On September 3, the conference and military parade marking the 80th anniversary of the victory of China's War of Resistance against Japanese Aggression and the World Anti-Fascist War was held in Beijing. To remember history and honor martyrs, the company organized employee representatives and managers to watch the live broadcast in the hall. At 10 a.m., the parade started; all stood for the national anthem. Formations and equipment impressed, and 80 hero unit flags showed the hard-won victory. Employees were inspired; leaders stressed inheriting the spirit for company and national development.

It’s a scorching summer day, 35°C (95°F) in the shade. You park your car in an open lot to grab lunch. When you come back, you find a fresh scratch on your bumper. You confidently tell the other driver, "Relax, I have a dashcam. Let's look at the footage."

Let’s be honest: nobody likes reviewing security footage that looks like a 1920s silent movie shot in a blizzard. For years, the industry standard for low-light surveillance was Infrared (IR) lighting. It illuminated the dark, but it stripped away all the color, leaving you with grainy, black-and-white images where a red getaway car looks exactly like a blue one. Today, the market demands "full-color night vision." But achieving this without blasting a blinding white LED spotlight into the street requires a specific hardware upgrade. It’s not just about a better software algorithm; it’s about physics. To achieve true, noise-free color footage in near-darkness, your camera needs an F1.0 large aperture lens. Here is a deep dive into why F1.0 is the absolute threshold for modern security cameras, and why the materials inside that lens matter just as much as the numbers on the outside.

The 24th China International Optoelectronics Expo will be held at the Shenzhen International Convention and Exhibition Center from September 6 to 8, 2023.

A wide-angle camera lens is a photographic camera lens with a shorter focal length than a standard camera lens, a larger viewing angle than a standard camera lens, a longer focal length than a fisheye camera lens, and a smaller viewing angle than a fisheye camera lens. Wide-angle camera lenses are divided into two types: ordinary wide-angle camera lenses and ultra-wide-angle camera lenses.
