# Camera Remote Command SDK

> Sony's PTP-based SDK for direct camera commands

The Camera Remote Command SDK provides direct camera control using PTP (Picture Transfer Protocol) commands over USB. It supports both PTP-2 and PTP-3 protocols for sending operational commands to compatible Sony cameras.

## How It Differs from Camera Remote SDK

|                      | Camera Remote SDK       | Camera Remote Command SDK   |
| -------------------- | ----------------------- | --------------------------- |
| **Protocol**         | Proprietary HTTP/USB    | PTP-2 / PTP-3               |
| **Languages**        | C++, C#                 | C++                         |
| **Abstraction**      | High-level API          | Low-level PTP commands      |
| **Use Case**         | Application development | Custom protocol integration |
| **Camera Discovery** | Built-in                | Manual PTP enumeration      |

The Camera Remote SDK is recommended for most application development. The Camera Remote Command SDK is intended for developers who need direct PTP-level control or are integrating with existing PTP-based workflows.

## Key Capabilities

* **PTP-2 Commands** — Standard Picture Transfer Protocol operations
* **PTP-3 Commands** — Extended protocol with additional camera control features
* **Direct USB Control** — Low-level USB communication without abstraction layers
* **Custom Workflows** — Build specialized capture pipelines with precise timing control
