WHAT’S IN THE BOX? DMS and OMS from Desay SV, LCE and Sunny Smartlead at a glance

Twice a month, Yole Group analysts share noteworthy points from their automotive Teardown Tracks. After 15 DMS (Driver Monitoring Systems) and 4 OMS (Occupant Monitoring Systems) analyzed in 2023, Yole Group continues its investigations into in-cabin cameras, with a special focus on Chinese manufacturers.

Today, Baptiste Desbois, Guillaume Robichon and Maël Fontaine, Technology & Cost Analysts, guide us through innovative DMS/OMS technologies:

In-cabin cameras are expected to show significant revenue growth, with a CAGR of 34.7% from 2022 to 2028 (source: Imaging for Automotive 2023, Yole Intelligence). These systems, serving purposes like driver attention monitoring, occupant monitoring, and biometric driver authentication, contribute to advanced safety features and enhanced user experience, and are gaining in popularity and demand, particularly in China.

The Desay SV and LCE DMS use the same onsemi image sensor, while the Sunny Smartlead DMS employs an OmniVision CIS encountered in previous Yole SystemPlus teardowns:

All these sensors feature global shutter and FSI (Front Side Illumination) technology.

The OMS CIS has 2 Mp resolution, rolling shutter readout, and OmniVision’s RGB-Ir technology, suggesting potential video or photo capabilities beyond its primary function of occupant detection. Due to the use more advanced technology, including BSI (Back Side Illumination), the cost of this sensor is almost twice that of the one found in the Sunny Smartlead DMS.

Unlike the three other systems, the processing for the LCE DMS is entirely externalized. The Desay and both the Sunny Smartlead devices integrate an ISP (Image Signal Processing) chip provided by Nextchip and Fullhan respectively.

Yole SystemPlus teardowns affirm onsemi and OmniVision’s predominance in the CIS market, but as many in-cabin design choices are cost driven, emerging local suppliers like SmartSens could challenge the established international leaders in the near future.

The company covers the overall supply chain from the components to the system. Based on daily technical and industrial monitoring, Yole SystemPlus has significant expertise to support innovation.

Baptiste Desbois serves as Technology & Cost Analyst at Yole SystemPlus, part of Yole Group.

With solid expertise in the analysis and the troubleshooting of electronics boards, Baptiste produces reverse engineering & costing analyses while also working on custom projects for the electronics systems teams. His mission is to identify and analyze the components during the disassembly of the device and cutting of the electronic boards and determine the final manufacturing cost. This will provide the raw information to produce the reverse costing reports.

Prior to Yole SystemPlus, Baptiste worked as a bench test validation technician for Sercel (Nantes, France)

Baptiste holds a BTS Digital Systems Option B: Electronics and Communication and a professional license in mechatronics from E.S.P.R.I.T Campus (Redon, France).

Guillaume Robichon serves as a Technology & Cost Analyst at Yole SystemPlus, part of Yole Group.

With solid expertise in the analysis of component quotes, component price estimates, and system encryption, Guillaume produces the engineering & costing analyses while also working on custom projects for the electronic systems teams.

His mission is to identify and analyze the device’s components during the disassembly and cutting of electronic boards and determine the final manufacturing cost.

Guillaume holds a University Diploma in Technology in Electrical Engineering and Industrial IT (Université de Nantes, France).

Maël Fontaine serves as a Technology & Cost Analyst at Yole SystemPlus, part of Yole Group.

With solid expertise in the analysis of electronics boards, Maël produces reverse engineering & costing analyses while also working on custom projects for the electronic systems teams. His mission is to identify and analyze the components during the disassembly of the device and cutting of the electronic boards and so determine the final manufacturing cost.

Prior to Yole SystemPlus, Maël worked in an electrification system engineering office in Tours.

Maël holds a license in Design, Study and Production of Digital and Analog Electronics at Tours University (France).
