Biuone A20 Dual Dash Cam 1080P Front & Rear

Biuone A20 is a plug-and-play dual dash camera system that records front and rear 1080P video, delivers improved low-light detail, and saves events automatically with its G-sensor and loop-recording features.

If you want continuous, worry-free video capture for daily driving, rideshare work, or weekend trips, this dual dash cam pair (front + rear) arrives preloaded with a 32GB card, mounts with a simple suction bracket, and starts and stops with your car’s ignition via the included cigarette-lighter power cable. The front camera uses an f/1.8 aperture and WDR processing to improve contrast and night visibility, while the rear camera broadens coverage to reduce blind spots. Playback is available on the camera’s screen or on a computer using the supplied USB cable and card reader.

How clear are recordings at night and in mixed lighting?

The front lens pairs a wide f/1.8 aperture with WDR technology to preserve detail in shadows and highlights, making license plates and traffic signs easier to read after sunset or in tunnels. The rear camera also supports quality 1080P capture for better coverage of what’s behind you.

• Front: 1080P 30 fps with f/1.8 aperture for stronger low-light performance
• Rear: 1080P 30 fps with 140° field of view to reduce rear blind spots
• WDR processing balances bright and dark areas in the same frame
• Files stored in MOV format for straightforward computer playback

How does the dash cam protect important footage during an incident?

The Biuone A20 includes a G-sensor that detects significant impacts and automatically locks the current video file so it is not overwritten by loop recording. Loop recording continuously cycles footage so the 32GB card never fills permanently, while motion detection and parking monitoring capture activity when the car is stationary (requires constant power).

• Automatic G-sensor file locking for collisions or sudden jolts
• Loop recording overwrites oldest files to maintain continuous storage
• Motion detection and parking monitor save clips while parked (needs power)
• 32GB memory card included and pre-inserted for immediate use

How easy is installation and daily use?

Mounting is designed to be quick and tool-free: a suction cup secures the front unit to the windshield and the rear camera connects with a six-meter cable that can be routed discreetly. Power is supplied via the cigarette-lighter adapter so the cameras power on and off with the vehicle’s engine, removing the need to manage batteries or separate chargers.

• Suction-mount front bracket for fast windshield installation
• Rear camera cable (6 m) plugs into the front unit for a tidy run
• Cigarette-lighter power adapter enables auto on/off with ignition
• Plug-and-play operation—no smartphone app or Wi-Fi required

What playback and compatibility options are available?

Although the camera does not offer Wi‑Fi streaming or GPS logging, it supports on-device playback and computer review using the included USB cable or card reader. Video files are in MOV format and can be viewed on most modern media players for evidence review or trip highlights.

• Playback directly on the dash cam screen for quick reviews
• Transfer files to a computer via USB cable or SD card reader
• MOV format compatible with common desktop media players
• Audio can be muted easily from the device during use

Who is this for? The Biuone A20 dual dash cam suits drivers who want reliable front-and-rear recording without relying on smartphone apps or GPS. It’s a practical choice for commuters, rideshare drivers, families, and small-business vehicle owners who need continuous loop recording, impact protection, and improved nighttime visibility in an easy-to-install package.
