The professional front radar can still work for about 10 seconds after power failure.
Difference 2: Â Smart start: When the sensor does not detect an obstacle, the front vehicle radar does not start, so as to prevent the light from the display from affecting driving safety.
Difference 3:
A professional front-end radar should have a detection range of around 1.5 meter, as the driver can clearly see obstacles beyond 1 meter
As shown in the following figure: When waiting for a red light, if a useless alarm is generated due to the detection distance being too far, it may sound annoying

Two conditions for the operation of front-end radar
1: When braking
2: When the sensor detects an obstacle
When the distance is 1M~1.5M, it is a safe distance. The display only displays numbers and does not generate an audible alarm to avoid disturbing the driver.
When the distance is 0.3M~1M, it is the warning distance. The display shows numbers and emits a heartbeat sound alarm. Â (BI BI…..BIBIBI…..BIBIBIBIBI…..BIBIBIBIBIBIIBIBIB……..
