The Line Camera module in安卓 devices does not include a VPN for the following reasons:

1. Functionality-Driven Encryption: Line Cameras are designed for specific use cases (e.g., live video calls, streaming) and do not require encryption for these functions, as they capture data without needing internet access.

2. Device Capabilities: The device itself may not support encryption for certain media or settings, and encryption is typically handled at the point of connection, not on the device's end.

3. Software Configuration: Encryption settings may be managed by the device's operating system, which handles encryption rather than requiring a dedicated VPN.

In summary, the Line Camera module is lightweight and designed to handle specific functionalities without needing encryption, which is typically managed by the device's software or network settings.
