Applies to: Reolink Go.
For Reolink Go, data usage depends on the bitrate you have set for the camera. The default bitrate is 1.5 Mbps (for the mainstream, up to 2 Mbps)/160 kbps (for the substream, up to 512 kbps).
You may refer to the steps in Set up the Quality Settings via Reolink App to find the bitrate setting in the Quality page.
With the default settings, if you preview in mainstream type about 1 minute per day (about 12-15 minutes in substream type per day), it needs 1 GB monthly.
Note: It is just for reference, the actual data usage is based on the actual working situation.
