Overview

The Biuone A22W 4K Front and Rear Dash Cam arrived in mid-2024 as a budget-conscious option for drivers who want dual-channel coverage without a complicated setup or a steep price tag. This dual dash cam ships as a complete kit — 64GB card, dual-port USB charger, suction mounts, and a tool stick all included in the box. The front camera captures at 4K resolution while the rear handles 1080P, which is a reasonable split at this price tier. Expect solid daylight footage, but calibrate your expectations: true 4K performance at budget pricing comes with trade-offs that more expensive rivals don't have.

Features & Benefits

The front lens covers a wide 170° field of view while the rear manages 140°, which together do a solid job capturing lane changes and parking lot incidents. The built-in WiFi lets you pull up footage on your phone through the companion app — no SD card removal needed. The F1.6 aperture and 6-element glass lens help in tricky lighting, though night vision in truly dark conditions is adequate rather than exceptional. A G-sensor auto-locks collision clips so they won't get wiped by loop recording. One real caveat: the 24-hour parking mode demands a hardwire kit sold separately, which many buyers discover only after purchase.

Best For

This front and rear camera suits daily commuters who want a reliable, set-and-forget setup without wrestling with a complicated installation. Rideshare and delivery drivers will particularly appreciate the dual-channel coverage — having both front and rear angles documented can matter enormously in a dispute. First-time dash cam buyers get a gentle entry point: the included 64GB card and dual-port charger mean you're not hunting for accessories before you hit the road. Wide vehicle compatibility across cars, SUVs, trucks, and minivans makes it broadly practical. If you want WiFi app access without paying flagship prices, this Biuone dash cam covers the basics well.

User Feedback

Buyers generally praise this dual dash cam for its straightforward installation and the value of getting a memory card and charger bundled right in the box. The 3.0″ IPS screen earns positive mentions for its clarity. On the downside, some users run into trouble with the TS video format — your default media player likely won't open these files, so a compatible third-party player is necessary. The WiFi range tops out at around 3 to 5 meters, perfectly fine inside the car but nothing further. A handful of reviewers found night vision adequate on lit city streets but underwhelming on dark rural roads. Biuone's after-sales support is generally described as responsive.

Pros

  • Complete kit out of the box — 64GB card, charger, and mounts included from day one.
  • Front 4K and rear 1080P dual-channel coverage gives you evidence from both angles in one affordable unit.
  • 170° front and 140° rear wide-angle lenses capture a broad view that covers most blind spots.
  • Built-in WiFi lets you browse and pull footage from your phone without ever touching the SD card.
  • The F1.6 aperture and 6-element glass lens handle daytime and moderately lit night driving reasonably well.
  • G-sensor automatically locks collision clips so critical footage never gets overwritten during loop recording.
  • Compatible with cars, SUVs, trucks, minivans, pickups, and more — fits most vehicle types without issue.
  • Installation is straightforward enough for complete beginners, typically taking under 20 minutes.
  • The 3.0″ IPS display is clear and easy to navigate while parked.
  • Biuone offers a one-year warranty and lifetime technical support, which is reassuring at this price point.

Cons

  • 24-hour parking mode requires a separately purchased hardwire kit — it does not work straight out of the box.
  • TS video format is incompatible with most default media players, requiring an extra download to view footage on a computer.
  • Real-world 4K footage quality falls short of mid-range or premium dash cams in detail and dynamic range.
  • WiFi connectivity maxes out at roughly 3 to 5 meters, making remote viewing outside the car impractical.
  • Night vision performance on unlit roads is noticeably limited compared to cameras with dedicated low-light sensors.
  • The companion app has reported stability issues, with some users experiencing connection drops or lag during playback.
  • Loop recording is reliable but the camera lacks a dedicated event folder that is easy to navigate within the app.
  • No built-in GPS means there is no speed or location data overlaid on your footage for insurance purposes.

Ratings

The scores below reflect an AI-driven analysis of verified global buyer reviews for the Biuone A22W 4K Front and Rear Dash Cam, with spam, bot-generated, and incentivized feedback actively filtered out before scoring. Each category is evaluated against real-world usage patterns from commuters, rideshare drivers, and first-time dash cam owners worldwide. Both the strengths that keep buyers satisfied and the friction points that generate complaints are transparently baked into every score.

