Recently, SITW launched a new series of Internet of Things (IoT) image sensors, the SC256HIOT (2.6MP) and SC630HIOT (6MP). Both back-illuminated products are based on SmartClarity-3 and SmartClarity-2 process technologies, equipped with InSensor HDR single-frame high dynamic range technology, SFCPixel, and other technologies, offering advantages such as high dynamic range, high sensitivity, and low noise, enabling IoT cameras to capture clear, high-quality images without motion blur in various environments with strong light contrast and low illumination. Meanwhile, SC256HIOT and SC630HIOT adopt a 1:1 aspect ratio, which helps fisheye lenses achieve a more complete imaging field of view, meeting the wide field angle upgrade needs of various IoT applications such as smart doorbells, visual door locks, and fisheye panoramic monitoring.
SC256HIOT and SC630HIOT adopt a 1:1 aspect ratio, providing complete field of view imaging for cameras in both horizontal and vertical scenes. Compared to traditional 4:3 or 16:9 rectangular aspect ratios, the 1:1 square aspect ratio can more accurately fit the circular field of view of fisheye lenses, avoiding information loss at the vertical edges in scenes like doorways, fully adapting to the panoramic coverage needs of smart doorbells/ door locks, and fisheye monitoring in IoT applications.
By incorporating InSensor HDR technology, SC256HIOT and SC630HIOT achieve single-frame high dynamic image output, with maximum dynamic ranges of 87dB and 80dB. Compared to traditional Staggered HDR modes, InSensor HDR effectively improves the tailing and ghosting issues when capturing moving objects. Additionally, InSensor HDR supports DR100, DR200, DR400 three different gain ratios, suitable for different scenes with uniform lighting, moderate light contrast, and strong light contrast, ensuring highlights are not overexposed and dark areas are clearer. Furthermore, InSensor HDR technology supports on-chip single-frame multi-gain image fusion, helping the main control unit optimize memory usage, improve operational efficiency, and reduce cost inputs.
In home security applications such as smart doorbells and visual door locks, cameras often face environmental challenges like insufficient light at the door. Based on a back-illuminated pixel architecture design, SC256HIOT incorporates SFCPixel technology and Lightbox IR near-infrared enhancement technology, achieving excellent sensitivity in both visible and near-infrared bands. Compared to previous products, SC256HIOT has significantly improved peak quantum efficiency ( peak QE) by about 28% at the 520nm band, and peak quantum efficiency ( peak QE) has increased by about 51% and 1.6 times at the 850nm and 940nm bands, respectively, while its read noise ( RN) is as low as 0.64e-. Therefore, the infrared light activation time for doorbell cameras using this product can be significantly reduced, effectively lowering the camera’s operational power consumption and heat generation.
As a series of IoT image sensors, SC256HIOT and SC630HIOT feature 1:1 aspect ratio, high dynamic range, and other advantages, with different resolutions to meet various application needs. The SC256HIOT has a 2.6MP resolution and 2.9μm large pixel size, and is equipped with Lightbox IR technology, providing reliable support for low-light imaging in smart doorbells, door locks, and other devices. The SC630HIOT features 6MP high resolution, capable of delivering real and clear high-quality images, suitable for smart doorbells and other close-range applications, while also meeting the fisheye panoramic monitoring needs in larger areas such as courtyards and garages. Both products have been sent for sampling and are expected to achieve mass production in Q1 2026.
