Should the dash cam memory card memory be dedicated?

1. First of all, it depends on what is the maximum memory supported by your recorder, if it is 32G, then the maximum can be selected32, if it is 64G or 128, then you can choose a larger one.

2. Look at how long you usually drive each time, for example, your recorder 8G can record for 1 hour at the highest resolution, then the recorder now has a loop recording function, that is, after the recording is full, the old ** will be deleted and the new one will be recorded, then you will not drive for more than 1 hour each time, 8G is enough, if you choose 16G within 2 hours

If you choose 32g within 4 hours

3. Theoretically speaking, the larger the memory card we choose, the better, the reason is this, the memory card has a service life, because every time you record full, delete and then record, it is equivalent to erasing and writing the memory card, the memory card erase and write times is limited, then the memory card can not be erased after a certain number of times, then the smaller the memory card, the higher the frequency of erase and write, the shorter the service life, the larger the capacity of the memory card, the less the number of erases, the longer the service life.

4. According to the use of the recorder, a high-speed memory card, basically every 3-6 months, you should need to check it to see if it needs to be replaced, this is not a problem with the recorder, because erasing is a must, now a 32G memory card is not expensive, basically around 80, according to the fastest 3 months (90 days) to replace one, which is equal to less than 1 yuan per day, of course, some people do not drive every day, maybe 6-12 months need to be replaced.

At present, the dash cam on the market only supports the memory card up to 32G, and it can be seen from the above figure that 32G can record for about 8 hours; The maximum recording time of 16G is about 4 hours; The 8G can record for about 2 hours at most. As a merchant and a user at the same time, I personally feel that the memory card is too large and useless, why? Next, I will state the reasons and personal experience:

1.I believe that everyone installs a dash cam, all considering that in case of an accident, this can be taken out as evidence in court, and everyone has to figure it out here - what you really need is only a few minutes before and after the accident, and the accident is only a few minutes or even a second! Plainly.

No matter how big your memory card is, no matter how much content you record, but what you really need is only a small bit, and everything else is useless, it will be overwritten; 2.Many friends may say that if the card is too small, if the driving time is too long, then the back may wash out the front video content, maybe half of it will be washed away when you drive home. This is a lot of thought, when you think which video is useful while driving, you can lock a certain ** according to your needs, so that it will not be washed out; 3.

If you think that the 8G card is small, you can get a 4G or 2G card, and if you need to keep it, you can change the card, and it is really unnecessary to buy such a big card. At first, I used 32G, and I really felt that it was not very useful when I used it, so I changed it to an 8G one. Although there is only a difference of dozens of dollars on the two cards, dozens of dollars are also money, I believe that "the Yangtze River does not choose a trickle, so it can travel thousands of miles" The truth everyone understands!

Dash cam memory card selection method:

1. The recorder, like the mobile phone, has a memory that supports maximum expansion.

2. If the memory is too large, it will be impossible to write data, and it is useless, so choose a memory card and know your own recorder.

3. Understand the longest recording automatic coverage time of your recorder, and choose the appropriate covering and branch collapse time, which is generally 3 minutes on the market.

4. Determine the size of the memory card and the read and write speed of the memory card.

5. The reading and writing speed theoretically affects the storage speed, but in practice, the performance of each type of recorder is different, some may write fast, some slower, and correspond to the memory card.

The memory card of the dash cam is generally used with 32G.

The recording duration supported by different embedded banquet early memory cards is different, 8G can only record for about 2 hours at most, and 16G can record for about 4 hours, 32G can record for about 8 hours, and the dash cam only supports the memory manuscript card up to 32G, so the inner key of the dash cam car is generally used for 32G.

Dash cam

A dash cam is an instrument that records the image and sound of the vehicle while it is on the road. The function of the dash cam is to record the best images and sounds of the whole process of driving, which can provide evidence for traffic accidents.

Precautions for dash cams and memory cards

1. When driving long distances, you can moderately reduce the resolution of the dash cam, and seek a longer storage, if it is a short-distance driving in the urban area, you should maintain high resolution and take a large number of key points.

2. When purchasing a dash cam memory card, the quality should be ensured, and the capacity and reading and writing ability rate should be suitable for the dash cam, otherwise, it may endanger all normal ** recording, and even burn the memory card.

3. The dash cam memory card must depend on the capacity that the dash cam can support, and the larger the capacity within the capacity supported by the dash cam, the better. However, we can't blindly seek large capacity, otherwise it will happen that the dash cam can't identify or the ridge only records but doesn't store.
