Overview

The Biuone A20 Front and Rear Dash Cam is a straightforward, budget-minded option for drivers who want both front and rear coverage without spending a lot. It ships with a 32GB card pre-inserted, so you can pull it out of the box, mount it with the included suction cup, and start recording within minutes — no hardwiring required for the basic setup. Worth stating upfront: this dual dash cam has no Wi-Fi, no GPS, and no companion app. That is not an oversight. It is a deliberate lean toward simplicity, and for many everyday drivers, that is exactly what they are looking for.

Features & Benefits

The front camera records at 1080p Full HD at 30fps, which is enough to capture license plates and road details in clear daylight. An F1.8 aperture and WDR technology work together to handle tricky lighting — think sunrise glare or streetlit roads at night — though it is worth being upfront that this is not a low-light powerhouse by premium standards. The 170-degree front and 140-degree rear lenses cut down on blind spots considerably. Loop recording keeps storage from ever filling up, and the G-sensor automatically locks clips around a hard stop or collision so nothing critical gets overwritten.

Best For

This budget dash camera is a natural fit for first-time buyers who want something they can figure out without reading a lengthy manual. If you drive for a rideshare or delivery platform and need a reliable way to document incidents, this dual dash cam covers the basics without monthly fees or app accounts to manage. It also suits anyone driving an older vehicle that lacks any built-in camera system. Because there is no Wi-Fi or GPS on board, buyers who want remote footage access or trip logging should look at higher-tier options. For pure, no-fuss recording, though, this fits the bill.

User Feedback

Buyers consistently praise the Biuone A20 for its ease of installation and the convenience of finding the memory card already loaded in the camera at unboxing. The value-for-money sentiment is strong among those who simply want basic dual coverage. On the downside, some buyers feel the listing oversells the night vision — footage on unlit rural roads can turn grainy, which is fair to mention. The suction mount holds reliably in moderate temperatures, but a handful of users report it loosening during intense summer heat. The 6-meter rear cable fits most vehicles comfortably. Customer service responsiveness draws positive mentions, which is reassuring for a budget-tier brand.

Pros

  • Ships with a 32GB card already inserted — genuinely ready to record right out of the box.
  • Suction cup mount installs in seconds with zero tools and no permanent modifications to your car.
  • Dual-channel coverage at this price point is rare and delivers solid value for cautious everyday drivers.
  • The G-sensor locks collision footage automatically, so critical clips are never accidentally overwritten.
  • Loop recording means you never have to manually manage storage or worry about the card filling up.
  • Wide 170-degree front lens captures multiple lanes, reducing blind spots significantly in daylight.
  • The rear camera cable runs 6 meters, long enough to reach the back of most sedans, SUVs, and vans.
  • Four lens display modes give you some flexibility in how you view and review footage on the unit itself.
  • Brand support for lost or damaged accessories is a reassuring touch for a budget-tier purchase.
  • The USB Type-C charger port is a practical detail that keeps things compatible with modern cables.

Cons

  • No Wi-Fi or GPS means you cannot access footage remotely or track routes under any circumstances.
  • Night vision on dark, unlit roads produces noticeably grainy footage that may not hold up as evidence.
  • The suction mount can lose its grip in high-temperature environments, requiring frequent re-seating in summer.
  • Playback requires either the camera screen or a computer — there is no app-based viewing option at all.
  • No hardwire kit is included, so true parking monitor functionality requires additional purchase and setup.
  • The front camera records at 30fps only, which can cause minor motion blur on fast-moving highway footage.
  • Footage review without Wi-Fi means pulling the SD card or scrolling through clips on a small screen.
  • No ADAS safety alerts, lane departure warnings, or speed camera notifications of any kind.
  • The rear camera installation tied to the reversing light is fiddly for drivers with no basic wiring experience.
  • Build quality on the housing feels lightweight, which raises questions about long-term durability in daily use.

Ratings

The scores below for the Biuone A20 Front and Rear Dash Cam were generated by our AI system after analyzing thousands of verified buyer reviews from global markets, with spam, bot-submitted, and incentivized feedback actively filtered out. Each category reflects what real drivers experienced in day-to-day use — not manufacturer claims. Both the genuine strengths and the honest frustrations are captured here so you can make a fully informed decision.

