VIOFO A229 Ultra 2CH | Dual 4K UHD 30FPS Dash Cam with Matched 8MP Sony STARVIS 2 IMX678 Front & Rear, Dual HDR, Quad GPS & 5GHz Wi-Fi
VIOFO A229 Ultra 2CH — Dual 4K UHD 30FPS, Matched 8MP Sony STARVIS 2 IMX678 on Both Front & Rear
The VIOFO A229 Ultra 2CH is the only two-channel dash cam in the A229 lineup to use the same flagship 8MP Sony STARVIS 2 IMX678 sensor on both the front and rear cameras. Both channels record in 4K UHD (3840×2160) @ 30FPS with an F1.8 aperture and 140° field of view — delivering identical resolution, dynamic range, and low-light performance from both road-facing directions simultaneously. Dual-channel HDR, quad-mode GPS, dual-band 5GHz Wi-Fi, USB-C direct transfer at up to 20MB/s, voice controls, H.264/H.265 recording, and a CPL filter included.
Matched 8MP Sony STARVIS 2 IMX678 — True 4K UHD on Both Channels
The headline differentiator of the A229 Ultra 2CH vs the A229 Pro 2CH: both cameras use the identical flagship sensor.
- Front — 8MP Sony STARVIS 2 IMX678 (1/1.8"): 4K UHD (3840×2160) @ 30FPS | F1.8 aperture | 140° FOV
- Rear — 8MP Sony STARVIS 2 IMX678 (1/1.8"): 4K UHD (3840×2160) @ 30FPS | F1.8 aperture | 140° FOV
The A229 Pro 2CH uses the 5MP IMX675 (1/2.8") for the rear, delivering 2K QHD. The A229 Ultra 2CH upgrades the rear to the same 8MP IMX678 as the front — meaning rear footage has the same license plate clarity, the same low-light performance, and the same dynamic range as the front camera. For drivers who need maximum rear-facing evidence quality — tailgaters, rear-end collisions, parking incidents — this is the meaningful upgrade.
Dual-Channel HDR + Sony STARVIS 2 Night Vision — Both Cameras
HDR is active on both channels simultaneously, automatically balancing exposure across each camera independently. The IMX678’s large 1/1.8" sensor size and F1.8 aperture capture significantly more light than smaller sensors, delivering exceptional low-light performance on both front and rear. License plates, road signs, and incident details remain legible in headlight glare, tunnel transitions, and near-complete darkness — from both directions.
Quad-Mode GPS + Dual-Band 5GHz Wi-Fi + USB-C Direct Transfer
Built-in quad-mode GPS (GPS + GLONASS + Galileo + BeiDou) provides fast satellite lock and accurate speed, location, and timestamp data embedded in every video file — essential for insurance claims and incident documentation. Dual-band 5GHz Wi-Fi enables wireless video preview and download via the VIOFO app (iOS & Android) without removing the SD card. For maximum speed, the USB-C direct connection transfers files at up to 20MB/s on compatible smartphones — practical for quickly pulling dual 4K clips after an incident. The USB-C connection also enables effortless firmware updates.
Voice Controls + Parking Mode
Built-in voice controls let you start/stop recording, capture photos, lock footage, and toggle audio hands-free while driving. When hardwired, parking mode uses motion detection and G-sensor impact triggers to automatically initiate recording, with time-lapse mode compressing extended parking sessions and low-voltage protection safeguarding your battery.
H.264 / H.265 + 512GB Max SD + CPL Filter Included
Supports both H.264 and H.265 video encoding — H.265 delivers significantly smaller file sizes at equivalent quality, extending recording time on the same SD card for dual 4K continuous recording. Supports microSD cards up to 512GB. The CPL filter for the front camera is included in the box, reducing windshield glare and dashboard reflections for cleaner daytime footage.
