10 Best Dash Cams Rearview Mirrors of 2026

If you’re a rideshare driver, limo operator, or parent needing peace of mind about what happens inside your vehicle, the Rexing Cabin View Camera delivers game-changing surveillance with surgical precision. Designed as a modular add-on for the V55 dash cam, this compact unit packs a 170° ultra-wide-angle lens and infrared night vision, ensuring every corner of your cabin is captured—even in pitch-black conditions. Its seamless integration transforms your front-facing recorder into a dual-purpose guardian, solving the critical blind spot of interior activity without requiring additional wiring or power sources.

In real-world testing, the cabin camera proves indispensable during nighttime rides or unattended stops. The infrared sensors activate instantly in low light, delivering crisp, detailed footage that clearly captures facial features, clothing, and movements—far beyond the grainy output of standard interior cams. Whether monitoring a sleeping child in the backseat or documenting passenger behavior, the wide field of view eliminates blind zones. However, it’s worth noting that without the V55 host unit, this camera is non-functional, making it a powerful but dependent accessory rather than a standalone solution.

Compared to basic interior dash cams, the Rexing Cabin View raises the bar by offering true modular synergy—a rarity in the aftermarket space. While competitors often require separate apps or power draws, this unit syncs effortlessly with the V55’s existing interface and storage. It’s ideal for professionals who need reliable, discreet monitoring without cluttering their dash. Against the standalone Rexing V1P Flex X4, it lacks independence, but for those already invested in the V55 ecosystem, it offers unmatched value and functionality in one streamlined package.

The Rexing V3 Dual Camera stands out as a rare find for budget-conscious drivers who refuse to compromise on interior security. This open-box gem delivers dual-channel Full HD 1080p recording, capturing both the road ahead and the cabin’s interior with clarity that belies its discounted status. With infrared night vision, supercapacitor resilience in extreme temperatures, and built-in GPS, it tackles two major pain points: unreliable power sources and poor low-light performance—making it a stealth powerhouse for Uber or delivery drivers.

During daily commutes and overnight parkings, the V3 consistently delivered sharp, synchronized footage from both lenses. The 2.7” LCD screen is responsive, and Wi-Fi pairing with the mobile app allows quick video exports—ideal for sharing incident clips. Parking mode activates reliably when hardwired, though the supercapacitor ensures safe shutdown during voltage drops. That said, some users report confusion during setup due to unclear on-screen prompts, and the lack of a rearview mirror mounting option means it sits awkwardly on the dash, obstructing sightlines slightly.

When stacked against the premium REXING CPDuo Pro, the V3 trades screen size and CarPlay integration for raw functional value. It doesn’t mirror your phone or replace your rearview mirror—but it does deliver reliable dual recording at a fraction of the cost. For drivers prioritizing interior accountability over luxury features, this open-box unit offers exceptional bang for the buck. While not brand-new, its condition and performance rival that of factory-fresh models, making it one of the smartest entries in Rexing’s lineup for practicality-focused users.

For tech-savvy drivers with older vehicles, the Rexing CP DUO 686 is nothing short of a dashboard resurrection tool—breathing modern connectivity into analog interiors. This open-box multimedia receiver combines wireless Apple CarPlay and Android Auto, a 6.86” HD touchscreen, and a built-in 4K dash cam, all in one sleek unit. It solves the frustration of juggling multiple devices by unifying navigation, media, and safety into a single, voice-controllable hub—perfect for eliminating phone distractions while keeping your car future-ready.

Real-world use reveals strong performance across the board: Bluetooth pairing is instant, streaming audio is crisp, and the integrated dash cam records the road in sharp 4K, with loop recording and collision detection handled seamlessly. The auto-activating backup camera is a standout, flipping the screen to rear view the moment you shift gears. However, being an open-box item, there’s no return option—a gamble if installation goes wrong. Additionally, while the screen is bright enough indoors, direct sunlight can wash it out, and some users note the software interface feels slightly outdated compared to OEM systems.

Against the Rexing CPDuo Pro, the 686 sacrifices screen size and rear camera resolution but retains core CarPlay functionality at a lower entry point. It’s best suited for drivers who want wireless smartphone mirroring without breaking the bank, especially those upgrading pre-2018 models. While it doesn’t offer the panoramic view of multi-cam setups, its all-in-one design makes it a smarter long-term investment than standalone dash cams. For those comfortable with DIY installs, this open-box unit delivers premium features with minimal compromise.