Value for Money
88%
For the price, getting a dual-channel setup with a 64GB card, a dual-port charger, and WiFi app control already included is genuinely hard to argue with. Most comparable kits at this tier charge separately for the memory card alone, making this front and rear camera feel like a well-rounded package for budget-conscious buyers.
The value equation gets a little shakier once you realize parking mode requires an additional hardwire kit purchase, which is not reflected in the sticker price. Buyers who factor that in after the fact feel slightly misled about the true out-of-box capability.
Video Quality (Daytime)
76%
24%
In full daylight, the 4K front camera delivers footage that reads license plates at reasonable distances and captures lane markings and road signs with enough clarity to be useful as evidence. Commuters and rideshare drivers consistently report the daytime picture being more than adequate for their practical needs.
It is not quite the same 4K experience you'd get from a mid-range or flagship camera — colors can look slightly washed out and fine edge detail softens at distance. Buyers who compare clips side by side with pricier rivals notice the gap, even if the footage is perfectly serviceable for everyday use.
Night Vision
61%
39%
On moderately lit suburban and city streets, the F1.6 aperture and HDR processing do enough work to keep footage watchable after dark, capturing headlights, brake lights, and basic road markings without total noise collapse. Urban commuters who drive in well-lit environments rarely flag night performance as a problem.
On poorly lit roads or in true darkness, the footage gets grainy fast and fine detail becomes difficult to read. Drivers who regularly travel on rural roads or unlit highways at night find the night vision noticeably limited compared to cameras with dedicated low-light or starlight sensors at higher price points.
Ease of Installation
91%
The suction cup mount, pre-cut cable, tool stick, and included cigarette lighter adapter mean most buyers get this dual dash cam up and running in under 20 minutes without touching a wiring diagram. First-timers especially appreciate that there is no guesswork — the manual covers the basics and the setup is genuinely plug-and-play for standard use.
Routing the rear camera cable neatly through the headliner and down to the back window takes considerably more effort and patience, particularly in larger vehicles like SUVs or minivans. A few buyers found the cable length tight for certain vehicle layouts and wished a longer rear cable was included.
WiFi & App Experience
58%
42%
When the app connects cleanly, being able to browse and download footage directly to your phone without removing the SD card is a genuine convenience, particularly for rideshare drivers who need to pull clips quickly after an incident. Initial pairing is straightforward for most iOS and Android users.
The 3 to 5 meter WiFi range means you must be sitting inside or standing right at the car door to maintain a stable connection, which limits real-world usefulness. App stability is a recurring complaint — dropped connections, slow video loading, and occasional crashes make the experience unreliable enough that some users simply remove the card instead.
Build Quality
72%
28%
The camera body feels solid enough for a budget unit, and the suction mount holds the device securely on the windshield even through bumpy roads and temperature swings. Buyers in warmer climates report no major warping or adhesion issues over several months of daily use.
The plastic housing feels noticeably lightweight compared to mid-range competitors, and a handful of buyers note the rear camera connector feels less than confidence-inspiring over repeated plugging and unplugging. It reads as a budget product when you hold it, even if it functions adequately.
Loop Recording
86%
Loop recording works reliably and quietly in the background — once set up, the camera handles card management on its own without any intervention needed. Drivers who run this Biuone dash cam every day appreciate that the oldest unlocked footage is cleanly overwritten without corrupting protected event clips.
There is no separate, easily navigable folder for locked G-sensor clips within the app, which makes finding a specific event clip after a long day of driving slightly tedious. Users who rely heavily on incident footage management would benefit from a smarter file organization system.
G-Sensor Reliability
74%
26%
The automatic collision lock works as intended in genuine impact scenarios, protecting critical footage from being erased during subsequent loop recording cycles. Drivers who have used it after minor fender-benders report the relevant clips were preserved and accessible without any manual action.
At the default sensitivity setting, the G-sensor can misfire on aggressive speed bumps, rough train crossings, or sudden braking — locking clips unnecessarily and gradually filling the protected storage folder. Adjusting sensitivity to a lower setting resolves the issue for most users, but it is not intuitive out of the box.
Display Quality
79%
21%
The 3.0″ IPS screen is bright and clear enough for navigating the settings menu and doing a quick review of footage while parked. The IPS panel offers decent viewing angles, which is a step above the TN screens common in cheaper dash cam units.
In direct sunlight, the display can wash out enough to make menu reading frustrating, particularly during summer driving. It is a functional screen for configuration, but not something you would rely on for detailed footage review — that is better done via the app or a proper monitor.
Parking Mode
47%
53%
When properly set up with a hardwire kit, the 24-hour parking mode does capture incidents while the vehicle is unattended, which is a meaningful feature for drivers who park in busy lots or city streets overnight.
The hardwire kit is not included and must be bought separately, meaning many buyers expect the feature to work out of the box and are disappointed when it does not. This single caveat significantly undermines the perceived value of the parking mode as a selling point for buyers who prioritize it.
Video Format Compatibility
43%
57%
The TS format does offer some resilience against power interruptions, preserving partial footage that MP4 recordings might corrupt entirely during a sudden shutoff — a practical advantage in accident scenarios where power cuts abruptly.
Most buyers do not know what TS format is until their files refuse to open on their computer or phone, which creates immediate frustration after a first drive. Needing to download a third-party player like VLC just to review footage is an unnecessary friction point that cheaper competitors have already solved by defaulting to MP4.
Wide-Angle Coverage
83%
The 170° front and 140° rear coverage genuinely captures a wide swath of the road environment, including adjacent lanes and pedestrian crossings, which proved useful for commuters navigating dense urban traffic. Rideshare drivers in particular value the broad rear angle for monitoring in-cabin blind spots during pickups.
Extreme wide-angle lenses introduce some barrel distortion at the edges of the frame, which can make objects near the periphery look slightly stretched. This is standard for wide-angle dash cams at any price, but buyers expecting photographic accuracy at the edges will notice it.
After-Sales Support
71%
29%
Biuone's stated one-year warranty and lifetime technical support via email give buyers a reasonable safety net, and a portion of users report getting responsive replies within a day or two when accessory issues or setup questions arose. The willingness to replace missing components is flagged positively by several reviewers.
Email-only support can feel slow for buyers who encounter an urgent issue immediately after purchase, and response quality varies depending on the nature of the problem. Users dealing with more technical issues like app bugs or firmware questions reported less satisfying resolutions compared to those with simple accessory requests.

