4K Front Recording: Exceptional Clarity with Sony STARVIS 2 IMX678 Sensor
The front camera of the VIOFO A329S records in true 4K resolution, utilizing the Sony STARVIS 2 IMX678 1/1.8'' 8MP image sensor. This sensor packs more pixels for greater clarity, reducing noise in low light and minimizing motion blur in fast-moving scenes. Drivers can reliably capture license plates and crucial road details day and night.

2K IR Cabin Recording: 210° Ultra-Wide View with Sony STARVIS 2 IMX675
The A329S features a fisheye cabin camera that records in enhanced 2K resolution, powered by the Sony STARVIS 2 IMX675 1/2.8'' 5MP sensor. This sensor offers 2.5 times wider dynamic range than standard STARVIS pixels, ensuring clear and sharp interior videos. Four infrared LED lights provide excellent low-light performance, while its 210° field of view captures the entire car cabin and side windows, reducing blind spots for rideshare or family car monitoring.

2-Channel HDR: Clear License Plates Even in Fast Motion
The VIOFO A329S utilizes 2-Channel HDR, combining Sony STARVIS 2 technology to balance extremely bright and dark areas in both front and cabin recordings. This feature reveals critical details and captures accurate license plates, even when vehicles are moving rapidly. It ensures vital evidence is preserved under varying light conditions.
4K 60FPS Front Recording: Ultra-Smooth Video for Fast-Moving Scenes
The A329S front camera offers ultra-smooth, crisp 4K visuals at an enhanced 60 frames per second (fps). This higher frame rate ensures that fast-moving scenes are captured with exceptional detail and fluid motion. For scenarios requiring advanced dynamic range, users can switch to 4K 30fps with HDR recording.
Wi-Fi 6 Connectivity: Faster 4K Streaming and Downloads
Equipped with advanced Wi-Fi 6 technology, the A329S boosts operation speeds by three times in the 5GHz band, reaching up to 30MB/s. This significantly enhances video previewing, downloading, and sharing directly to a smartphone. Users can download a one-minute 4K video in under 10 seconds, providing rapid access to footage during emergencies.
Upgraded USB 3.0 Port: Ultra-Fast Video Downloads to Smartphones
The dash cam supports seamless connectivity to smartphones via an upgraded USB 3.0 data cable, enabling ultra-fast downloads of photos and videos. Download speeds can reach up to 55MB/s on compatible devices like the iPhone 15 Pro Max. This direct connection also facilitates effortless firmware updates, ensuring the dash cam always operates with the latest features and optimal performance.

Massive 4TB SSD Storage Support: Over Three Weeks of Footage
The A329S features external SSD storage support, significantly extending recording duration up to an impressive 4TB. This allows for over three weeks of continuous footage (based on average 3 hours/day, 2CH-IR, normal bitrate with 4TB SSD), alleviating concerns about running out of storage on long trips. It also supports backing up footage from the SD card to the SSD, reducing SD card strain and safeguarding important data.

Smart Voice Control & Notification: Hands-Free Operation for Safety
Stay focused on driving with the A329S's smart voice control feature, allowing users to start recording, take photos, and turn Wi-Fi on or off using simple spoken commands. The camera also provides clear audible notifications for settings changes or memory card errors. This multi-language voice command system enhances driving safety by minimizing distractions.

Accurate Quad-GNSS Tracking: Detailed Location and Speed Data
The built-in GPS module supports four global navigation satellite systems: GPS, BeiDou, Galileo, and GLONASS. This advanced tracking provides detailed location, speed, and time data of the vehicle. When playing back videos on the VIOFO App or VIOFO PC player, users can view this data alongside a map, adding an extra layer of safety and context to recorded incidents.
Multiplex Video Recording: Customizable Multi-Angle Footage
The A329S allows for multiplex video recording, enabling users to combine various camera views into a single video file without post-editing. Whether a single perspective or a multi-angle overview is needed, the dash cam provides full control over video presentation. This feature simplifies sharing and reviewing footage with specific perspectives.

Vehicle Battery Protection: Automatic Low Voltage Cut-Off
The dash cam offers two reliable methods to prevent vehicle battery drain during parking mode operations. It can automatically stop parking recording based on either a preset duration or a user-defined voltage cutoff threshold. Additionally, when used with a hardwire kit, the kit will automatically cut off the power supply if it detects low battery voltage, safeguarding the vehicle's starting power.

Smart Geo-Fencing Control: Save Power in Designated Parking Zones
With Smart Geo-Fencing, users can select a specific geographic area where the dash cam will completely shut down instead of entering parking mode when the vehicle stops and powers off. This feature requires no extra steps and actively prevents unnecessary battery drain, especially when the vehicle is parked safely in a home garage or other trusted location.
Low Power Impact Detection Parking Mode: 2-Second Wake-Up on Impact
This parking mode features very low power consumption, effectively preventing battery drain during extended surveillance periods. When the vehicle is turned off, the camera enters a standby state. Upon detecting an impact, it will wake up in approximately 2 seconds and immediately begin recording for one minute, capturing crucial evidence of theft, hit-and-runs, or other incidents.

Hybrid Parking Recording: Combining Time-Lapse, Low Bitrate, and Event Detection
The A329S offers Hybrid Parking Recording, a versatile mode that combines different surveillance techniques for comprehensive protection. It can begin with time-lapse 1fps, low bitrate, or event detection, and intelligently switch to impact detection based on a specified cut-off time or voltage. This adaptable mode provides optimal coverage while managing storage efficiently (cut-off voltage requires HK6 hardwire kit).
Time Lapse Recording Parking Mode: Efficient Storage with Super Night Vision
Time Lapse Recording in parking mode captures video without audio at selectable frame rates of 1, 2, 3, 5, or 10 frames per second. This method efficiently saves storage space and power, ideal for long-term surveillance. Featuring an all-new super night vision (SNV) capability, scenes captured in time-lapse are clearer than ever, even in low-light conditions.

Low Bitrate Recording Parking Mode: Continuous Surveillance with Audio
Low Bitrate Recording provides continuous surveillance in parking mode, generating mini file sizes to save significant space on the microSD card. Unlike some other low-power modes, it also records audio, providing a more complete record of events. This mode is excellent for maximizing recording duration without sacrificing crucial details.

Auto Event Detection Parking Mode: Buffered Recording for Critical Incidents
Supported by a buffered function, Auto Event Detection in parking mode automatically starts recording once moving objects are detected. The camera then saves footage from 15 seconds before the event and 30 seconds after, ensuring the entire incident is captured. This provides crucial context for any detected motion or impact, acting as a reliable security measure.

Loop Recording & Auto Emergency Lock: Continuous and Protected Footage
The VIOFO A329S supports seamless loop recording, automatically overwriting the oldest video files with the newest ones to ensure continuous operation. With its built-in G-sensor, the dash cam automatically locks the current footage in case of a collision or crash, preventing it from being overwritten. This preserves critical accident scenes for investigation and evidence.

Circular Polarizing Lens (CPL) Compatibility: Reduce Glare and Reflections
The front camera of the A329S supports an optional Circular Polarizing Lens (CPL) filter. This accessory effectively reduces reflections and glare off glass surfaces, such as the windshield, and road surfaces. The CPL filter brings improved image clarity and contrast, ensuring footage is free from distracting light artifacts.
