Rexing R4 Rd 4 Channel Dash Cam Review
If you park your car in a tight urban garage, a busy office lot, or a residential street where fender benders happen overnight, a single front-facing camera leaves you blind to the sides and rear. The Rexing R4 Rd 4 Channel Dash Cam is built to close that gap. It uses four 1080p lenses to cover the front, rear, and both sides of your vehicle, creating a continuous visual record when you are driving and when you are parked. Unlike systems that require you to buy separate hardwire kits or external motion sensors, this unit has a built-in 360° parking monitor. That means it is designed to start recording automatically if it detects movement around your car, without extra accessories cluttering your dashboard.
Quick Answer

What the Official Page Lists
The official product page for the Rexing R4 Rd 4 Channel Dash Cam highlights specific features that distinguish it from standard dual-channel units. Here are the key specifications and claims listed by Rexing:
- Resolution: All-around 1080p recording (four channels).
- Parking Monitor: Built-in 360° motion detection with an integrated sensor (no extra accessories needed for 24/7 protection).
- Connectivity: Wi-Fi and GPS built-in.
- GPS Data: Logs route, speed, and location, viewable via the Rexing GPS Player.
- Power & Recording: Type-C power port and continuous loop recording.
- Night Vision: IR (Infrared) night vision capability.
Note: While the page confirms the inclusion of GPS and Wi-Fi, it does not specify the exact storage capacity included in the box or the specific battery/supercapacitor type used for parking mode power. You should verify these details on the official product page before purchasing, especially if you plan to use the 24/7 parking mode extensively.
Who It’s For
This camera is designed for drivers who feel that a standard front dash cam is insufficient for their daily parking situations.
- Urban commuters: If you park in cities where sideswipes or hit-and-runs are common, the side and rear cameras provide the evidence a front-only camera cannot.
- Fleet or ride-share drivers: The built-in GPS logs speed and location, which is useful for verifying routes and incident contexts.
- Tech-forward users: If you prefer a system that works out of the box for parking mode without hunting for a separate hardwire kit, the integrated motion sensor is a significant convenience.
Who Should Skip
Not every driver needs four cameras. Consider skipping this model if your needs are simpler.
- Highway-only drivers: If you rarely park in vulnerable spots and mostly drive on highways, a high-resolution front-facing camera like the Rexing C1 2K Front Dash Cam may offer better image quality for the same price.
- DIY-averse users: While the motion sensor is built-in, 24/7 parking mode still requires a power source that stays active when the car is off (typically a hardwired connection to the fuse box). If you cannot or do not want to hardwire your dash cam, the parking feature will not work as intended.
- Those seeking 4K resolution: This model records at 1080p on all channels. If you prioritize ultra-high resolution for the front view over 360-degree coverage, you might look at the Rexing V1P Flex X4 4K WiFi Dual Dash Cam instead, though it lacks the 4-channel 360-degree parking coverage.

How to Choose in Five Minutes
If you are deciding between this unit and other options, focus on these three questions:
- Do you need side coverage? If you park in tight spaces or high-risk areas, the 4-channel setup is the primary value. If you only need front and rear, a dual-channel cam is cheaper and often higher resolution.
- Can you hardwire it? The built-in parking monitor is a major feature, but it requires constant power. Check if you are comfortable accessing your fuse box or if you will hire a professional. Without hardwiring, you are limited to driving-only recording.
- Do you use GPS data? If you drive for a living or want to log your routes, the built-in GPS is useful. If you just need video for insurance, a simpler cam without GPS may suffice.
FAQ
Does the Rexing R4 Rd 4 Channel Dash Cam require a separate hardwire kit for parking mode? No, the unit features a built-in 360° motion parking monitor with an integrated sensor. However, to keep the camera powered while the car is off, you will still need to connect it to a constant power source, usually via a hardwire connection to your vehicle’s fuse box. The "built-in" aspect refers to the motion detection hardware, not the power supply.
What resolution do the four cameras record at? According to the official product page, all four channels record at 1080p. This provides full HD coverage on the front, rear, and both sides of the vehicle.
Can I view the GPS data on my phone? Yes, the camera includes Wi-Fi and GPS. You can view the video via the app, and the GPS data (speed, location, route) can be viewed using the Rexing GPS Player.
Is there a warranty? Rexing typically offers a warranty on their products, and customer reviews on the official site mention receiving replacements under warranty. However, warranty terms can change, so you should verify the current warranty period and coverage details directly on the Rexing support page before finalizing your purchase.
Bottom Line
The Rexing R4 Rd 4 Channel Dash Cam is a specialized tool for drivers who need comprehensive visual coverage. It solves the blind spots of traditional dash cams by adding side and rear views, and it simplifies the parking mode setup with an integrated motion sensor. If you park in high-risk areas and are willing to hardwire the unit, this is a strong choice. If you only need a front-facing camera or prefer a plug-and-play solution without hardwiring, you may find a simpler, single-channel model more suitable.
