The China International Optoelectronic Expo – CIOE 2025 in Shenzhen has concluded after three days. Nanjing Weipai Semiconductor Technology Co., Ltd. showcased the latest application developments of the 250-megapixel VPS820 large-area image sensor chip (referred to as the VPS820 imaging chip). This chip not only features ultra-high resolution and an ultra-wide field of view but also demonstrates significant technical advantages and application potential in the high-end security field.
In response to the monitoring needs of modern security systems for long-distance, large-area, and multi-target surveillance, the VPS820 imaging chip, with its 250-megapixel ultra-high resolution and 1.4-micron ultra-small pixel size, allows users to see a larger area while capturing more fine details. It provides a comprehensive solution to traditional monitoring, showing clear advantages in applications such as urban security, coastal defense monitoring, traffic monitoring, forest protection, bridge maintenance, and power inspection.
The chip supports 16 independent ROI (Region of Interest) functions, allowing users to read sensor information from any area, thereby reducing the amount of information read. It can continuously observe targets through a single frame and achieve multi-target synchronous tracking, providing new ideas for control solutions in large events, emergency responses, and anti-drone measures.
The VPS820 imaging chip supports a single-chip pixel scale of 250 million, allowing for an ultra-wide field of view and ultra-high resolution without the need for stitching. Cameras based on this chip can be miniaturized to meet airborne vibration overload requirements, enabling centimeter to decimeter level target recognition at various flight altitudes, including hundreds and thousands of meters.
As a purely domestic 250-megapixel ultra-high-resolution image sensor, the VPS820 not only showcases Weipai’s independent research and development strength and product innovation capability but is also expected to bring innovation to the high-end monitoring field, establishing a new security system characterized by “long-range visibility, clear identification, and rapid response,” providing new ideas for how 100-million-pixel CMOS high-end imaging chips can be better applied in security monitoring and other fields.
It is recommended to watch under Wi-Fi.
