Does the Dash Cam Have Interior Sound Recording?

Dash cams are typically equipped with an external camera, primarily designed to record the driving conditions outside the vehicle. However, they can also capture sounds inside the car, though they do not record interior images. Most dash cams offer two wiring methods: connecting to the cigarette lighter or to the fuse box. 1. Cigarette Lighter Connection: The advantage is simple wiring, but it may affect aesthetics and occupies a cigarette lighter port. Normally, the cigarette lighter is connected to the ACC (Accessory) power, meaning it only has power when the ignition is on. Therefore, dash cams connected to the cigarette lighter cannot support 24-hour parking surveillance. 2. Fuse Box Connection: This method allows direct connection to the car battery, enabling 24-hour parking monitoring. However, the downside is that it's more complicated and usually requires professional installation. On the plus side, this method hides all wiring, resulting in a cleaner and more aesthetically pleasing setup.

Why is a new car leaking water?

Car water leakage is a common phenomenon, which mostly occurs at the opening and closing points of doors and the trunk. The main cause of this issue is usually related to the waterproofing strips, i.e., poor-quality, aged, or cracked rubber waterproofing strips, allowing rainwater to seep in. 1. Common car water leakage scenarios: The waterproofing strips embedded around the doors are prone to misalignment. If rainwater enters the car, check the waterproofing strips. Leakage around the doors is mostly due to the surrounding waterproofing strips; inspect for any cracks or peeling. If part of the waterproofing strip is lifted or twisted, rainwater often seeps in from there. Severe deformation requires replacement. 2. Precautions: Although water leakage inside the car is not a major issue, it should not be ignored. Rainwater that seeps in from the outside or is brought in by occupants can be absorbed by floor mats, seats, and other interior decorations, lingering inside the car for a long time. As temperatures rise, this creates a "breeding ground" for bacteria, posing health risks to the car's occupants.

How Long Can a Repair Shop's Paint Touch-Up Last?

After a car paint touch-up, the color can remain unchanged for up to 5 years, but this largely depends on the driver's habits. 1. Touch-up Time: For traditional paint touch-up methods, whether at a 4S shop or a specialized repair shop, it typically takes 1-2 days to complete. Only small-area touch-ups can be finished within a few hours. The vehicle can be driven away on the same day after the touch-up, but it's important to avoid contact with corrosive cleaners like adhesive removers or asphalt removers on the touched-up areas, as they can severely damage the new paint, even causing it to melt completely. 2. Precautions: Avoid using high-pressure water to wash the car body directly. The hardness of the touched-up paint is lower compared to the original factory paint, and excessive water pressure can damage the car's paint surface. Also, refrain from indiscriminately using cleaners. While driving, the vehicle is inevitably exposed to substances like asphalt, oil stains, and insects, which require careful handling.

What is the specification of a chainring?

Chainring specification refers to the size of the chainring. 1. Chainring: The part of a bicycle that connects the bottom bracket and the crank. By pedaling, the crank is driven, which in turn drives the rotation of the chainring, ultimately driving the rear wheel through the chain and the freewheel, providing power and completing the entire drivetrain of the bicycle. 2. Crank material: Designed for high-intensity use. In terms of materials, cranks of similar strength made from high-quality aluminum alloy are lighter, offering better cost performance. Carbon fiber cranks have excellent rigidity. Although they are slightly lighter than aluminum alloy ones, they are more expensive and more prone to damage in case of a fall.

How to Release the Clutch After Downshifting?

How to release the clutch after downshifting: 1. Lightly tap the brake with your right foot; 2. Control the vehicle speed within the same range as the corresponding gear speed, then release the clutch. Manual transmission vehicles use a manual shift mechanical gearbox to adjust speed. By manually moving the gear lever, the gear meshing position inside the transmission is changed to achieve different gear ratios for speed variation. As a component for distributing power, the transmission consists of an input shaft, output shaft, and gears. The manual transmission gears are divided into: first gear for starting; second gear for acceleration; third gear as a transition gear; fourth gear for normal driving; fifth gear for high-speed driving; and R gear for reverse.

For the driver's convenience, to prevent traffic safety accidents, and to ensure personal safety, the rearview mirror can be adjusted in direction. Functions of rearview mirrors at different positions: 1. Interior rearview mirror: A mirror that allows the driver to confirm the rear situation while looking forward during driving; 2. Exterior rearview mirror: Installed on the car door, it enables the driver to see vehicles behind; 3. Under mirror: Allows the driver to see areas outside the front and rear wheels under the car body through the mirror directly in front of the driver's seat.