For fleet managers, rideshare veterans, or anyone who demands 360-degree accountability, the Rexing L4 Series isn’t just a dash cam—it’s a rolling surveillance command center. This 4-channel system supports front, rear, and dual side cameras, all recording in synchronized 1080p with 170° ultra-wide lenses and IR night vision, ensuring no angle is left unwatched. What truly sets it apart is the inclusion of a 128GB memory card and 78W quick charger, offering plug-and-play readiness rare at this tier.

In real-world operation, the L4 excels in urban environments where blind spots and side collisions are common. The side cameras mount discreetly on mirrors and capture curb strikes, parking lot dings, and lane-change incidents with stunning clarity. Wi-Fi and app control allow remote access to footage, though the connection relies on ad-hoc tethering rather than home Wi-Fi—a limitation for users wanting automated cloud backups. The supercapacitor ensures stability in extreme heat or cold, but the software interface feels dated, lacking smart alerts or AI-based event tagging found in newer models.

Compared to the Rexing 3-Camera Set for M2-4, the L4 offers greater flexibility with full four-channel support and superior power management. It’s overkill for casual drivers but essential for commercial use where liability protection is non-negotiable. While pricier than dual-channel options, it outperforms them in coverage and durability. Against the similarly priced 4G LTE model, it trades real-time connectivity for broader physical surveillance—making it the go-to choice when local storage and multi-angle recording trump live alerts.

The REXING CPDuo Pro isn’t merely an upgrade—it’s a complete in-car transformation, merging Hollywood-sized immersion with ironclad road protection. Boasting a massive 10.26-inch touchscreen, wireless Apple CarPlay and Android Auto, and a dual dash cam system that records the front in 4K UHD and the rear in 1080p Full HD, it redefines what a rearview mirror replacement can do. For drivers tired of squinting at tiny screens or fumbling with cables, this unit delivers cinematic clarity and seamless connectivity in one bold stroke.

On the road, the CPDuo Pro shines with responsive touch controls, crystal-clear GPS navigation via Google Maps, and flawless Bluetooth calling. The built-in dash cam operates silently in the background, triggering parking mode when hardwired and capturing incidents with sharp detail—even at night. When reversing, the rear camera feed pops up instantly, eliminating blind spots. However, some users report the screen washes out in direct sunlight, and while the resolution is decent, it’s not true 4K, which may disappoint pixel purists.

Stacked against the CP DUO 686, the CPDuo Pro offers a significantly larger screen, better camera integration, and a more polished user experience—justifying its higher price for those seeking top-tier functionality. It’s ideal for older car owners craving modern tech without aftermarket clutter. While not the most compact option, its all-in-one design beats juggling separate GPS, cam, and audio units. Compared to standalone dash cams, it delivers superior convenience and multimedia power, making it the best overall pick for drivers who want it all.

When your original rear camera fails, the Rexing Rear Camera for V1P-4K steps in as a precise, plug-and-play savior—engineered specifically for seamless compatibility with the V1P and V1PGW-4K series. Designed with the same 170° wide-angle lens and night vision capabilities as its counterparts, it ensures consistent video quality between front and rear feeds, eliminating the mismatched resolution issues common with third-party replacements. For owners invested in Rexing’s ecosystem, this isn’t just a part—it’s a critical link in a trusted chain.

In testing, the camera installs easily with minimal wiring, snapping directly into the existing harness for a clean finish. Video syncs perfectly with the front unit, and low-light performance remains strong thanks to integrated IR sensors. However, some users report playback issues—videos freezing or screens going blank—suggesting potential firmware inconsistencies. More critically, if the main dash cam unit is faulty, the rear camera won’t function, making it entirely dependent on host health.

Compared to the Rexing Rear View Camera for V55, this model serves a narrower audience but does so with surgical accuracy. It lacks universal adaptability but excels in faithful restoration of a broken system. For drivers seeking reliability over experimentation, it’s the safest bet. While pricier than generic clones, it avoids the compatibility headaches that plague off-brand alternatives. Against standalone multi-cam systems, it offers less flexibility—but for V1P series owners, it’s the only logical choice for a true 1:1 replacement.

The Rexing Rear View Camera for V55 is the missing piece for drivers who want to transform their front-facing 4K recorder into a full-surveillance powerhouse. As a modular add-on compatible with both the V55 and V5C Plus, it extends protection to the rear with a 170° ultra-wide lens and superior night vision, capturing clear, distortion-free footage even in low-light conditions. For anyone tired of relying on backup cameras with blind spots, this unit fills the gap with military-grade consistency and plug-and-play ease.

