The key upgrade is the rear camera. The A229 Pro records 4K front + 2K rear (IMX678 + IMX675). The A229 Ultra records 4K front + 4K rear (dual IMX678 sensors). Both share the same STARVIS 2 platform, HDR, 5GHz Wi-Fi, GPS, voice control, and CPL filter. Choose the Ultra if you want maximum rear resolution — especially useful for capturing license plates and fine details behind the vehicle.
Yes. Both the front and rear cameras record true 4K (3840×2160) at the same time with HDR active on both channels. This is not interpolated or upscaled — both channels use the Sony STARVIS 2 IMX678 sensor for native 4K capture.
Yes. Add the optional 1080P fisheye cabin camera with IR night vision to upgrade to a 3-channel system (4K front + 4K rear + 1080P interior). The cabin camera connects directly to the front unit and is detected automatically — no firmware changes needed.
Yes. With the HK4 hardwire kit (sold separately), the A229 Ultra supports three parking modes: buffered Auto Event Detection (saves footage before and after an impact), Time-Lapse recording, and Low Bit Rate continuous recording. Impact-triggered videos are automatically locked to prevent overwriting.
Dual 4K recording consumes more storage than 4K+2K. A 256GB microSD card provides approximately 8–12 hours of continuous dual 4K recording. For longer coverage, use a 512GB card (maximum supported). No card is included — purchase a high-endurance card designed for continuous recording.
Yes. A CPL (circular polarizing) filter is included in the box. The CPL filter attaches to the front camera lens to reduce windshield reflections and dashboard glare, improving video clarity — especially during daytime driving with a reflective dashboard.
