What type of memory card is used in a dash cam?

Should the G-sensor of the dash cam be turned on?

The G-sensor of the dash cam can be turned on. However, it is best to set it to a low option and regularly format the memory card to prevent the memory card from storing too many videos that cannot be overwritten, which would reduce the available memory for loop recording. Here is some relevant information: 1. G-sensor: The G-sensor, also known as impact storage, works by detecting when the value read by the dash cam's CPU from the gravity sensor exceeds the set threshold, indicating a collision. It then protects the current video segment from deletion, thus enabling automatic storage upon collision. 2. Composition: The G-sensor system is a sophisticated protection device, typically consisting of three parts: the sensor, processor, and controller. For dash cams, the G-sensor is the sensor, while the processor and controller are the main chips of the dash cam. Once the sensor detects and the processor determines that the current gravitational acceleration exceeds the specified value, the controller will issue instructions to specially protect the current video file or sound an alarm. This series of actions is completed within 200 milliseconds. The device will resume normal operation only after the sensing device detects that the acceleration value has returned to the normal range.

What types of vehicles can be driven with an A2 driver's license?

A2 driver's license permits the operation of tractor-trailers. Holders of a valid A2 license issued by China's public security traffic management authorities can drive heavy and medium-duty full trailers and semi-trailers, as well as vehicles permitted under B1, B2, C1, C2, C3, C4, C6, and M licenses. Details are as follows: B1 license: Permits driving medium-sized passenger vehicles not exceeding 6 meters in length, with a seating capacity of 10 to 19 passengers. B2 license: Permits driving heavy and medium-duty trucks or large, medium, and heavy-duty specialized operation vehicles, commonly known as cargo trucks on the road. C1 license: Permits driving small and mini passenger vehicles, as well as light and mini cargo vehicles, and light, small, and mini specialized operation vehicles. C2 license: Permits driving small and mini automatic transmission passenger vehicles, as well as light and mini automatic transmission cargo vehicles. C3 license: Permits driving low-speed cargo vehicles. C5 license: Permits driving small automatic transmission passenger vehicles specially designed for disabled individuals. C6 license: Permits driving light trailer vehicles. M license: Permits driving wheeled self-propelled machinery. Since an A2 license can only be obtained through an upgrade, the prerequisite for obtaining an A2 license is holding a B1 or B2 license. A B2 license can be applied for when initially obtaining a driver's license, but the applicant must be at least 20 years old. A B1 license requires an upgrade from a C1 license. After meeting the corresponding conditions for upgrading to an A2 license, applicants can submit their documents to the traffic management office. Upon passing the physical examination and other reviews, they can enroll in a driving school for training.

What is the Difference Between CVT and Automatic Transmission?

There are several differences: 1. Literal meaning: A continuously variable transmission (CVT) has no fixed gear ratios, while an automatic transmission controls each gear with a set of clutch plates to achieve shifting. 2. Structural differences: The CVT has a simpler structure than traditional transmissions, with a smaller size. It lacks the multiple gear pairs of manual transmissions or the complex planetary gear sets of automatic transmissions. Instead, it mainly relies on two variable-diameter pulleys to achieve seamless ratio changes. 3. Gear shifting differences: An automatic transmission simply changes the shifting motion of a manual transmission into linear movement, achieving automatic operation in terms of motion direction, but it still shifts gears step by step from low to high speeds. In contrast, a CVT no longer shows visible gear increment or decrement markings, only directional indicators like forward and reverse. CVTs provide smoother performance than automatic transmissions during high-speed overtaking and cornering.

Can Shampoo Really Be Used to Wash Cars?

Shampoo can temporarily be used as a substitute for car wash soap. The main ingredients of car wash soap are generally similar to those of shampoo. Here is some information about car wash soap: 1. Function: Car wash soap contains natural wax components, which can give the car body a clean and shiny appearance and provide a certain elasticity to the paint surface, preventing minor scratches from small flying sand. Some car waxes also have strong UV resistance, protecting the paint surface from UV damage. 2. Precautions: Avoid washing the car when the engine is not completely cooled down, as this can lead to premature aging of the engine. Also, avoid washing the car under direct sunlight, as this can leave dried water spot marks on the car body.

How to Choose Between Sedans and SUVs?

Selecting between sedans and SUVs depends on different needs. This guide introduces car-buying choices from five aspects: travel scenario requirements, comfort needs, appearance preferences, space requirements, and family needs. Below is the demand analysis for sedans and SUVs: 1. How high are your space requirements: In fact, the most obvious difference between SUVs and sedans is space. The advantage of SUVs lies in their larger interior space, though correspondingly, their body size is also bigger than sedans. When choosing a car, you can consider space factors. The trunk space of an SUV is much larger than that of a sedan, and the rear seats can be folded down. If you often need to carry large items or require extensive space overall, an SUV might be the better choice. If your space needs aren't substantial and the car is mainly for commuting and daily travel, a sedan is entirely sufficient. 2. What kind of seating position do you prefer: Sedan seats are relatively low, making your legs appear higher and your hips deeper when seated, creating a somewhat reclined posture. This position can be more comfortable during long drives. However, this seating position also has its drawbacks, primarily regarding visibility. Sedans generally don't offer as good a view as SUVs. When driving in narrow spaces with limited visibility, you might need to lean forward over the steering wheel for a clearer view, which can be tiring over time.
