VIOFO A229 Pro 2CH 4K + 2K Dash Cam

4K ahead, 2K behind, in one compact system.

The VIOFO A229 Pro 2CH records 4K video of the road ahead and 2K video of following traffic, both at 30FPS. Sony STARVIS 2 sensors and HDR help it handle bright headlights and darker surroundings. A 2.4-inch screen helps you aim the cameras, and local Wi-Fi lets you review saved clips on your phone.

This package includes front and rear cameras only. There is no cabin camera. A front CPL-200 filter and an 18-month manufacturer warranty are included. A memory card, hardwire kit, rear CPL filter and remote are sold separately. Parking recording needs compatible constant power, such as the optional VIOFO HK4 hardwire kit.

Key features

• 4K front recording: 3840 × 2160 video at 30FPS from an 8MP Sony STARVIS 2 IMX678 sensor with a 140° field of view.
• 2K rear recording: a 5MP Sony STARVIS 2 IMX675 sensor with a 160° view keeps a clear record of traffic behind you.
• HDR and reflection control: HDR helps balance bright and dark areas, and the included CPL-200 filter reduces windshield reflections on the front camera.
• Dual-band Wi-Fi and GPS: review and download clips through the VIOFO app over 2.4GHz or 5GHz. GPS adds location, speed and time to your footage.
• Voice controls and notifications: save a clip or take a photo by voice. Spoken alerts help flag recording or memory-card problems.
• Buffered parking recording: with a hardwire kit, choose event, time-lapse or low-bitrate parking modes.

Parking recording and power

Parking recording requires constant power. The optional VIOFO HK4 hardwire kit supplies constant power, an ignition signal and a battery cutoff through the GPS mount's USB-C port. The current manual also lists HK6 support, and vehicle-voltage stamping requires the HK6.

• Buffered event recording saves triggered clips.
• Time-lapse creates condensed footage without audio.
• Low-bitrate mode records continuous video and audio in smaller files.
• Night Vision is available with 1FPS time-lapse.
• Up to three parking geofence zones can turn the camera off at chosen locations, such as a home garage.

Runtime depends on the power source, cutoff settings, temperature and recording mode. A switched vehicle socket stops powering the camera when it turns off.

Storage and connectivity

A high-endurance microSD card up to 512GB is required and sold separately. Both cameras save to the card in the front unit. Loop recording replaces older ordinary files; locked incident files also use finite space. Copy important clips promptly.

Privacy mode keeps only the latest four ordinary files in this two-camera setup, so leave it off if you want your normal recording history. Wi-Fi is a local camera-to-phone connection. There is no built-in LTE or cloud service for remote viewing, live tracking or parking push alerts, and this model does not record to an external SSD.

Setup and firmware notes

Clean the windshield, rear window and lenses, then aim each camera and check a test recording before finalizing installation. Adjust the front CPL filter while watching the live view to cut dashboard reflections. Set up the camera and practice voice commands while parked. Plan the rear cable route around trim and airbags before you start.

Use firmware for the exact A229 Pro model. Front and rear cameras use different files, and VIOFO advises against updating a rear camera that is working normally. Back up recordings and settings, keep stable power during updates, and recheck recording, HDR, audio and parking afterward.
