VIOFO A329T 3-Channel 4K Dash Cam with Telephoto Zoom
The VIOFO A329T 3-Channel 4K Dash Cam is an advanced vehicle recording system that captures multi-angle video with a 4K front, 2K telephoto, and 2K rear camera setup. Powered by a Quad Core ARM Cortex A53 chipset and Sony STARVIS 2 sensors, it delivers true-to-life video clarity for drivers who demand comprehensive surveillance and detail capture in all conditions.
Quad-Sensor 4K + 2K + 2K Recording: Unmatched Multi-Channel Clarity
The VIOFO A329T dash cam system features a 4K (3840x2160@30fps) front camera, a 2K (2560x1440@30fps) telephoto camera, and a 2K (2560x1440@30fps) rear camera. This three-channel configuration provides complete surveillance around your vehicle, ensuring critical details like license plates are clearly visible from multiple perspectives. It offers comprehensive recording coverage for daily commutes, rideshare driving, or fleet management.

3-Channel HDR Recording: Capture License Plates in All Lighting
The dash cam integrates High Dynamic Range (HDR) technology across all three channels. This feature, combined with Sony STARVIS 2 sensors, expertly balances extremely bright and dark areas within the frame. It allows the VIOFO A329T to capture accurate license plate details and critical information even when vehicles are moving fast or transitioning between light and shadow.

2K Telephoto Camera with 4x Optical Zoom: Detail Capture From a Distance
The VIOFO A329T includes a dedicated telephoto camera that records stunning 2K video. This camera features a 4x optical zoom, enabling it to capture detailed scenes from a greater distance than a standard wide-angle lens. It is ideal for identifying distant license plates, observing specific events, or capturing detailed landscape views during long-distance driving tours.
Wi-Fi 6 Connectivity: Faster 4K Streaming and Downloads
The A329T is equipped with advanced Wi-Fi 6 technology, boosting operation speeds by three times in the 5GHz band, up to 30MB/s. This significantly enhances video previewing, downloading, and sharing directly from the dash cam to your smartphone. A one-minute 4K video can be downloaded in under 10 seconds, providing crucial speed for emergency footage retrieval.
Upgraded USB 3.0 Port: Ultra-Fast Video Downloads to Phone
The dash cam features an upgraded USB 3.0 port, allowing seamless and ultra-fast direct connectivity to smartphones via a USB 3.0 data cable. 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 device remains up-to-date with the latest features and optimal performance.

Up to 4TB External SSD Support: Extensive Recording Storage
The VIOFO A329T supports external SSD storage, greatly extending recording days up to over three weeks of footage. This feature eliminates concerns about running out of storage during long drives or extended parking surveillance. Recommended SSD models include Western Digital 1TB My Passport SSD and various SanDisk and Samsung Portable SSDs up to 4TB.

Smart Voice Control & Notification: Hands-Free Operation
Drivers can maintain focus on the road with smart voice control functionality. The camera responds to simple spoken commands in multiple languages (English, Chinese, Russian, Japanese) to start recording, take photos, or toggle Wi-Fi. Additionally, it provides clear voice notifications for setting changes or memory card errors, enhancing operational convenience and safety.

Quad-Mode GPS Tracking: Accurate Location and Speed Data
A built-in GPS module supports four global navigation satellite systems: GPS, BeiDou, Galileo, and GLONASS. This advanced system provides detailed location, speed, and time data for your vehicle. This information is accessible when playing back videos on the VIOFO App or VIOFO PC player, offering an extra layer of safety and evidence for any recorded incidents.
Multiplex Video Recording: Customizable Multi-Angle Views
The A329T allows users to record videos with any combination of camera views. This flexibility means you can choose a single perspective or a multi-angle overview depending on your specific needs. It provides full control over how your videos are presented without requiring external editing, simplifying instant sharing.
Intelligent Parking Mode Protection: Low Power Impact Detection
This parking mode features very low power consumption, preventing significant battery drain while the vehicle is off. When an impact is detected, the camera wakes up in approximately 2 seconds and records for one minute. This buffered recording captures theft, hit-and-runs, and other incidents, providing vital evidence without constantly draining the vehicle's battery.

Smart Geo-Fencing Control: Automatic Power Saving in Parking Zones
Geo-Fencing allows users to define specific areas where the dash cam will automatically shut down completely instead of entering parking mode when the vehicle stops. This feature prevents unnecessary battery drain while parked safely in a home garage or other chosen secure locations. It requires no extra steps from the driver, offering automatic power efficiency.

Hybrid Parking Recording: Comprehensive Event Coverage
The hybrid parking mode combines multiple recording strategies to maximize event coverage. It can begin with time-lapse (1fps), low bitrate, or event detection, then switch to buffered impact detection based on a preset cut-off time or voltage. This comprehensive approach ensures that various types of parking incidents are captured effectively, with cut-off voltage only available with the HK6 hardwire kit.

Circular Polarizing Lens (CPL) Support: Reduced Glare and Reflections
The VIOFO A329T supports the use of a Circular Polarizing Lens (CPL) filter on all three channels. This CPL filter effectively reduces reflections and glare off glass and road surfaces. Implementing a CPL filter results in improved image clarity and contrast, enhancing the visibility of details in bright conditions.
