4K front recording at up to 60fps
The A329S 2CH combines 4K 60fps front recording with a separate 2K HDR rear camera, dual Sony STARVIS 2 sensors and the fastest connected/storage platform in the A329S range — including Wi-Fi 6, USB 3.0 transfer and external SSD support up to 4TB.
The A329S is built for drivers who want more than image quality alone. Its performance story continues after recording — through Wi-Fi 6, USB 3.0, SSD backup and a more advanced parking platform.
The front camera uses Sony STARVIS 2 IMX678 8MP hardware; the rear uses Sony STARVIS 2 IMX675 5MP. Both lenses are F1.8, with 140° front and 160° rear fields of view.
1/1.8-inch 8MP Sony STARVIS 2 sensor, F1.8 aperture and 140° field of view.
1/2.8-inch 5MP Sony STARVIS 2 sensor, F1.8 aperture, wide 160° coverage and a 360° rotatable mount.
HDR is supported on both channels for stronger control of highlights, shadows and reflective number plates.
Record the road ahead and what happens behind the vehicle at the same time.
The IMX678 front sensor provides the pixel count required for native 4K, while the IMX675 rear sensor delivers detailed 2K coverage with a wider 160° field of view. STARVIS 2 technology improves low-light sensitivity and dynamic range across both channels.
HDR combines exposures to balance high-contrast scenes such as headlights, tunnels, shaded roads and reflective number plates. The rear camera records 2K HDR, while the front switches to 4K 30fps when HDR is enabled.
The front camera can record native 4K at 60fps for smoother motion. Switch to 4K 30fps to enable front HDR. The rear remains 2K 30fps.
At 3840×2160 and 60fps, the front camera captures more individual moments each second. That makes playback smoother and gives moving vehicles, signs and roadside detail more temporal information.
Use 4K 60fps when fast-moving detail and smoother playback are the priority.
Use 4K 30fps with HDR when headlights, shadows and reflective surfaces create the harder recording challenge.
Wi-Fi 6 handles everyday app access, USB 3.0 provides a much faster direct phone connection on compatible hardware, and Multiplex Video can combine views into a single shareable file.
Wi-Fi 6 can reach up to 30MB/s on the 5GHz band in an interference-free environment. A one-minute 4K clip can transfer to a phone in under ten seconds under the stated test conditions.
Use the VIOFO App for live view, camera settings, playback and downloads over the A329S dual-band Wi-Fi connection.
Connect the camera directly to a compatible USB 3.0 phone using a USB 3.0 data cable. Transfer speed can reach up to 55MB/s on supported hardware; the same direct connection can also be used for firmware updates.
USB 3.0 cable is not included. USB 3.0 transfer requires a compatible USB 3.0 device.
Measured on compatible hardware including iPhone 15 Pro Max.
Move footage and perform firmware updates without taking the microSD card out.
Multiplex Video can present multiple camera perspectives inside one split-screen video. That removes the need to manually sync separate clips when you want an all-angle overview of an incident.
Use spoken commands to start recording, take a photo or switch Wi-Fi on and off. Voice notifications can also tell you when settings change or when the memory card needs attention.
The camera can respond to key spoken actions while you keep attention on the road.
Built-in positioning uses GPS, BeiDou, Galileo and GLONASS. Download footage first when you want to view its route map in the VIOFO App or VIOFO PC player.
The A329S can record to an external portable SSD and can also back up microSD footage to SSD, giving long-distance drivers a storage option far beyond a conventional card.
Connect a supported portable SSD up to 4TB. In the standard 4K 60fps test scenario at three hours of driving per day, storage scales from around five days at 512GB to around forty days at 4TB.
Tested portable SSD families include WD My Passport, SanDisk Extreme Portable and Samsung T9. SSD and connection cable are sold separately.
Use compatible external storage for extended tours and high-capacity continuous recording.
Back up microSD footage to SSD to reduce card strain and keep important clips on a larger drive.
A VIOFO Type-C SSD cable is recommended. SSD is sold separately.
For Low Power Impact Detection or Hybrid Parking Mode, keep a microSD card inserted even if an SSD is connected. Wake-up recordings from the low-power state are written to microSD.
A329S adds Hybrid Parking Recording and Low Power Impact Detection alongside the familiar Time-Lapse, Low Bitrate and buffered Auto Event Detection modes.
HK4 supports basic parking recording and cut-off time protection. HK6 adds the A329S-specific advanced functions including cut-off voltage, Hybrid Parking Mode and Bluetooth battery-voltage display.
Hybrid Parking combines two parking behaviours. Start in 1fps Time-Lapse, Low Bitrate or Auto Event Detection, then switch to Low Power Impact Detection when the chosen cut-off time or battery voltage is reached.
In this ultra-low-power state the camera waits for an impact. Once triggered it wakes in roughly two seconds and records for one minute, reducing power draw during long unattended periods.