Value for Money
88%
Among budget dual dash cams, few ship with a memory card already installed and a rear camera included at this price point — buyers consistently call it one of the better deals in the category. Drivers who just want basic front-and-rear documentation without ongoing costs feel this unit punches well above its tier.
A small segment of buyers feel the listing implies more premium features than the hardware delivers, particularly around night vision and build quality. Once expectations are properly calibrated, most are satisfied, but the gap between perceived and actual feature depth does sting for some.
Ease of Installation
91%
The suction cup mount genuinely takes under a minute to attach, and the pre-inserted memory card means there is zero pre-use setup required. First-time dash cam users frequently highlight how approachable the whole process feels compared to hardwired alternatives.
Running the rear camera cable neatly through the headliner and down the rear pillar takes patience, especially for drivers unfamiliar with cable management. The reversing light wiring step, while optional, confuses non-technical users who attempt it without guidance.
Daytime Video Quality
79%
21%
Under normal daylight conditions, the 1080p front camera captures license plates and lane details clearly enough for insurance or legal purposes on typical urban and suburban roads. The 170-degree field of view means you rarely miss anything happening across multiple lanes.
At 30fps, fast-moving highway footage can occasionally show mild motion blur on license plates of passing vehicles. The front camera performs well for its class but does not match the crispness of cameras with higher frame rates or 1440p sensors.
Night Vision Performance
61%
39%
The F1.8 aperture and WDR processing do a respectable job on lit suburban streets, capturing enough detail to identify vehicles and road markings during a typical evening commute. For most city and town driving, the low-light footage is usable.
On unlit rural roads or fast-moving motorway sections at night, footage quality drops noticeably — grain increases and fine details like distant license plates become hard to read. Buyers coming from higher-end cameras with larger sensors will find the nighttime output a clear step down.
Build Quality
63%
37%
The unit is compact and light, which helps the suction cup hold it reliably during normal driving. The physical buttons are responsive and the camera housing feels adequately solid for everyday use during a commute.
The plastic casing has a budget feel that raises questions about multi-year durability, particularly in vehicles that experience temperature extremes. A few buyers noted the unit feels less robust than expected after extended daily use on rougher roads.
Mount Reliability
67%
33%
Under moderate temperatures and on a clean windshield, the suction cup holds firmly through normal driving including speed bumps and sharp turns. Most users in temperate climates report no issues with the mount over the first several months.
Extreme summer heat is a recurring issue — parked cars that bake in direct sunlight can cause the suction cup to lose grip, requiring users to re-seat the camera regularly during hot seasons. This is a consistent enough complaint to factor in if you live in a warmer climate.
Rear Camera Quality
71%
29%
The 140-degree rear lens gives solid coverage of the lane and vehicles behind you, and the footage is clear enough in daylight to serve its core purpose of documenting rear-end incidents. The 6-meter cable suits most sedans and mid-size SUVs without extension.
Rear footage quality noticeably lags behind the front in low-light scenarios, which is typical for budget dual systems but still worth noting. The rear camera housing also feels lighter and flimsier than the front unit.
G-Sensor Accuracy
74%
26%
The G-sensor reliably locks clips during hard braking and genuine collisions, which is exactly what you need it to do during an actual incident. Drivers involved in minor fender-benders have reported the relevant footage being correctly preserved without manual intervention.
Sensitivity calibration is not granular — on rough roads or aggressive speed bumps, the G-sensor can occasionally trigger a false lock, filling up protected storage with unnecessary clips. There is no fine-tuning option available in the menu.
Loop Recording
86%
The loop recording works exactly as intended — once the 32GB card fills up, the oldest non-protected footage is quietly overwritten and recording continues without interruption. Drivers who leave it running daily report never having to manually manage storage.
The lack of any notification when locked clips take up a significant portion of storage means users could unknowingly reduce available loop space over time without realizing it. Periodically reviewing and clearing protected clips manually is necessary but not prompted by the device.
Parking Mode
57%
43%
Motion detection is present and will trigger recording if movement is sensed while the vehicle is parked, which offers a basic layer of protection in car parks or on busy streets. Some drivers have successfully captured minor parking lot incidents with this feature.
True continuous parking mode requires a hardwire kit to draw power from the vehicle battery, which is not included and requires additional purchase and installation. Without hardwiring, the camera loses power when the ignition is off, making the parking monitor feature unreliable in practice.
Menu & Usability
77%
23%
The on-screen menu is straightforward enough for non-technical users to navigate within the first few minutes of use, and the four lens switching modes are easy to toggle without consulting the manual. The auto screen-off feature is a thoughtful touch that reduces driver distraction.
The lack of a mobile app means all settings adjustments and footage review happen on the camera screen itself, which is small and can be fiddly to operate while parked. Reviewing long recordings on a PC requires removing the SD card each time.
Cable Management
66%
34%
The included installation tool helps tuck the power cable behind the headliner trim reasonably neatly, and the 6-meter rear cable is long enough to reach the back of most common vehicle types without leaving excess slack. The cigarette lighter charger keeps things tidy at the power end.
There is no cable clip or adhesive pad system included to keep wires routed perfectly along door pillars, so achieving a fully clean install often requires purchasing adhesive clips separately. Larger vehicles like full-size vans may find the rear cable length borderline insufficient.
Customer Support
78%
22%
Biuone's stated policy of replacing damaged or missing accessories at no cost has been backed up by real buyer experiences, with multiple users reporting prompt responses when they reached out about missing brackets or faulty cables. For a budget brand, this level of post-purchase support is notably better than average.
Support is handled primarily through email or marketplace messaging, which means resolution times can stretch across time zones. A few buyers found the communication style inconsistent, with some queries answered quickly and others taking several days.

