XXI century - the era of digital technology and universal video surveillance. Most often, the shooting takes place from under the windshield of a passing car. Sometimes it happens that the DVR does not see the memory card. How to be in such a situation will be discussed in the article.
About devices
Hour traffic jams are a hallmark of large cities. This is due to the fact that equipment comes off the assembly line in increasing quantities. Highways do not have time to grow at the same pace. Therefore, the likelihood of an accident increases.
A driver who is interested in ensuring that the culprit does not go unpunished (and in general, so as not to be extreme himself) installs a gadget in the car that continuously records everything that happens.
Why do I need a memory card
The videos are saved in AVI or MKV formats on a microSD card. Recording is cyclic, old videosare removed, their place is filled by new ones.
If there is a shock sensor, then the gadget automatically starts recording. The result is placed on a special stack protected from erasure. The image is overlaid with a graphic date and time stamp, making it easy to restore the details of what is happening.
The memory card stores information on time periods before and after the event. It all depends on the options. Therefore, if the DVR does not see the memory card, the driver may lose valuable material that can reproduce the details of the collision. This is not allowed!
Why the DVR does not see the memory card
The video recorder is a reliable thing, but capricious. If a bad storage source is used or if the flash drive is not installed successfully, the product will not recognize it. In addition, if the hardware is damaged, there is no guarantee that the information on the MicroSD will be correctly recognized. Why can't the DVR see the memory card?
It is important when buying a gadget to immediately check the functionality of all components in order to avoid unpleasant surprises later.
The most common are:
- factory marriage not detected in time;
- malware on flash drive (viruses or worms);
- incorrect device formatting;
- differences in writing speed and file storage class.
Often, gadgets do not see the map due to a mismatch between the file systems in which the formatting was originally performed. For example, the system is FAT32 on the device, and exFAT on the flash drive. Therefore, it can be recognizedonly the first option with full compliance. The solution to the problem is extremely simple: re-formatting in the desired file environment.
The reason for incorrect operation may also be poor-quality Chinese samples of memory cards, which are generally read in few places. Such microSDs can only work for a couple of months at all, and sometimes they are not recognized even on first use.
Verdict
Inattentive buyers and those who want to sell cheap may have situations when the DVR does not see the memory card. What can be done to avoid such excesses?
You should be more sensitive to the choice of model. The device is always accompanied by an instruction that describes all types and classes of memory cards with which the product can interact.
Based on the information, you can choose the right media. Attention should also be paid to the adopted mechanisms. All flash drives are divided into classes, which accept different values for the speed of downloading and receiving files. It is better to purchase at least 10 classes. Most gadgets work with just that.
Sometimes there are failures, and the DVR does not see the memory card. If there are suspicions of viruses on removable media, it is better to connect the product to a computer and perform a complete system diagnosis. The anti-virus program will successfully detect all malicious files and eliminate them permanently.
