In the shadowed corners of cities—alleyways, underground garages, and remote rural areas—criminals often exploit the cover of night to carry out illegal activities. Statistics show that nearly 70% of crimes occur after dark. Without effective nighttime monitoring, roads, warehouses, and open fields become vulnerable zones that threaten both urban and community safety. To meet this urgent need, security camera lens technology has made remarkable strides in low-light performance. Two leading solutions have emerged: Black Light F1.0 large-aperture imaging and infrared illumination. These innovations do far more than just let cameras “see” in the dark—they enable systems to see clearly, recognize details, and even understand what they’re seeing, thanks to deep integration with artificial intelligence.

The technical trajectory of security cameras was not an overnight success but a cross-disciplinary evolution spanning two centuries. Its roots can be traced back to the late 19th century with the first attempts to capture continuous dynamic images. In 1870, English inventor Wordsworth Donisthorpe patented the "kinesigraph," a moving picture camera designed to take a series of photos at set intervals to capture movement. In 1889, Donisthorpe and Louis Le Prince further refined film cameras and projection technology; Le Prince even developed a 16-lens camera, which, while more of an experimental tool at the time, laid the physical foundation for continuous monitoring in specific spaces.

M12 interface lenses are widely used in small devices due to their small size, light weight, and low cost.

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.

Panoramic endoscopic imaging is currently primarily applied in capsule endoscopes and large-field-of-view colorectaloscopes. The development of capsule endoscopes is highly diverse, with practical applications ranging from ordinary ultra-wide-angle lenses to the stitching of images from multiple cameras. The large field of view in colonoscopes is mainly achieved through multi-camera image stitching and multi-perspective display. The following section discusses the application of panoramic endoscopic imaging technology in these two types of endoscopes, considering the related diseases requiring diagnosis and treatment.
