Many car owners are often worried that they are often not fuel costs and car supplies, but the fines that cannot be paid, let alone deducting points.In order to avoid your speed, with an electronic dog, it has become the basic car equipment and facilities!So how should we choose an electronic dog?Lets take a look with Xiaobian below!
What is an electronic dog
Electronic dogs, also known as driving safety early warning instruments, are a vehicle device, consisting of hardware systems and software systems, including radar, GPS positioning, central processor, and intelligent speed measurement early warning system.It is mainly to use GPS satellite positioning and radar signal retrieval to remind car owners in advance the existence of speed measuring equipment such as electronic eyes or speed radar to prevent fined and deducting points due to illegal regulations such as speeding.
Can an electronic dog avoid the speed meter?
Electronic dogs mainly provide a function of safety warning, to remind you not to violate the regulations.Of course, you can also remind you where there is speed measurement when you are speeding.In summary, it is indeed useful, but no electronic dog can early warning speed measurement.Because the domestic speed measuring instrument mainly includes radar speed measuring instruments (more use), video speed measuring instrument, floor -to -ground induction ring detection (high accuracy rate is not easy to detect but easily affected by temperature, replacement of maintenance trouble) and laser speed measuring meter (high accuracy is small)These types.Generally, electronic dogs are mainly designed for radar. There are not much way for other types of other types.In addition, the radar speed measuring meter can sensorize the frequency band, so sometimes it will fail, so safe driving is the last word.
Electronic dog purchase
1. Types
For example, friends in the city in large cities should choose electronic dogs that can identify fixed speed measurement, cars that often drive on high -speed roads mainly choose electronic dogs that can identify flow speed measurement, and also consider the problem of radar frequency bands.Go to the purchase conditions.
2. Materials
Many electronic dogs are not well heat dissipated, the radiation is not good, and the cause of the often crashes has a lot to do with the material. This factor is just ignored by riders.
3, appearance
Many electronic dogs have a beautiful appearance on the field, but the key to the purchase of electronic dogs depends on the effect. When choosing the appearance, it is necessary to consider whether the appearance will affect the microwave resonance of the electronic dog. This indicator will directly affect the accuracy of the electronic dog.
4. Function
Electronic dogs are used to predict speed measurement and violation information. Other skills such as: multiple warning reminders, automatic cloud upgrades, color screen types, etc. can also be considered, but single -function electronic dogs are professional than multi -functional integrated electronic dogs.
5, sensitivity
The sensitivity of the radar detector is not as higher as possible, and the error rate is required.Because there are many microwave signals around, as the sensitivity increases, the rate of misunderstanding will also increase.It is more important to choose an electronic dog that can automatically identify other interference signals.
6. Data
The number, accuracy and update speed of the fixed speed measurement database of electronic dogs are the basis of safety warning. Otherwise, no matter how advanced technology is, it is an air attic.
7. Price
The prices of electronic dogs are uneven. There are machines from 200-7000. The more expensive the better, but the cheaper, the better. This principle is similar to choosing a car, and you have to choose according to your own needs.
8. Brand
Any product will involve after -sales service such as maintenance. Compared to miscellaneous brands, big brands are the most assured choices. From the quality of the product to the brands service, users can guarantee it. Once a problem occurs, it can be solved for you.
