Rexing L4 4: 4-Channel Dash Cam Review
You don’t buy a four-channel dash cam because you want to watch your commute on a loop. You buy it because a single front-facing lens leaves you blind to the side-swipe, the rear-end, and the blind-spot fender-bender that make up the bulk of minor collision claims. The Rexing L4 4 is built for drivers who need simultaneous proof from the front, rear, and both sides of the vehicle, not just a clip of what was in front of the hood. It’s a comprehensive coverage system, and it comes pre-loaded with the accessories you’d otherwise have to hunt down separately.
| Best for | Drivers who want full 360-degree video coverage (front, rear, left, right) in a single system |
| Skip if | You only need a basic front-facing lens or are looking for 4K resolution on the primary channel |
| One line | A 1080p 4-channel dash cam that includes a 128GB card and a 78W charger in the box |

What the Official Page Actually Lists
The Rexing L4 4 is positioned as a full-vehicle coverage system. Here are the specific details pulled from the official product listing:
- Resolution: 1080p across all four channels.
- Channels: 4 (Front, Rear, Left, Right).
- Included Accessories: 128GB memory card and a 78W quick charger.
- Key Features: Ultra-wide angle, Wi-Fi connectivity, Night Vision, GPS, App Control, Loop Recording, and a Collision Sensor.
While the listing confirms the 1080p resolution and the specific bundle contents (card + charger), it does not specify the exact field-of-view degrees for each lens or the maximum supported storage capacity beyond the included 128GB card. If you plan to push the storage higher, verify the maximum supported micro-SD card size on the brand’s support page before purchasing a larger drive.
Who It’s For
This system is designed for drivers who view their vehicle as a liability to be managed, not just a mode of transport. If you drive in dense urban traffic, navigate narrow parking lots, or frequently park in areas where you can’t see the rear bumper, the L4 4 is a practical tool.
- Fleet and Rideshare Drivers: If you need to prove exactly which lane you were in and what was behind you during a dispute, four synchronized feeds are significantly more persuasive than a single front view.
- Drivers of Larger Vehicles: SUVs and trucks have larger blind spots. The side channels on the L4 4 help document close-quarters maneuvers that a standard front cam misses.
- Those Who Want a "Ready-to-Go" Setup: Because the 128GB card and 78W charger are included, you avoid the common frustration of buying a dash cam only to realize you need a separate high-speed card and a higher-wattage charger to run multiple lenses effectively.
Who Should Skip
Not every driver needs four lenses. If your primary concern is recording the road ahead for insurance purposes, a four-channel system may be overkill and more complex to install.
- Front-Facing Only Users: If you just want to catch the car that rear-ends you or the accident ahead of you, a dual-lens or single-lens system is simpler and cheaper.
- 4K Enthusiasts: The L4 4 records at 1080p on all channels. If you require 4K resolution for the front channel to read license plates from a distance, this model does not meet that spec.
- DIY-averse Installers: While the system is designed for ease of use, a four-channel setup involves more cabling and mounting points than a single front cam. If you are not comfortable routing wires to the rear and sides of the vehicle, you may want to stick to a simpler configuration.

How to Choose in Five Minutes
- Check the Bundle: Confirm that the 128GB card and 78W charger are still included in the current listing. This saves you the cost of separate accessories.
- Verify Parking Mode Requirements: If you plan to use parking surveillance, note that this typically requires a hardwire kit connected to an active fuse or a cigarette plug that charges while the car is off. The standard power cable may not support 24/7 parking mode without additional hardware.
- Review App Compatibility: The L4 4 uses Wi-Fi and app control. Ensure the app is compatible with your phone’s operating system before purchasing.
- Consider the Resolution: 1080p is sufficient for most traffic and incident documentation, but understand that it is not 4K. If you need extreme detail, look elsewhere.
- Check the Warranty: Confirm the current warranty terms for the L4 4 on the brand’s site, as policies can change.
FAQ
Is the 128GB memory card included with the Rexing L4 4? Yes, the official product listing states that the 128GB memory card is included in the box along with the 78W quick charger.
Does the Rexing L4 4 support 4K recording? No, the L4 4 records in 1080p resolution on all four channels. It is designed for comprehensive coverage rather than ultra-high-resolution front-facing video.
Can I use parking mode without a hardwire kit? Parking mode generally requires a power source that remains active when the vehicle is off, such as a hardwire kit connected to an active fuse or a specific cigarette plug setup. The standard power cable may not support continuous parking surveillance.
What is the benefit of four channels over two? Four channels provide simultaneous coverage of the front, rear, left, and right sides of the vehicle. This is particularly useful for documenting side-swipes, blind-spot incidents, and rear-end collisions that a front-and-rear dual cam might miss.
If the FAQ answered your main objections and you want current models or trial terms, see brand options.
Bottom Line
The Rexing L4 4 is a no-nonsense, comprehensive dash cam system for drivers who want to eliminate blind spots in their incident documentation. It doesn’t chase 4K specs or gimmicks; it focuses on giving you four 1080p feeds, a pre-installed 128GB card, and a high-wattage charger in one box. If you need to prove what happened on all sides of your car, this is a practical, ready-to-use option.
