The LED monitor light "light pollution" that has been criticized has been saved.
Recently, Wenling Daily reported a news about "the skylight project's fill light is too bright and the public complained about the response." The phenomenon of light pollution and disturbance caused by video surveillance fill light is not the first time. In the intelligent transportation field, the fill light is an indispensable key equipment. At present, the video surveillance fill light equipment has two kinds of LED flash and LED constant light. In this news, the public complains about the nighttime lighting. LEDs are always on, and LED flashes, which are commonly used in traffic jams, are frequently criticized by many drivers for their frequent flicker and high-brightness illumination. 
Filling device technical standards released
On October 24, 2014, the Ministry of Public Security released the GA/T1202-2014 "General Technical Conditions for Traffic Technology Monitoring Imaging Filling Device" for the first time. The standard specifies the traffic technology monitoring imaging fill light device and technical requirements, test methods, setting requirements and inspection. Rules, etc. The release of the "General Technical Conditions for Traffic Technology Monitoring Imaging Filling Devices" is necessary, because if the fill light used in intelligent transportation and monitoring does not have a unified standard, it will breed many problems for the whole industry. Inconsistent, the scope of use is inconsistent, the angle and the interface used are different, which may affect the versatility of the product. The customer will have great defects in the process of use, selection and use cost. Once the standard is released, It can directly drive the development of the industry towards standardization, industrialization and scale.
However, although the standard gives a hard reference value, due to the different research and development strength and technology of the manufacturer, as well as the influence of the use environment and angle factors, there are differences in the actual use effect of the LED fill light .
The lighting of the monitoring equipment of the public reaction is too bright to affect the rest. The Hangzhou Public Security Bureau said that the brightness of the fill light of the Skynet project video surveillance installed in the city is set according to the relevant standards for monitoring. The brightness of the fill light directly affects the video recording and capture effect, and the road monitoring at the entrance of Wanchang Road Unicom belongs to the town-level bayonet that is handed over between Chengdong Street and Taiping Street. The point is very important and must be guaranteed. effect. Considering that the fill light is too bright for residents' driving and life, the construction team has been notified to reduce the brightness of the fill light by 30%, and try to meet the residents' living requirements without affecting the video recording and vehicle capture. Decrease the brightness of the light, which is the way to handle the LEDs.
Manufacturers move to eliminate "light pollution"
For the driver's complaints about the "flashing" LED flash, currently, in the security field, Kodak, which specializes in intelligent transportation solutions, has developed a "light" electronic police series dedicated to solving the problem of light pollution caused by fill light. The products are on display at the annual Intelligent Transportation Exhibition.
According to statistics, in recent years, traffic accidents caused by flashing lights flashing the driver's line of sight have increased at a rate of 12% per year, which is enough to attract the attention of urban traffic management departments. As a practitioner of green transportation, Kodak has developed a series of “light†electronic police products for urban traffic light pollution problems, which can capture HD violations without any light filling. Secondly, the intelligent flashlight and LED fill light developed by Keda's four-in-one electronic police system use precise control circuit to achieve high-energy flash in a very short time, and 100% synchronization with the camera. It uses a patented technology shading device to eliminate ineffective illuminance, reduce light pollution, and greatly reduce the impact of the fill light on the driver. At the same time, it can also adapt to the lighting conditions of different environments, the power is continuously adjustable, and it can also save energy and protect the environment while at the same time ensuring the effect.
When talking about how the self-developed fill light of Kodak realized the image quality of the captured image while avoiding light pollution, Xu Guoming, marketing director of Keda Intelligent Transportation Industry explained: “The cause of the eye-catching is the brightness of the light source* flash At the time, when the human eye looks directly at the light source, the pupil will shrink. Once the light source disappears, the human eye will appear a short glare, which is the main cause of such traffic accidents. However, if the brightness and flash time of the lamp are controlled In a certain range, to ensure that the brightness * flash time is less than a certain value, you can avoid the glare of the owner, thus reducing the occurrence of traffic accidents. Kodak's flash power is 36J, flash time is 0.3 milliseconds, and most flash on the market The power is 200J, the flash time is up to 3 milliseconds, and the brightness and flash time are ten times that of Kodak products. In addition, other security manufacturers generally have their own monitoring series, but in the case of traffic monitoring, Some manufacturers do not produce lights, but directly use the lights on the market, which can not guarantee the between the camera and the fill light.
LED fill light is a key device for video surveillance equipment to capture high-definition images and videos, and plays an indispensable role in the collection of intelligent traffic front-end information. An excellent product not only conforms to the general technology and standards of the industry, but also maximizes the functions and functions, and also avoids the negative effects that the equipment may bring during use, providing users with a good experience.
