How to choose the memory card of the driving recorder? Durable protection capacity and speed are important

Time: May 20, 2021Views: 175

Driving on a car road will inevitably lead to some accidents, such as collisions with other vehicles or someone coming to touch the porcelain to cheat money. If there is a dash cam in the car, it can be a good way to sort out the person responsible at the scene of the car accident. It can provide strong video evidence when there is a porcelain collision problem, so it is necessary to install a driving recorder in the car.


However, many people often pay too much attention to the driving recorder itself when buying a driving recorder, such as paying attention to its image quality, how to control or battery life related issues, but they often ignore the purchase of microSD memory cards, if they do not choose a suitable memory card , It is possible that the memory card will be scrapped directly after using it for a period of time, which will add unnecessary trouble to yourself. So how do we choose a memory card suitable for driving recorders?


1. High durability and high protection

The use of the driving recorder mainly plays the role of monitoring, so long-term non-stop recording is the normal state of its work, which puts a lot of pressure on the continuous reading and writing and rewriting of the memory card, and a lot of storage Stuck in long-term recording may cause problems, resulting in video recording failure and not allowing the driving recorder to perform its due function.

It is inevitable that the device will heat up during long-lasting recording. In addition, when summer is approaching, the big sun will directly hit the dash cam in fine weather. At this time, the heat resistance performance of the memory card is particularly tested. It is easy to use a heat-resistant memory card. problem appear.

At the same time, everyone can pay attention to the waterproof standard of the memory card. As the waterproofing of the driving recorder, the memory card is mainly concerned with the damp problem of the memory card in rain and snow. You don't need to pay too much attention to the waterproof characteristics like diving and extreme sports users. Generally speaking, the IPX7 standard will do. In addition, because the microSD memory card itself is small in size, it is easy to fall if you are not careful, so the anti-drop characteristics also need to be paid attention to. Generally, the anti-drop characteristics of more than 2 meters are sufficient.

2. Large-capacity read and write fast

The better the video quality of the video captured by the driving recorder, the clearer the record, the clearer the license plate number of the vehicle in front can be clearly recorded. At present, the basic highest specification of the driving recorder is 4K resolution. If there is a 4K recording requirement, then you must first Check whether the memory card and the packaging of the memory card are marked with the V30 mark. Because 4K video must meet the writing requirement of 30MB/s, the memory card with the V30 mark can record 4K video.

But remember, the better the picture quality of the dash cam, the higher the storage capacity requirements. If you use the dash cam to shoot 4K video, you have to consider choosing 256GB to start, if you shoot 1080p The storage pressure will be slightly lower for the picture quality, but the 1080P video capacity is also very scary for a long time. If the capacity is small, the memory card may be full and the overwrite recording will be performed. At this time, look at the earlier screen content. It can’t be achieved. Subsequent recordings will overwrite the content recorded at the beginning. A memory card with a smaller capacity can be deduced by analogy. Therefore, if the memory card of this type of driving recorder is still shot at 1080P, it is better to start with 128GB. Well, if you usually only focus on short-distance driving, you can appropriately consider the small-capacity memory card, but no one can say anything about it, so try not to consider the low-capacity version.

Recording videos need to pay attention to the writing speed of the memory card, while reviewing the content pays more attention to the reading speed. Generally speaking, the reading speed requirement will be higher when recording high-quality videos. In view of the current video specifications of the driving recorder Only 4K, the UHS-I standard read speed can theoretically reach 104MB/s, so the UHS-I standard memory card read performance can be adapted to the copy and playback of 4K video, and the UHS-I standard memory card is also Usually marked with the U1 logo.

3. Reliable flash memory particles

The core component of the memory card to store data is still flash memory particles. High-quality flash memory particles can ensure the reliability of the memory card. If the quality of the flash memory particles is not good, the memory card is particularly easy to roll over. This problem is mainly reflected in some less well-known memory cards. , The poor workmanship and materials are the main reason for their low prices. Relatively speaking, the quality of the products of well-known storage manufacturers is relatively reliable. Therefore, it is better to choose the products of well-known storage manufacturers for the memory card of the dash cam. Their flash memory particles It is trustworthy. Don't try to buy memory cards of non-mainstream brands at low prices. For example, KIOXIA's EXCERIA HIGH ENDURANCE highly durable series of memory cards use Japanese original core technology and high-quality flash memory particles, which are as durable as previous Toshiba memory cards.
