The traffic lights, the camera, the distance
The traffic light camera could shoot up to 500 meters and had a special angle setting. In some places, multiple cameras installed in the same direction could see further. Electronic police cameras (commonly found at regular traffic lights or places with heavy traffic) generally had a shooting distance of 50 to 60 meters; Speed cameras (usually located next to speed limit signs, mostly installed on roads with good road conditions or highway sections) had a testing distance of about 300 meters and a photo shooting distance of about 60 meters; Ball cameras (mostly installed on main roads, hospital entrances, and other places where parking was prohibited) had a shooting distance of about 200 meters.

Distance from the camera lights
In photography, the distance of the camera light was related to many factors. First of all, from the perspective of exposure, the distance between the flash and the subject has an inverse square relationship with the exposure. That is, the closer the light source is to the subject, the higher the actual effective exposure value and exposure brightness received by the subject. The farther the light source is from the subject, the lower the actual effective exposure value received by the subject. Secondly, in terms of the hardness of the light, the closer the light source was to the main body, the larger the area of the light source relative to the main body, and the soft light could be obtained (the shadow transition was uniform, and the shadow was light). When the light source was further away from the main body, the area of the light source relative to the main body would become smaller, and the light obtained would be more rigid (the shadow transition was sharp, and the shadow was strong). In addition, many people had a misconception that the farther the light source was, the softer the light would be. In fact, this was not the case. The contrast would become lower when the light source was far away, giving people the illusion that the light was softer. Through experimental comparison, it could be found that the shadow edge produced by a distant light source might be clearer than the shadow edge produced by a close light source. The hardness of the light and the contrast were different concepts. One had to learn to observe the shadow to control the distance of the light to achieve the desired effect. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

How does a Nikon camera capture flashing traffic lights?
The traffic lights are round and square. Can the camera take pictures?
If it was a circular camera, it might be a parking violation camera. This kind of camera was mainly installed in urban areas where parking was prohibited or high-speed roads where getting on and off were prohibited. It could capture traffic in the opposite direction, illegal lane changes, and so on. It had a zooming function and could generally shoot at least 200 meters away. If it was a square camera, it might be an electronic police, which was usually installed at an intersection. It would capture the rear of the vehicle to monitor red light running, driving without direction, illegal lane changing, line pressing, reversing, and illegal activities such as motor vehicles occupying non-motor vehicle lanes. It would not give any prompts when capturing the video. It could also be a traffic monitoring camera, which was usually installed on the pole of the electronic police or the pole of the signal light. It was used to count the traffic flow and provide data support for the signal. It would not capture any violation. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The traffic lights, the cameras, no flashing lights
There might be the following reasons why the traffic light camera did not flash: First, the lighting conditions were better. They could obtain clear images without flashing lights to identify whether the vehicle was running red lights, speeding, or parking illegally. The second was that the camera principle used an induction coil to sense the pressure of the vehicle. There was no need to use flashing lights to trigger the camera. The signal was collected by the sensor and sent to the central processor. The collected information would be sent to the register for temporary storage. The information was valid during the red light. If the car generated two signals at the same time and distance, the red light would be considered valid. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Can the camera still take pictures when the traffic lights are out of power?
The traffic light camera couldn't take pictures when there was no power, because the camera needed power to work properly. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
If there are cameras at the traffic lights, will they be photographed?
