VIOFO A329S 3CH - Complete Multi-Angle Coverage
The VIOFO A329S 3CH is an advanced 3-channel dash cam providing simultaneous front, cabin, and rear coverage for your vehicle. It combines a fast Quad-Core processor with Sony STARVIS 2 sensors across all three cameras. You get crisp 4K front video alongside detailed 2K video for the cabin and rear.

Triple Camera System Powered by Sony STARVIS 2
Unlike basic dash cams, the A329S 3CH uses premium hardware for every lens. This gives you sharp video, low digital noise, and clear contrast day and night.
Front Camera: 4K Sony STARVIS 2 IMX678 (Up to 60FPS)
The front lens captures a wide 140° field of view in sharp 4K (3840×2160P) using the Sony STARVIS 2 IMX678 sensor. You can also switch to 1-channel or 2-channel mode to record at a smooth 60 frames per second (60FPS). This eliminates motion blur so you can pause video and read fast license plates easily.

Cabin Camera: 2K Sony STARVIS 2 IMX675 with 210° Fisheye
Protect your car inside and out. The massive 210° fisheye lens captures the whole cabin and side door windows in one view. Four infrared (IR) LEDs provide complete visibility in dark parking conditions.

Rear Camera: 2K Sony STARVIS 2 IMX675 with HDR
The rear camera provides wide 160° coverage in clear 2K HDR. Rear recording is essential to document tailgaters and rear-end collisions clearly.

Smart Video Features & Balanced Lighting
3-Channel HDR Processing
Harsh midday sun and glare are no longer an issue. High Dynamic Range (HDR) balances bright highlights and deep shadows in real time across all three cameras.
Super Night Vision (SNV)
VIOFO's Super Night Vision keeps crucial road details and license plates sharp on pitch-black highways and unlit neighborhood streets.
Dynamic Interior Viewing
Use the mobile app to easily switch your cabin video between a wide fisheye perspective and a natural flat view to review events clearly.
60FPS Smooth Capture
Switch to 1- or 2-channel recording mode for smooth 60 frames per second capture. This freezes high-speed action and license plates with zero blur.
Smart Parking Security & Battery Safety 24/7
The A329S guards your vehicle day and night. Connect an optional hardwire kit or OBD cable to unlock professional 24/7 surveillance features that protect your car and battery:
Smart Geo-Fencing
Automatically adjusts parking modes based on your GPS coordinates. Get full security in public lots while conserving power when parked at home.
Low Power Impact Mode (Requires HK6)
Operates on ultra-low standby power. If an impact occurs, the camera wakes up within 2 seconds to record and lock a protected video clip.
Buffered & Time-Lapse Modes
Auto Event Detection saves 15 seconds before and 30 seconds after motion. You can also use Time-Lapse mode for space-saving continuous recording.
Vehicle Battery Protection
Stops your car battery from draining flat. The power cable cuts off power to the dash cam automatically if battery voltage falls below a safe level.
Next-Gen Connectivity, 4TB Storage & Coaxial Cabling
Experience rapid file transfer speeds and massive storage capacities built for daily and commercial driving:
External 4TB SSD & Multiplex Recording
Connect an external USB-C SSD up to 4TB. Use Multiplex recording to combine all three camera angles into a single file automatically, with Auto-Backup to prevent card wear.
Wi-Fi 6 & USB 3.0 Direct
Transfer videos wirelessly to your smartphone at up to 30MB/s with Wi-Fi 6, or use a direct USB 3.0 cable connection for high-speed 55MB/s data transfers.
Ultra-Slim Coaxial Cabling
Ultra-thin coaxial cables route invisibly behind weatherstripping and car trim without causing electromagnetic interference to your radio or GPS systems.
Quad-Mode GPS Logging
Connects to four satellite networks simultaneously (GPS, GLONASS, Galileo, BeiDou). It embeds precise speed, time, and route coordinates into your videos.
Smart Voice Control
Operate the camera safely while driving. Simple spoken English commands let you lock emergency clips, take photos, or turn on Wi-Fi without taking your hands off the steering wheel.
2.4" Display & Supercapacitor
Easily check live camera angles and settings on the bright 2.4-inch display. Powered by an industrial supercapacitor rated to withstand Saudi summer heat up to 65°C safely.
What's In the Box
Everything you need for a professional setup is included: a front CPL-200 Polarizing Filter to reduce windshield glare, ultra-slim coaxial cables for hidden routing, and a fast 45W Dual Type-C car charger to power the camera and quickly charge your phone.

Frequently Asked Questions: VIOFO A329S 3CH
Q: What are the recording resolutions when all 3 cameras are running?
A: When all three cameras are connected, the system records simultaneously in 4K (2160P @ 30fps) on the Front, 2K (1440P @ 30fps) in the Cabin, and 2K (1440P @ 30fps) on the Rear.
Q: Does the cabin camera record clearly at night without interior lights?
A: Yes. The cabin lens features 4 invisible 940nm infrared (IR) LEDs and an auto light sensor. It captures sharp monochrome video even in complete darkness.
Q: Why is the 210° fisheye cabin lens important?
A: It provides near-complete 360° security. The ultra-wide field of view covers the entire passenger cabin and looks through both side door windows to record side impacts and driver-window interactions.
Q: Can I use an external SSD up to 4TB?
A: Yes, the camera natively supports USB-C SSDs up to 4TB. Due to intense Saudi summer heat, we recommend using high-quality SSD enclosures with good heat dissipation, or relying on original VIOFO industrial microSD cards as your primary drive.
Q: Do I need the HK6 Hardwire Kit or the OBD cable for parking mode?
A: Yes, you need one of them to power the camera while the vehicle engine is turned off. The HK6 kit connects to your fuse box for a concealed pro installation, while the OBD cable offers a fast plug-and-play DIY setup. Both protect your car battery from draining flat.
Q: Is professional installation required?
A: Basic setup using the 12V cigarette lighter charger can be completed on your own in minutes. To enable 24/7 parking surveillance using the HK6 kit, professional installation is recommended to safely route fuse connections. For an easy DIY parking mode setup, you can use the OBD cable instead.
