The following information is normally found in the first couple of pages of our IP camera manuals:

It is VERY important when using micro SD cards for recording, that the cards are rated for heavier usage.
All flash memory has a finite number of write cycles. Meaning that, unlike a spinning magnetic hard drive.
Most off-the-shelf micro SD cards that can be bought online or from a local retailer will be consumer-grade flash memory with a rough max number of writes to a cell of about 3,000 to 5,000 writes, before a permanent failure will occur in each cell.
Below are some estimations on write cycles.
Triple Level Cell - Consumer-grade flash:
3,000 to 5,000 write cycles maximum
Multi-Level Cell - MLC - Is middle range flash memory, used in a number of commercial applications:
8,000 to 10,000 write cycles maximum
SLC - Single-Level Cell - is high-level flash memory. Normally used in SSDs but is available for micro SD cards.
90,000 to 100,000 write cycles maximum.
