VIOFO A129 Pro vs. Vantrue X4S

The highest resolution dash cam on the market is currently 4K, with image quality nearly equivalent to high-end, crystal TVs and camera systems. These dashcams are assured to capture the most detailed information required for evidence, including road signs and license plates.

The VIOFO A129 Pro, released in 2019, and the newer Vantrue X4S are two of the most discussed 4K dashcams on Reddit, Dashcamtalks, and other forums where users share their experiences. Let's see which of the 4Ks is the best fit for you.

One of VIOFO's flagship dash cams is the VIOFO A129 Pro Duo. It is a 2-channel system with all of the features of its predecessors, the A129 and A119, but with a front-facing camera that records in true 4K UHD.

The VIOFO A129 Pro Duo, which is equipped with an 8MP Sony Exmor R STARVIS image sensor, captures clear, vibrant colors with adequate detail in 4K UHD in the front and Full HD in the rear camera in all lighting conditions.

If you only use the front camera, your resolution options are 4K at 30FPS or 2K at 60FPS. You can also scale it down to 1080 Full HD at 60 or 120 frames per second. However, if you use both the front and rear cameras simultaneously, video recording in the front camera is limited to 30 frames per second. The front camera captures at 130° and the rear camera at 140°, ensuring that nothing is missed, day or night.

The VIOFO A129 Pro Duo protects your car by recording videos when it detects movement or impact, even when you are not present. The buffered recording includes the few seconds before and after the triggered event, giving you the full picture. To enable this feature, you will need a 3-wire Hardwiring cable or an external battery pack (such as the BlackboxMyCar PowerCell 8).

This VIOFO A129 Pro Duo includes an external GPS module. You can use GPS to record your speed and route data in your video footage files. The GPS will also sync the A129 Pro's clock with the GPS time, allowing your video files to be properly time-stamped.

Unlike other dashcams, this allows you to watch videos without having to remove the memory card from the device. The 2" screen, or the built-in dual-band WiFi dash cam, and the additional 5GHz frequency on the VIOFO A129 Pro Duo allows you to connect with the VIOFO App to control dash cam settings and access footage clips on the fly.

In hot weather, 4K dash cams are more prone to overheating, especially when used in parking mode inside a roasting car in the middle of summer. As previously stated, the VIOFO A129 Pro Duo includes an integrated cooling system. The A129 Pro has an operating temperature range of -10 to 65 degrees Celsius, making it suitable for hot southern summer days.

With three parking detection modes to choose from, the X4S protects your car for up to 24 hours daily. Activating its time-lapse function, it will automatically take photos at predetermined intervals and combine them into a video clip, saving you a lot of space on your memory card. Furthermore, when the built-in gravity sensor detects a sudden collision while parked or driving, this Vantrue automatically records and locks the file to prevent the most crucial video from being overwritten.

Vantrue also offers an optional GPS mount that lets you view the dashcam's live speed while driving. It also tracks the exact driving route, speed, and location on Google Maps using the Vantrue GPS player or WiFi APP.

If you wish to playback footage, the dash cam's 3" IPS screen makes it simple to access recorded videos and photos and change settings. The 2.4GHz and 5GHz WiFi options are also designed to avoid wireless interruption, allowing you to download and transfer data more steadily and quickly.

The X4S can also withstand extreme temperatures ranging from -4° to 158°F. It can also support external memory capacities of up to 512GB, allowing you to record and capture hours of video in a loop.
