VIOFO A329S 3CH: 4K Front, 2K Rear and a 210° Infrared Fisheye Cabin Camera
23 May 2025
Whether you carry passengers for a living, drive the family around or simply want a record of everything that happens in and around your car, a cabin camera is worth having. And the one in the VIOFO A329S 3CH sees a lot more than most.
After the great response to the A329, VIOFO heard one request again and again: can it support three channels? The A329S 3CH is the answer. It pairs a 4K front camera and a 2K rear camera with a 2K infrared fisheye cabin camera. Using a Sony STARVIS 2 IMX675 sensor, that cabin camera is VIOFO’s first interior camera with a 210° field of view and 2K resolution, giving a clearer, wider view inside and out. Flexible bundles mean you can pick the set-up that suits you, whether you drive solo, with family or run a fleet.
What makes the A329S 3CH stand out
Powered by a quad-core ARM Cortex-A53 chipset and Sony STARVIS 2 sensors, the A329S records true 4K and 2K footage, capturing number plates and fine details clearly, day and night.
4K front, 2K rear and 2K fisheye cabin cameras
The 4K front camera records the road ahead in sharp detail, the 2K rear camera keeps watch behind without distracting you, and the upgraded cabin camera delivers clear interior footage in 2K.
2K infrared fisheye cabin camera with a 210° view
With STARVIS 2 technology and enhanced HDR, the fisheye cabin camera records in 2K with impressive detail and clarity.
As VIOFO’s first interior camera with an ultra-wide 210° field of view, it gives a wider view than ever and captures both inside and outside the vehicle. Four infrared LEDs help it keep detail in low light, when you need it most.
See more, inside and out
Here’s the big advantage of a fisheye cabin camera over a standard one:
Two recording modes
The cabin camera has two modes, Ultra-wide Angle and Fisheye, and helps reduce blind spots around your vehicle.
Ultra-wide Angle mode: captures inside and outside the car, so if someone breaks in you’ll have a clear shot of their face, and if your door gets clipped, that’s recorded too.
Fisheye mode: switch to an immersive fisheye view in the settings for a fun extra on family trips.
Three Sony STARVIS 2 sensors
The front camera uses a Sony STARVIS 2 IMX678 1/1.8-inch 8MP sensor for more detail, less noise in low light and less motion blur. The rear and cabin cameras use Sony STARVIS 2 IMX675 1/2.8-inch 5MP sensors, with 2.5 times the dynamic range of STARVIS sensors of the same size.
Together, they give you clear, well-exposed and stable footage in all lighting, which is what matters for evidence and peace of mind.
HDR on all three channels
STARVIS 2 and HDR balance bright and dark areas to reveal fine detail and capture number plates accurately, even at speed, on every channel.
New parking modes
Vehicle battery protection: the camera can stop recording automatically at a preset time or voltage cut-off, or rely on the hardwire kit, which cuts power when it detects low voltage.
Low Power Impact Detection: when you switch off, the camera goes into a low-power standby. If it detects an impact, it wakes within two seconds and records for one minute.
Hybrid Parking Recording: combine time-lapse 1fps, low bitrate or event detection with impact detection. Recording starts in the first mode, then switches to impact detection based on the cut-off time or voltage. (Voltage cut-off is only available with the HK6 hardwire kit.)
More useful features
Multiplex video with no editing needed
Export a single view or a multi-angle video just the way you want it, without editing.
Two ultra-slim coaxial cables
Slim coaxial cables and miniature connectors make for a neat, hidden install. Coaxial cable resists electromagnetic and radio interference, so it won’t upset other in-car electronics, and supports high bandwidth whatever the length.
Supports SSDs up to 4TB
External SSD support extends recording time to up to three weeks (SSD not included). Footage can be backed up from the SD card to the SSD, and portable SSDs are supported too.
Plus the features you’d expect
- Wi-Fi 6: download a one-minute 4K clip in about 10 seconds for quick previewing and sharing.
- Voice control and notifications: control recording, photos and Wi-Fi by voice, with alerts for setting changes or card errors.
- Circular polarising lens (CPL): cuts reflections and boosts contrast and colour. Supported front and rear, with the front CPL included and the rear sold separately.
- Accurate GPS tracking
- Normal parking mode
- Loop recording and automatic emergency lock
- Dual Type-C car charger
- Bluetooth remote control (optional)
- USB 3.0 port
Final thoughts
With a 2K fisheye cabin camera and an ultra-wide 210° view, the A329S 3CH raises the bar for all-round vehicle coverage. Add 4K front and 2K rear recording on Sony STARVIS 2 sensors, HDR, Wi-Fi 6 and SSD support, and it captures your whole journey, inside and out, from the scenery to the back-seat singalongs.
