Wireless backup cameras offer older cars a simpler way to see behind
Many newer cars have backup cameras, but older cars can be fitted with an add-on system.
A wireless camera mounted at the rear sends live video to a screen on the dashboard, usually over Wi-Fi or a dedicated radio signal.
Most systems work without mobile data, and prices range from $40 to more than $400.
Some cameras connect to the car’s rear-light wiring and turn on when the driver shifts into reverse; battery- or solar-powered models may need to be activated through a phone app.
Their wide-angle image is flipped to resemble the view in a rearview mirror.
Unlike many built-in systems, most add-on cameras do not measure distance or warn drivers with a beep, so drivers must judge obstacles from the video.
Wireless signals can face interference, and the image may arrive with a slight delay.
Wireless backup cameras can give older cars a rear view without a complex wired installation.
They send live video from the rear of the vehicle to a dashboard monitor.
Many models can be installed by the vehicle owner and do not need mobile data.
Prices range from $40 to more than $400.
Unlike many factory systems, they may not measure distance or alert drivers to obstacles.