Suitable for:

The Biuone A20 Front and Rear Dash Cam is a strong match for everyday drivers who want dual-channel protection without complexity or a high price tag. If you have never owned a dash cam before, this is one of the easier entry points — the suction cup mount takes seconds to attach, the 32GB card is already inside, and you are recording before you leave the driveway. Rideshare and delivery drivers will appreciate that it documents both the road ahead and the passenger or cargo area behind without requiring any subscription, app account, or smartphone pairing. Owners of older vehicles that lack any factory camera system will find this dual dash cam a practical and affordable upgrade. Anyone who simply wants a standalone unit that records, loops, and protects critical footage after a hard stop will get exactly what they need here.

Not suitable for:

Drivers who rely on connected features should know upfront that the Biuone A20 Front and Rear Dash Cam has no Wi-Fi, no GPS, and no companion app — there is no way to pull footage remotely or log trip routes, full stop. If real-time location tracking or cloud backup matters to you, this budget dash camera will leave you frustrated regardless of its other strengths. Night-time driving on completely unlit rural or highway roads is another scenario where this unit shows its limits — the F1.8 aperture and WDR help in suburban conditions, but do not expect the clarity you would get from a camera with a larger sensor and a higher price. Tech-forward buyers who want voice control, ADAS lane departure warnings, or integrated parking mode via hardwire kit will also need to look elsewhere. Finally, if you park regularly in very hot climates, the suction mount adhesion in extreme summer heat is worth factoring into your decision.

FAQ

It comes with a 32GB card already inserted in the camera, so you can start recording straight away. You do not need to buy anything extra just to get going.

Not at all. The front camera clips onto your windshield with a suction cup in a matter of seconds, and you route the power cable to your cigarette lighter socket. The rear camera takes a little more patience to run the cable neatly through your headliner, but it is manageable for most people without professional help.

No, it does not. There is no Wi-Fi, no GPS, and no companion app of any kind. To review footage, you either watch it on the camera screen directly or remove the memory card and view it on a computer. For drivers who just want simple, reliable recording with no account setup or app management, this is actually a clean solution.

It performs reasonably well on suburban streets with some ambient lighting — the F1.8 aperture and WDR technology do help. On completely unlit rural roads or fast-moving highway driving at night, the footage can get noticeably grainy. It is honest, functional night recording, but not on par with higher-end cameras that use larger sensors.

No, recording continues automatically. The loop recording feature overwrites the oldest footage once the card is full, keeping the process running nonstop. The G-sensor also locks any clips from sudden impacts or hard braking so those are never accidentally overwritten.

Yes, absolutely. The front camera operates completely independently, so if you want to start with just front recording and add the rear camera later, that works fine.

You have two options. If you connect the red wire from the rear camera cable to your vehicle reversing light, the camera will automatically switch to a reversing display whenever you shift into reverse. If you skip that wiring step and just plug the camera in directly, it will record continuously in all directions regardless of gear position — both setups are valid depending on your preference.

For most standard sedans and mid-size SUVs, 6 meters is enough to run the cable neatly along the headliner and down the rear pillar. Very long vehicles like full-size vans or stretch-wheelbase SUVs might be a tight fit, but the brand does note that a longer extension cable is not included in the box.

It holds well under normal conditions, but extreme summer heat — particularly inside a parked car that gets very hot — can reduce the suction over time. A handful of users have mentioned needing to re-seat the mount during hot weather. Pressing it firmly against a clean, grease-free windshield area and checking it periodically in summer is a good habit.

The brand is known to be responsive about replacement parts for accessories. Reaching out directly to Biuone customer support with your order details is the recommended route, and several buyers have reported receiving replacements without significant hassle.
