Rexing F30 Review: The 4K Rearview Mirror Dash Cam for Drivers Who Want One Clean Install
If you have tried to mount a traditional boxy dash cam and ended up with a cable snake across your windshield or a blind spot in your rearview mirror, the Rexing F30 is the fix. It replaces your standard mirror with a 12-inch display that records 4K video to the front, 1080p to the rear, and streams live footage to your phone over Wi-Fi. You get a clean, unobstructed view of the road behind you while the camera handles the evidence-gathering job.
This is not a budget "set it and forget it" stick-on cam. It is a full-system upgrade for drivers who want high-resolution footage, GPS data logging, and a mirror that actually looks like part of the car. If you are looking for a reliable way to capture insurance-ready video without cluttering your dashboard, the Rexing F30 is a strong contender in the mirror-cam category.

What Reviewers Say
Reviews from YouTube say this about the Rexing F30.
On YouTube, a creator documented an open-box review and installation of the 4K SMART 12" Rexing Rearview Mirror Dash Cam on a Ford F-150. The video highlights the ease of swapping the mirror and the clarity of the 4K front feed. This aligns with the core value proposition of the F30: it simplifies the install by using the existing mirror mount, making it a practical choice for truck and SUV owners who want a robust, high-res system without complex wiring.
Another YouTube review covers the Rexing V1 Gen3, a different model in the lineup, but it provides useful context on the brand’s general build quality and app functionality, which is consistent across their smart dash cam ecosystem.
A third YouTube video features a five-star review of the Rexing V1, praising the 1080p 170-degree wide-angle capture. While this is a different SKU, it reinforces that Rexing’s cameras are well-regarded for their wide field of view and reliable recording, traits that carry over to the F30’s mirror-cam design.
Who It’s For
The Rexing F30 is a specific tool for a specific driver. It is not a universal solution for every vehicle, but it fits a clear profile.
- Drivers of trucks and SUVs: The 12-inch mirror size is substantial. It works best in vehicles with a larger windshield and a standard mirror mount, such as the Ford F-150 or similar pickups.
- Tech-comfortable users: You will need to pair the device with a smartphone app to view footage, manage settings, and download clips. If you are not comfortable with Bluetooth/Wi-Fi pairing, this may be a hurdle.
- Safety-conscious commuters: If you drive in high-traffic urban areas or on highways where incidents are common, the 4K front and 1080p rear coverage provides comprehensive evidence.
- Cleanliness-focused owners: If you hate the look of a black box on your windshield or a dangling cable, the mirror integration offers the cleanest possible aesthetic. See options
Who Should Skip
This is not the right dash cam for everyone. If any of the following apply, look elsewhere. Confirm details on the current product page.
- Drivers of compact cars: The 12-inch mirror may be too large for smaller windshields, potentially obstructing your view or looking disproportionate.
- Minimalists: If you want a tiny, invisible camera that you never think about, a standard 1080p box cam is a better fit.
- No-phone users: The F30 relies heavily on the app for file management. If you do not want to use your phone to interact with your car’s camera, this system will feel clunky.
- Budget shoppers: Mirror dash cams are a premium category. If you are looking for the cheapest possible option, the F30 will likely be overkill and over budget. See options

How to Choose in Five Minutes
If the criteria already match how you live in the space, see current options before you keep comparing.
If you are on the fence, here is how to decide if the Rexing F30 is the right move for you.
- Check your mirror mount: Ensure your vehicle uses a standard single-post mirror mount. If your car has a unique or dual-post mount, you may need an adapter, which can complicate the install. See options
- Verify your phone compatibility: Confirm the Rexing app is available for your iOS or Android version. The app is your primary interface for the camera.
- Assess your storage needs: 4K recording eats through memory cards quickly. Plan to buy a high-endurance, high-capacity microSD card (128GB or 256GB) to ensure you have enough footage for a full day of driving. See options
- Consider the rear camera: The F30 is a dual-channel system. If you only care about the front, a single-channel mirror cam might be cheaper. But if you want rear coverage for hit-and-runs, the F30’s integrated rear cam is a major plus. See options
- Read the warranty: Check the current warranty period on the official site. Dash cams are exposed to heat and vibration, so a solid warranty is important. See options
FAQ
Is the Rexing F30 hard to install? No. It is designed to replace your existing rearview mirror. You typically just unclip your old mirror, attach the F30, and route the power cable to your 12V source. The hardest part is usually hiding the cable along the A-pillar.
Does the Rexing F30 have parking mode? Yes, most Rexing mirror cams include parking mode. However, the specific type (24/7 battery drain vs. hardwired low-voltage cut-off) depends on the power source. You will likely need a hardwire kit for true 24/7 parking surveillance.
Can I use the Rexing F30 without the app? You can view footage on the built-in screen, but the app provides a much better experience for downloading clips, checking GPS data, and adjusting settings. For full functionality, the app is essential.
What is the warranty on the Rexing F30? Rexing typically offers a standard warranty on their dash cams. For the most current terms, verify the warranty details on the official Rexing product page, as policies can change.
Is the 4K resolution on the Rexing F30 overkill? For insurance claims, 4K is excellent. It captures license plates and facial details clearly. If you only need general incident recording, 1080p is sufficient, but the F30’s 4K front cam is a significant advantage in high-resolution evidence.
If the FAQ answered your main objections and you want current models or trial terms, see brand options.
Bottom Line
The Rexing F30 is a premium, all-in-one solution for drivers who want a clean, high-resolution dash cam system. It replaces your mirror with a 12-inch display, records in 4K to the front and 1080p to the rear, and connects to your phone for easy file management. It is not the cheapest option, and it is not for every car, but for drivers of trucks and SUVs who value a tidy install and high-quality footage, it is a top-tier choice.
