In order to effectively carry out heatstroke prevention and cooling work during the high temperature season, enhance the awareness of high temperature labor protection among employees, effectively prevent the occurrence of high temperature heatstroke and various accidents, and safeguard the labor safety and health rights and interests of employees.

A camera lens does more than "focus light"—it manages light through multiple optical elements, controlling refraction, aperture, aberrations, and chief ray angle (CRA) to deliver a usable image to the sensor. The image circle must cover the sensor; edge performance and MTF matter as much as center sharpness. Aperture size affects low-light capability but increases aberration challenges. Lens and sensor selection should happen together, as pixel size, field of view, and optical coatings all influence final image quality. Boshi Optics designs lenses for security, AI, drones, automotive, and medical imaging, integrating design, molding, assembly, and testing for consistent performance.

For many years, infrared illumination has been the standard solution for security cameras working at night.When the environment becomes dark, the camera turns on IR LEDs, switches to black-and-white mode, and continues recording.This technology is reliable and remains widely used today. However, the security industry is changing.
