Interpretation of the four classification of electronic dog

Now we usually used in car anti-speeding electronic dog is divided into four main categories: embedded electronic dog, radar electronic dog, GPS stand-alone electronic dog, and GPS radar electronic dog. Below its features one by one!

    This device first point I want to tell you is that it is only illegal equipment in the four electronic dog we mentioned earlier. Because it is not just the received signal and transmitted signal, which is in violation of China's Radio Regulations. Embedded electronic dog navigator prices between 50-300 yuan into the cigarette lighter. It alarm electronic eye principle is very simple: producing embedded style electronic dog manufacturer in the electronic eye, stealing possession of a radio transmitter, it is for where the line's features, hair a containing information code radio signal car opened near here receiver receives a radio signal transmitter and decoding the type of alarm, sound chip, a voice alarm, so the speed limit, this section one-way electronic eye in this intersection.

    · First: This product can not deal with mobile speed car velocimetry in high-speed, almost useless.

    • Second: Most of this product in Shenzhen, Shenzhen is now almost all the traffic lights are fitted with the electronic eye, therefore, electronic dog will be ringing off the hook, not only lose their significance to the alarm, but also very noisy, the volume of products in general can not be adjusted , can not be closed;

    • Third: approved by the Radio Authority, set up such a transmitter is illegal, but also power supply, the need to secretly changing, may be removed or damaged.

    Fourth: the transmit power of the transmitter properly, such as the received signal when it was too late; too large and far started calling and annoying.

    Need to note: this product in major cities such as Shanghai, Shenzhen has a large number of sales, if you are not in local use, please do not buy. This electronic dog signal transmitter only in a particular city to other places this device completely lost meaning.

    Radar electronic dog very simple principle, to the radar signal is received, immediately after the alarm, suggesting that the owners of deceleration. Radar electronic dog most of the imports, the price usually ranging from 800-5000 yuan, the level of performance is also very different. Such as the different products of different brands and models, can receive the radar band. Our urban road radar speed measurement equipment from different countries of imports, as well as our own production, the use of radar frequency is not the same, the same city, some installed three or four different band radar gun. Low-end radar detectors often can sense a two-band radar products, Main products: car dvd player and car dvd , are with good quality.such as Japan), and high-end radar detectors, radar can sense more than one band, and even a laser sensor, but also can The anti-laser gun, so to buy a full range of radar electronic dog should be a minimum requirement. In addition, the radar signal detection distance distance also reflects the performance level of the radar electronic dog. Such as the detection distance is too close to the owners too late to slow down, has been photographed; such as slow down too much, could easily lead to rear-end accident. Positive general high-end radar detectors can be about one kilometer to detect radar, while the poor only about 200 m can be detected.
