How to Identify and Test Fake 

Memory Cards ? 

Micro SD Card and fake SD Card

An SD Card is a small electronic storage medium used by a plethora of storage devices including smartphones, games devices, camcorders, and cameras. Most of the smartphones and security cameras are using the micro SD card. 

The TP-Link camera supports a micro SD card with up to 128GB capacity. If the remaining space of an SD card is less than 500MB or 5% of the total capacity before the first insertion of the camera, it would be impossible to record. 

There are different speed specifications for micro SD cards and it is recommended to use a card with Class 10 or UHS 1 speed rating, which requires a minimum writing speed of 10MB/s. The most common fake SD card is the fake capacity expanded card, which uses illegal means and tools to make the cards with a small capacity appear larger. 

For example, a 32GB card is displayed as 128GB on your computer or other devices. This kind of card is usually has a lower price than the official quality goods. Since the capacity is Manual deceived by the illegal means and tools so that the space beyond the original capacity cannot be used normally. As long as the stored file exceeds the actual capacity, the file will be unavailable. Our camera recognizes the SD card and will format it in Fat32 format and creates index files to save your video data. This process reads and writes the entire space of the SD card and checks whether it is valid. 

If your SD card is an expanded card, it will not be formatted successfully and will not work properly on our camera. We do not support the card due to the particularity of the monitoring camera, we need to ensure that the SD card can work stably for a long time. And since camera data is relatively important, data loss or failure to write data can have a significant impact.

Fake Memory Card Issues

So what happens when you have a fake / counterfeit memory card? Well, as you can see from the earlier section, the issues can range from getting very slow speeds all the way to data loss and unusable memory cards. Out of all the potential issues, data loss is the biggest risk, especially when a large capacity memory card is used. The problem with fake memory cards with reduced capacity, is that many photographers might not understand that once they go over a certain capacity, all data from that point on will be corrupt. So everything might appear to be working great at first, only to have troubles show up later. This is especially problematic when photographers plan expensive trips where memory cards fail after a few days of use. 

So the biggest risk one might run into, is loss of data – that’s where you do not want to end up! And having a dual memory card slot camera is not going to help in any way with fake cards, because both will fail at some point. This is why it is especially important to identify fake memory cards and get rid of them. 

Fake Brand Checking

Some memory cards have big brand labels attached to them and sold at a premium price, when in reality they are made from cheap parts by some unknown manufacturer in Asia. In some cases, it could be a small manufacturer that sells “rejects” from bigger brands, and in other cases it could be a real OEM product from a legitimate manufacturer with misrepresented specifications. Such products are often more difficult to identify and might require a call to the manufacturer to verify the serial number.
