It was a grey Tuesday afternoon, the kind where drizzle slicks the roads and everyone seems to be in a bigger hurry than usual. I was navigating a busy roundabout when a car to my left, without indicating, decided my lane was its lane. A screech of tyres, a jolt of adrenaline, and a near-miss that left my heart pounding against my ribs. In that moment, the thought that flashed through my mind wasn’t just relief, but a chilling ‘what if?’. What if they had hit me? It would have been my word against theirs, a stressful, murky situation with no impartial witness. This is the daily gamble we take on the road. The lack of a definitive record can turn a straightforward incident into a prolonged insurance nightmare, or worse. An extra set of eyes, one that never blinks and never forgets, isn’t a luxury anymore; it’s a fundamental piece of modern driving safety.

What to Consider Before Investing in an On-Dash Camera System
An On-Dash Camera, or dash cam, is more than just a gadget; it’s a key solution for peace of mind, accountability, and security on the road. It serves as your unbiased witness in the event of an accident, helps deter vandalism when parked, and can even capture unexpected moments, from stunning scenery to bizarre traffic incidents. The core benefit is irrefutable video evidence, which can expedite insurance claims, protect you from fraudulent ‘crash-for-cash’ scams, and provide clarity in any dispute. In today’s driving environment, having a reliable record of events is invaluable.
The ideal customer for a product like the GKU 4K Dash Cam Front and Rear Dual GPS 64GB is any driver who spends significant time on the road, from daily commuters and professional drivers to families on road trips. It’s for the cautious driver who wants to protect their no-claims bonus and the new driver seeking an extra layer of security. However, it might not be the best fit for someone who uses their car very infrequently or is unwilling to run a cable for a rear camera. For those seeking only the most basic forward-facing protection, a simpler, single-camera unit might suffice. But for comprehensive, 360-degree awareness, a dual-camera system is the gold standard.
Before investing, consider these crucial points in detail:
- Dimensions & Space: A dash cam should be discreet enough not to obstruct your view. The compact design of modern units like this GKU model allows them to be tucked neatly behind the rearview mirror. Consider the screen size as well; a larger screen is easier to operate, but a smaller one is less distracting.
- Capacity/Performance: Video resolution is paramount. 4K offers the best clarity for capturing critical details like license plates, especially at a distance or in motion. Also, look at the field of view (FOV)—a wider angle (150-170°) captures more of the scene. Finally, ensure it supports large-capacity microSD cards for ample recording time.
- Materials & Durability: The device will be subject to temperature extremes inside a car. Look for sturdy construction from high-quality plastics that can withstand summer heat and winter cold without warping or failing. The quality of the mounting hardware, be it adhesive or suction, is also critical for a secure, vibration-free fit.
- Ease of Use & Maintenance: A good dash cam should be a ‘set it and forget it’ device. An intuitive interface, whether via a touchscreen or a companion app, is essential for initial setup and for reviewing footage. Maintenance is minimal, primarily involving occasional formatting of the SD card to ensure its longevity and reliable performance.

First Impressions: A Complete Kit That Oozes Quality
Unboxing the GKU 4K Dash Cam Front and Rear Dual GPS 64GB, the first thing we noticed was the reassuring heft and solid feel of the main unit. As one user aptly put it, it feels like a “seriously solid piece of kit.” There’s no flimsy plastic here; it has a density that suggests durability and quality components inside. GKU has clearly thought about the entire user experience, as the box contains everything you need to get started immediately. This isn’t one of those purchases that requires another trip to the store.
Inside, alongside the 4K front camera and 1080p rear camera, we found a generous 64GB microSD card already installed, a long power cable with an integrated USB-A port (a thoughtful touch for charging a phone), an equally long cable for the rear camera, and a full installation kit. This kit includes a plastic trim tool for hiding cables, several adhesive cable clips, and two large electrostatic films. These films are a brilliant inclusion; you apply them to the windscreen first, then stick the camera mount to the film. This provides a rock-solid hold without leaving any sticky residue on your glass if you ever need to reposition or remove the camera. It’s a small detail that shows a deep understanding of user needs, and it set a positive tone for our entire testing process. You can see the full list of included accessories on the product page.
What We Like
- Crisp and clear 4K front video resolution captures license plates effectively.
- Bright, responsive 3.18-inch IPS touchscreen for easy menu navigation.
- Comprehensive package includes a 64GB SD card and full installation kit.
- Fast 5GHz Wi-Fi for quick video transfers to the companion app.
