Just last week, I was cruising down the M25 during rush hour. Traffic was its usual stop-and-go self when the car in front of me slammed on its brakes for no apparent reason. I reacted in time, but the driver behind me wasn’t so lucky. The crunch of metal was sickening. In the chaotic aftermath, with fingers pointing and stories changing, I felt a wave of relief wash over me. Not just because I was unharmed, but because my silent, electronic witness was already saving the evidence. This is the reality of driving today; an incident can happen in a split second, and without clear proof, you’re left in a frustrating “he said, she said” situation that can cost you time, money, and your no-claims bonus. A reliable dash cam is no longer a gadget for tech enthusiasts; it’s an essential piece of safety equipment for every driver.

What to Consider Before Investing in an On-Dash Camera System
An On-Dash Camera is more than just a device that records video; it’s a key solution for peace of mind, insurance claim validation, and personal security. In an era of increasing road incidents and insurance fraud, having an impartial, high-definition recording of events is invaluable. It captures everything from fender-benders to breathtaking scenic drives, acting as your vehicle’s black box. The primary benefit is irrefutable evidence, but it also encourages better driving habits and can even deter potential road rage incidents or vandalism when parked. The right dash cam transforms your windscreen from a simple piece of glass into an intelligent observation post, constantly guarding your interests.
The ideal customer for a product like the IIWEY EY02 4K Dual Dash Cam is a daily commuter, a professional driver, a new driver, or anyone who spends significant time on the road and wants a ‘set-and-forget’ safety net. They value high-resolution video for capturing details like license plates and prefer a discreet, screen-less design that doesn’t obstruct their view. However, this type of app-controlled camera might not be suitable for those who are less tech-savvy or prefer the immediate feedback and control of a physical screen. For them, a model with an integrated LCD display might be a more comfortable choice, even if it’s less stealthy.
Before investing, consider these crucial points in detail:
- Video Resolution & Coverage: This is paramount. 4K (2160p) resolution on the front camera, like that offered by the IIWEY EY02, provides exceptional clarity for identifying license plates and street signs from a distance. A dual-camera system with a 1080p rear camera ensures you’re covered from both ends. Pay close attention to the field of view; a 160-degree angle provides wide coverage of multiple lanes without significant “fisheye” distortion.
- Power Source & Durability: Traditional dash cams use lithium-ion batteries, which can degrade and even become a safety risk in extreme heat or cold. The IIWEY EY02 uses a supercapacitor, a modern solution that is far more resilient to temperature fluctuations. This dramatically increases the device’s lifespan and reliability, making it a crucial feature for a device that lives on your windscreen.
- Connectivity & Data Management: How easily can you access your footage? Models with built-in Wi-Fi, especially the faster 5GHz band, allow you to connect directly to the camera with your smartphone. This makes it simple to review, download, and share critical clips without the hassle of removing the SD card and finding a computer. App control is the modern standard for screen-less dash cams.
- Installation & Form Factor: Do you want a large, obvious device or something that blends in? A compact, no-screen design is far more discreet and less likely to attract the attention of thieves. Installation should be straightforward, typically involving 3M adhesive pads and routing cables around the trim of your car. Check that the included cables are long enough for your specific vehicle.
Making the right choice ensures you have a reliable witness when you need it most. It’s an investment in your safety and financial protection on the road.

First Impressions: Sleek, Compact, and Purpose-Built
Unboxing the IIWEY EY02 4K Dual Dash Cam, the first thing that struck us was its minimalist and premium feel. The main front camera unit is surprisingly small and lightweight (just 150 grams), finished in an attractive silver that feels cool and solid to the touch. This isn’t a bulky, distracting gadget; its “hidden” no-screen design is clearly intended to nestle discreetly behind the rear-view mirror, a true ‘fit and forget’ philosophy. Inside the box, we found everything needed for a clean installation: the 4K front camera, the 1080p rear camera, a long USB-C power cable, a rear camera extension cable, 3M adhesive mounts, and, impressively, a free 64GB microSD card. Including the SD card is a fantastic touch, as it means you can get up and running immediately without an extra purchase—a detail many competitors overlook. The use of a modern USB-C port is another sign of quality, promising a more robust and reliable connection than older micro-USB standards. The overall impression is of a well-thought-out package that prioritizes stealth and performance over flashy, unnecessary features. You can see its full feature set and clean design here.

