Common questions
Questions before you buy
What is a single channel dash cam?
It is a dash camera that records one video channel, usually through a forward-facing windscreen camera.
Is a front-only dash cam enough?
It can document many forward incidents, but it will not directly record a rear impact or activity behind the vehicle.
Can I add a rear camera later?
Only if the front unit has a compatible camera port and the manufacturer sells the matching rear module. Check before buying.
Does one camera use less storage than two?
Generally yes at comparable resolution and bitrate, because only one stream is written. Actual recording time still depends on settings and card capacity.
