Dual-Lens Dash Cams for Two-Angle Coverage

It means the system records from two cameras. The second lens may face the rear road or the cabin, so check the exact configuration rather than relying on the phrase alone.

Not always. Some dual-lens models put a cabin-facing lens beside the front lens, whereas a front-and-rear kit uses a separate camera at the back of the vehicle.

Models designed for dual-channel recording can save both views simultaneously. Confirm the supported resolution for each channel and use the memory-card specification in the manual.

Point it rearward if you want traffic coverage behind the car, or inward if rideshare, passenger, or cargo activity matters more. Local privacy and audio-recording rules may apply to cabin footage.
