Why does the surveillance probe next to the traffic light only flash to take pictures when the car i

Under normal circumstances, it will not flash, and those who are flashed are traffic violations, and only those who run red lights and speed will be flashed. The principle is infrared sensitivity, as long as the car comes into contact with that part of the infrared, it will automatically take pictures. As for why the motorcycle doesn't flash, because there is no infrared sensor in the place where he walks, this is a bit like in the movie, and the alarm goes off when he touches that part.

A dedicated camera for smart computers.

How does e-police work:

Monitoring and shooting: 1. The electronic eye uses the induction line to sense the pressure from the car on the road, and collects the signal through the sensor to the ** processor and sends it to the register for temporary storage (the data is valid in a red light cycle);

2. In the same time interval (red light cycle), if two pulse signals are generated at the same time, it is regarded as "valid", simply put, if the red light is at that time, your head wheel crosses the line, and the rear wheel does not go out, then only one pulse is generated, and when there are no continuous two pulses, do not take pictures;

3. In some cases, the front wheel of the car crossed the line, and I was afraid of being photographed, so I reversed the car and returned to the line, but the result was still photographed. This is because one after the other, a "pair" of pulse signals is generated (this pair of pulses is generated in the same red light cycle);

4. When the yellow light is on, the camera system will be started after a delay of 2s; When the red light is on, the system has been started; When the green light is about to turn on, turn off the system 2s in advance, mainly to prevent false shooting.

System features: vehicle capture rate --100% (excluding two-wheeled motorcycles, etc.).

The recognition time --- about 1 second (definitely much faster than your reaction).

The license plate recognition rate --- more than 95% during the day and more than 90% at night (relatively high).

Applicable speed --5-180km h.

1. The principle of illegal TV capture.

There are two ways, one is to bury the induction coil underground, and the digital camera is erected on the crossbar, is used for the capture of running red light, and the other is to set up camera, is used for speeding speed, running red light, illegal parking and the like to carry out real-time video. Either way, at least three ** will be taken for the illegal vehicle, one is an instant violation**, one is the number plate recognition**, and one is a panorama**. Either way, it's 24-hour shooting, and the retention time is generally one week.

2. Violation handling process.

The command center receives **, will compare the license plate number information with the information of the vehicle management office, so as to call up the comprehensive information of the vehicle, such as the owner, model, color, etc., and then enter it into the Beijing Municipal Public Security Traffic Management Bureau by the information processing personnel, so that the illegal owner can make inquiries.

3. Information loss.

Not all illegal vehicles can be photographed, only when the license plate is clear, the information entry personnel can enter the illegal vehicle into the database for processing.

4. Shooting range:

A camera usually only captures one lane, and a few can shoot two lanes, usually on the first and second lanes counted from left to right. Digital cameras have a wide shooting range, so most of the urban areas can capture all the lanes in the same direction.

The electronic eye uses an induction line to sense the pressure from the car on the road, collects the signal through the sensor to the ** processor, and sends it to the register for temporary storage (the data is valid for one red light cycle).

In the same time interval (red light cycle), if two pulse signals are generated at the same time, it is considered "valid", simply put, if the red light at that time, your head wheel crosses the line, and the rear wheel does not go out, then only one pulse is generated, and when there are no two consecutive pulses, no photo is taken.

The flash is automatic, and it flashes when the ambient light intensity is not reached. If it is daytime, it generally does not flash when the sky is good.

There is no need for flashes during the day. It's the same as taking a photo with a person, and it will flash automatically when the light is low!

Flash is a normal vehicle monitoring photo, if you flash twice, you will be photographed illegally, wait to be fined! "Car Profile" introduces common cameras that can help drive safely! Nowadays, common traffic cameras are divided into the following types, electronic police,Speed camera, traffic monitoring camera, LED fill light, illegal parking capture, Tianyan monitoring!

Explain to you one by one!

Electronic police, we usually deduct points for driver's license are basically its credit, running red lights, not driving according to the prescribed route, pressing the line, motor vehicles are illegal, but there is one point, the electronic police shoot violations are without warning, we can't see, basically within half a month SMS notification violations!

The speeding camera, mainly to monitor the speed of the vehicle, for the speed of more than 10% of the vehicle will be photographed, the general photo is in front of the vehicle, the driver is clear, it is impossible to take someone else's driver's license top bag! This kind of camera is installed on national highways, provincial roads, highways, and urban main roads through radar speed measurement or coil speed measurement!

The traffic monitoring camera, installed on the pole of the signal light, only has the data storage function, analyzes the traffic conditions of each road section, which is conducive to the traffic police to understand the whole process of each road section, and there is no violation capture function!

LED fill light, only turned on at night, not during the day, to put it bluntly, is to increase the brightness of the light around the camera, which helps the traffic camera to take pictures more clearly!

Illegal parking camera, this kind of camera has a zoom function, it can be said that the vehicle can be cleaned within a radius of 100 meters, mainly used to judge whether the vehicle is illegally parked, get on and off the car, whether it is going in the wrong direction, etc.!

Tianyan monitoring, mainly used to monitor major traffic intersections or areas, 24-hour monitoring, does not have the function of shooting violations, only to eliminate potential safety hazards and set up! Most of them are distributed in various intersections, ** areas with large traffic flow, schools, communities, hospitals, and shopping malls!

Traffic cameras are now particularly sensitiveOnce a traffic violation, nine out of nine can't run, for our own walletsFor your own safety, everyone drives cautiously and wishes everyone a safe drive!

Therefore, when you see the electronic eye on the side of the road, you don't have to be nervous at all, because there is no violation of the rules will not be misjudged, even if the traffic police are in **, it is fine, but once you enter the camera picture, any violations will be filmed. And the existence of the camera is not to find violations, so as to deduct points and fines, in fact, the camera mainly plays a warning role, reminding the owner to operate reasonably.

That's for sure, this electronic eye will take a picture of your car and calculate your speed.

Yes, that's a speed camera that calculates the speed of each passing vehicle.

Yes, if the camera is flashing, it means that it has been photographed.

Yes, this is a capture recorder, as long as every move will be filmed.

It was photographed, but it may be just a make-up photo, not necessarily a point deduction.

In general, it may be photographed, because the speed of the vehicle is to be detected.

Yes, this is also called an electronic eye, which is to capture the speed of the car.

This is a capture of the electronic dog, once there is a violation, it will be photographed.

This statement is correct, because the traffic police force has to always detect some violations in the car.

All the cameras installed at the intersection without rotating shafts but flashing are monitored for running red lights, crossing lines, and pressing lines.

These cameras are usually equipped with a flash device and are mounted very close to the camera, in a boxy white cuboid. As long as the line is pressed, the computer will automatically take pictures, and the winning rate will be 100%.

The biggest difference between this type of camera and 360-degree monitoring is that it does not have a rotating axis, and second, it has a noticeable flash device.

The cameras installed on the road are divided into the following five categories and four major functions:

One is road monitoring.

The second is public security monitoring.

The third is the red light monitoring at the intersection.

Fourth, speed monitoring.

Fifth, monitor and collect red lights, cross lines, and press line violations.

Every year, the traffic police brigade will let go of a lot of violations that are not clear, because the evidence must be convincing, otherwise the owner of the car will pay the fine under the pretext of ambiguity, and do not admit it (most people will admit it, but there are always a few strange people who will cheat). In this way, the traffic police will not be able to make up for the violations, because the data has entered the computer library, so the violations can be found, and most of the traffic police are conclusive, quite clear and convincing, I have done it in it, it is very clear. Hope to adopt.

Can't shoot because he doesn't, ** point.

Not necessarily, there is infrared detection.
