Viofo A329T 4K 3-Channel Dash Cam - Sony STARVIS 2, 4x Optical Zoom, Voice Control, GPS & WiFi 6

The Viofo A329T 3CH is a triple‑camera 4K dash cam built for drivers who demand clear, court‑ready evidence from every angle. Commuters, rideshare pros, and fleet managers get wide front coverage, detailed rear protection, and a dedicated 2K telephoto lens with 4× optical zoom for capturing distant license plates. Its strongest benefit is precise, HDR‑enhanced detail across all three channels using Sony STARVIS 2 sensors.

Three‑Channel Coverage with Plate‑Level Detail

The A329T combines a 4K 30fps front camera with HDR, a 2K HDR telephoto camera, and a 2K HDR rear camera. The front sensor is Sony’s STARVIS 2 IMX678 (8MP, 1/1.8"), chosen for clarity and reduced noise, while the telephoto and rear use STARVIS 2 IMX675 (5MP, 1/2.8"). HDR processing on every channel helps balance bright sun, deep shadows, and headlight glare so key details stay visible.

The dedicated telephoto camera provides a narrow 35° field of view and true 4× optical zoom, isolating plates and road markings that wide lenses compress. Pair that with the front camera’s wide road context and the rear camera’s comprehensive coverage, and you have a complete picture before, during, and after an incident. A front CPL filter is included to cut windshield reflections; optional CPLs are available for the rear and telephoto cameras.

Parking Protection and Smart Power Management

Five parking modes let you match protection to your scenario. Choose Hybrid Parking Recording to blend time‑lapse, low‑bitrate, or event detection with impact triggers; or select normal modes such as Time‑Lapse (1/2/3/5/10 fps), Low Bitrate continuous, or Auto Event Detection with buffered capture that saves from 15 seconds before to 30 seconds after motion is detected. Low Power Impact Detection keeps standby draw minimal, then wakes the camera in about two seconds and records for one minute when a bump occurs.

Vehicle battery safeguards are built in. You can set a recording duration or a voltage cutoff, and with the optional hardwire kit the camera will shut down to protect the battery when low voltage is detected. Cutoff voltage control requires the HK6 hardwire kit. Smart Geo‑Fencing lets you define areas—like your home garage—where the dash cam will fully power down instead of entering parking mode to reduce unnecessary draw. During driving, loop recording keeps capturing while the G‑sensor automatically locks clips from collisions.

Connectivity, Control, and Evidence Management

Built‑in Wi‑Fi 6 with 2.4 GHz and 5 GHz gives you faster previews, downloads, and sharing through the Viofo app. For even quicker transfers and firmware updates, connect your compatible phone directly via the upgraded USB 3.0 data pathway using a USB‑C cable. Voice Control helps you start recordings, take photos, or toggle Wi‑Fi hands‑free, while Voice Notifications confirm settings changes and alert you to memory card issues.

Multiplex Video recording lets you save single or multi‑angle views without editing, making it easy to present evidence. The integrated GPS logger records speed, route, and time for review in the Viofo app or PC player. A built‑in microphone and speaker capture audio and deliver clear prompts, and status LEDs show power, recording, GPS, mic, and Wi‑Fi at a glance. An optional Bluetooth remote (BTR200) places clip protection within easy reach so you can lock important footage without touching the camera.

Storage, Reliability, and Installation

The A329T supports high‑endurance microSD cards up to 512GB and can connect to an external SSD up to 4TB for extended three‑channel recording. When using an SSD, Viofo recommends a Type‑C SSD cable and hardwired power. The camera can also back up footage from the SD card to the SSD, giving you flexible redundancy for mission‑critical use.

Built for everyday reliability, the A329T uses a supercapacitor instead of a lithium battery and is rated for operation from −20°C to 65°C. Dual ultra‑slim coaxial cables with compact connectors simplify routing to the rear and telephoto cameras, resist interference, and support high‑bandwidth video transmission. Setup and review are straightforward on the 2.4‑inch high‑resolution display, and USB Type‑C connectivity keeps your wiring modern and tidy. A dual Type‑C car charger and mounting accessories are included. For vehicles without a clear rear window, a related configuration (A329TW 3CH) offers a weather‑resistant rear camera option.

Whether you’re documenting daily commutes, safeguarding a rideshare route, or outfitting a small fleet, the Viofo A329T 3CH delivers detail where it counts: wide 4K context up front, zoomed 2K plate capture at a distance, and dependable 2K coverage behind. With HDR across all channels, flexible parking protection, Wi‑Fi 6, GPS, and expansive storage options, it’s a practical upgrade that helps you preserve what happened and why—on the road and while parked.
