4K 3 Channel Dash Cam C3 - Front, Cabin and Rear Recording

Our review of the SARMERT C3 4K 3 Channel Dash Cam finds it best for drivers who want full coverage and clear evidence collection without fiddly setup. The dash cam stands out for its simultaneous 4K front plus dual 1080P cabin and rear recording, which delivers crisp daytime detail and impressive night vision thanks to F1.8 optics and infrared illumination. The built-in GPS and 5G WiFi make it easy to tag and transfer clips, while the adjustable recording modes let users tailor which cameras are active for any trip.

Key Features

• 3 Channel Recording: Front 4K and two 1080P channels capture the road, cabin, and rear view at once so you do not miss an incident from any angle.
• 4K Front Clarity: The front lens uses a fast F1.8 aperture and six-layer glass to produce sharper daytime and low-light images for clear license plate and detail capture.
• Advanced Night Vision: Four IR lights and WDR processing improve contrast and visibility in dark conditions for reliable overnight footage.
• 5G WiFi and App Access: Connect to the RoadRec App over 5G WiFi to quickly view, save, and share videos from your phone without removing the card.
• G-Sensor and Loop Recording: Variable sensitivity impact detection automatically locks collision clips while loop recording manages storage by overwriting oldest files.
• Flexible Recording Modes: One-click menu switching lets you choose full 3-channel capture or dual-mode front+interior/rear depending on your needs.

Who It's For

The SARMERT C3 is ideal for rideshare drivers, families, and owners of high-value vehicles who want comprehensive coverage of both exterior and interior activity, and who value fast wireless transfer and GPS route logging. Its multi-camera layout gives peace of mind for trip disputes, passenger monitoring, and parking incidents when combined with a hardwire kit.

Drivers who only need a simple single-channel front cam or who lack a suitable power-hardwire option for 24-hour monitoring may prefer a simpler unit. Also, users who require ultra compact single-lens solutions should look elsewhere rather than a three-camera system.
