Rexing RH2 Dual Dash Cam Review: 4K Front, 1080p Rear, Wi-Fi, and Optional GPS

You do not buy a dual dash cam to get a nicer view of the highway. You buy it so that the next time someone rear-ends you at a red light or a delivery van clips your bumper in a parking lot, you have a timestamped, high-resolution file that is actually admissible and legible. The Rexing RH2 is built for that exact job: a 4K front lens paired with a 1080p rear lens, Wi-Fi transfer to your phone, and an optional GPS module for speed and location data. It is not a smart-home gadget or a lifestyle accessory. It is a piece of automotive insurance that sits behind your rearview mirror and records whether you like it or not.

If you are weighing whether this specific unit fits your vehicle and your driving patterns, the Rexing RH2 product page is the best place to confirm current bundle options and GPS availability before you commit.

What the official page actually lists

The official Rexing product page for the Rexing RH2 describes it as a dual dash cam with the following headline specs:

Rexing states on its product pages that it designs, tests, and manufactures its devices to guarantee reliability and longevity. The RH2 sits in the same product family as the Rexing F30 4K+1080p Dual Dash Cam and the Rexing C1 2K Front Dash Cam, which share the brand's focus on automotive-grade recording hardware. For the RH2 specifically, verify on the official Rexing USA product page whether the GPS module is included in your regional bundle or sold separately, and confirm the exact screen size and parking-mode power requirements, as those details can vary by market.

What reviewers say

Reviews from YouTube say this about the Rexing RH2.

On YouTube, one walkthrough of the RH2 highlights that you can "seamlessly connect to the Rexing app via Wi-Fi for easy management, viewing, and playback of recordings on your iOS or Android devices." That is the core of what makes a dual-channel unit practical: you are not digging through a micro-SD card in a glove box after an incident. You pull up the app, find the clip, and share it. For a driver who wants to check a parking-lot scuff within minutes of it happening, that workflow is the whole point.

A second YouTube review, titled "RexingUSA RH2-4 Quad-Channel Dash Cam: Full Coverage for Your Car! | Review," frames the RH2 family as a full-coverage solution. The "full coverage" framing matters here: the RH2's dual-channel design (4K front, 1080p rear) is aimed at drivers who want to close the gap between "I can see what hit me from the front" and "I can also see what happened behind me." If your daily driving involves tight parking structures, school-zone traffic, or highway merging, that rear 1080p channel is doing real work, not just filling a spec-sheet line. You can see current options.

Who it's for

The Rexing RH2 makes sense for a specific set of drivers. If you match more than two of these, the unit is likely a good fit:

• You drive in urban or suburban areas where fender-benders and parking-lot incidents are a realistic weekly risk, and you want both front and rear video without running two separate cameras.
• You prefer reviewing footage on your phone rather than pulling out a laptop. The Wi-Fi connection to the Rexing app means you can watch, download, and share clips from the driver's seat.
• You want the option to add GPS data (speed, location, timestamp) to your recordings, which can matter in insurance claims and police reports. The optional GPS module for the Rexing RH2 is the upgrade path here.
• You are comfortable with a small built-in screen for quick playback and do not need a full smart-mirror display.

If you already own a Rexing Smart Hardwire Kit with 360° Motion Detection, pairing it with the RH2 gives you parking-mode recording with motion and impact triggers, which extends the camera's usefulness beyond just driving hours.

Who should skip

The Rexing RH2 is not the right tool for everyone. Consider looking elsewhere if:

• You only need a front-facing camera. If rear coverage is not a priority for your driving environment, a single-lens unit like the Rexing C1 2K Front Dash Cam with Wi-Fi will be simpler and less expensive.
• You want a supercapacitor-based power system that does not require a hardwire kit for parking mode. Some Rexing models in the lineup, like the C1, explicitly list a supercapacitor for extreme-temperature reliability. Confirm on the Rexing RH2 product page how the RH2 handles parking-mode power in your region, because a battery-based parking mode without a hardwire kit can drain your car's battery.
• You want a triple-channel or quad-channel setup (front, rear, and cabin). The RH2 is a dual-channel unit. If you need cabin coverage, the Rexing V1P Flex X4 4K WiFi Dual Dash Cam or the RH2-4 quad-channel variant mentioned in community reviews are the directions to explore.
• You prefer a mirror-style display that replaces your rearview mirror. The RH2 uses a conventional small screen, not a smart-mirror form factor.

How to choose in five minutes

You do not need a spreadsheet to decide if the Rexing RH2 is right for you. Run through this five-minute check:

1. Count your risk vectors. If you park in a garage, drive school zones, or merge on highways, you want rear coverage. That alone justifies the dual-channel design over a front-only unit. See options
2. Check your power situation. Do you have a hardwire kit or a fused cigarette-lighter adapter? If not, and you want parking mode, budget for the Rexing Smart Hardwire Kit and confirm the RH2's parking-mode power draw on the official product page.
3. Decide on GPS. If you file insurance claims regularly or drive in areas with variable speed limits, the optional GPS module adds speed and location stamps that make your footage more credible. If not, the base unit is sufficient. See options
4. Confirm the bundle. The Rexing RH2 may ship with or without the GPS module and hardwire kit depending on your region. Read the "what's in the box" section before you click buy.
5. Check the app. Make sure the Rexing app is available on your phone's OS and that the Wi-Fi pairing process is straightforward. The app is how you will review 90% of your footage.

If all five checks line up, the Rexing RH2 is a no-fuss dual dash cam that does its job. If two or more checks fail, a different configuration or a different product in the Rexing lineup may serve you better.

FAQ

What is the difference between the Rexing RH2 and the Rexing F30? Both are dual-channel dash cams with 4K front and 1080p rear recording. The specific feature differences (screen size, GPS availability, parking-mode power source) vary by model and region. Check the Rexing F30 4K+1080p Dual Dash Cam and the Rexing RH2 product pages side by side to compare the exact specs in your market.

Does the Rexing RH2 come with GPS? The GPS module is listed as optional on the official product page. Whether it is included in your regional bundle or sold separately depends on where you are buying. Confirm the included accessories on the official Rexing USA page before ordering.

Can I view recordings on my phone? Yes. The Rexing RH2 connects to the Rexing app over Wi-Fi, allowing you to view, manage, and play back recordings on iOS or Android devices. This is one of the features highlighted in community reviews of the unit.

Does the Rexing RH2 support parking mode? Parking mode is available, but it typically requires a hardwire kit to draw power from the vehicle's battery without draining it. The Rexing Smart Hardwire Kit with 360° Motion Detection is the recommended accessory. Confirm the exact parking-mode requirements and power draw for the RH2 on the product page.

What is the front camera resolution on the Rexing RH2? The front camera records in 4K, and the rear camera records in 1080p, as listed on the official product page.

Bottom line

The Rexing RH2 is not trying to be the smartest dash cam on the shelf. It is a 4K-front, 1080p-rear, Wi-Fi-connected dual-channel unit with an optional GPS module, and it does that job clearly. If you want front and rear coverage without a mirror-style display, phone-based clip review, and the option to stamp your footage with speed and location, the Rexing RH2 is a straightforward, well-scoped choice. It sits in the same product family as the Rexing C1 and the Rexing F30, all of which reflect Rexing's stated commitment to designing and testing devices for reliability and longevity in automotive environments.

Confirm your regional bundle contents, parking-mode power requirements, and GPS availability on the official Rexing USA product page before you buy, and you will know within a few minutes whether this is the right dual dash cam for your car.
