Rexing Series 4: Review of the 4-Channel Dash Cam
Most drivers buy a dash cam for the front windshield. If you are driving a large SUV, a van, or a car that regularly parks in tight city spots, a single front-facing lens leaves three sides of your vehicle completely blind. The Rexing Series 4 (often listed as the R4) addresses that gap by recording the front, rear, left, and right views simultaneously. It is a 4-channel system designed to capture every angle of a collision, not just the one facing the road.
If you are looking for a unit that handles parking mode, GPS logging, and Wi-Fi app control without requiring a separate hardwire kit for basic operation, this is a strong contender. The official package includes a 128GB memory card and a 78W quick charger, which removes the friction of buying accessories separately. For drivers who want comprehensive coverage without the complexity of a 4K front-only system, the Rexing Series 4 offers a practical balance of resolution and coverage.

What Reviewers Say
Reviews from Amazon and YouTube say this about the Rexing Series 4.
Amazon One reviewer titled their 5-star review "Great Dash Cam with Many Features, Very Reasonably Priced," noting the all-around 1080p resolution and included Wi-Fi/GPS capabilities. Another 5-star review, "More Angles Equals Better Coverage," emphasized the value of capturing multiple sides of the vehicle. The consensus here is that the price point is attractive for the amount of hardware and features included in the box. Confirm details on the current product page.
YouTube Several creators have covered this specific model. One video is titled "RexingUSA R4 4-Channel 1080p WiFi GPS Dash Cam - HONEST Review," while another calls it the "Ultimate 4 Channel Car Camera!" A third review labels it the "Best Dash Cam for All-Around Protection." These titles suggest that video reviewers align with the product's core promise: that 4-channel coverage is the primary selling point for drivers who feel under-protected by single-lens cameras.

Who It’s For
The Rexing Series 4 is built for drivers who view their vehicle as a target in dense urban environments or on busy highways. If you park in garages, close to other cars, or in areas with high foot traffic, the side and rear cameras are not just "nice to have"—they are essential for identifying the other party in a fender bender.
- Urban Commuters: If you park in tight spots, the left and right cameras help prove you weren't at fault in a door ding or side-swipe.
- Rideshare/Taxi Drivers: Capturing the rear and sides can help document passenger behavior or road incidents from multiple angles.
- Fleet Managers: For small fleets, the 4-channel setup reduces the need to investigate "who hit whom" when two company cars are involved.
- Tech-Forward Drivers: If you want to check footage on your phone via Wi-Fi without pulling an SD card, the app integration is a significant convenience. See options
You can find the current bundle options, which often include the hardwire kit for parking mode, by checking the Rexing Series 4 store page.
Who Should Skip
This is not the right tool for everyone. The 4-channel design adds complexity in terms of cabling and screen management that a single front-facing camera does not have. You can see current options.
- Highway-Only Drivers: If you rarely park in tight spaces and mostly drive interstate highways, a front-facing 4K camera (like the Rexing C1 or Rexing F30) will give you sharper detail on license plates at distance.
- Minimalists: Installing four cameras requires routing wires to the sides and rear of the vehicle. If you want a plug-and-play device that sits on the windshield and connects to the OBD port, this is more work than you likely want.
- 4K Enthusiasts: If you insist on 4K resolution for the front view, this unit records at 1080p across all channels. You will trade resolution for coverage.

How to Choose in Five Minutes
If you are on the fence, here is how to decide if the Rexing Series 4 is the right fit:
- Check Your Parking Habits: Do you park in a garage, on the street, or in a lot? If you park in a garage or tight street spot, the side cameras are a major advantage. If you always park in a driveway, a 2-channel (front/rear) system might be sufficient. See options
- Verify the Hardwire Kit: The official package includes a 78W charger and 128GB card. However, for true 24/7 parking mode that doesn't drain your car battery, you need a hardwire kit. The official page mentions the Rexing Smart Hardwire Kit with 360° Motion Detection. Check if your purchase includes this or if you need to add it.
- Resolution vs. Coverage: Decide if 1080p is enough. For identifying a car in a parking lot, 1080p is generally acceptable. For reading a license plate from 50 feet away on the highway, 4K is better. If you need the latter, look at the Rexing V1P Flex X4 or similar 4K models.
- App Comfort: Ensure you are comfortable using the Rexing Connect app. The Wi-Fi feature is a core part of the experience. If you prefer to just plug an SD card into a computer, the app is a bonus, not a requirement.

FAQ
Does the Rexing Series 4 include a hardwire kit? The standard package listed on the official page includes a 128GB memory card and a 78W quick charger. A hardwire kit is often sold separately or as a bundle. If you plan to use parking mode, verify if the Rexing Smart Hardwire Kit is included in your specific offer, as parking mode without a hardwire connection can drain your vehicle's battery.
Can I view the footage on my phone? Yes. The Rexing Series 4 supports Wi-Fi connectivity. You can download clips directly to your smartphone via the Rexing Connect app, which is a significant convenience for sharing evidence with insurance companies.
Is 1080p enough for a dash cam? For a 4-channel system, 1080p is a standard and practical resolution. It allows the system to handle four video streams without excessive storage consumption. If you need higher detail for the front view specifically, you might consider a dual-channel 4K system, but you will lose the side coverage. Confirm details on the current product page.
How much storage do I need? The included 128GB card is a good starting point. With 4 channels recording in 1080p, you will fill up space faster than with a single-channel camera. The loop recording feature will overwrite the oldest footage when full, so 128GB provides a reasonable buffer for most drivers. You can see current options.
Bottom Line
The Rexing Series 4 is a no-nonsense solution for drivers who want to know exactly what happened around their car, not just in front of it. By recording all four sides in 1080p, it removes the guesswork from side-swipes and parking lot incidents. The inclusion of a 128GB card and 78W charger in the box makes it a complete package for most users.
If you drive in a city, park in tight spaces, or simply want the peace of mind that comes with total vehicle coverage, this is a strong choice. It may not have the razor-sharp 4K front view of a dedicated highway camera, but it offers something those cameras cannot: a complete picture of your surroundings.