Real-world testing confirms it handles rain, fog, and nighttime driving with confidence. The wide-angle lens eliminates blind zones, showing curbs, obstacles, and following vehicles in sharp detail. When paired with the V55, recordings are perfectly synchronized, and loop recording ensures continuous coverage. Installation is straightforward, and customer feedback highlights excellent service and reliability. That said, like all modular units, it depends entirely on the host dash cam—no standalone operation is possible.

Versus the Rexing 3-Camera Set, this rear camera offers less coverage but greater simplicity and lower cost—ideal for drivers who only need rear visibility. It’s not meant for 360-degree monitoring, but for single-purpose enhancement, it’s unmatched. Compared to generic alternatives, it avoids signal interference and resolution drops, maintaining the V55’s premium standard. For existing V55 owners, this add-on delivers maximum ROI with minimal effort, turning a capable dash cam into a comprehensive safety system.

The Rexing V1P Flex X4 is a masterclass in budget engineering—delivering 4K front and 1080p rear recording, dual-band Wi-Fi, and loop recording with G-sensor in a package that undercuts premium models by thousands. For cost-conscious drivers who still demand high-resolution evidence capture, this dual-channel cam solves the biggest dilemma: how to get top-tier video quality without paying luxury prices. Its flexible mounting system and compact design make it a stealthy guardian on any windshield.

In daily use, the Flex X4 impresses with sharp daytime footage and surprisingly good night vision, thanks to WDR and infrared sensors. The included 32GB card gets you started, but it supports up to 512GB of high-endurance storage, perfect for long trips or parking mode loops. Wi-Fi connectivity via the Rexing app allows quick clip downloads, though the connection can be finicky at times. Some users note initial setup confusion, but once running, it operates flawlessly—even in extreme heat, thanks to its robust build.

Compared to the Rexing L4 Series, the Flex X4 sacrifices multi-camera expandability but wins on simplicity and value. It’s not built for fleets or 360 coverage, but for individual drivers wanting dual-channel clarity, it’s unbeatable. Against the open-box CarPlay models, it lacks smart integration but focuses purely on what matters: reliable, high-res recording. For parents, commuters, or rideshare drivers on a budget, it offers the most essential protection at the most accessible price—making it the best budget-friendly dash cam in Rexing’s lineup.

The Rexing 4G LTE Dash Cam is built for the hyper-connected driver who refuses to be blind to their vehicle’s status—even from miles away. With real-time 4G LTE connectivity, secure cloud access, and push notifications for parking incidents, it transforms your car into a smart asset that alerts you the moment something happens. Recording in 2.5K front and 1080p rear, it captures high-resolution footage that’s instantly streamable to your phone, eliminating the need to retrieve SD cards after an event.

In real-world scenarios, the 4G feature proves invaluable: whether you’re at work and hear a crash notification, or checking in on a parked car during a storm, the ability to view live footage remotely adds a layer of security no traditional cam can match. GPS tracks location and speed, and the 64GB included card provides ample local storage. However, the reliance on cellular means performance depends on signal strength, and some users report delays in alert delivery in low-coverage areas.

Against the L4 Series, this model trades multi-camera support for always-on connectivity, making it ideal for urban drivers or those with high-theft-risk vehicles. It’s not designed for 360 coverage, but for instant incident response, it’s unmatched. Compared to Wi-Fi-only models, it offers true remote access without needing to be near the car. While the hardware matches mid-tier cams, it’s the cloud integration that elevates it—making it the best choice for tech-forward users who want their dash cam to do more than just record.

For drivers who demand total visual dominion, the Rexing 3-Camera Set for M2-4 delivers an immersive 360-degree shield with minimal hassle. This weather-resistant trio—comprising rear and dual side cameras—plugs directly into the M2-4 mirror dash cam, extending coverage to blind spots, curbs, and parking lot threats. With 1080p wide-angle recording on all channels and seamless integration with parking mode and G-sensor, it turns your rearview mirror into a command center for total vehicle awareness.

In practice, the side cameras prove invaluable during parallel parking or highway lane changes, capturing near-miss incidents that standard front-rear systems miss. The rear unit activates instantly in reverse, and all feeds sync flawlessly with the main display. Installation is straightforward for those familiar with wiring, though routing cables cleanly takes patience. While the system doesn’t include a front camera (it assumes you already have the M2-4), it completes the surveillance puzzle with precision.

Compared to the L4 Series, this set offers similar 360 coverage but with tighter integration and a cleaner mirror-mount design. It’s less modular but more aesthetically refined—ideal for drivers who hate clutter. Against standalone rear cams, it provides unmatched peripheral vision. While not the cheapest option, its value skyrockets for urban drivers or those with large vehicles. For anyone serious about complete exterior monitoring, this set is the most efficient path to full situational control.