- Supercapacitor power source for superior heat resistance and longevity.
- Fast 5GHz Wi-Fi for quick video downloads to your phone.

A Deep Dive into the IIWEY EY02’s On-Road Performance
A dash cam’s spec sheet only tells half the story. To truly understand its worth, you have to get it on the road, testing it through bright sunshine, pouring rain, and dark country lanes. We spent several weeks with the IIWEY EY02 4K Dual Dash Cam installed in our daily driver, evaluating everything from its installation process to its real-world video quality and app functionality. Here’s our detailed breakdown.
Installation and Setup: A 20-Minute Job for Lasting Peace of Mind
Getting the IIWEY EY02 4K Dual Dash Cam up and running was a refreshingly straightforward process. The “set and forget” ethos is evident from the start. The front camera attaches to the windscreen via a sturdy 3M adhesive pad, which we found held firm throughout our testing. We positioned it just behind the rear-view mirror, making it almost invisible from the driver’s seat. One user noted it’s “nice and discreet,” and we wholeheartedly agree. The camera itself unclips from the mounting point, a thoughtful feature if you want to stow it away when parked in a high-risk area.
Routing the USB-C power cable and the rear camera cable was the most time-consuming part, but it’s manageable for anyone with a bit of patience. We tucked the wires into the headliner and down the A-pillar for a clean, factory-installed look. The provided cables were just long enough for our mid-size hatchback, but as one user with a larger vehicle mentioned, “it would be better if the cables were slightly longer.” This is a key consideration for owners of SUVs or estates. The rear camera is tiny and adheres easily to the back window. Once both cameras were powered up, connecting to the app via the built-in 5GHz Wi-Fi was seamless. The app (we used OKCAR) immediately found the camera, and we were able to see a live view and access all the settings, such as resolution, loop recording duration, and G-sensor sensitivity, right from our phone. While some users reported initial connection difficulties, we found it connected reliably every time we got in the car. Overall, from unboxing to fully operational took us less than 30 minutes.
Day and Night Video Quality: Capturing the Critical Details
This is where the IIWEY EY02 4K Dual Dash Cam truly shines, especially given its price point. The front camera’s 4K (2160p) resolution is genuinely impressive. During daylight hours, the footage is sharp, vibrant, and packed with detail. We were easily able to read license plates of cars two to three lengths ahead, even when moving. The 160-degree wide-angle lens provides excellent coverage of the road without excessive distortion at the edges. One user confirmed our findings, stating, “Video quality is very good and can make out license plates of other vehicles even in dusk.” We found this to be true; as the sun began to set, the Wide Dynamic Range (WDR) technology did an admirable job of balancing the bright sky with the darker shadows on the road, preventing crucial details from being washed out or lost in darkness.
Night vision performance is often the Achilles’ heel of budget-friendly dash cams, but the EY02 held its own. The combination of the high-performance CMOS sensor and large aperture lens produces footage that is surprisingly clear and well-lit in urban environments with streetlights. On unlit country roads, it relies heavily on the car’s headlights, but the image remains usable and clear enough to make out the road layout and other vehicles. The 1080p rear camera, while not as stunning as the 4K front, is more than adequate for its purpose. It clearly captures the context of what’s happening behind the vehicle, which is crucial for rear-end collision disputes. One technical user pointed out that the files are recorded in the efficient HEVC (H.265) codec, which maintains high quality while creating smaller file sizes—a smart feature that maximizes the storage space on the included 64GB card. For anyone prioritising visual evidence, this dash cam’s video performance is a major selling point.
App Control and Core Features: Smart, Simple, but Not Without Flaws
Living with a screen-less dash cam means relying entirely on its companion app, and for the most part, the experience with the IIWEY EY02 4K Dual Dash Cam is positive. The 5GHz Wi-Fi is noticeably faster than the older 2.4GHz standard found on many competitors. This makes a real difference when you need to download a large 4K video file to your phone; what could take several minutes on an older device is done in under a minute here. As one reviewer wisely noted, “For clearer viewing of recordings, make sure to actually download first to device.” Streaming 4K video over Wi-Fi can be choppy, but downloaded files play back perfectly smoothly.
The app provides access to all essential functions. You can format the SD card, adjust the G-sensor sensitivity (which automatically locks footage in the event of a collision), and enable parking mode (which requires a separate hardwire kit). The recently added voice control features are a nice touch, allowing for hands-free operation to ‘Take Photo’ or ‘Lock the Video’—useful for capturing something interesting without taking your hands off the wheel. However, this is also where we must address the most significant concerns raised in user feedback. Several users reported serious software problems, including corrupted video files and the camera failing to record entire journeys. One user had a near-miss on the motorway only to find the camera hadn’t recorded anything. Another experienced persistent memory card errors across multiple cards. While our test unit performed reliably, these reports suggest a potential quality control issue. This is a critical point of failure for a safety device, and it’s a gamble that potential buyers must be aware of despite the device’s many strengths. The supercapacitor is a definite highlight, ensuring the camera operates flawlessly in both freezing winter mornings and hot summer days, a feature that really sets it apart for long-term reliability compared to battery-powered units.
What Other Users Are Saying
After compiling feedback from numerous owners, a mixed but largely positive picture of the IIWEY EY02 4K Dual Dash Cam emerges. On the positive side, many users echo our sentiment about the device’s value and discreet nature. One satisfied customer stated, “It deserves what I paid for it. Easy installation, clear video front, back and the most important is reliable.” Another praised its simplicity, saying it was perfect for them as they “did not involve to request someone else to install it.” The inclusion of the 64GB SD card is frequently mentioned as a major plus, saving buyers time and money.
However, the negative feedback highlights a crucial theme of inconsistency. The most severe complaint revolves around reliability. One user called it a “windscreen ornament,” detailing issues where it “fails to read the memory card and needs formatting 75% of the time” and noting that the rear camera port eventually broke. Another returned two separate units due to file system corruption and unplayable videos. Other more minor, but still significant, issues include the rear camera causing interference with DAB radio in a Ford Kuga and the adhesive mount failing after just 2.5 months for one driver. This feedback is essential; while many users have a flawless experience, a notable minority have encountered significant hardware or software faults that undermine the product’s primary function as a safety device.
How Does the IIWEY EY02 Compare to the Alternatives?
The IIWEY EY02 4K Dual Dash Cam operates in a very competitive market. While it offers a fantastic set of features for its price, it’s important to see how it stacks up against other popular models. For buyers who might want a physical screen or built-in GPS, exploring these alternatives is a smart move.

