Common questions
Questions before you buy
What is a dual-lens dash cam?
It is a system that records two video channels, commonly front and rear or front and cabin, at the same time.
Is a dual-lens car camera better than front-only?
It provides broader evidence, but costs more, uses more storage and normally takes longer to install.
Does adding a rear camera reduce video quality?
That depends on the model. Check the stated simultaneous front-and-rear resolutions rather than assuming both channels use the maximum headline setting.
Can a dual dash cam record while parked?
Many can when connected to a compatible hardwire or constant-power accessory. Parking features and battery safeguards vary by system.
