Relevant departments are taking action against the "brightening" surveillance fill-in light! Does it really work?

Driving at night, "high-beam dogs" disgust us. But they never expected that those flashing surveillance lights that could not be avoided on the road would make car owners even more miserable.

01

The "blinding" surveillance light has become a safety hazard

Recently, a netizen reported to the traffic police online. Because of the blinding glare of the surveillance lights, he could not see the pedestrians crossing the road in front of him, which almost caused a disaster. Fortunately, both sides avoided it at the last moment. But the dangerous process is still scary.

As for the topic "Does the surveillance fill-in light affect safe driving?", the People's Daily conducted a small survey: 83,000 of them thought it seriously affected driving, especially when driving at night.

According to statistics from the Ministry of Public Security, 30% to 40% of traffic accidents that occur at night are related to the misuse of high beam lights, and the trend is on the rise. This also fully illustrates the impact of glare on night driving. harm. The bright light is more powerful than the tiger, and the fill light seems to be brighter than the high beam. The degree of danger cannot be ignored.

Why not dismantle "Bright Eyes"? What's the use?

As an auxiliary light source in night vision monitoring, the surveillance fill light can capture passing vehicle information, investigate traffic violations, and provide timely traffic hit-and-run, public security, and criminal case updates when the natural light source is insufficient at night. Clues and analysis of road traffic flow all play a significant auxiliary role.

The "General Technical Specifications for Imaging Fill-in Light Devices for Traffic Technology Surveillance" stipulates:

Under the rated voltage, the power consumption of the fill-in light device should be less than or equal to 50W per lane; The fill light area formed on the road surface should cover the monitoring imaging area of ??the traffic technology monitoring equipment, with uniform illumination, no obvious dark areas, and must not have an impact on the surrounding environment.

Why do high-definition cameras need fill light? The surveillance camera needs to capture the car's license plate, body color, and overall vehicle condition. The camera is more than 20 meters above the ground. Some road sections have weak light at night, so fill-in light is needed to capture a clearer picture.

Does the monitoring fill light affect driving safety?

"It must not have any impact on the surrounding environment." So, are the current surveillance fill lights qualified?

According to relevant manufacturers, surveillance fill lights are divided into three categories: strobe, constant light (to assist license plate recognition), and flash (flashes when passing a car to assist driver identification).

The power of the always-on monitoring fill light is generally 20 watts, while the power of the flash monitoring fill light can reach 200 watts in an instant, which will cause blind spots in the driver's eyes.

Every driver who has experience driving at night knows that being exposed to strong light will cause the driver's eyes to be temporarily "blind". Although a short period of strong light will not cause substantial damage to the human eye, .

However, at night or in a dim environment, the dazzling lights will cause discomfort to the eyes, making it impossible to distinguish the road conditions. The car is basically in a "unmanned driving" state, which is a problem for drivers who drive at night. He said that there would indeed be certain security risks. For this reason, the glare of "strong light" has become one of the most troublesome situations for drivers!

What is the response from various places to the phenomenon of "brightening the eyes" with fill lights?

The phenomenon of surveillance lights "blinding one's eyes" is no longer a matter of a day or two. People in various places have reported it. Let's see how the relevant departments respond.

Beijing: Dim the brightness

Xiamen: Adjust the organizational investigation

Shaoyang: Turn on the fill light in time periods

The topic of "surveillance fill-in lights are too dazzling, causing great hidden dangers to night driving safety" has always attracted much attention. After continuous feedback from the public, relevant departments have also made adjustments to this, but these adjustments still "treat the symptoms rather than the root cause." "Many car owners still report that the fill light is blinding."

Written at the end

As an auxiliary light source for road monitoring, we understand and do not object to the fact that fill lights are indispensable at night.

However, judging from the current situation, it is true that the fill lights on some road sections are too bright, affecting drivers' night driving. Is there a contradiction between the "no impact on the surrounding environment" in the regulations and the visual blind spots reported by the public? Sacrificing safety to ensure traffic order, is this "safety account" really a good deal?

We hope that relevant departments across the country can, in order to ensure the recognition rate, do a good job in investigating and optimizing the monitoring fill lights, reduce safety hazards, nip them in the bud, and ensure the driving safety of the majority of drivers. Safety.
