This article introduces the bandwidth required for Live View, FTP Uploading, Email Alerts and Push Notifications for Reolink IP cameras.

Applies to: All Reolink IP cameras (Reolink battery-powered cameras, E1, E1 pro, E1 zoom, B400, D400, B800, D800, and cameras connected to Reolink NVRs excluded).

1. Bandwidth for Live View

Note: The bandwidth of Reolink IP cameras depends on the Stream Mode you choose.

If you choose Clear mode, then the bandwidth is the same as the Bitrate under clear mode.
If you choose Fluent Type, then the bandwidth is the same as the Bitrate under fluent mode.

In Clear mode: the maximum Bitrate is 8192 kbps

In Fluent mode: the maximum Bitrate is 512 kbps

​You may change the bitrate and set the stream mode to view the cameras.

2. Bandwidth for FTP Uploading

In Clear mode: the maximum Bitrate is 8192 kbps

In Fluent mode: the maximum Bitrate is 512 kbps

You may set up the upload video resolution according to your needs.

3. Bandwidth for Email Alerts

The bandwidth for email notifications is not very high. You can choose to attach text, a picture, text & pictures, or text & video to the email alerts. If you set the email notification to attach text & video, the required bandwidth is about 1.6kbps (for cameras with hardware IPC_515/513).

You can set up the email attachment here.

Note: The videos attached in the email are 8s long. The length cannot be changed. The camera will send 4KB data every 20s. For cameras (hardware IPC_515/513), the bandwidth for email notification (with video attached) is 4KB/20s=1.6kbps.

4. Bandwidth for Push Notifications

Bandwidth for push notifications can be ignored, as the push file is very small (less than 1KB) so it takes up a very small amount of bandwidth.

If you have the camera upload the clear video (maximum bitrate) to the FTP server, view the clear video (maximum bitrate) on Reolink App at the same time, and have enabled the email notification with a video attached, the total bandwidth needed would be: 8192+8192+1.6=16385.6kbps, approximately 16Mbps.
