"Tachograph"Now it is for private car owners have already nothing fresh stuff, which was forced in the early years of digital camera equipment long distance trucks, construction vehicles and buses installed in 2011 in Nantong, Jiangsu together because the old lady bus driver blackmail case and "became a hit," - and then the other, together known as "Tianjin Peng Yu case," the owner of Xu Yunhe deep compared to "Rashomon" fair hearing of the situation, Nantong bus driver Yan Hongbin because buses The "Tachograph"Shooting the video, almost for the first time will be framed lady on his clean, proved himself to be a good person to get off assistance.
Since then, the original unknown niche automotive electronic products many owners in mind what has become the "anti Pengci", "anti-framed" and "artifact", many businesses quickly smell a business opportunity, just two years time. "Tachograph"From the market, only two or three brands, explosive growth and now more than two dozen brands of fish heads mixed products also allow the industry to become disordered, many owners buy fooled by sellers too foggy, but in fact it is not clear if the encounter after a traffic accident, this little thing recorded video in the end to how to use.
Not a "black box"
Many sellers prefer to market sales of tachograph literally called "car black box", but in fact, it is entirely in the confusing concept.
In other countries, "tachograph" refers CAR EDR (Event Data Recorder, accident data recorder), the first tray typeTachographIn 1923 in Germany Feilin roots - poetry 凯茨勒 Ms Donegan city development and production company, usually installed in the back of the car dashboard, on the vehicle speed, time, mileage and vehicle operating conditions and driver driving activity information in real-time recording, can curb fatigue driving, speeding and other serious traffic violations, driver restraint bad driving behavior, prevention of road traffic accidents, traffic safety protection, improve operational management and many other aspects play an important role, and provide raw data for accident analysis and identification.
In 1953, the German government began to load more than seven tons of trucks and buses mandatory CAR EDR. Beginning in 1970, the predecessor of the European Union, "European Community" began to promote the German experience, mandatory in other European countries. 1997, digital CAR EDR put into use in large quantities beginning in 2003, the EU issued new regulations: Since August 2004, registered commercial vehicles over 3.5 tons more than in the EU, with more than eight passenger manned force the installation to use IC card technology, digital printing capabilities CAR EDR. In the United States, Brazil and other countries, if not installed CAR EDR commercial vehicles can not be used on public roads.
According to the German veteran automotive electronics manufacturers VDO (Vereinigte DEUTA-Ota) of a product bid data show that China since 2003, it has been for the CAR EDR technology standards, in 2005 began to force in commercial vehicles, the coach installation.
Be genuine "car black box" CAR EDR private car owners who are not familiar with the "tachograph." Now in the Auto Parts City, Taobao selling "Tachograph"In fact, in a foreign country is known asCAR DVR(Digital Video Recorder, digital camera recorder), its function is relatively simple, but the driving process for video, voice recording, and not as a series of vehicle traveling data recorded as CAR EDR. Many production, salesCAR DVRBoth companies deliberately use "Tachograph"The word to mistaken identity, confused, nothing but the starting point is to show the history of the product of reliable, robust use and borrow" Many European countries forced to install "gimmick to trick owners purchase.
Many attentive owners seen on the network by a large number of Russian drivers 'tachograph' record of accident and driving knowledge, thinking that Russia mandatory installationCAR DVR. But according to some students in Russia's introduction, Russia installation "Tachograph"The private cars are relatively concentrated in big cities like Moscow, because Russia's transportation infrastructure is relatively weak, the crossroads is usually no camera, and even traffic lights are not. High rate of drunk driving Russians, so accidents are mostly owners of their own needs provide evidence for police, tachograph has become the best choice.
Of course, a qualifiedCAR DVRIt is not a simple "camera", the relative household DV,CAR DVRMore demanding work environment (such as a vehicle bumps, startup shutdown voltage is more stable, the summer should exposure), running longer, camera angles greater. A site in 3C products serving test editor, said he never recommend a friend to buy a 1,000 yuan "tachograph" because the price "only camera" and would not have fit the screen recording vehicle products.
"Pengci" new evidence
From New Year's Day 2011, with Beijing as the representative of many Chinese cities are required to medium-sized passenger cars (including long-distance buses and tour buses) must be equipped with the required car recorder (ieCAR DVR, The same below), it is this "traffic Deal" so kindly rescue escaped unharmed after Yan Hongbin, a blessing in disguise to become a certain brand of "tachograph" the spokesperson, but also to many owners believe thatTachographThe video will be their deal with "Pengci children" and in the event of an accident direct evidence.
But so far, the majority of the tachograph users are also some good wishes granted, news reports or from visible to traffic police in different parts of the inquiry results, tachograph video recording can become a "direct evidence "As the market all kinds of"Tachograph"Products, the lack of a" unified standard "do not even look at the video tachograph handling traffic accidents in some areas.
A traffic police in Dongguan, Guangdong, said the tachograph is certainly conducive to accidents finds that: "After a lot of traffic accidents, in order to arrive at the scene later in the exploration of the traffic police can only grasp the collision traces of fallout after collision Indirect evidence trajectory, according to those responsible for the accident judgments made by circumstantial evidence, to tell the truth and can not guarantee a hundred percent correct, especially sometimes, after a vehicle accident has been moved again, to do a more accurate judgment will be relatively difficult a large number. If the car has tachograph, just tune out the video to see, at a glance you can say, no one can deny. "
However, "in favor of a traffic accident identified" and not the same as the concept of direct evidence, there had handled accident litigation lawyer stressed that as the video very easy to edit, the General Civil Justice is not giving admissible, taken with the tachograph If you want to use as evidence material must be identified through the public security and judicial after the "complete, original, no clip" video.
Technically, a lot of "tachograph" In order to achieve the effect of "loop recording", and in working condition will be divided into many small pieces of video recording, video recording at the time of partition, there is often "lost seconds" of the consequences, just This point of view, it is difficult to achieve "complete" requirements.
Currently on the market tachograph products caught, the lack of uniform standards. A website will ever Twenty 3C products priced several hundred dollars to one thousand dollars from the tachograph done horizontal contrast, the question piles: Many products are "vacuity" in the pixel and resolution, so-called " 1080P "or even just" 720P "; some products in order to save costs, with only a low-speed memory cards, often because of work overheat and crash; some ill-considered in the design of brand-name products, minus 10 degrees Celsius can not start the vehicle; a price of thousands of South Korean imports even as domestic brands shooting a few hundred dollars of product; and almost all of the products in night vision test results and advertising photos are a far cry from the imaging results in a product to Toyota Prado SUV, beat out more like a BMW too vague X5.
In addition to the products in question, improper installation tachograph also often lay hidden for their cars. Apart from a few to take power on the current wireless tachograph, most products are circuit cable to the 12V cigarette lighter socket, because many models will be designed to be concealed cigarette lighter, car owners often can not stand the way the power cable mess some people choose to pry open the vehicle roof and A-pillars wires buried, while others choose to pry open the windshield directly behind the center of the reading light, the tachograph power "stitching" on the reading lamp circuit, both for vehicles buried spontaneous combustion risk, but also for insurance companies to provide a pretext deductible.
