在 OpenClaw 中安装
/install node-camera
功能描述
控制 Node 设备的 USB 摄像头，支持单帧截图、流式推送、停止推流和关闭摄像头。使用场景：(1) 需要快速获取 Node 设备的一帧图像时，(2) 需要远程监控 Node 设备周围环境时，(3) 需要进行视觉识别或拍照截图时。
安全使用建议
This skill appears to do what it says: control a Node device USB camera and provide JPEG URLs. Before installing, consider privacy and network exposure: image URLs are served from the device HTTP server (http://<deviceIP>:18790), so ensure the device is on a trusted network and the HTTP endpoint is not publicly reachable. Only use with devices you control and with camera/storage permissions intentionally granted. Validate any device IP/URL before downloading images and avoid exposing image URLs or device IPs to untrusted parties.
功能分析
Type: OpenClaw Skill
Name: node-camera
Version: 1.0.1
The node-camera skill provides legitimate functionality for capturing and streaming images from a USB camera connected to an Android Node device. The SKILL.md documentation clearly defines commands for frame capture and streaming, while the scripts/camera_helper.py utility provides standard helper functions for downloading and decoding image data without any evidence of malicious intent or unauthorized data exfiltration.
能力评估
Purpose & Capability
The name/description describe camera capture and streaming; the SKILL.md instructs using the OpenClaw gateway to invoke camera commands and exposes image URLs on the device HTTP server. The included helper script only downloads images, decodes base64 frames, and analyzes frame JSON—functions coherent with the stated purpose.
Instruction Scope
Runtime instructions limit actions to invoking camera commands (captureFrame, open, stopStreaming, close) and retrieving JPEGs from the device's HTTP server. The SKILL.md does not instruct reading unrelated host files, environment variables, or sending data to external endpoints other than the device's embedded HTTP server.
Install Mechanism
No install spec is present (instruction-only). The repository includes a small, readable Python helper; there are no downloads from third-party URLs or archive extraction steps. Risk from installation is minimal.
Credentials
The skill declares no required environment variables, credentials, or config paths. The operations described (HTTP URLs served by the Node device and gateway invocations) do not require host secrets, so requested access is proportionate.
Persistence & Privilege
always is false and the skill does not request persistent system privileges or modify other skills. Autonomous invocation is allowed (platform default) but the skill does not request elevated persistence or system-wide changes.
如何使用
- 确保已安装 OpenClaw（本地或 Docker 部署）
- 在对话框中输入安装命令：
/install node-camera - 安装完成后，直接呼叫该 Skill 的名称或使用
/node-camera触发 - 根据 Skill 的参数说明提供必要输入，即可获得结构化输出
版本历史
v1.0.1
**v1.0.1 — 图片结果由 Base64 改为 URL，采用 Node 设备本地 HTTP 服务器访问**
- 截图与视频帧结果由内联 Base64 编码图片改为 HTTP URL（如 http://设备IP:18790/images/xxx.jpg）