Suitable for:

The Biuone A22W 4K Front and Rear Dash Cam is a practical pick for everyday commuters who want dual-channel protection without a steep learning curve or a complex installation process. It makes particular sense for rideshare and delivery drivers who need documented front and rear footage as routine protection against false claims or disputed incidents. First-time dash cam buyers will appreciate the all-in-one kit format — the 64GB card, dual-port USB charger, and mounting hardware are already in the box, so you're not piecing together accessories before your first drive. Budget-conscious drivers of SUVs, trucks, minivans, or sedans who want WiFi app access for quick video playback will find the core feature set covers their needs without overpaying. If your priority is basic, reliable dual-camera coverage at an accessible price, this front and rear camera delivers a reasonable return on a modest investment.

Not suitable for:

Drivers who depend heavily on parking surveillance should know upfront that 24-hour parking mode requires a hardwire kit sold separately — this dual dash cam does not support it out of the box, which is a genuine inconvenience many buyers overlook. Anyone expecting flagship-grade 4K image quality will likely be disappointed; at this price tier, real-world footage is adequate but noticeably behind dedicated higher-end units in color accuracy and fine detail, especially in challenging lighting. Users who frequently drive on unlit rural roads at night may find the night vision performance underwhelming compared to cameras equipped with dedicated infrared sensors. Tech-averse buyers could be caught off guard by the TS video format, which requires a third-party media player since most default desktop and mobile players won't open it natively. If seamless app connectivity or a wide WiFi range is critical to your workflow, the stated 3 to 5 meter limit of this Biuone dash cam may frustrate you, particularly if you want to review footage from outside the vehicle.

FAQ

The 64GB card is included in the box, but you will typically need to insert and format it yourself before first use. The on-screen menu walks you through the format process in just a few taps, so it takes under a minute.

Yes, this front and rear camera supports higher-capacity microSD cards beyond the included 64GB — most buyers use cards up to 128GB or 256GB without issues. Just make sure to use a Class 10 or UHS-I rated card for reliable 4K write speeds, and format it in the camera before use rather than on your computer.

Not automatically. The 24-hour parking mode on this dual dash cam requires a hardwire kit, which connects the camera directly to your vehicle's fuse box so it receives power even when the engine is off. That kit is not included in the box and needs to be purchased separately, so factor that in if parking surveillance is a priority for you.

The companion app is free to download on both the App Store and Google Play. You connect by enabling Wi-Fi on the camera, then joining its network from your phone's settings before opening the app. Keep in mind the Wi-Fi signal only reaches about 3 to 5 meters, so you need to be inside or right next to the car to use it.

The Biuone A22W 4K Front and Rear Dash Cam saves footage in TS format rather than the more common MP4, which is why most default media players on Windows or Mac won't open them. Downloading a free player like VLC solves the problem instantly — just open the file with it and you're good to go.

The G-sensor monitors for sudden jolts or impacts while you're driving. When it detects one, it automatically locks the current clip so loop recording can't overwrite it later. Most cameras in this category let you set the sensitivity to low, medium, or high through the settings menu, which is worth doing — the default setting can sometimes lock clips for minor bumps like speed bumps or potholes.

On well-lit city streets and highways with ambient lighting, this front and rear camera handles nighttime footage reasonably well thanks to the F1.6 aperture and HDR processing. On completely unlit rural roads, it shows its budget-tier limitations — footage can look grainy and detail drops off. If most of your night driving is in urban areas, it should be adequate; if you regularly drive in total darkness, a camera with dedicated infrared or starlight sensors would serve you better.

Many drivers hardwire their own dash cams at home using a basic fuse tap kit and a multimeter, and there are plenty of walkthrough videos online for the process. That said, if you're not comfortable working around your car's fuse box, having a car audio shop do it takes about 30 minutes and usually costs a small fee. Either way, the hardwire kit itself is a separate purchase.

The rear camera connects to the front unit via a cable and relies on the main unit for power and recording control — it does not operate on its own. Both cameras record simultaneously whenever the front unit is powered on, and the display on the main unit lets you switch between the two feeds.

The TS video format the camera uses is specifically designed to handle abrupt power cuts, preserving whatever footage was captured up to that point rather than corrupting the entire file. Locked event files from the G-sensor are stored in a protected folder that loop recording won't touch, so collision clips are generally safe even after an unexpected shutdown.
