C4 vs M2: Key Specs Compared

camera configuration

Edge: Rexing C4 4-Channel 1080p Dash Cam

The Rexing C4 offers a four-channel setup, capturing four simultaneous views in 1080p. This includes front, rear, and two side cameras, plus a cabin camera with infrared night vision. You get broader coverage of your vehicle's surroundings. The M2 records dual channels in 1080p, focusing on front and rear perspectives. It functions as a mirror dash cam, providing a live stream of the rear view on a 12-inch screen. While the C4 captures more angles simultaneously, the M2 prioritizes a clear, wide rear view for lane changes. The C4 provides more comprehensive multi-angle recording.

connectivity

Edge: REXING M2 12-inch Dual Mirror Dash Cam

Control methods differ significantly between these two models. The C4 relies on Wi-Fi connectivity, allowing you to connect your smartphone to the camera's local network. You use the Rexing Connect app to review recordings, download clips, and adjust settings. This keeps the main unit free of bulky interfaces. The M2 features a 12-inch IPS touchscreen, enabling you to operate commands directly with your finger. You can view footage and settings without needing a phone. The M2 offers immediate, local control, while the C4 requires a smartphone for interaction. The M2 is more convenient for quick adjustments.

included storage

Storage options vary right out of the box. The C4 bundle includes a 64GB microSD card, helping you start recording immediately. Loop recording automatically overwrites older, unlocked videos to keep the cycle going. The M2 does not list included storage in its specifications. You would need to purchase a memory card separately to begin using this device. Having the card included with the C4 reduces initial setup steps. This makes the C4 more ready-to-use for drivers who want to avoid buying extra accessories. The C4 has the advantage here.