Time-Lapse records without audio at 1 / 2 / 3 / 5 / 10fps and can use Super Night Vision in low light. Low Bitrate records continuously with audio using smaller files. Buffered Auto Event Detection can retain 15 seconds before and 30 seconds after a detected event.
Create trusted zones such as your home garage or workplace. When the vehicle enters one of those zones, A329S can shut down instead of entering normal parking recording, reducing unnecessary power use. Low Power Impact Detection can still be kept active inside the zone.
The HK6 adds a parking timer, low-voltage cut-off and Bluetooth voltage monitoring in the VIOFO App. That lets parking mode stop before the vehicle battery falls beyond the selected threshold.
These are major differences between A329S and older VIOFO platforms, so they deserve more than a line in the specifications.
Loop recording, the built-in G-sensor, large-card support and supercapacitor power make up the everyday recording foundation beneath the flagship features.
Set 1 / 2 / 3 / 5 / 10-minute loop files. When the adjustable G-sensor detects a collision or significant impact, the current clip can be locked so normal loop recording does not overwrite it.
Continuous dash-cam recording is write-intensive, particularly at 4K 60fps. Use a high-endurance card designed for sustained recording rather than a general-purpose consumer card.
No internal lithium battery; the camera uses a supercapacitor for in-vehicle reliability.
Direct status and settings access without requiring the app for every task.
Built-in audio recording and spoken status/error notifications.
Separate power, recording, GPS, microphone and Wi-Fi status indicators.
Slim coaxial cabling, a dual-port 45W charger and model-specific accessories are all part of the A329S ownership story.
The rear camera uses a slim coaxial cable with miniature connectors. Coaxial construction is less susceptible to electromagnetic and radio-frequency interference while maintaining the bandwidth required by the rear-camera feed.
The included 45W charger provides two USB-C outputs for the camera and another compatible mobile device, with an indicator light for easier use in the dark.
Reduces windscreen reflections and road glare before they are recorded. Rear CPL-600 is optional.
Protect the current clip with the centre button and assign shortcut functions to the two side buttons.
The dedicated cable diagram shows the front unit, rear camera and power/storage connections in one place.
The front CPL-200 is included. The compatible CPL-600 for the rear camera is sold separately.
The BTR200 can be positioned on the dashboard or another convenient surface within its quoted 5-metre operating range.
The A329S front unit supports compatible modules across the wider family, including interior, telephoto and waterproof-camera configurations. That gives the platform more upgrade flexibility than a fixed two-camera system.
Build around the standard A329S front unit with compatible standard camera modules.
The A329T family uses a compatible telephoto module for a second forward-looking perspective.
A329-series waterproof modules extend the platform beyond an interior rear-window camera installation.
The official installation guide covers the front unit, rear camera, cable routing and core connections.
Useful for planning camera position, cable routing and the rear-camera run before committing adhesive mounts.
The important purchase-driving features are explained above; use these sections for the exact technical detail.
microSD card, external SSD, SSD connection cable, HK4/HK6 hardwire kit, rear CPL-600 and BTR200 remote are optional unless purchased separately.
No. The front camera records 4K 60fps with HDR off. Enable HDR and the front switches to 4K 30fps. The rear camera records at 2K 30fps with HDR support.
The A329S adds 4K 60fps front recording, Wi-Fi 6, external SSD support up to 4TB, USB 3.0 direct transfer, Low Power Impact Detection, Hybrid Parking Mode and HK6 battery monitoring, while retaining STARVIS 2 front and rear imaging.
Yes, parking recording needs constant power with the engine off. HK4 supports the basic parking modes and cut-off time protection. HK6 adds Hybrid Parking Mode, cut-off voltage protection and Bluetooth battery-voltage display.
For normal driving and traditional parking modes, an SSD can be used on its own. For Low Power Impact Detection or Hybrid Parking Mode, keep a microSD card inserted because wake-up recordings from the low-power state are written to microSD.
Up to 512GB microSD and an external portable SSD up to 4TB. External SSD and the recommended VIOFO SSD cable are sold separately.
Wi-Fi 6 can reach up to 30MB/s on 5GHz under stated interference-free test conditions. Direct USB 3.0 transfer can reach up to 55MB/s on compatible hardware.
It combines footage from multiple cameras into a single split-screen video file, making multi-angle review and sharing easier without manually synchronising separate clips.
Yes. The CPL-200 front filter is included. The compatible CPL-600 rear filter is optional.
Yes. The A329S platform is modular and supports compatible additional camera modules across the wider A329S/A329T/A329SW family. For a conventional three-channel upgrade, the compatible A329S interior camera module can be added to the front unit.
The standard 6m cable suits most cars and compact SUVs. Longer 8m, 10m, 15m and 20m options are available for larger SUVs, pickups, vans and commercial vehicles; measure the intended headliner route rather than the vehicle's straight-line length.
