The system is compatible with recommended models like Western Digital My Passport SSD and Samsung T9 Portable SSD, ensuring reliable performance for extensive data storage needs.

Smart Voice Control & Notification: Hands-Free Operation and Alerts
The VIOFO A329SW dash cam offers smart voice control, allowing drivers to stay focused on the road while performing essential functions. Simple spoken commands in multiple languages can start recording, take photos, and turn Wi-Fi on or off. The camera also provides clear voice notifications for settings changes or memory card errors, enhancing safety and usability during driving.

Accurate Quad-Mode GPS Tracking: Detailed Location and Speed Data
The built-in GPS module in the A329SW dash cam supports four global navigation satellite systems: GPS, BeiDou, Galileo, and GLONASS. This comprehensive tracking provides detailed location, speed, and time data of the vehicle when playing back videos on the VIOFO App or PC player. This feature adds an extra layer of safety and verifiable evidence for accident reconstruction or route analysis.

Multiplex Video: Customizable Multi-Angle Video Recording
The VIOFO A329SW dash cam supports Multiplex Video, allowing it to record videos with any combination of camera views. Users have full control over how their videos are presented, whether a single perspective or a multi-angle overview is needed. This feature eliminates the need for post-capture editing, providing instant sharing capabilities for comprehensive incident documentation or travel vlogging.

Vehicle Battery Protection: Smart Parking Mode Power Management
The A329SW dash cam offers two robust methods to prevent battery drain during parking mode. It can automatically stop parking recording based on a preset duration or voltage cutoff, safeguarding your vehicle's power supply. Additionally, if an optional hardwire kit is used, it will automatically cut off power supply when it detects a low voltage, ensuring the car battery remains charged for vehicle startup.
Smart Geo-Fencing Control: Automated Power Saving in Safe Zones
With Smart Geo-Fencing, users can select a specific 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 prevents unnecessary battery drain while saving power in chosen safe zones, such as a home garage. Geo-Fencing provides intelligent, automated power management for parked vehicles.

Low Power Impact Detection Parking Mode: Long-Lasting Incident Protection
This parking mode features very low power consumption, actively preventing battery drain while providing continuous protection. When the vehicle is turned off, the camera switches to a standby state. Upon detecting an impact, it wakes up in approximately 2 seconds and begins recording for one minute, capturing evidence of theft, hit-and-runs, and other incidents to safeguard your car with vital footage.

Hybrid Parking Recording: Comprehensive Event Coverage
The A329SW offers a Hybrid Parking Recording mode, combining various recording strategies for comprehensive incident capture. This mode begins with either time-lapse 1fps, low bitrate, or event detection, and intelligently switches to impact detection based on a preset cut-off time or voltage. This combination ensures that all types of parking incidents are covered efficiently, maximizing evidence capture while managing storage.
Time Lapse Recording Parking Mode: Efficient Storage for Long Durations
The Time Lapse Recording parking mode records video without audio at optional frame rates of 1, 2, 3, 5, or 10 frames per second. This method significantly saves storage space and power consumption, making it ideal for extended parking surveillance periods. Combined with an all-new Super Night Vision feature, scenes captured in time-lapse are clearer than ever in low light, providing efficient and effective long-term monitoring.
Super Night Vision (SNV): Enhanced Low Light Clarity
The VIOFO A329SW dash cam features advanced Super Night Vision (SNV), ensuring scenes captured during both driving and time-lapse recording are clearer than ever in low light. This technology dramatically improves image clarity and detail in dark environments. Drivers receive enhanced visibility and more reliable evidence in nighttime or dimly lit parking scenarios, bolstering overall security.

Auto Event Detection Parking Mode: Buffered Incident Capture
Supported by a buffered function, the Auto Event Detection parking mode automatically starts recording once moving objects are detected. The camera saves footage from 15 seconds before and 30 seconds after the event, ensuring the entire incident is captured. This provides crucial context for any impact or motion-triggered event, offering comprehensive evidence for vehicle protection.
Circular Polarizing Lens (CPL) Filter: Reduces Glare and Enhances Clarity
A Circular Polarizing Lens (CPL) filter can be used with the front camera to effectively reduce reflections and glare off glass and road surfaces. This optical accessory significantly improves image clarity and contrast by minimizing bright spots caused by sunlight or headlights. The included CPL filter ensures clearer, more vibrant video recordings, especially during sunny conditions or when reflections are prominent.

Bluetooth Remote Control (Optional): Convenient On-Demand Protection
An optional Bluetooth remote control provides convenient, safe operation while driving, with a control distance of 5 meters. Positioned in an easily accessible location, pressing the middle button instantly protects the current video clip and image from being overwritten. The two side buttons can be customized to set different functions, offering personalized control over key dash cam features without diverting attention from the road.
