Design and Build Quality

The Rexing V1 dash cam boasts a sleek, low-profile design that mimics the look of a rearview mirror module. Its black matte finish blends effortlessly with most vehicle interiors, making it unobtrusive and discreet. The compact body ensures it doesn’t interfere with your field of vision, and the buttons are conveniently located for intuitive use.

The device is built with high-quality materials and feels solid in hand. It uses a supercapacitor instead of a traditional lithium battery, allowing it to better handle extreme temperatures—ideal for drivers in both hot and cold climates.


Video Quality and Lens Performance

4K Ultra HD Clarity

The camera’s standout feature is its 2160p resolution, offering four times the clarity of standard HD cams. This level of detail is crucial when capturing events like accidents, hit-and-runs, or roadside incidents. License plates, signs, and even facial details can be clearly recorded, even in complex lighting conditions.

The 170-degree wide-angle lens ensures maximum road coverage without creating fish-eye distortion. This helps in capturing vehicles in adjacent lanes and pedestrians on the sidewalks—all essential for comprehensive incident documentation.

Night Vision Performance

Thanks to its advanced image sensor and wide dynamic range (WDR) technology, the Rexing V1 handles low-light situations impressively. Night footage remains clean and relatively noise-free, with good detail retention. Headlights and streetlights are balanced effectively, avoiding overexposure and glare.


Smart Features and Functionality

Wi-Fi and Mobile App Control

The built-in Wi-Fi feature allows you to connect the dash cam directly to your smartphone via a companion app. Through the app, you can view live footage, download recordings, and adjust settings without removing the SD card. This is especially useful when you need to quickly access a video clip for evidence or sharing.

Loop Recording and G-Sensor

Loop recording ensures that the camera continuously records by overwriting the oldest files when the memory card is full. Meanwhile, the integrated G-sensor detects sudden movements, such as collisions or harsh braking, and automatically saves that footage in a protected folder that won’t be overwritten.

Supercapacitor Advantage

Instead of a lithium battery, the Rexing V1 uses a supercapacitor. This enables the camera to function in a wider range of temperatures, improving longevity and safety. It also ensures the camera powers off properly after the engine stops, reducing the risk of file corruption.

Optional GPS Logging

While not built-in, the Rexing V1 is compatible with an optional GPS module that logs speed, route, and location data. This is beneficial for insurance claims, delivery services, or fleet tracking. GPS data can also be overlaid on video playback for context.


Installation and Setup

The Rexing V1 can be easily mounted to the windshield using either the included adhesive or optional suction cup mount. Its lightweight and compact design make it suitable for placement behind the rearview mirror. The camera powers on with the ignition and starts recording automatically, requiring no daily interaction.

Setup is straightforward through the on-screen menu or mobile app, with clear options for resolution, recording mode, G-sensor sensitivity, Wi-Fi setup, and more. Once configured, it operates quietly in the background, always ready to record.
