New variables in the security industry: Plunging Illuminance, Concept Competition, AI Racing, Exciting
"Starlight", "Black Light", "AI Ultra-light", "Aurora" What is the magic of low-light camera technology? In the five years of steady development of low-light technology, how can Hikivision, Dahua and other security giants and many security guards stir up this market? In 2019, what is the low-light camera that is closely integrated with artificial intelligence and brought to the security industry?
The low-illuminance camera can fill the deadly short board of the security night surveillance industry's "night blind eye" and become one of the hottest technical breakthrough points in the security circle. According to statistics, nearly 70% of crimes occur at night. If many places such as roads, warehouses, and the wild cannot be monitored at night, the personal and financial security of cities and towns will only be in the shadow.
The method of filling light has already existed, but the problems of “light pollution”, “energy waste” and “blind area” have been the pain points of night surveillance.
Since 2014, the newly born "Starlight" has become synonymous with "low illumination" in the security field. Since 2016, low-light cameras have ushered in a high-speed development stage.
From starlight to many varieties of technology, to fill the gap in the eye of security
Starlight cameras came into being. In the usual sense, a star-level camera usually refers to a camera that can display a clear color image without any auxiliary light source in a low-light environment with almost starlight. The so-called star-level illumination is between about 0.01 lux and 0.001 lux, while the sunny, moonlight night illuminance is about 0.1 to 0.01 Lux.
Similarly, "super starlight" and "black light" reduce the illuminance again. Generally speaking, when the illuminance is below 0.001Lux, it is "super starlight", and when the illuminance is 0Lux, it is "black light".
Simply put, the "night vision" of a star-level camera is optimized by multiple hardware dimensions such as lens, aperture, picture sensor and fill light. The lens and aperture limit the ability to transmit light and enter light respectively, while the image sensor passes the sensitizing ability, and the fill light can supplement the low illuminance of the camera by the fill light capability.
At present, low-illumination cameras such as star-level cameras have been widely used in scenes requiring high picture definition in scenes with dark or no light, such as roads, warehouses, fields, farms, communities, factories, etc. For example, in the field of public security, the past cameras can only shoot black and white pictures, but the starlight cameras and even higher-level "black light" and "aurora" cameras can help the police through the color night vision effect to determine "what color clothes the suspect wears." "There are other issues, which greatly reduces the difficulty of solving the case.
In recent years, "Starlight" low-illuminance cameras have changed from concept to standard products of various manufacturers, and more extreme low-light technology such as black light and aurora has become the focus of attention of various manufacturers. From pursuing a lower illumination environment to pursuing a better-looking picture, and pursuing the ultimate clarity and color reproduction to help AI intelligent recognition applications, the development of low-light cameras has been leaping forward.
In the field of low illumination surveillance cameras, traditional security companies have a first-mover advantage. Low illumination monitoring technology involves many technical dimensions, and has certain industry thresholds. Traditional security players with early development and sufficient industry chain resources and channels lead the trend. With the increasing application of AI in the security industry, non-giant security companies use AI algorithm technology to open up new low-light surveillance camera technology paths, and can also show differentiated play, thus dividing the fragmented security market.
The ever-developing low-light surveillance camera technology has enabled the security industry to continue to extend the boundaries of the scene. The 8-hour camera has become a "24" hour working system. Many wilderness fields, factory fish ponds, and deep lane corners that were previously not well monitored are not. In addition to the extraterritorial land, problems such as “light pollution” and “energy waste” are also solved. Although there are many complex scenarios that need to be considered in the application of technology, this fragmented market situation also presents different opportunities for players with many different technical routes.
