 2.  Compile the product solution.
 
-    The configuration of the product solution is stored in a JSON file \(for example,  **ipcamera\_hi3516dv300.json**\) under the  **build/lite/product**  directory. During the construction, the system reads the configuration file, which contains custom subsystems and components. To compile  **ipcamera\_hi3516dv30**, for example, run the following command:
