Store and forward is a media loss prevention mechanism that protects pictures and videos during an Internet or WiFi outage. In the case where the camera cannot connect to the Cloud, all files are temporarily buffered and stored on the built-in Micro SD card.
When connectivity is restored, all buffered files are automatically forwarded from the Micro SD to the Cloud. Store and forward requires that a Class 10 Micro SD with at least 4GB of free space be installed in the camera. Cloud mode will not operate unless the Micro SD is installed. In the event of a power failure the buffered media is retained on the Micro SD indefinitely.
