A detailed breakdown of how traffic cameras work; those who own cars can come and take a look

A detailed breakdown of traffic camera footage taken from the internet; those who own cars can take a look, it’s useful. . . There are two versions below; which one is correct? Let’s all discuss it. Nowadays, traffic cameras are installed in many places, and it’s really frustrating to see company vehicles and personal cars receiving violation tickets one after another. I happened to come across a tip from an internet user on how to avoid traffic cameras, so I’m sharing it with all my colleagues. For reference. Wish everyone a safe journey! The photos of traffic violations taken by the traffic cameras are stored on a memory card inside the camera, and they can be retrieved every 3 days. It is outsourced to a company; the photos are first sent to that company to determine whether there is sufficient evidence of violations (three photos are required to have a complete set of documents), and then they are submitted to the traffic management bureau. First trick: Take a close look; at intersections equipped with traffic cameras, there are diamond-shaped grooves dug in front of and behind the barriers, and it is within these grooves that the induction coils are placed. But remember, the camera only activates three seconds after the red light turns on! Also, when driving and you cross the line, take the first photo; whether it’s the front wheels or the rear wheels that cross the line, don’t move at all – definitely don’t move, as any movement will trigger the sensor to take a second photo! Three are required to be valid; that’s the rule for taking photographic evidence. Typical evidence photos are as follows: the first shows the front wheel crossing the barrier, the second shows the rear wheel crossing the barrier, and the third shows you crossing the barrier at the opposite intersection. All three photos are required in order to submit them to the police, who will then issue you a fine notice. Hehe, 200. So, it doesn’t matter if your front wheel goes over the line; it’s fine if the first photo is taken. As long as you don’t move, no second photo will be taken. If you do move and that triggers the second photo, with your rear wheel also going over the line, it’s not a big deal either – you just don’t need to cross the intersection, or you can stop outside the warning lines on the opposite side of the intersection! Anyway, just now when your first front wheel was illuminated, some people might have thought it would be fine to move back a bit. But that’s wrong – by moving back, another image is triggered! Hehe! Second trick: You don’t see the little dot behind the first letter on your license plate! These small dots are made of rare earth metals and are used for fitting onto the cameras; their purpose is to help the cameras focus! License production standards around the world, ha! Which element should be used for inlaying was proposed by the Japanese company Sony! So, those who drive Chinese cars, stop blaming Japan – there’s at least one component in your cars that is of Japanese origin! According to insiders, this small component is made of rare earth metals, and it generates weak microwave signals that can be detected by cameras when exposed to light. How to do it? It’s simple: remove her and keep her safely, then stick her back on with double-sided tape during the vehicle inspection, and remove it again after the inspection. Hehe! The camera can’t capture your license plate number clearly no matter how you try. Is it “0” or “8”, haha! Many police officers don’t even know about these things! The explanations provided by the police are often only half true; preventing forgery is also one of its functions. Unveiling the working principle of electronic traffic police systems: 1. Traffic cameras use sensors to detect the pressure exerted by cars on the road surface; the signals are collected by sensors and sent to an X processor, where they are stored temporarily in registers (these data remain valid for one red light cycle) ; 2. Within the same time interval (the red light cycle), if two pulse signals are generated simultaneously, it is considered \"valid\". In simple terms, if the light is red at that moment and your front wheel has crossed the line while your rear wheel has not yet done so, only one pulse is generated; no photo is taken in the absence of two consecutive pulses ; 3. In some cases, a person drives with the front wheels over the line; fearing being caught, they reverse the car back into the line, only to still be photographed. Why is that? It is because of the sequence one after another that a \"pair\" of pulse signals is generated (this pair of pulses is produced within the same red light cycle), and that’s why I was queued n times### ; 4. When the yellow light is on, the photography system starts after a 2-second delay ; When the red light is on, the system has already started ; The system is turned off 2 seconds before the green light turns on, mainly to prevent accidental recordings. So many taxi drivers know that it’s almost time to leave; it’s the same principle – if nothing goes wrong, then it’s fine. But it is advised not to do this, as it’s quite difficult to get the timing right. Post-processing: After the image is downloaded and transmitted to the command center, it needs to be registered, numbered, and announced before being sent to the center’s computer database for use by various agencies. System features: Vehicle capture rate ----- 100% (excluding two-wheeled motorcycles, etc.). Recognition time-----about 1 second (definitely much faster than your reaction time). License plate recognition rate-----over 95% during the day, over 90% at night (quite high). Applicable speed------5-180 km/h (If you’re driving at 190 km/h in the city, you can just drive away right away. http://a3.att.hudong.com/31/45/01300000165486121695454575438.jpg)

Hehe, the incident related to breast touching in Chengdu was exactly about this. Friends on our chemical engineering forum who own cars should take their girlfriends out in the car, but please avoid having sexual intercourse inside the car

I’ll come and see when I have money

Reply to 3# ray1513: The two versions are different; which one is correct?

I haven’t bought a car yet; I need to learn first. No matter which version is correct, it’s better to use both approaches. We won’t be able to carry out your last tactic.

I’ve seen it before; in fact, in Tianjin, the cameras at intersections are mainly used for road surveillance. As for taking photos, generally there’s not much of a problem with running red lights. But now many intersections are equipped with cameras to capture violations, so there’s nothing that can be done. Actually, all of these issues are easy to handle; what’s really scary is having traffic police hiding inside cars. I guess that’s how all my traffic violations came about, sigh
