A 32GB dash cam can record for four to five days. Nowadays, dash cams have become essential equipment for many car owners. Due to the frequent occurrence of "crash for cash" scams in many areas, many drivers have no choice but to install dash cams in their vehicles. In critical moments, the footage from a dash cam can serve as evidence for traffic police, helping to protect the legal rights of car owners. Generally, a 32GB dash cam meets daily needs. Dash cams record in a loop mode, where videos are stored in segments of fixed durations, such as 1 minute, 3 minutes, 5 minutes, or 10 minutes. When the memory card is full, newly recorded videos will overwrite the oldest segments, which are the ones farthest from the current time. This mechanism ensures continuous recording without interruption due to insufficient storage space.

It depends on your dashcam settings. I also use a 32G card, which can record about four and a half hours at 1080P resolution. If you switch to 2K HD, the recording time is halved to just two hours. However, most dashcams now have loop recording, so it's definitely enough for daily commutes. The key is to buy a high-speed card - I once bought a cheap no-name card and ended up with failed emergency video saves. For long trips, I recommend keeping a 64G card handy. Last year during a road trip I switched cards and could record the Sichuan-Tibet route scenery without worrying about overwriting. By the way, parking surveillance mode consumes a lot of memory, so it's best to use a 128G card if you enable this feature.

Can I Buy a New Energy Vehicle with a Regular License Plate Obtained Through Lottery?

The license plate obtained through lottery can be used on new energy vehicles. The application conditions for new energy vehicles are the same as those for regular indicators. Based on the principle of "allocating indicators free of charge through lottery," a separate "lottery pool" will be established. If the number of applicants is less than the quota for new energy passenger vehicle indicators in the current period, the indicators will be directly allocated. If the number of applicants exceeds the quota for new energy passenger vehicle indicators in the current period, the indicators will be allocated through lottery. Notes for new energy vehicle license plate registration are as follows: Once a new energy license plate is obtained, you can no longer participate in the lottery for fuel vehicle license plates. Only models listed in the latest batch of the Ministry of Industry and Information Technology's "Recommended Catalog of New Energy Vehicles" can be registered. The new energy license plate will be scrapped along with the vehicle. New energy vehicles cannot be transferred or sold within three years. License plates for hybrid and pure electric vehicles are not interchangeable. License plates starting with the letter "D" represent pure electric vehicles, while those starting with "F" represent non-pure electric vehicles (generally referring to hybrids and plug-in hybrids). Lost license plates cannot be reissued. New energy vehicles include pure electric vehicles, extended-range electric vehicles, hybrid vehicles, fuel cell electric vehicles, hydrogen engine vehicles, etc. Details are as follows: Pure Electric Vehicles (Battery Electric Vehicles, BEV) use a single battery as the energy storage power source. They rely on the battery to provide power to the motor, which drives the vehicle. The rechargeable batteries used in pure electric vehicles mainly include lead-acid batteries, nickel-cadmium batteries, nickel-metal hydride batteries, and lithium-ion batteries, which supply power to the vehicle. Additionally, the battery stores electrical energy to drive the motor and ensure normal vehicle operation. Hybrid Electric Vehicles (HEV) have a main drive system composed of at least two individual drive systems that can operate simultaneously. The driving power of a hybrid vehicle mainly depends on its operating state: it can be provided by a single drive system or jointly by multiple drive systems. Fuel Cell Electric Vehicles (FCEV) use hydrogen, methanol, natural gas, gasoline, etc., as reactants that combine with oxygen from the air in the presence of a catalyst to generate electricity, which powers the vehicle. Essentially, fuel cell vehicles are a type of electric vehicle, sharing many similarities in performance and design. They are classified separately because fuel cell vehicles convert chemical energy from hydrogen, methanol, natural gas, or gasoline into electricity, whereas pure electric vehicles rely on charging to replenish electrical energy. Hydrogen Powered Vehicles (HPV) primarily use hydrogen fuel cells as their energy source. They are the most environmentally friendly among new energy vehicles, achieving zero pollution and zero emissions. However, the production cost of hydrogen vehicles is high, exceeding that of traditional fuel vehicles by 20%, and the battery cost is also significant. Due to storage and transportation limitations, they are difficult to apply in practical production. Extended-Range Electric Vehicles (EREV) are similar to electric vehicles, using batteries to provide kinetic energy to the motor, which drives the vehicle. However, EREVs are equipped with a gasoline or diesel engine in the vehicle. When the battery level is too low, the driver can use this engine to recharge the battery.

