Applies to: Reolink cameras supporting Micro SD cards
Note: The SD card is only for motion detection recording.
Bitrate will affect the size of the recording files. The higher the bitrate is, the better the image and the audio quality, and the bigger the file size, vice versa. Here is the formula that demonstrates the relation between the SD card Capacity, the Bitrate, and the Recording time.
The formula shows that Recording time is inversely proportional to Bitrate under the same SD card capacity.
Here are some results of Recording time under different Birtrate and SD card Capacity.
|Max. BitRate/kbps||Recording Time/h|
