2-channel 4K front and 2K rear HDR dash cam

The A229 Pro uses dual Sony STARVIS 2 cameras to deliver 4K front and 2K rear recording with excellent detail day and night.

IMX678 and IMX675 sensors: less noise, less motion blur

The front uses the IMX678 and the rear the IMX675 — both Sony STARVIS 2 sensors. Compared with original STARVIS technology, they offer wider dynamic range and higher light sensitivity, reducing noise and motion blur in day and night recording.

4K Ultra HD front recording

The front camera uses a Sony STARVIS 2 1/1.8" 8MP sensor to record in 4K. The higher pixel count delivers greater clarity, capturing number plates and road detail clearly even at speed, day or night.

2K rear recording

The rear camera records in 2K using a Sony STARVIS 2 1/2.8" 5MP sensor. The sensor delivers 2.5 times wider dynamic range than a STARVIS pixel of the same size, producing sharp, clear footage day and night.

2-channel HDR for clear number plates

HDR is active on both cameras, balancing bright and dark areas to preserve 4K and 2K detail across a wide range of lighting conditions — including capturing number plate detail at speed.

5GHz Wi-Fi for faster video downloads

The built-in 5GHz Wi-Fi module provides faster data transfer than 2.4GHz, making video previewing, downloading and sharing via the VIOFO app noticeably quicker.

USB 2.0 port for direct downloads to your phone

A USB 2.0 Type-C port lets you connect directly to a smartphone for photo and video downloads at up to 20MB/s on iPhone 16. The same connection can be used for firmware updates.

Smart voice control and notification

Voice commands let you start recording, take photos and toggle Wi-Fi in English, Chinese, Russian and Japanese. The A229 Pro also gives audio notifications for settings changes and memory card errors.

Accurate GPS tracking

The quad-mode GPS module supports GPS, BeiDou, Galileo and GLONASS for fast positioning and reliable accuracy. Location, speed and time data are embedded in recordings and viewable in the VIOFO app or on a computer.

Parking mode

The A229 Pro supports auto event detection, time-lapse and low-bitrate parking modes. Continuous parking mode recording requires the Viofo HK4 hardwire kit, which provides a permanent power connection with low-voltage cut-off to protect your car battery.

Storage

The A229 Pro accepts microSD cards up to 512GB. For reliable continuous recording, a high-endurance card such as the Viofo 512GB U3 A2 V30 microSD card is recommended.
