Monitor what happens when the memory card is broken.

Listening to memory cards generally means that listening will stop writing data, that is, data will not be recorded from the time of damage. But you can also view real-time monitoring, but you can't play back the last one. If you insert the memory card into the computer, you can't view the previous data. The damaged memory card will be prompted to format before you can view or use it, but the damaged monitoring memory card often can't format, which makes it impossible to view it. In fact, the memory card itself is consumables, and the life of the monitored memory card itself is short, so be sure to guard against the risk of being burned out. If you find that you can't view the previous records, you must replace the memory card in time.
