Summary

A front-and-rear dash cam that records 4K up front and 2K in back on Sony STARVIS 2 sensors, with HDR, GPS, voice control and a buffered parking mode. Budget for a high-endurance memory card and the hardwire kit, because neither comes in the box.

Strengths

  • 4K front and 2K rear footage on Sony STARVIS 2 sensors, with HDR on both channels.
  • Wirecutter names it the best overall dash cam, and CNET calls it the best multi-channel pick.
  • Buffered parking mode keeps 15s before and 30s after a detected event.
  • 5GHz Wi-Fi, quad-mode GPS, voice control and an included front CPL filter.
  • Supercapacitor power instead of a lithium battery holds up better in heat.
  • Owner sentiment runs about 91% positive.

Weaknesses

  • The VIOFO phone app is widely called unintuitive, and reviewers found the Wi-Fi fussy about connecting.
  • 4K recording writes about 1.1–1.2GB per 5 minutes, so a 512GB high-endurance card is effectively required and is not included.
  • The HK4 hardwire kit needed for parking mode is sold separately and may not include fuse taps.
  • The 4K front unit runs hot, with reports of thermal shutdown in hot conditions.
  • At least one owner reports the front camera not recording during an accident.
  • Parking mode draws more current than competing models, and the app’s settings are limited.

Video and sensors

The A229 Pro pairs a 4K front camera on the Sony STARVIS 2 IMX678 sensor with a 2K rear camera on the IMX675, both with HDR. The front lens is rated at 140° diagonal, though DashCamTalk measured closer to 160°; the rear is listed at 160°. Independent testers rate the video highly: Wirecutter names it the best overall dash cam, Consumer Reports includes it in its dash-cam test program, and CNET calls it the best multi-channel dash cam. There is no 4K60 mode on the Pro; the A329S is the model that offers it.

Storage and running costs

4K footage writes roughly 1.1–1.2GB per 5 minutes, so a 512GB high-endurance card is the practical minimum; VIOFO and owners recommend its own industrial cards or SanDisk Max Endurance, and warn against SanDisk High Endurance. The card is not included, and the hardwire kit for parking mode is a separate buy. The only other extras are the optional CPL-300 rear filter at $12.99 and the optional BTR200 Bluetooth remote. Format the card before first use and periodically, using exFAT or FAT32.

App, Wi-Fi and firmware

The recurring complaint is the VIOFO app: owners call it unintuitive, and TheDrive found the Wi-Fi finicky about connecting. Firmware has also changed features after launch, and one owner reported the auto-HDR time setting disappearing after an update. Recording reliability is the top complaint in owner analysis, and one thread documents an A229 Pro that did not record the front camera during a crash, which VIOFO attributed to an early production batch.

Parking mode, heat and power

The buffered parking mode saves 15s before and 30s after a detected event and can run from the HK4 hardwire kit, which is sold separately. An installer’s assessment is that parking mode draws more current than competing cameras, so long parking sessions need the low-voltage cutoff. The 4K front unit runs hotter than the 2K A229 Plus, and owners report thermal shutdown in hot conditions. The supercapacitor in place of a lithium battery is the durability argument VIOFO leans on here.

What it costs

VIOFO’s own store lists the 2CH at $349.99, BlackboxMyCar lists it at $329.99 and RadarBusters at $359.99, while Consumer Reports shows it from $279.99 across retailers. PCMag listed it at $219 on sale from $329, and one July 2025 review recorded a third-party promo that dropped to $159.99. AutoRoamer cites it at about $260. The realistic band is roughly $220–330 depending on sales.

Is it worth it?

Below $260 the A229 Pro 2CH is easy to recommend: it carries the strongest independent endorsements among mid-range dual dash cams, with 4K front and 2K rear STARVIS 2 sensors, HDR on both channels and an included CPL filter. Between $261 and $300 it is still good value. From $301 to $350 it is fair, and above $350 it is weak unless you specifically want the VIOFO platform and its 3CH expandability. Remember the extras: a 512GB high-endurance card and the HK4 kit are not in the box, and registering the camera extends the 18-month warranty to 24 months.

Which model this is

This page covers the standard A229 Pro 2CH, the front-and-rear kit. Do not confuse it with the A229 Plus 2CH, the A229 Ultra 2CH or the front-and-telephoto A229 Pro Tele 2CH. The A229 Pro uses a different GPS mount and a USB-C rear cable, so mounts and cables from the older A229 Duo do not fit. The Amazon listing for the black version is ASIN B0CKYGLT5M.