- Excellent build quality feels robust and durable.
What We Didn’t Like
- Rear camera is only 1080p and lacks the clarity of the front unit.
- Parking mode functionality is basic and requires an optional hardwire kit.
A Deep Dive into the GKU D700’s On-Road Performance
A dash cam’s worth is proven on the road, not in the box. Over several weeks of daily driving—through city traffic, on motorways, in bright sunshine, and on rain-lashed nights—we put the GKU 4K Dash Cam Front and Rear Dual GPS 64GB through its paces. We scrutinised its installation process, its core video capabilities, and the usability of its smart features to determine if it truly delivers on its promise of comprehensive vehicle monitoring.
Installation and Setup: Surprisingly Straightforward
For many, the thought of wiring a dual-camera system is daunting, but we found the process to be remarkably user-friendly. GKU provides ample cable length for both the power and the rear camera, making it suitable even for larger vehicles like our RAV4 test car. The inclusion of the trim tool is a game-changer for a clean, professional-looking installation. We were able to neatly tuck both cables behind the headliner and A-pillar trim, running the rear camera cable all the way to the boot door without any visible wires. As one user noted, “With a bit of effort, I managed to feed both the front and rear cables neatly behind the trim using the tool provided.”
The electrostatic films are the standout feature here. Applying the clear film to the glass before the adhesive mount means you can get the positioning perfect without commitment. Once you’re certain, the 3M adhesive pad creates a strong, vibration-free bond. We positioned the main unit discreetly behind the rearview mirror, where its compact 90mm width kept it out of our direct line of sight. The initial setup is equally simple. You can configure all settings—from video resolution and loop recording time to G-sensor sensitivity—either directly on the surprisingly bright and responsive 3.18-inch touchscreen or via the “GKU GO” app. The camera prompts you to format the included 64GB card on first use, ensuring it’s ready to record from the moment you start the engine.
Video Quality and Evidence Capture: The Power of 4K
This is where the GKU 4K Dash Cam Front and Rear Dual GPS 64GB truly shines. The front camera, recording in native 4K (3840x2160P) at 30 FPS, delivers exceptionally clear and detailed footage. During daylight hours, we could easily read license plates of cars several lengths ahead, as well as road signs and other fine details. This level of clarity is precisely what you need for undeniable evidence. The 170° wide-angle lens provides a panoramic view, covering multiple lanes of traffic and the pavement on either side, effectively reducing blind spots.
Night performance is often the Achilles’ heel of lesser dash cams, but the GKU’s combination of a large F1.8 aperture and Wide Dynamic Range (WDR) technology handles low-light conditions with confidence. It does an excellent job of balancing the darkest parts of the scene with the bright glare of streetlights and oncoming headlights. While it’s harder to read plates at night—a challenge for any camera—the footage remains clear, stable, and more than sufficient to establish the sequence of events in an incident. Our findings align with numerous user experiences, with one stating, “The 4K picture quality is SO much better than the old 1080p dash cam it replaced.” The rear camera, at 1080p, is a step down in quality. It’s perfectly adequate for capturing the context of what’s happening behind you, but as some users noted, it can be a bit “blurry” and lacks the detail of the front camera. Still, having that rear perspective is invaluable and a massive upgrade over a front-only system. The combination of front and rear coverage is a feature that really sets it apart for total peace of mind.
Connectivity and Everyday Use: Smart, Seamless, and Simple
Living with the GKU 4K Dash Cam Front and Rear Dual GPS 64GB is a seamless experience. Once installed, it powers on and begins recording automatically when you start the car, operating silently in the background. The core features just work. Loop recording continuously overwrites the oldest files, so you never have to worry about the card filling up. The built-in G-Sensor is crucial; upon detecting a sudden impact or jolt, it automatically locks the current video file in a separate folder, preventing it from being overwritten and securing your evidence.
Where the GKU D700 elevates itself is with its connectivity. The built-in 5GHz Wi-Fi is significantly faster than the older 2.4GHz standard found on many competitors. Connecting our smartphone to the camera’s Wi-Fi network was quick, allowing us to use the GKU GO app to view a live feed, change settings, and download footage directly to our phone. This is incredibly convenient for reviewing an incident on the spot or sharing a clip without needing to remove the microSD card and find a computer. The integrated GPS module automatically embeds your vehicle’s speed and location coordinates into the video file, adding another layer of crucial data for any potential claim. While most of our experience with the app was smooth, it’s worth noting one user reported having to reconfigure the device on every trip, which seems to be an isolated issue but is important to acknowledge.