Not necessarily. Although the cameras at the traffic lights could be used to capture traffic violation and other behaviors, not all cameras would be photographed. There was a certain trigger mechanism for the camera to take pictures. For example, the electronic eye used a sensing line to sense the pressure from the car on the road. During the red light cycle, the front wheel would produce a pulse when it crossed the line, and the rear wheel would only produce a pulse when it did not cross the line. If two consecutive pulses were not produced, no pictures would be taken. If the front wheel crossed the line and reversed, a pair of pulse signals (in the same red light cycle) would be taken. Moreover, some cameras had specific functions. For example, traffic monitoring cameras were installed on the poles of electronic police or signal lights. They were used to count traffic flow and provide data support for signals. They would not capture any violation. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The traffic lights, the cameras, the flashes
The flashing of the traffic light camera was mainly used to ensure the clarity of the picture in the case of insufficient light (such as night or rainy weather), so that the relevant information of the vehicle (such as license plate number, etc.) could be accurately captured. This principle was similar to the working principle of the electronic eye. The electronic eye system was mainly composed of a high-definition camera, an image processing computer, and an alarm device. When the lighting conditions were poor, it was difficult for the camera to capture a clear image for the computer to accurately read the vehicle's speed, model, body color, license plate number, and other information. Therefore, it was necessary to activate the flash to fill the light. When the vehicle passed the surveillance range of the camera, the system would automatically trigger the flash when it detected that the image signal was below the standard. Moreover, the red light camera would flash and take three photos, which could accurately record the behavior of a motor vehicle running a red light. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Teaching plan of traffic lights in kindergarten
The following is a kindergarten traffic light lesson plan: ##1. Teaching objectives 1. Let the children understand that they must abide by the traffic rules when crossing the road and enhance their safety awareness. 2. Cultivate children's habit of obeying discipline, so that children can grasp the basic knowledge of traffic safety and improve their self-protection ability. 3. To guide children to abide by the rules of social behavior and not to do anything against the rules. 4. Arouse children's interest in exploring the variety and characteristics of life. ##2. Teaching preparation 1. Images of traffic light signs and projections of traffic signs observed by children in their daily lives. 2. A red, green, and yellow traffic light made of cardboard. ##3. Teaching process ###(1) Introduction of the topic 1. Show the traffic safety picture and lead to the topic of "obeying traffic safety rules." 2. Learn about the red, green, and yellow lights together with the child. Through the content of the children's song, let the child know "stop at the red light, go at the green light, stop at the yellow light". ###(2) Explanation of Game Rules and Game Development 1. The children were divided into two groups. One group acted as a small car, and the other group acted as a child walking. It was stipulated that cars and pedestrians must stop when they saw a red light and could only walk when they saw a green light. 2. During the game, the teacher should pay attention to guiding the children to obey the traffic rules. ###(3) Game summary and daily safety knowledge expansion 1. At the end of the game, the teacher and the child would make a summary together, praise and reward the child who abided by the rules, and ask the child to bring this knowledge home to share with his parents. 2. From the activities, other safety matters in daily life were introduced, such as eating slowly, watching the road when walking, and not walking with strangers. In addition, music games could also be used to teach about traffic lights: ##1. Game goal 1. In the traffic light game, try to use various forms to perceive and express the characteristics of the music of "start and stop". 2. Able to react quickly to changes in music. ##2. Game preparation Music and Red Bracers each had one. ##3. Game process ###(1) First Game 1. How to play: All the children sit in a circle and imitate the teacher driving the car with the music. When the music stops, they immediately stop moving. 2. Guiding points and key points: Through body movements, guide children to perceive and discover the characteristics of music that starts repeatedly and stops suddenly. ###(2) Second Game 1. How to play: Group driving with the change of the music. In the first half of the music, the teacher used "Red light, green light, red light immediately" to remind the group to sit to the right and change seats, step on the brakes, and ask to park the car well, otherwise they will be fined by the traffic police. 2. The main points and key points of the instructions: When the phrase stops, quickly react to shift to the right, brake, and control your body to stay still. ###(3) Third Game 1. Play method: collectively stand on the point of the circle in the counterclockwise direction, and do the twisting car action according to the change of the music. In the first half of the music, the teacher will use "red light green light, red light immediately" to remind the children to quickly react and move forward to brake (park their car in front of the parking space). At the end of the music, guide the children to make different parking poses and control their bodies. Otherwise, they would be fined by the traffic police uncle. 2. The key points of guidance: Quickly react and change positions to stop the car before the music stops. At the end of the music, you can make different poses and control your body. ###(4) The fourth game 1. How to play: Two children stand face to face on the points of the circle and drive the car according to the changes of the music. When they hear "red light, green light, red light immediately", the young driver quickly reacted and held his right hand to exchange parking spaces. Finally, when the music came to an end, he guided the child to stand on a chair and pose in a different parking pose. 2. The main points and key points of the instruction: Quickly react and change parking spaces in pairs before the music stops. At the end of the music, stand on the chair and pose differently to stabilize the body. ###(5) The fifth game 1. [How to play: Turn into a train and drive freely with the music. When you hear "Red light, green light, red light is coming soon", you will collectively brake and say goodbye to everyone before leaving the activity room.] 2. The guiding point and key point: brake when the phrase stops and say goodbye to everyone. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
