How long can the SD card record

If you have bought (or are planning to buy) Reolink cameras with a SD card, such as 410S, 411S, 410WS, or 411WS, you can refer to this post to figure out how long the SD card can record videos.

Note: The SD card is only for motion detection recording.
Bitrate will affect the recording file size. The higher the bitrate is, the better image and audio quality will be, the bigger the file size will be and vice versa. So the time is inversely proportional to the bitrate in the limited storage space, and here is the formula:

And our SD card is 16GB, so here is the result for reference:
