Overview
Image sensors are installed in security cameras and are widely used for security measures in a wide variety of facilities and for safety maintenance in urban environments. Recently they have also been widely adopted in other fields such as home security and dashcams. Sony Semiconductor Solutions Corporation contributes to achieving a safer society with a wide sensor lineup. These devices range from image sensors for security cameras with high sensitivity, low noise, and excellent dynamic range characteristics to event-based vision sensors that enable privacy-friendly monitoring in nursing facilities.
Applications
Street monitoring
Security camera image sensors are widely used for safety measures in urban environments.
Shooting in an urban environment requires high imaging performance because there is substantial variation in ambient brightness compared to indoor shooting. Sony’s security camera image sensors satisfy this requirement with an advanced imaging capability — these sensors have both low-noise and high-sensitivity characteristics and prevent white clip and blackout even at night and in highly variable lighting conditions, contributing to the maintenance of a safe society.
Event-based vision sensors, which can detect the movement of a subject without being affected by the lighting environment, are also effective in monitoring the movement of people. They can be used in combination with standard security camera image sensors, enabling creation of a higher-performance monitoring system.

Facility surveillance
Security measures in commercial, financial, and airport facilities require image sensors suited to their respective objectives and conditions. For example, in crowded areas with people moving about, image sensors need features such as high resolution and a wide angle of view while, for security measures in buildings after lights out, they require high imaging performance in dark locations. Sony’s wide range of security camera image sensors cater to all these different needs and more.
In addition, Time of Flight (ToF) image sensors are useful for checking the congestion status of stores, airports, theme parks, and other venues. They can also monitor open/close status of automatic doors and manage the entry/exit at facilities. Even in situations where people appear closely overlapped, which is difficult to judge with two-dimensional sensors, multiple people can be easily distinguished and the number of people can be counted accurately.

Disaster risk monitoring
Natural disasters like flooding rivers and landslides in mountainous areas have become a social problem in recent years. Given this, there are strong needs for solutions like SPRESENSE™ ,board computer for IOT , which can predict disasters early by using AI to analyze information collected from sensors, such as cameras and microphones. SPRESENSE™ is low power consumption, so it can run on batteries or other external energy harvesting sources (environmental power generation). Its compact size also allows installation in many versatile and remote locations.

Elder care and monitoring
The shortage of care workers has become a social issue in recent years. It is possible to support care workers with monitoring the elderly by using the SPRESENSE, board computer for IoT to combine collecting of various types of data with edge computing image processing AI, audio analysis processing, and analysis processing data from various sensors.
GNSS receiver LSI and constant sensing function with low power consumption enables to monitor the behavior of the elderly and to provide a safe living environment.
Home security systems
Security camera image sensors are also used to enhance home security. They can be used for a variety of purposes, including guarding the house during a long period of absence and keeping an eye on elderly or young members of the family at home. These sensors can capture clear images even at night and in environments with highly variable lighting conditions.

Dashcam
Demand is rapidly increasing for devices to record traffic accidents and incidents of road rage, which have become a social problem in recent years. With high-sensitivity, low-noise, and wide-dynamic-range technology, Sony's security camera image sensors capture critical footage regardless of the time of day or the shooting location.
