VIOFO A229 PLUS 2 Channel

Q: Should I buy the A229 Plus or the A229 Pro?
A: The A229 Plus records 2K+2K (both cameras at 2560×1440). The A229 Pro records 4K+2K (front at 3840×2160). Both use Sony STARVIS 2 sensors with identical HDR quality on the rear camera. The Pro includes a CPL filter; the Plus does not. If 2K resolution meets your needs, the Plus delivers outstanding value. If you want the highest possible front resolution or the Wirecutter-recommended camera, choose the Pro.

Q: Is 2K resolution enough for a dash cam?
A: For most drivers, yes. 2K (2560×1440) with Sony STARVIS 2 captures sharp detail including license plates at normal following distances. The STARVIS 2 sensor’s superior dynamic range often matters more than raw resolution — a 2K STARVIS 2 camera frequently outperforms 4K cameras with older sensors in real-world conditions like nighttime driving, rain, and mixed lighting.

Q: Does the A229 Plus 2CH support HDR on both cameras?
A: Yes. Both the front and rear cameras process HDR simultaneously. This is a significant advantage over many competitors that apply HDR only to the front camera, leaving the rear channel washed out by headlights or underexposed in shadows.

Q: Can I use the A229 Plus with the RTC300 Telephoto camera?
A: Yes. The RTC320 telephoto camera is compatible with both the A229 Plus and A229 Pro front units. It connects to the Type-C rear port, so using the telephoto replaces the standard rear camera connection. This gives you 2K wide-angle front + 2K telephoto zoom.

Q: Is a CPL filter included with the A229 Plus?
A: No. Unlike the A229 Pro, the A229 Plus does not include a CPL filter in the box. It is available as an optional accessory. A CPL filter reduces dashboard reflections and windshield glare, recommended for optimal image quality, especially if you have a light-colored dashboard.

Q: Can I upgrade the A229 Plus to a 3 Channel System?
A: Yes. Add the optional interior camera module for 3-channel coverage: 2K front + 2K rear + 1080P interior with IR night vision. The interior camera connects to the front unit and is detected automatically. This makes the A229 Plus a budget-friendly option for rideshare drivers who need cabin documentation.

Q: Does the A229 Plus support the same parking mode as the Pro?
A: Yes. The A229 Plus supports all three parking modes: buffered Auto Event Detection (15 seconds pre-event + 30 seconds post-event), Time-Lapse, and Low Bit Rate recording. All modes require the HK4 hardwire kit (sold separately). Impact-triggered videos are automatically locked.

Q: What is the main advantage of the A229 Plus over Budget dash cams?
A: The Sony STARVIS 2 sensor. Many budget dash cams use older or smaller sensors that struggle in low light, produce noisy nighttime footage, and blow out highlights from headlights. The A229 Plus’s IMX675 delivers professional-grade dynamic range and low-light performance at a consumer price point — the same sensor technology used in the rear camera of the flagship A229 Pro.
