At present, the security industry is developing rapidly in the direction of digitalization, intelligence, super HD, etc. The future growth space of the whole intelligent security industry is quite broad. This also puts forward higher requirements for the imaging performance of security CMOS image sensors.

 

 

Recently, SmartSens, the advanced CMOS image sensor supplier, officially launched three full performance upgrade Pro Series image sensors (hereinafter referred to as "P Series") for security applications, SC2336P, SC3336P and SC4336P. As a new series of performance upgrades, P series products cover 2MP to 4MP video solutions, using advanced 12-inch wafer process, and equipped with the innovative SFCPixel® patented technology and ultra-low noise peripheral readout circuit technology, in the night vision full color, high-temperature imaging and low power consumption performance aspects have excellent performance, and strive to outstanding high-performance imaging to enable the development of intelligent security video applications. The company's innovative SFCPixel® technology and ultra-noise peripheral reading circuit technology provide excellent performance in night vision, full color, high temperature imaging and low power consumption.

 

 

 

 

Upgrade DSI-2 Technology

 

Create excellent dark light imaging and color performance

 

The new P series products are based on the upgraded DSI-2 technology, equipped with Stowe's innovative SFCPixel® patented technology and ultra-low noise peripheral reading circuit technology, to achieve a comprehensive improvement in imaging performance. The new product has been designed to reduce the thickness of the inner dielectric layer, making the metal layer lighter and thinner, thus improving the overall photosensitivity performance. The SC4336P, for example, is a 2.0μm small pixel size sensor with 18% lower SNR1s than its predecessor, while its sensitivity (A-light) has increased by 25%, achieving a dark light imaging performance comparable to that of the industry's 2.3μm pixel size sensors, making details in dark areas more visible.

 

In addition, the P series new products are equipped with a fully optimized color process and advanced Microlens new process, and the use of the industry's top materials to create Color Filter, to enhance the color reproduction at the same time, to achieve imaging effects comparable to the BSI process. Compared to the industry with the same specification products, SC4336P Chroma high and low color temperature were relatively improved by 9% and 12%, the image picture is more vivid and not distorted.

 

 

 

Fearless of high temperature and harsh challenges

 

Imaging performance is still outstanding

 

Security cameras need to deal with the limited space for a long time and outdoor exposure to the high temperature working environment, and the high temperature will often make the image sensor image quality degraded. The SC4336P, for example, has a Shading lower than 3e- and a DSNU less than 0.8e-, which eliminates the purple edge phenomenon caused by high temperature and enables the camera to output high quality images even in a high temperature environment. This enables the camera to output high quality images even in high temperature environments.

 

 

Thanks to the outstanding low-power design of Storwell, the P series products can precisely control the modules within the chip through configuration upgrades, thus achieving excellent low-power performance. Take SC4336P as an example, compared with its predecessor, its power consumption has been significantly reduced by 22%, which can be used for intelligent security emerging applications.
