Can a dash cam record sound inside the car?

A dash cam can record sound inside the car. After installation, it can record video images and audio of the entire driving process, which can serve as evidence in traffic accidents. Precautions for using a dash cam: Regularly process data to prevent inconvenience caused by data loss when needed. Additionally, always purchase certified products with 3C quality assurance. For the installation position, try to mount it near the interior rearview mirror for optimal visibility. Also, ensure the lens is within the wiper cleaning range to maintain clear recording during rain. The installation position should not interfere with the car's airbag deployment range. Furthermore, since high-definition processing in dash cams generates significant heat, prolonged exposure to sunlight and extended use of car power supply can lead to crashes or black screens. Therefore, it is recommended to use battery recording rather than relying on external power for long periods. Basic components of a dash cam: Main unit: Includes a microprocessor, data storage, real-time clock, display, lens module, operation keys, printer, data communication interface, and other devices. If the main unit does not include a display or printer, it should have corresponding data display and print output interfaces; speed sensor; data analysis software.

What is the difference between reverse gear and first gear?

The differences between reverse gear and first gear are as follows: 1. Reverse gear: The reverse gear is a driving gear available in all vehicles, usually marked with a capital letter R. After engaging the reverse gear, the vehicle's direction of movement will be opposite to that of the forward gear, enabling the car to move backward. When the driver moves the gear lever to the reverse position, the direction of the power input wheel from the engine remains unchanged, but the internal reverse output gear of the transmission engages with the output shaft, driving the output shaft to rotate in the opposite direction, ultimately causing the wheels to rotate in reverse for backing up. 2. First gear: First gear is a low-speed gear used for starting, climbing hills, or decelerating.

What is the difference between 24V and 36V?

The differences between 24V and 36V are as follows: 1. 24V DC power supply: A DC power supply has two electrodes, positive and negative, with the positive electrode having a higher potential and the negative electrode having a lower potential. When the two electrodes are connected to a circuit, the DC power supply can maintain a constant potential difference between the two electrodes, thereby forming a constant current from the positive to the negative electrode in the external circuit. 2. 36V voltage: Safety voltage refers to a voltage that does not cause direct death or disability. Under general environmental conditions, the allowed continuous contact 'safety extra-low voltage' is 36V. Industry regulations stipulate that the safety voltage should not exceed 36V, the continuous contact safety voltage is 24V, and the safety current is 10mA. The degree of harm caused by electric shock to the human body mainly depends on the magnitude of the current passing through the body and the duration of the current flow.

What is the difference between Nissan's blue logo and non-blue logo?

The following are the differences between the blue logo and non-blue logo: 1. Different LOGO colors: The dual product lines are represented by the red LOGO and blue LOGO. The red logo Haval embodies luxury and classic, aiming to cover the mainstream home market. The blue logo Haval embodies coolness and fashion, mainly targeting young groups. 2. Differences in the front face: The front face of the red logo version is shield-shaped, while the blue logo version is a flat hexagon. 3. Slight differences in body size: In terms of body size, the blue logo Haval H1 is 77mm longer than the red logo version, reaching 2460mm. This means that the rear seat space of the blue logo version is slightly larger than that of the red logo version. The rear seat riding quality is relatively better.

What is the difference between automatic transmission and manual transmission in Subject 3?

Subject 3 manual transmission and automatic transmission are different as follows: 1. Automatic transmission: Automatic transmission eliminates the gear shifting process. Among the 16 test items in Subject 3, gear shifting is one of the more difficult actions. Many people fail the manual transmission test due to incorrect gear shifting, but automatic transmission eliminates this possibility as it does not include this item. 2. Manual transmission: Manual transmission requires the driver to coordinate with the clutch for gear shifting, while automatic transmission operates based on preset gear ratios by the transmission system without manual intervention. The difference is that automatic transmission makes gear shifting simpler with fewer shifts, while manual transmission requires step-by-step gear shifting.

What is the difference between Shell gasoline and Sinopec gasoline?

The differences between Shell gasoline and Sinopec gasoline: 1. Different additives: Shell gasoline contains a new formula additive developed by Shell, which is an upgraded version - 2000 type for diesel and 6122 type for gasoline; Sinopec gasoline uses ordinary additives and imports low-grade, high-sulfur crude oil from the Middle East. 2. Different durability: Shell gasoline is certified by the Society of Automotive Engineers (SAE) and tested by the Chinese Research Academy of Environmental Sciences, proving that its unique formula is particularly effective in cleaning engines, optimizing engine performance for fuel efficiency and protective cleaning effects, making it more durable than Sinopec gasoline.
