How long can a dash cam with a memory card 4G generally record?

It's short, at least 16g makes sense.

The dash cam memory can have a 100,000 erase life. Of course, the memory chips used in inferior SD cards may be defective or reworked, and the life span will be greatly reduced.

When using SD or MMC cards, if you need to copy smaller files from your computer, try to copy them with your mobile phone, and don't use a card reader alone, after all, the contacts will wear out if you unplug and unplug more times.

Dash cam features:

At high speeds, the image captured by the dash cam changes very quickly, which is a severe test for the imaging and processing speed of the machine. We used A4 paper to imitate the form of a car license plate and printed a license plate;

There is a person standing on the side of the road, holding a printed license plate in his hand, and using a car equipped with a dash cam to pass at different speeds to compare the impact of the speed on the shooting effect of the dash cam.

There is no definite answer to this, under normal circumstances, if it is a good product from a large factory, it is no problem to use it for a few years, but it also depends on the quality of the memory card, and the time will be longer.

Generally speaking, 64GB or even larger can be supported at the momentMemory cardIt is recommended to purchase a 64GB memory cardGenerally, it can meet the record of about 6 hours; Dash cam.

It's all looped, and the content before the time exceeds will be overwritten.

Here's a closer look:

1. First of all, check what is the maximum support of your recorder, if it is 64GB, then 64GB can meet about 6 hours of recording, and 32GB can also meet about 3 hours.

2. The length of storage time of the dash cam generally depends on the size of the memory card and the storage file format.

The larger the capacity, the longer the recording time; Dash cams are all recorded in a loop, and the content before the time exceeds will be overwritten.

Dash cam memory cards generally have a capacity of 8G, 16G, 32G, and 64G on the market, which can be selected according to your needs. Dash cams are looping recordings, but in order to be able to keep as many recordings as possible for a period of time, it is recommended to use a 16 or 32GB memory card. The driver can choose the memory card of different dash cams according to his different driving hours, so as to avoid insufficient capacity when in use, which affects the use and cannot guarantee driving safety.

Generally, 8G, 16G and 32G memory cards are optional, and you can also buy a card with large memory.

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. However, if you think it's okay to buy a large memory.

When driving, you can record the time, speed, and location in the video, which is equivalent to a "black box". It can also be used at home as a DV to capture the joy of life, or as a home monitor. Parking monitoring can also be done at ordinary times.

Dash cams are mainly divided into portable dash cams and after-loader integrated dash cams.

It's really a big head.,I just bought a new memory card two days ago and installed it on the dash cam.,Why is it not enough today.,So,How big is the dash cam memory card generally used?

Hello, dash cam memory cards generally use 16 32 or 64G more.

Use 16g to 32g will do. No matter how big it is, it doesn't make sense.

Generally 64 is enough for 64 memory.

Then the memory card I bought didn't work for less than 2 months, what does it mean?
