VIOFO A229 Ultra 2CH — Uncompromised Dual 4K UHD Protection
Step into the future of automotive security with the VIOFO A229 Ultra 2CH, an advanced 2-channel dash cam engineered to eliminate vehicle blind spots by capturing genuine 4K Ultra HD video from both the front and rear simultaneously. Whether navigating dense city traffic or cruising desert expressways, this flagship dual-channel system delivers an impenetrable shield of high-resolution video evidence. Review critical clips, configure camera settings, and manage files directly on the vibrant 2.4-inch high-definition screen without ever removing the memory card.

Symmetrical Dual 4K Sony STARVIS 2 Architecture
The A229 Ultra refuses to compromise on rear video fidelity. By pairing identical 8MP Sony STARVIS 2 IMX678 image sensors on both channels, it delivers razor-sharp visual evidence and unmatched dynamic range in all lighting conditions.
Front Camera: True 4K Sony STARVIS 2 IMX678 (1/1.8" Sensor)
The forward-facing lens captures an expansive 140° field of view in genuine 4K Ultra HD (3840×2160P @ 30FPS). Powered by the large 1/1.8" 8MP sensor, its enhanced light sensitivity freezes high-speed traffic action and distant license plates with breathtaking sharpness.
Rear Camera: True 4K Sony STARVIS 2 IMX678 (1/1.8" Sensor)
The rear camera matches the front unit with genuine 4K Ultra HD resolution (3840×2160P @ 30FPS). An identical 8MP Sony IMX678 sensor ensures you capture tailgating behavior, road rage incidents, and rear-end collisions with pristine, zoomable detail.
Smart Video Features & Balanced Lighting
Dual Sony STARVIS 2 IMX678
Large 1/1.8" 8MP sensors on both cameras deliver superior light absorption, suppressing digital noise and freezing fast license plates with razor-sharp clarity.
2-Channel Real-Time HDR
Real-time HDR processing balances extreme lighting differences across both channels, neutralizing headlight glare and revealing clear details on dark expressways.
24/7 Smart Parking Security & Battery Safety
The A229 Ultra guards your vehicle around the clock. Connect an optional HK4 hardwire kit, HK6 smart kit, or OBD cable to unlock continuous 24/7 parking surveillance with built-in low-voltage battery protection:
Buffered Auto Event Detection
Automatically records and locks video 15 seconds before and 30 seconds after any detected motion or impact, providing complete uninterrupted evidence.
Time-Lapse Recording (1 to 10 FPS)
Captures continuous footage at selectable low frame rates (1 to 10 fps) without audio, significantly conserving memory card space during long parking periods.
Low Bitrate Continuous Recording
Maintains uninterrupted, non-stop recording at an optimized smaller file size with full cabin and road audio enabled for complete situational context.
Low-Voltage Vehicle Battery Cutoff
Prevents vehicle battery drain. The hardwire connection continuously monitors voltage levels and automatically disconnects the dash cam if levels drop below a safe threshold.
Fast 5GHz Connectivity, Quad-GPS & Discreet Cabling
Enjoy rapid file transfers, pinpoint satellite route logging, and a clean hidden installation:
Upgraded 5GHz Wi-Fi Module
Connect seamlessly to the VIOFO mobile app. Preview dual 4K video streams in real time, configure system settings, and download footage wirelessly without buffering.
Direct USB-C Smartphone Downloads
Connect a USB-C cable directly to your phone for rapid 20MB/s data transfers. Extract critical accident clips and update firmware easily (requires phone with 5V 2A output).
Quad-Mode GPS Logging
Synchronizes simultaneously with GPS, BEIDOU, GALILEO, and GLONASS to embed precise driving speed, timestamp, and route coordinates into your 4K video files.
Smart Voice Control & Spoken Alerts
Keep your hands on the wheel. Execute spoken voice commands to lock clips, snap photos, or toggle Wi-Fi, while spoken audio alerts keep you informed of recording status.
Ultra-Slim Coaxial Cabling
Ultra-thin coaxial cables route invisibly behind headliners and rubber door seals without generating electromagnetic interference with your car radio or navigation.
Loop Recording & G-Sensor Lock
Seamless loop recording continuously overwrites older files so storage never fills up, while the integrated G-Sensor automatically locks collision footage from erasure.
What's In the Box
Everything you need for a professional dual-channel setup is inside: front 4K camera, rear 4K camera, a front CPL-200 Polarizing Filter to remove windshield glare, slim coaxial rear cabling, 12V car power cable, trim removal tool, and mounting pads.

