Camera Setup and Coverage Comparison
Camera Configuration
Edge: Rexing C4 4-Channel 1080p Dash Cam
The Rexing C4 offers a four-channel recording setup, capturing views from the front, rear, cabin, and an additional side angle simultaneously. This configuration provides a comprehensive record of your vehicle's surroundings and interior. In contrast, the Rexing S3 is a three-channel system, focusing on the front windshield, the cabin interior, and one side door. While the S3 covers the most critical areas for rideshare or personal use, the C4 adds a second side camera for broader exterior coverage. You should choose the C4 if you need complete four-way visibility, or the S3 if you prefer a simpler three-camera arrangement.
Included Storage
Edge: Rexing C4 4-Channel 1080p Dash Cam
When you purchase the Rexing C4 bundle, it comes with a 64GB microSD card pre-included in the box. This means you can start recording immediately without needing to buy memory separately. The S3 product data does not list any included storage capacity, so you will likely need to source a compatible microSD card on your own. For buyers who want a ready-to-use experience right out of the package, the C4 provides immediate value by handling the storage requirement. If you already have high-endurance cards, this difference may matter less to you.
Connectivity Features
Edge: Rexing S3 3-Channel 1080p Dash Cam
Both dash cams utilize Wi-Fi connectivity to allow smartphone app control, letting you review footage and adjust settings remotely. However, the Rexing S3 includes built-in GPS capabilities, which record your speed, location, and route data directly onto the video files. This feature is useful for verifying driving routes and speeds. The C4 specifications do not mention built-in GPS, so it relies solely on Wi-Fi for data management. If tracking your driving path and speed is important for your records, the S3 offers this additional layer of information that the C4 lacks.
Control Method
Edge: Tie
Both units rely on a mobile app for primary control and video management, ensuring you can access your recordings from your iOS or Android device. The Rexing C4 specifies app control as its main interface method, allowing you to download clips and change settings via the Rexing Connect app. The S3 also uses Wi-Fi and a mobile app for viewing and managing videos, with added GPS player features. Since both products depend on smartphone connectivity for operation rather than physical buttons on the device for complex tasks, they offer a similar level of digital convenience for reviewing your drives.
Build and Power
Edge: Rexing S3 3-Channel 1080p Dash Cam
The Rexing C4 is battery-free and uses a USB Type-C power connection, requiring an external power source during operation. It weighs 5 ounces and measures 5.51 inches in length. The S3 features a supercapacitor for enhanced temperature resistance, which is beneficial in extreme climates. It is slightly wider at 4.5 inches but shorter in length at 1.5 inches. The C4 offers flexible mounting with both adhesive and suction cup options included. The S3 mentions simple windshield mounting. Both designs prioritize reliable power delivery, though the S3's supercapacitor may offer better longevity in heat.
