Now, let’s talk about how these dash cams capture footage. We know that both are equipped with Sony STARVIS 2 IMX678, have HDR, have 2MP Sony STARVIS sensors for their secondary dash cams, and record using a three-channel configuration. The A139 Pro, however, also has Wide Dynamic Range features. Check out how HDR and WDR work in dash cams here. Additionally, the A139 Pro also boasts Super Night Vision 2.0, making night recordings look more vibrant and balanced.
The field of view of the Vantrue N4 Pro measures 155° for the front, a bit wider than the A139 Pro’s 140°. However, when it comes to the interior and rear cameras, the A139 Pro captures at 170°, wider than the N4 Pro’s 165° and 160° respectively so you get more lanes from behind, and wider coverage for your passengers inside the car. We highly recommend this for Uber, Lyft, and other ride-sharing services. Additionally, the A139 Pro has 6 IR LEDs compared to the N4 Pro’s 4 LEDs, so with the VIOFO, you get sharper details even in complete darkness.
It’s also worth noting that the A139 Pro supports higher frame rates in various modes, such as 60fps in 2K mode, enabling smoother video playback – which is non-existent in the N4 Pro.
For maximum sharpness and clarity, the free CPL filter that comes with the A139 Pro also reduces glare and reflections. The N4 Pro is also compatible with a CPL filter, although you must buy it separately. If you wish to add more protection, you can also get the BlackboxMyCar Aqua Shield which works to prevent your dash cam from being ruined by raindrops, dust, and other environmental elements.