Recommended Accessories & Upgrades

VIOFO HK4 ACC Hardwire Kit (Optional)
Connects directly to your fuse box for concealed wiring. Unlocks 24/7 parking surveillance and protects your vehicle battery. (Choose either this kit, the HK6, or the OBD cable — only one is required).
VIOFO HK6 Smart Hardwire Kit (Optional)
Upgraded fuse box kit with a smart chip. Displays your vehicle's real-time battery voltage directly on the recorded video screen. (Choose either this kit, the HK4, or the OBD cable).
VIOFO OBD Power Cable (Optional)
An easy plug-and-play alternative to fuse box wiring. Plugs directly into your car's OBD-II port for quick 24/7 parking power and battery protection. (Choose either this cable, HK4, or HK6).
VIOFO MicroSD Cards (Up to 512GB)
Recording dual 4K streams creates heavy continuous data writes. These industrial-grade high-endurance cards survive constant write cycles and extreme Saudi heat.
VIOFO Battery Packs (Optional)
Keep your car battery safe while parked. These heat-resistant external battery packs power the dual 4K system for hours without draining your vehicle's starter battery.
CPL-600 Rear Filter (Optional)
The front CPL-200 filter is included in the box. Adding this rear CPL-600 filter eliminates back window glare and reflections from trailing vehicle headlights in bright sun.
BTR200 Bluetooth Remote (Optional)
Mount this small wireless button on your steering wheel or dashboard. Press it once to lock and save emergency video clips with 1 click.

Frequently Asked Questions: VIOFO A229 Ultra 2CH
What are the video recording resolutions of the VIOFO A229 Ultra 2CH?
Both front and rear cameras record simultaneously in true 4K Ultra HD (3840×2160P @ 30fps). Each channel is powered by an independent 8MP Sony STARVIS 2 IMX678 sensor with real-time HDR processing to eliminate glare and capture razor-sharp evidence.
Why is symmetrical Dual 4K Sony STARVIS 2 IMX678 recording superior to standard dash cams?
Most dual-channel systems downgrade rear camera quality to 2K or 1080P using smaller sensors. The A229 Ultra utilizes identical 1/1.8" 8MP Sony STARVIS 2 IMX678 sensors on both channels, ensuring rear footage has the exact same light sensitivity, dynamic range, and zoomable license plate clarity as the front camera.
Is the CPL polarizing filter included in the box?
Yes. The front CPL-200 circular polarizing filter is included directly in the factory packaging to eliminate dashboard reflections and windshield glare. The rear CPL-600 filter is available separately as an optional upgrade.
Do I need the HK4, HK6 Hardwire Kit, or the OBD cable for parking mode?
Yes. One of these power options is required to supply continuous 12V power when your vehicle's engine is off. The HK4 hardwire kit and HK6 smart kit connect directly to your fuse box for concealed wiring (with the HK6 displaying live voltage on-screen), while the OBD power cable offers a fast plug-and-play alternative. All options feature automatic low-voltage cutoff to safeguard your car battery.
Can the VIOFO A229 Ultra 2CH withstand extreme Saudi summer heat?
Yes. The A229 Ultra 2CH utilizes an industrial-grade supercapacitor instead of standard lithium batteries. This ensures stable, heat-safe operation in cabin temperatures up to 65°C (149°F), preventing risks of battery swelling, leakage, or thermal shutdowns under direct desert sun.
What microSD card is required, and does the A229 Ultra support external SSDs?
The system supports microSD cards up to 512GB. Because recording two simultaneous 4K streams generates heavy data loads, an industrial-grade high-endurance card rated U3, A2, V30 (such as genuine VIOFO microSD cards) is strictly required to prevent write bottlenecks and file corruption. The A229 Ultra does not support external USB-C SSD storage; if 4TB SSD support is required, explore the VIOFO A329 series.
Is professional installation required, and can this system be upgraded to 3 channels later?
Basic setup using the included 12V car power adapter takes only minutes. For 24/7 parking mode and concealed wiring via the HK4 or HK6 kit, our professional installation service is strongly recommended. Additionally, you can easily upgrade to 3-channel coverage in the future by adding the optional RNF210 cabin camera.
