The Big Revelation of Electronic Eye Snapshots: Friends with cars can come and take a look, it's practical... Nowadays, electronic eyes are set up in many places. Seeing one violation notice after another for both public and private vehicles from the company is truly frustrating. I recently learned some methods to avoid electronic eyes from a netizen and decided to share them with all my colleagues for reference. Wishing everyone a safe journey!
The violation photos taken by the electronic eye are stored on a memory card under the device, which is collected every three days. It is outsourced to a certain company, where the photos are first sent for checking if there is sufficient evidence of violations (three photos must be complete to fully prove). Then they are submitted to the traffic management bureau.
First trick: Notice that at intersections with electronic eyes, there are diamond-shaped grooves both before and after the warning line. These contain buried induction coils. But remember, the electronic eye only activates three seconds after the red light comes on! Also, if you drive over the line and the first photo is taken, whether it's the front or rear wheel crossing the line, do not move! If you move, it will trigger the coil again and take a second photo! Three photos are needed for it to be valid. The rules for photo evidence collection are as follows. Generally, the evidence photos are like this:
- The first photo is when the front wheel crosses the warning line.
- The second photo is when the rear wheel crosses the warning line.
- The third photo is when you cross the warning line on the opposite side of the intersection.
Only when these three photos are complete can they be submitted to the police, and then you will receive a fine notice. Haha, 200 yuan.
So, if your front wheel crosses the line, it's okay. The first photo being taken doesn't matter as long as you don't move, because moving would trigger the second photo. Even if you move and the second photo shows your rear wheel crossing the line, it's not a big deal as long as you don't cross the intersection or stop beyond the warning line on the opposite side. Coming back to the point, if your front wheel was photographed in the first photo, some people might think about reversing a bit, but that's wrong. Reversing would trigger another photo! Haha!
Second trick: Have you noticed the small dot behind the first letter of your license plate? This small dot is made of rare earth metal and embedded for the purpose of focusing the electronic eye! This is a global standard for license plate production proposed by Japan's Sony Corporation! Therefore, those driving Chinese cars shouldn't criticize Japan, as there's at least one thing on your car that uses Japanese technology! An insider revealed that this small piece made of rare earth metal produces weak microwave signals under light induction, which helps the electronic eye capture images. What should you do? It's simple. Remove it carefully and keep it safe. When it's time for vehicle inspection, stick it back on with double-sided tape, and remove it afterward. Hehe! No matter how much the electronic eye tries to photograph, it won't be able to clearly capture your license plate number. Is it "0" or "8"? Haha! A lot of police officers don't even know this! Police explanations often cover only half of it, as it also serves to prevent forgery.
Revelation of the working principle of electronic police:
1. The electronic eye uses induction lines to sense the pressure transmitted by cars on the road. The sensor collects the signal and sends it to the X processor for investment management, temporarily stored in the register (this data is valid within one red light cycle);
2. Within the same time interval (red light cycle), if two pulse signals are generated simultaneously, it is considered "valid." Simply put, if the red light is on, your front wheel crosses the line while the rear wheel hasn't yet crossed, only one pulse is generated. Without two consecutive pulses, no photo is taken;
3. In some cases, some people drive their front wheels over the line and fear being photographed, so they reverse back into the line, but still get photographed. Why? Because a "pair" of pulse signals (this pair is produced within the same red light cycle) is generated. I've been photographed multiple times due to this, ###;
4. When the yellow light is on, the camera system delays activation by 2 seconds; when the red light is on, the system has already activated; when the green light is about to turn on, the system shuts down 2 seconds early, mainly to prevent accidental shots. That's why many taxi drivers know that they can start driving without issue, based on this principle. However, I suggest everyone not to do this because it's hard to time correctly.
Post-processing:
After the images are downloaded and transmitted to the command center, they need to be registered, numbered, announced, and then transmitted to the central computer database for various agencies to use.
System features:
Vehicle capture rate ----- 100% (excluding motorcycles, etc.)
Recognition time ----- about 1 second (definitely faster than your reaction).
License plate recognition rate ----- more than 95% during the day, more than 90% at night (quite high).
Applicable vehicle speed ----- 5-180 km/h (if you're driving at 190 km/h in the city, you can escape easily).
