Backup cameras aid reversing, while rearview cameras show traffic behind while driving
A backup camera shows the area behind a vehicle when the driver selects reverse, helping with parking and avoiding nearby obstacles. A rearview camera provides a continuous view of traffic behind the car while driving, and some models can also record incidents.
Backup cameras commonly offer a wide 150- or 180-degree view, guidance lines and proximity alerts. US vehicles from model year 2018 and newer are required to have them, while a similar EU requirement took effect in 2022; continuous rearview cameras are not standard on all new cars. Aftermarket cameras are available, with backup camera add-ons ranging from $40 to more than $400, and rear dash cameras can sometimes serve both purposes.
- Backup cameras switch on in reverse to aid manoeuvring.
- Rearview cameras show traffic behind the car continuously.
- Backup camera add-ons cost from $40 to over $400.

A backup camera activates when a driver selects reverse, displaying the area directly behind the vehicle on a screen. This helps drivers see obstacles, pedestrians, and other vehicles that are hidden from view, making parking and manoeuvring safer.
A rearview camera works continuously whilst the car is driving, rather than only when reversing, providing a live view of traffic and activity behind the vehicle. Some rearview systems also record video, which can serve as evidence if the car is involved in a collision or incident on the road.
Backup cameras are now legally required on new vehicles in the United States and European Union, reflecting their value as a safety feature. Rearview cameras remain optional on most new cars, though drivers can add either type to older vehicles through aftermarket options, with costs varying significantly depending on the system.
