Analysis of Fog Transmitting Technology for Surveillance camera imaging

The principle of Surveillance camera imaging is that the light emitted or reflected by the target object is converted into an image on the imaging device of the camera. When there is haze in the monitoring environment, the increase in aerosol or solid particle density in the atmosphere will cause a series of blocking, scattering, refraction and other effects on the light beam in the propagation path, reducing the effective light that can enter the camera. At this time, the camera's fog transmission technology can provide protection for monitoring.

High-definition network camera fog penetration technology refers to the use of technical means to reduce the interference of haze on imaging, allowing cameras to achieve good monitoring results. There are currently two main ways to achieve fog penetration: one is electronic fog penetration (also known as digital fog penetration), which processes the collected images through algorithms to improve clarity and color saturation; The second is optical fog transmission (also known as physical fog transmission), which changes the quality of optical imaging through physical means to achieve fog transmission effect.

Electronic fog is implemented on cameras or backend software, and is a backend image restoration technology designed based on human visual perception models. It has the characteristics of low cost and easy deployment; Optical fog transmission is mainly achieved by camera lenses, and high-definition fog transmission lenses are generally only realized in large electric zoom lenses in the industry, which are expensive and generally used in scenes such as ports and forest high points.

The use of Network monitoring camera has reduced the impact of haze weather on camera monitoring to a certain extent, which helps maintain normal traffic order.
