There were actually two micro SD cards; one of them is 64G (grade 10), which is what the DVR needs. After a minute of filming, the camera suddenly stops recording and claims delayed recording and a recording buffer overflow error. The problem persists even after the card has been formatted. Kingston (Canvas Select line) was the most suitable option for me in terms of price and performance among the options available on our market. In addition, there is a lifetime warranty from the manufacturer, though not on us just yet. Nonetheless, this factored into the decision as well. Therefore, when everything operates smoothly as clockwork.