Can a 4S shop repair tires?

4S shops can repair tires. If the tire is still under warranty and the repair is needed due to a quality issue detected, the repair can be done for free. However, if the repair is needed due to personal reasons, the 4S shop will not provide free tire repair. When repairing a tire, the appropriate method should be chosen based on the specific condition of the puncture: Plugging (for small, obvious punctures or emergency use): Plugging is the simplest and most straightforward method of tire repair. A plug is inserted into the puncture hole using a plug insertion tool. This method is relatively easy and does not require removing the tire from the rim. It is also cost-effective, but it is only a temporary solution and not very durable. It is advisable to perform an internal patch repair later, as long-term use may pose safety risks. Cold Patching (for medium-sized punctures): Cold patching requires removing the tire from the rim, locating the puncture, cleaning the area around it, and then applying a specialized patch from the inside of the tire to seal the leak. This method is similar to patching a bicycle tire but requires specialized equipment and patches. While this method can repair larger punctures, it is not very durable, and the patch may fail again after prolonged exposure to water or high-speed driving. Hot Patching (for medium-sized punctures): Hot patching is similar to cold patching, involving the application of a specialized patch over the puncture. However, it includes an additional step of using a heating machine to melt the patch and bond it to the puncture. The advantage of hot patching is that the repaired area is highly durable and unlikely to leak again. Hot patching requires strict control of temperature and heating time, especially for passenger car tires, which are thinner than truck tires. Improper heating or excessive temperature can damage the tire. Mushroom Plug (for large, irregular, or hard-to-repair punctures): This method uses a mushroom-shaped rubber plug. The plug is inserted from inside the tire, with the stem pushed through the puncture hole. The excess part outside the tire is trimmed, and the inner part is secured with special adhesive. The stem acts as an external patch, while the cap serves as an internal patch. Mushroom plug repairs take longer and are more expensive than other methods, but they offer better and longer-lasting results, making them the best tire repair option.

How to Check the Tire Pressure Monitoring in Sagitar?

The Sagitar's tire pressure monitoring system does not have a separate air pressure display. When the air pressure exceeds the standard value, a yellow light will appear on the dashboard. The illumination of the tire pressure monitoring indicator indicates abnormal tire pressure. Tire pressure monitoring involves real-time automatic monitoring of tire pressure during vehicle operation and alerts for tire leaks or low pressure to ensure driving safety. There are three common types of tire pressure monitoring methods: Direct Tire Pressure Monitoring: The direct tire pressure monitoring device uses pressure sensors installed in each tire to directly measure the tire pressure. It transmits the pressure information from inside the tire to a central receiver module via a wireless transmitter, then displays the tire pressure data for each tire. The system automatically alerts when the tire pressure is too low or there is a leak. Indirect Tire Pressure Monitoring: When the pressure in a tire decreases, the vehicle's weight causes the rolling radius of that wheel to become smaller, making it rotate faster than the other wheels. By comparing the differences in rotational speed between the tires, the system monitors the tire pressure. The indirect tire pressure warning system essentially relies on calculating the rolling radius of the tires to monitor pressure. Introduction to the Tire Pressure Monitoring System (TPMS): It combines the advantages of the two systems mentioned above. Direct sensors are installed in two diagonally opposite tires, and a four-wheel indirect system is also equipped. Compared to using only a direct system, this hybrid system can reduce costs and overcome the limitation of the indirect system, which cannot detect when multiple tires simultaneously have low pressure. However, it still cannot provide real-time data of the actual pressure in all four tires like a direct system.
