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

Low Noise For A More Comfortable In-Cabin Experience
With a noise level of less than 25 dB(A), the ET25 brings a more comfortable in-cabin experience for the driver and passengers
Peaceful Night in the Countryside
Noise Level of ET25
*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 below. The values are sourced from internal test results and are for reference only.
Solving Signal Attenuation with AR-Coated Windshield**, Does Not Compromise Ultra-High Performance
