during parking. Optimized with buffered function, its 45s-video recording starts 15 seconds before and ends 30 seconds after the defected event.

2. Time Lapse Recording:

Record a video at low frames at 1/2/3/5/10 fps and compress it into a log file.

3. Low Bitrate Recording:

Record videos continuously at a low bitrate 4Mb/s with audio recorded.


Tips: To use the parking modes of the A229 Duo, we recommend using the VIOFO HK4 hardwire kit cable, whose ACC function will automatically switch the A229 Duo dashcam into parking mode or normal recording.
