### 4.1.4 Synchronizing Device Data

Synchronize data in the server to all devices in the designated area. (Generally, this operation needs to be performed only when the data in devices is inconsistent with that in the server due to objective factors, such as the Internet abnormality or other conditions.)

In the device list, select the area in which the devices with the data to be synchronized reside and click Device Data Synchronization to access the confirmation interface of data synchronization.

Click OK to reboot the device.

?Important tip: The operation of synchronizing the software data to the devices will delete existing data (excluding event records) in the devices at first and then re-download all setting information. It is essential to ensure a smooth Internet connection and avoid power failure during this operation.