What Other Users Are Saying
Across the board, the sentiment from other drivers is overwhelmingly positive, reinforcing our own findings. Many users, especially those upgrading from older 1080p models, are “impressed by the quality of the video even on dark days.” The crispness of the 4K front camera is a recurring theme of praise. The comprehensive nature of the package is another major highlight. One happy customer noted, “Everything you need to get up and running is already thought of and included… they even give you a 64gig SD card.”
The build quality is also frequently commended, with comments like “you can feel the quality of the product is not a bad cheap plastic” confirming our initial hands-on impression. However, the feedback isn’t without its critiques, which provides a balanced view. Several users agree with our assessment of the rear camera, stating it’s “a little bit blurry, but it still captures everything you need.” The most significant limitation mentioned is the parking mode. As one user pointed out, “Only one setting for parking mode 24hr recording ON or OFF that all,” which is quite basic and requires the separate purchase of a hardwire kit. This feedback is crucial for potential buyers who prioritize advanced, configurable parking surveillance.
How Does the GKU D700 Compare to the Alternatives?
The dash cam market is crowded, but the GKU 4K Dash Cam Front and Rear Dual GPS 64GB holds its own. To provide context, we’ve compared it to three notable competitors to help you decide which is the perfect fit for your specific needs.
1. REDTIGER F7N Touch 4K Dash Cam Front and Rear

The REDTIGER F7N is a very strong competitor that goes head-to-head with the GKU on many fronts. It also features a 4K front camera, a similar 3.18-inch touchscreen, and 5GHz Wi-Fi. However, REDTIGER includes a few premium features that might sway some buyers. It comes with a larger 128GB SD card out of the box and incorporates voice control, allowing for hands-free operation to lock videos or take photos. If you value these conveniences and want double the initial storage capacity, the REDTIGER F7N is an excellent alternative worth considering.
2. Dynacam 4K+1080P Front and Rear Dash Cam with WiFi

The Dynacam offers a very similar core feature set to the GKU D700: 4K front and 1080p rear recording, built-in Wi-Fi, and an included 64GB SD card. It positions itself as a direct, budget-friendly alternative. Where it differs is primarily in its design and user interface. It lacks the large touchscreen of the GKU, opting for a more compact, screen-less design controlled almost entirely via its companion app. This might appeal to drivers who want the most discreet installation possible, but those who prefer the ability to change settings directly on the device will find the GKU’s touchscreen more practical.
3. GKU 4K Dual Dash Cam Front and Rear
- 🏆【Ultra HD 4K+1080P Front and Rear Dash Cam】- The GKU D600Pro dual dash cam simultaneously captures the road in detail with a front resolution of 4K 2160P and rear resolution of 1080P. With a...
- 📱【Built-in 5 GHz Wi-Fi and GPS】- With a faster 5 GHz WiFi connection to your smartphone (4 times higher transmission speed than normal 2.4 GHz), you will experience a better preview, download...
Interestingly, one of the main alternatives comes from GKU itself. This model offers the same excellent 4K front camera, 5GHz Wi-Fi, and GPS capabilities. The key difference lies in its form factor. It features a much smaller 1.5-inch IPS screen, making the entire unit even more compact and stealthy than the D700. It also has a slightly lower maximum supported memory of 256GB compared to the D700’s 512GB. This alternative is designed for the minimalist who prioritizes a tiny footprint above all else, while still demanding top-tier video quality and connectivity.
The Final Verdict: A Feature-Packed 4K Dash Cam That Delivers Excellent Value
After extensive testing, the GKU 4K Dash Cam Front and Rear Dual GPS 64GB has proven itself to be a formidable player in the mid-range dash cam market. Its greatest strength is undoubtedly the superb 4K video quality from the front camera, which delivers the kind of detail and clarity needed to serve as a reliable witness. This, combined with a robust build, a user-friendly touchscreen interface, and a truly all-in-one package that includes a 64GB card and installation tools, makes for a compelling offering. It successfully lowers the barrier to entry for comprehensive, dual-camera protection.
While the 1080p rear camera is merely adequate and the parking mode is basic without an extra purchase, these are reasonable trade-offs for its price point. For the vast majority of drivers seeking a dependable, high-quality, ‘set-it-and-forget-it’ system for daily driving, this device is an outstanding choice. If you’re ready to equip your vehicle with a silent witness that offers crystal-clear evidence and modern connectivity features, we can confidently recommend this dash cam. You can check the latest price and secure your peace of mind today.
