Rexing R4 4 Channel Dash Cam Review: All-Around 1080p Coverage for Fleet and Family Cars

If you have ever tried to argue a fender-bender claim with a single front-facing video, you know the gap: the car behind you, the one in the passenger lane, and the one in the back seat all matter. The Rexing R4 4 Channel Dash Cam is built to close that gap by capturing 1080p video from four angles at once—front, rear, and both interior sides—so the full story is on one SD card instead of scattered clips. It is not a 4K flagship; it is a practical, all-around recorder for drivers who want coverage without juggling three separate cameras.

For most drivers, the value is in the coverage, not the resolution. If you need 4K license-plate clarity at 200 feet, this is not the SKU to buy. If you need a complete record of what happened around your car, the Rexing R4 4 Channel Dash Cam is a strong fit.

Quick Answer


Best for	Drivers who want 360°-style coverage (front, rear, and both interior sides) in one system, with Wi-Fi and optional GPS logging.
Skip if	You need 4K front resolution, or you only need a single front channel and want the simplest possible install.
One line	A four-channel 1080p dash cam system that records the whole car environment at once, with Wi-Fi transfer and GPS.

The official Rexing product page for the Rexing R4 4 Channel Dash Cam describes the system as delivering all-around 1080p resolution with built-in Wi-Fi and optional GPS. Here is what the official listing states:

Rexing positions the R4 as a multi-channel system for drivers who want comprehensive vehicle coverage rather than a single front-facing lens. Because the official page does not publish specific sensor model numbers, exact field-of-view angles, or battery backup specs in the fetched content, verify those details on the Rexing R4 product page before purchase if they matter to your setup.

What Reviewers Say

Reviews from Amazon and YouTube say this about the Rexing R4 4 Channel Dash Cam.

Amazon — One Amazon reviewer titled their five-star review "Solid, Easy to Install, and Packed with Great Features," and another called it "Great picture quality, easy install." A third reviewer wrote "Great Coverage, Clear Video, and Easy to Use." The recurring theme across these reviews is that the four-channel setup is straightforward to install and the video quality holds up well for the price point, which is exactly the job this SKU is designed to do: give you usable, clear footage from every angle without a complicated wiring project. You can see current options.

YouTube — A YouTube review titled "RexingUSA R4 4-Channel 1080p WiFi GPS Dash Cam - HONEST Review" walks through the system, and a second video calls it the "Ultimate 4 Channel Car Camera." In a third video, the reviewer notes that Rexing recommends a CPL filter designed specifically for this camera to reduce glare from headlights and streetlights—a detail that signals the brand is thinking about real-world night driving, not just spec sheets. For drivers who care about night visibility across all four channels, that accessory recommendation is a useful data point. Confirm details on the current product page.

Who It's for

The Rexing R4 4 Channel Dash Cam makes the most sense for drivers whose priority is complete documentation rather than maximum front-lens resolution.

Fleet and ride-share drivers who need to document incidents from every angle, including passenger-side interactions.
Parents of new drivers who want interior footage to review driving habits and road behavior.
Drivers in high-theft or high-accident areas who want rear and side coverage to capture hit-and-run details.
Fleet managers who want a single system that covers the whole vehicle environment without mounting three separate cameras. See options

If you fall into one of those categories, the four-channel 1080p coverage is the core reason to choose this model over a single-lens dash cam.

Who Should Skip

The R4 is not the right pick for everyone, and being honest about that saves you money. You can see current options.

Drivers who only need front-channel recording. If a single 1080p or 4K front camera covers your needs, a simpler, cheaper unit will do the job. The four-channel system adds cost and a slightly more involved install.
Drivers who need 4K front resolution. The R4 records at 1080p across channels. If you specifically need 4K for license-plate readability at distance, look at Rexing's higher-resolution models or other brands in that tier.
Drivers who want a plug-and-play, no-wiring setup. The R4 is a hardwired multi-channel system. If you want a battery-powered, stick-on single camera, this is more setup than you need.

If any of those apply, a simpler dash cam will serve you better, and you can compare options in our dash cam buying guide before deciding. You can see current options.

How to Choose in Five Minutes

You do not need to spend an hour comparing specs to decide if the Rexing R4 4 Channel Dash Cam is right for you. Ask yourself these five questions:

Do I need more than one camera angle? If yes, the R4's four-channel design saves you from buying and mounting separate units. See options
Is 1080p enough resolution for my use case? For most insurance claims and incident documentation, 1080p is sufficient. If you need 4K, look elsewhere. See options
Do I want GPS logging? The R4 supports an optional GPS module, which stamps time and location onto your footage—useful for fleet tracking or legal documentation. See options
Am I comfortable with a wired install? The R4 is designed to be hardwired to your vehicle's power. If you want a temporary, battery-powered setup, this is not the model. See options
Do I want Wi-Fi transfer? The built-in Wi-Fi lets you pull clips to your phone without removing the SD card, which is a small but real convenience. See options

If you answered "yes" to at least three of those, the Rexing R4 4 Channel Dash Cam is worth a closer look. You can also check our guide to choosing a multi-channel dash cam for a deeper comparison of four-channel systems.

FAQ

What channels does the Rexing R4 4 Channel Dash Cam record? The R4 records four channels simultaneously: front, rear, and two interior/side angles, all at 1080p resolution. This gives you a complete record of the vehicle environment in a single file set.

Does the Rexing R4 have GPS? Yes, the R4 supports an optional GPS module. When installed, it logs speed, location, and time alongside your video, which is useful for fleet tracking or adding context to insurance claims.

Is the Rexing R4 a 4K dash cam? No. The R4 records at 1080p across all four channels. If you need 4K front resolution, you will want a different model. The R4's strength is its four-channel coverage, not peak front-lens resolution.

How do I transfer video from the Rexing R4? The R4 has built-in Wi-Fi, which lets you connect to your phone and download clips directly. You can also remove the SD card for manual transfer. For day-to-day use, the Wi-Fi option is the faster path.

Is the Rexing R4 hard to install? It is a wired, multi-channel system, so the install is more involved than a single stick-on camera. You will need to route power and connect the four channels. Most reviewers describe the process as manageable for someone comfortable with basic car wiring. If you are not, a professional install is a reasonable option.

If the FAQ answered your main objections and you want current models or trial terms, see brand options.

Bottom Line

The Rexing R4 4 Channel Dash Cam is not the flashiest dash cam on the market, and it will not win a 4K resolution comparison. But for the specific job it is built to do—recording what happens in front of, behind, and inside your car at the same time—it is a practical, well-reviewed choice. The four-channel 1080p coverage, optional GPS, and Wi-Fi transfer make it a strong fit for fleet drivers, parents, and anyone who wants a complete record of the road without buying three separate cameras.

If you want all-around coverage at 1080p, the Rexing R4 4 Channel Dash Cam is worth your time. If you need 4K or a single-channel simplicity, look at other options in our dash cam comparison guide.
