Unique In-Cabin Design

Designed as a behind-windshield lidar, improves aerodynamics,  dust and dirt free

Low Power For Better Thermal Performance

The rearview mirror tends to get very hot under the sun, which requires the in-cabin lidar to
 have low power consumption to avoid overheating

Quiet Library
*Every increase of 10 dB(A) (decibels) is equal to a 10-fold increase in sound intensity. A 20 dB(A) increase raises the sound intensity by 100 times, a 30 dB(A) increase raises the sound intensity by 1000 times, and so on. The dB(A) representation is shown in the figure above. The values are sourced from internal test results and are for reference only.
