Advanced Features
Dual STARVIS 2 Sensors & HDR
The A229 Plus utilizes dual Sony STARVIS 2 IMX675 image sensors for both front and rear cameras, providing enhanced dynamic range and light sensitivity, especially in low-light conditions. Dual-Channel HDR technology ensures balanced exposure and captures more detail in both bright and dark areas of the footage.

This image provides a visual comparison between the original STARVIS and the new STARVIS 2 sensors, demonstrating how STARVIS 2 significantly reduces image noise and motion blur, resulting in clearer footage, particularly in challenging lighting conditions.

This image illustrates the effectiveness of Dual Channel HDR by comparing a scene with HDR enabled versus without, showing improved detail in both bright and shadowed areas. It also highlights the upgraded 2K HDR capability of the rear camera.
Ultra-Precise GPS
The integrated Quad-Mode GPS module supports GPS, BEIDOU, GALILEO, and GLONASS satellite positioning systems, providing accurate location, speed, and time data that can be viewed during video playback on the VIOFO app or computer.

This image illustrates the Ultra-Precise GPS functionality, showing the dash cam tracking a vehicle's location using multiple satellite systems (GPS, BEIDOU, GALILEO, GLONASS). It also details the 24/7 Parking Mode options: Auto Event Detection, Time Lapse, and Low Bitrate Recording.
24/7 Parking Mode
To utilize parking mode features, the optional VIOFO HK4 Hardwire Kit is required (sold separately). Parking modes include:
- Auto Event Detection: Records 15 seconds before and 30 seconds after a detected event (e.g., impact or motion).
- Time Lapse Recording: Records video at a low frame rate (1/2/3/5/10 fps) to save storage space while continuously monitoring.
- Low Bitrate Recording: Records continuously in a smaller file size with audio, optimizing storage.
Circular Polarizing Lens (CPL) - Optional
The CPL filter can be attached to the front lens to reduce reflections and glare from glass and road surfaces, improving image clarity and contrast, especially in bright conditions.

This image provides a detailed close-up of the VIOFO Circular Polarizing Lens (CPL) filter, highlighting its design and optical elements.

This image showcases two optional accessories: the Bluetooth Remote Control, demonstrating its functions (Take Photo, Video Lock), and the Circular Polarizing Lens (CPL), illustrating its effect on reducing glare by comparing views with and without the CPL filter.
Bluetooth Remote Control - Optional
The optional Bluetooth remote control allows you to quickly take photos or lock video clips with a single press, without needing to interact directly with the dash cam. The control distance is approximately 5 meters.
Maintenance
- MicroSD Card Formatting: Format the microSD card regularly (e.g., once a month) to prevent file corruption and ensure optimal performance.
- Cleaning: Use a soft, dry cloth to clean the camera lenses and screen. Avoid using harsh chemicals or abrasive materials.
