HD car recorders Now more and more car owners will be equipped with driving recorders in the car, but different manufacturers of driving recorders have given different solutions, and some solutions consumers can install them themselves, but some programs It can only be done in a professional third-party health agency. What is the difference between these different driving recorders? The following is a summary of the most complete way to take power on the current driving record. Let us know the difference between different ways of taking power.
Driving recorder must be equipped with a voltage regulator
At present, most of the driving recorders are pasted on the front windshield. Because the driving recorder itself is generally not equipped with a power supply and has a small volume, it is in the form of external power supply. The use of the driving recorder must be used with a dedicated voltage regulator, that is, the input power supplied by the manufacturer with a small box at the time of purchase. Some third-party maintenance organizations are habitually not using this power supply line when installing the driving recorder. Later, this method may cause damage to the driving recorder or unstable recording of the image due to the huge current generated when the car is started. . Therefore, if consumers install a driving recorder, they must require the installation manufacturer to use a dedicated power supply line with a voltage regulator.
Battery step-down power supply used in the original driving recorder
Now many models have been equipped with driving recorders. Many consumers will find that the original driving recorders are relatively stable, and the power supply leads are hidden. This is because most of the original factories The driving recorder uses a battery with a dedicated step-down line to work. The advantage of the battery directly taking power is that the driving recorder can achieve 24-hour uninterrupted image recording, and unlike some models, the driving recorder will stop working after the engine is turned off. In addition, the benefits of the battery directly taking power, and the fact that the vehicle does not cause a large voltage and current peaks and valleys at the start of the vehicle, affects the operation of the driving recorder. Moreover, the battery is directly taken through the step-down line, and the wiring harness can be introduced from the engine compartment to facilitate the hiding of the harness.
It is highly recommended that consumers use this method in the later stage of modification, because this method requires modification of the power supply facility. If the original factory does not have such a setting, there may be certain safety hazards in the later installation.
Cigarette lighter takes electricity, stable but takes up resources
Ignition of the cigarette lighter is probably the most power-taking method of the current driving recorder. It is mainly for the low-end driving recorder model. The advantage is that the installation method provided by the original factory can be installed directly, but it will occupy the car. The only stable power take-off port inside, we must know that the voltage stability of the cigarette lighter port is higher than that of usb. Most cigarette lighter ports are directly connected to the battery through the buck line, and the power supply is stable. In addition, power supply through the cigarette lighter will also cause some unsightly appearance due to the exposed power cord.
USB in the car takes power, some models have differences
The USB power supply in the car is also the power-taking mode of some of the driving recorders. The USB charging mode in the car is similar to that of the cigarette lighter. It does not occupy only one interface and has certain versatility. However, for some models, the usb power outlet has a certain current peak and valley when the vehicle starts, which may damage the driving recorder. In addition, the usb interface is not suitable for long-term use without plugging. Some models do not supply power after the vehicle is turned off, and cannot meet the 24-hour working requirements of the driving recorder.
Obd interface takes power, the cost is slightly higher
If a professional third-party maintenance organization installs a driving recorder, it is often recommended to use the obd interface to take power. This method is safer than other methods and is suitable for most current driving recorders. The obd interface has certain versatility, and the working voltage is the most stable except for the original power take-off mode. However, the obd interface needs to use the wire harness dedicated to the obd interface, which is slightly higher than other solutions.
The obd interface can also be used to hide the wiring harness. The obd interface of the general vehicle is located below the instrument panel, and the hidden cost is lower.
Reading lamp power, cumbersome operation, high reliability
Some consumers also use the wiring harness in the reading lamp to take power. This method is cumbersome and can only be carried out in a professional maintenance organization, but the reliability is relatively high, because our reading lamp takes a relatively stable voltage, but there are It may cause loss of some functions of the reading light. This method has also been abandoned by many manufacturers, and incorrect modifications may cause short circuits in electrical appliances.
Take the fuse box and choose more
The fuse box is also a common way to take power. The fuse box is relatively stable, and the interface has certain versatility. No additional modification is required, but for the average consumer, it is impossible to judge which interface is capable of supplying power. . Therefore, consumers are not recommended to do it themselves.
