SmartSens Introduces New 4 Megapixel 1/3-inch CMOS Image Sensor for AIoT Applications

Posted Feb 12, 2019 by SmartSens Technology

Leading supplier of high-performance CMOS image sensors, SmartSens, has released the latest 4 megapixel 1/3-inch CMOS image sensor. SmartSens combined leading BSI (back-illuminated) pixel process technology and excellent cost/performance ratio, making the SC4238 an excellent choice for the home IoT monitoring and mainstream consumer camera and professional camera markets.

AIoT (Artificial Intelligence of Things) is not only an inevitable trend of IoT, but also provides excellent intelligent upgrades to traditional industries. For example, analysts predict that the global smart home market will reach over 74 billion USD in 2021. With the rapid development of AIoT, the needs for human-computer interaction are slated to increase. High-quality CMOS image sensor products play an essential part in supporting and enhancing the performance of AIoT. With its extensive experience in security and surveillance monitoring, SmartSens has developed the SC4238 image sensor with professional-grade security product standards.

The powerful performance of SC4238 will enable the AIoT ecosystem and its various applications.

  • 4MP resolution video output: 2688H*1520V effective resolution output is the mainstream product configuration for current home IoT monitoring as well as the consumer camera and professional camera markets.
  • Mainstream 1/3-inch optical size: The SC4238 uses BSI pixel technology to achieve a 2.0μm pixel structure and the mainstream 1/3-inch optical size, with sensitivity of up to 2800mV/Lux*s and maximum signal-to-noise ratio of 39dB. It is highly adaptable and can be used in many fixed focal length lenses, as well as zoom lenses and wide field lenses.
  • 2-Exp HDR at 60fps output support: It delivers great imaging quality in low illumination and highly complex environments. It supports a high dynamic range, with a wide dynamic range up to 100dB in HDR mode and features near-infrared (NIR) enhancement, which can effectively improve the quantum efficiency of the 850nm to 940nm band.
  • Excellent SNR1 ratio: Compared with other 1/3-inch 4 megapixel HDR products in the current market, SC4238 has the advantage of high quality, good performance under ultra-low light condition — SNR1 0.47 vs 1.22, which is about 2.6 times better performance than our competitor.

The launch of SC4238 marks SmartSens' focus on the field of AIoT applications. As one of the leading image sensor companies in the AIoT era, SmartSens' products have been widely used in autonomous driving, face recognition, machine vision and other trending applications.
