VIOFO A149 Pro Duo is a dual-channel dash camera designed for drivers who value detailed 4K video quality, fast connectivity, and intelligent parking protection.

The 4K resolution of the front camera, combined with the Sony STARVIS 2 IMX678 sensor, delivers sharp and detailed footage, while the rear camera records everything happening behind the vehicle in Full HD quality. HDR on both cameras helps preserve important details in challenging lighting conditions – whether driving during the day, at night, or using parking surveillance.

Recording Quality and Image Sensors

• 4K + Full HD recording – detailed 4K video at the front and 1080P video at the rear
• Sony STARVIS 2 IMX678 front sensor – 8 MP image sensor for clear and detailed recording, even in low-light conditions
• HDR on both cameras – balances bright and dark areas and helps improve license plate readability
• 140° front and 136° rear field of view – wide coverage of everything happening in front of and behind the vehicle
• 360° adjustable rear camera – allows the recording angle to be adjusted as needed

Convenience and Connectivity

• Wi-Fi 6, 2.4 GHz and 5 GHz – fast file transfers via the VIOFO mobile app, up to 30 MB/s according to the manufacturer
• Voice control – take photos, lock video clips, and control other functions using voice commands
• Built-in GPS with four satellite systems – supports GPS, BeiDou, Galileo, and GLONASS, recording location, speed, and time
• 2.0″ high-resolution display – convenient setup and live video preview
• Built-in Bluetooth – supports the optional BTR200 remote control

Safety and Parking Protection

• Loop recording – automatically overwrites the oldest unlocked recordings when the memory card is full
• G-sensor and emergency file locking – automatically protects important recordings from being overwritten when an impact is detected
• Quick lock button – allows important video clips to be protected manually with a single press
• Five parking modes – hybrid recording, low-power impact detection, automatic event detection, time-lapse recording, and low-bitrate recording
• Buffered event recording – in automatic event detection mode, footage from before and after an event is preserved
• Low-power impact detection – the camera remains in energy-saving standby mode and wakes up within 2 seconds after detecting an impact to record a one-minute clip
• Location-based parking surveillance control – allows users to define areas where parking recording is disabled or only low-power impact detection is used

Optional Accessories

• CPL-800 polarizing filter for the front camera (included in the package) – reduces reflections from the windshield and road surface while improving image contrast
• CPL-600 polarizing filter for the rear camera (optional accessory) – reduces reflections in rear camera recordings
