Common questions
Questions before you buy
What is a three-channel dash cam?
It is a system that records front, rear, and cabin views. Confirm that all three channels operate together at the specifications you expect.
Do front, rear, and inside dash cams record at the same time?
Purpose-built three-channel systems are designed to do so, but available resolution or frame rate may change when every channel is active. Read the exact recording-mode table.
Is infrared necessary for an inside dash cam?
Infrared illumination can improve cabin visibility in darkness, especially when there is little ambient light. Review real sample footage and whether reflections affect glasses or windows.
How much storage does a three-channel dash cam need?
It generally uses storage faster than a single-camera setup. Choose a card type and capacity explicitly supported by the manufacturer and estimate retention from the documented bitrates.
