Battery powered cameras require a connection to a Sync Module and Wi-Fi. Blink Outdoor and Indoor (3rd Gen) cameras will attempt to record the first motion event after a power loss and upload that clip to the cloud once the system is back online. The offline or power-out recording feature is not reliable, however. Power and internet outages are a cause of system problems, for consistent clip recording, make sure both are always available.
