Hardware and Design Features

The Rexing M2 showcases a 4‑channel mirror design, integrating side‑view cameras for comprehensive coverage. Its LCD mirror toggles between reflective mode and live video, while built‑in parking mode and park‑assist features enhance safety. Ideal for modern vehicles!

4-Channel Mirror Dashcam Architecture

The Rexing M2’s core is a four‑channel mirror system that fuses front, rear, and dual side cameras into a single, seamless display. Each channel is driven by a high‑resolution sensor that captures 1080p video at 60 fps, ensuring crisp detail even in low‑light conditions. The front camera is positioned directly behind the rear‑view mirror, while the rear camera sits on the rear‑view mirror’s base, providing a true rear‑view feed. Two side cameras flank the mirror, each covering a 120° field of view to capture lane changes and blind‑spot activity. The architecture uses a single HDMI‑compatible output that multiplexes all four feeds into a 5.5‑inch LCD panel, allowing the driver to switch between live view, recorded playback, and a static mirror mode with a single button. The system’s firmware automatically balances exposure across all channels, preventing glare and ensuring consistent brightness. Power is supplied through a 12‑V to 5‑V DC‑DC converter that runs off the vehicle’s accessory power line, eliminating the need for separate wiring harnesses. The unit’s compact 3.2‑inch chassis houses a 1.5‑inch battery backup that keeps the cameras running for up to 30 minutes during a power outage, preserving critical footage. The mirror’s reflective surface is engineered with a 0.8‑mm anti‑glare coating, which reduces glare from headlights and streetlights while still allowing the LCD to display high‑contrast video. The architecture supports both “park mode” and “park assist” functions; when the vehicle is off, the cameras continue to record, and the system automatically flags any detected motion. All four channels are synchronized via an internal real‑time clock, ensuring that timestamps match across all footage. The design also incorporates a heat‑sink and a 12‑V fan that keeps the unit below 45 °C during extended operation. Finally, the M2’s modular design allows for future firmware updates that can add new features such as lane‑departure alerts or driver‑monitoring, making the 4‑channel architecture a flexible foundation for next‑generation vehicle safety systems.

Side Camera Technology and Field of View

The Rexing M2’s side cameras are engineered with a 1.3‑inch CMOS sensor and a 4‑mm focal‑length lens that delivers a 120° horizontal field of view, capturing lane markings and adjacent traffic with high fidelity. Each side unit is mounted flush with the mirror’s outer frame, ensuring minimal blind spots while preserving the mirror’s reflective surface. The cameras employ a dual‑stage image‑processing pipeline: first, a low‑latency motion‑detection module flags potential hazards; second, a high‑dynamic‑range (HDR) algorithm blends multiple exposures to maintain detail in both bright and shadowed areas. This HDR capability is crucial for night‑time driving, where glare from oncoming headlights can otherwise obscure peripheral vision. The side cameras support 1080p recording at 60 fps, and the firmware automatically adjusts frame rates to 30 fps during low‑light conditions to conserve memory and reduce power consumption. Connectivity is handled via a single 4‑wire cable that carries both power and data, simplifying installation and reducing clutter behind the dashboard. The side camera modules are temperature‑controlled, with an integrated thermistor that triggers a 5 V fan when the unit exceeds 50 °C, ensuring consistent performance in hot climates. For parking mode, the side cameras remain active, continuously monitoring for motion and sending alerts to the driver’s smartphone via a companion app. The field‑of‑view is calibrated during factory testing to match the vehicle’s geometry, so the driver sees an accurate representation of the roadside environment. The side camera system can be configured to display a split‑screen view, overlaying the front camera feed with side views, or to switch to a single‑camera focus depending on driving context. Firmware updates can add new features such as lane‑departure warnings or adaptive brightness controls, making the side camera technology both robust and future‑proof.

LCD Mirror Display and Reflective Mode

The Rexing M2 integrates a 5‑inch capacitive touch LCD that doubles as a rear‑view mirror. When the vehicle is off, the display remains in reflective mode, providing a clear, glare‑free view of the road. Activating the dashcam—either by pressing the power button or via the companion app—switches the screen to live video, overlaying the front camera feed with real‑time telemetry such as speed, GPS track, and lane markers. The touch interface allows drivers to toggle between full‑screen video, split‑screen with side cameras, and a monochrome “night‑vision” mode that enhances low‑light detail. The mirror’s reflective surface is engineered with a 0.3‑mm anti‑glare coating, reducing reflections from headlights and streetlights while maintaining high contrast for the video overlay. Power is supplied through a 12‑V DC connector that also feeds the side cameras, ensuring synchronized operation. The display’s brightness is auto‑adjusted based on ambient light sensors, dimming in daylight to preserve battery life and brightening at night for better visibility. Firmware updates can add features such as a “focus‑on‑lane” overlay, which highlights lane boundaries when the vehicle is in autonomous mode. The mirror’s design includes a recessed bezel that houses the camera’s optical sensor, preventing damage from road debris. For parking mode, the LCD can be set to a “parking view” that displays a 360° stitched panorama from all cameras, allowing the driver to monitor the vehicle’s surroundings without moving the head. The system also supports a “mirror‑only” mode, where the display remains reflective even when the dashcam is active, useful for drivers who prefer a traditional mirror appearance while still recording.

Installation and Setup

Mount the main unit on the windshield, align the LCD mirror, and connect the 12V power cable to the vehicle’s fuse box. Wire side cameras to the main unit’s 4‑port connector, then power on and follow prompts to enable parking mode and GPS.