The ORSKEY offers a very similar core specification to the IIWEY EY02, with a 4K front and 1080p rear camera, 5GHz Wi-Fi, and an included 64GB SD card. The most significant difference is the inclusion of a 2.0-inch display. This makes it a better choice for users who prefer to change settings directly on the device or want immediate visual confirmation that the camera is recording and aligned correctly, without having to connect their phone. If you’re wary of a purely app-controlled experience and don’t mind a slightly less discreet form factor, the ORSKEY is a very compelling alternative.

Final Verdict: A Capable 4K Dash Cam with a Reliability Caveat
The IIWEY EY02 4K Dual Dash Cam presents a truly compelling value proposition. On paper and, for the most part, in practice, it delivers on its promises. The 4K front video quality is excellent, the supercapacitor is a huge plus for long-term durability, and the fast 5GHz Wi-Fi makes managing footage a breeze. Its discreet, screen-less design is perfect for drivers who want a non-intrusive safety device that simply does its job in the background. Including a 64GB SD card adds to the already impressive value.
However, we cannot ignore the recurring reports of software and hardware failures from a segment of users. While our unit performed well, the risk of receiving a faulty device with issues like file corruption or recording failures is a significant concern for a product designed for security. Therefore, our recommendation is conditional. If you are looking for a feature-packed, budget-friendly 4K dual dash cam and are willing to accept the potential risk of reliability issues, the IIWEY EY02 is a fantastic choice that punches well above its weight. For those seeking absolute, mission-critical reliability, investing a bit more in a model from a brand with a more established track record might be the safer bet. If its feature set aligns with your needs, we believe it’s a worthy contender, and you can check the latest price and availability for yourself.
