Rexing R4-RD vs R4 Comparison

Camera configuration

Edge: Rexing R4-RD 4-Channel 1080p Dash Cam

Both models feature a four-channel setup with 1080p resolution for front, rear, and side views. The R4-RD includes dual side cameras that rotate inward for optional cabin coverage. This design supports rideshare and fleet use by capturing interior activity alongside external road conditions. The R4 also offers four channels with left and right cameras that can face the cabin. Each side unit on the R4 includes four infrared lights to aid visibility. Both systems provide comprehensive external coverage, but the R4-RD explicitly highlights its suitability for professional drivers needing interior monitoring capabilities.

Parking protection

Edge: Rexing R4-RD 4-Channel 1080p Dash Cam

The R4-RD comes with an OBD Smart Hardwire Kit included in the box. This kit provides continuous power for 360-degree parking monitoring without requiring additional purchases. It supports constant power and motion detection to capture events from multiple directions. The R4 also features parking mode with motion and impact detection. However, the R4 requires a separate Type-C smart hardwire kit for this function, which is not included. This means R4-RD users get immediate parking protection setup, while R4 users must buy the hardwire kit separately to enable continuous monitoring features.

Night vision

Edge: Tie

Both dash cams utilize infrared technology to improve visibility in low-light conditions. The R4-RD features infrared-equipped side cameras that help capture clearer side or cabin footage at night. This ensures dependable coverage during nighttime driving across all channels. The R4 also incorporates infrared night vision, with each left and right camera equipped with four IR lights. This allows for better visibility of the cabin or side areas when ambient light is low. Both models rely on this infrared assistance to maintain clarity during evening hours, providing similar night-time performance for interior and side views.

Connectivity and control

Edge: Tie

Both units offer built-in Wi-Fi and connect to the Rexing Connect App for control. You can preview, download, and share recordings directly to your mobile device using the app on both models. The R4-RD supports app control for managing recordings and settings. The R4 also uses the Rexing Connect App for high-speed video file transfers. Both systems include built-in GPS to record location, route, and speed data. You can review this trip data using the Rexing GPS Player. The connectivity options and control methods are identical, ensuring a consistent user experience for managing footage on both devices.

Field of view

Edge: RexingUSA R4 4-Channel 1080p Dash Cam

The R4 specifies a real angle of view of 140 degrees for its cameras. This wide field of view captures more of the road ahead and surrounding areas. The R4-RD data does not explicitly list a specific degree measurement for its field of view. Both models provide 1080p resolution to ensure clarity and detail in the footage. The R4’s stated 140-degree view helps capture important details without losing context when zooming in. Without a specific angle listed for the R4-RD, it is difficult to compare the exact width of coverage, though both aim for comprehensive all-around recording.
