Rexing Rear 4K Review: The C2 Pro Dual Dash Cam
You are not buying a camera to make your car look cool. You are buying it because the insurance adjuster needs proof of who hit you, or because you want to know if the delivery driver actually left the package in the rain. The Rexing Rear 4K (sold as the Rexing C2 Pro 4K Dual Dash Cam) exists to solve the "he said, she said" problem on the highway. It is a dual-channel system that records the road ahead and the traffic behind you simultaneously, ensuring that if a fender bender happens in your blind spot, you have the footage to prove your lane position.
The defining feature here is the resolution. While many entry-level cams stop at 1080p, this unit pushes 4K video to the front lens, which is critical for reading license plates in low light. The rear camera handles the tailgate view, creating a complete record of your driving day. If you are tired of guessing what happened in a near-miss, this is the hardware that stops the guessing.

What the Official Page Actually Lists
The Rexing C2 Pro 4K Dual Dash Cam is positioned as a premium dual-channel solution. The official product page highlights specific hardware choices that differentiate it from budget models.
- Resolution: The front camera records in 4K. The rear camera provides complementary coverage.
- Field of View: Both lenses offer 170° Ultra-Wide-Angle Coverage. This wide angle is designed to reduce blind spots and capture more of the road, including adjacent lanes.
- Lens Material: The unit uses wide-angle glass lenses. Glass is generally preferred over plastic in high-end dash cams because it is less prone to scratching and provides better optical clarity in harsh lighting conditions.
- Power & Safety: The system is designed to work with a Rexing Smart Hardwire Kit. This kit enables parking mode features, such as motion detection and impact recording while the vehicle is off.
- Connectivity: The system supports Wi-Fi, allowing you to transfer footage or adjust settings via a smartphone app (Rexing Connect).
Note: Specific battery capacity, storage card compatibility limits, and exact low-light sensor details are not explicitly detailed in the provided research snippets. Verify these specifications on the brand page before purchase if you drive in extreme climates or have specific storage needs.
Who It's For
This device is for the driver who views their vehicle as a liability to be managed, not just a mode of transport.
- Highway Commuters: If you spend hours on multi-lane highways, the 170° wide-angle coverage is essential. It captures vehicles in adjacent lanes, which is vital for proving you were not drifting during a collision.
- Ride-Share or Delivery Drivers: If you use your car for work, you need continuous, high-quality evidence. The 4K resolution helps identify other vehicles and road signs clearly, which can be the difference between a successful claim and a denied one.
- Tech-Savvy Owners: If you are comfortable using a smartphone app to manage your camera, the Wi-Fi connectivity of the Rexing C2 Pro makes transferring video to your phone quick and easy, without needing a laptop.
Who Should Skip
This is not the right tool if your needs are basic or your installation constraints are strict.
- Front-Only Users: If you only care about what happens in front of your bumper, you are paying for a rear camera you may never use. A single-channel 4K cam might be a better value.
- Those Without Hardwire Access: The parking mode features, which are a major selling point, require a hardwire kit to function correctly. If you cannot access the fuse box or do not want to run wires, the camera will only record while the engine is on.
- Battery Anxiety Drivers: One user review noted that parking mode can drain the car battery if not connected to an active fuse or a charging cigarette plug. If you leave your car parked for weeks at a time, you need to understand the power implications of enabling these features.

If the criteria already match how you live in the space, see current options before you keep comparing.
- Check Your Insurance: Does your policy require dash cam footage? If so, 4K is the safest bet for license plate legibility.
- Inspect Your Dashboard: Ensure you have a clear view of the rear windshield for the rear camera. The 170° angle helps, but physical obstructions (like a sunshade) will ruin the footage.
- Plan for Power: Decide if you will use a cigarette lighter plug (simple, but no parking mode) or a hardwire kit (complex, but enables parking surveillance). The Rexing Smart Hardwire Kit with 360° Motion Detection is the recommended companion for full functionality.
- Verify App Compatibility: Ensure your phone supports the Rexing Connect app. The system relies on this for easy video retrieval.
- Review the Lens: Confirm the unit has glass lenses, as listed in the specs. This is a durability marker that sets it apart from cheaper plastic-lens alternatives.
Frequently Asked Questions
Does the Rexing Rear 4K work in the dark? The unit features 4K resolution on the front camera and wide-angle glass lenses, which are designed to handle low-light conditions better than standard plastic lenses. However, for the best night performance, ensure the camera is clean and positioned correctly. For specific night-vision sensor details, check the technical specifications on the official product page.
Can I use it without a hardwire kit? Yes. You can power it via the cigarette lighter socket. However, you will not have access to parking mode features like motion detection or impact recording while the car is off. The Rexing Smart Hardwire Kit is required to enable these safety features.
What happens if the SD card gets full? Dash cams like the Rexing C2 Pro typically use loop recording. When the card is full, it overwrites the oldest footage. This ensures you always have the most recent video available.
Is the rear camera included in the box? Yes, the "Dual Dash Cam" designation means it includes both the front and rear units. The rear camera is designed to be mounted on the rear windshield or interior, providing a view of the tailgate and traffic behind you.
Bottom Line
The Rexing Rear 4K is a serious piece of automotive security. It is not a toy; it is a recording device that provides 4K clarity and wide-angle coverage for both the front and rear of your vehicle. If you want the best chance of proving your side of a traffic incident, the combination of 4K resolution and 170° wide-angle glass lenses makes this a strong choice. Just be prepared to either hardwire it for parking mode or accept that it will only record while you are driving.
