### 实机验收完善（v0.1.20）
摄像机信息及参数改为紧凑布局；全屏监控隐藏管理参数入口。读取或保存时暂时锁定参数输入，避免正在编辑的值被返回结果覆盖。视频服务错误响应也会正确关闭，修复新 Python 版本提示的资源未释放问题。
## 云台常用位置、截图与录像续播（v0.1.21）
- “云台控制”中读取设备预置位。管理员可以保存当前位置、删除位置；有对应空间与云台权限的个人账号可以查看和转到已有位置。保存和删除前检查版本，保存后回读设备列表。位置保存在摄像机中，双镜头可能共用同一云台。名称最多 40 字。本版不提供覆盖已有位置：实测 H9c 当前固件拒绝标准更新请求，调整后可另存新位置，再由管理员决定是否删除旧位置。
- 云台操作按物理设备 / 节点互斥。预置位转动后查询设备状态，观察窗口为 10 秒，单次设备请求另有 5 秒超时；结束、超时或异常都尝试发送 Stop。停止按钮不排队，可取消正在等待的转动。设备网络失联时无法保证 Stop 送达，界面会明确提示核对画面。关闭面板或切换后台时，对正在执行的操作尝试停止。预置位位置和设备能力仍以具体型号、固件实际返回为准。
- 实时画面与录像回放增加“截图”。截取当前播放器已解码的一帧，可预览并下载 PNG。图片仅在当前浏览器内存中生成，不上传到服务器，关闭后释放。截图分辨率取决于当前预览码流；截取时间不是摄像机源时间，仍有播放缓冲延迟。
- 本机录像查询按所选日期裁剪、排序与合并重叠范围。每次转换最多一小时，播放结束可以继续下一段；真实空档会跳过并提示。可取消自动续播。未正常播完的片段不会自动略过，主动暂停不会触发续播。
- 录像页显示实际录像时间，支持以当前播放位置标记片段起止、手动修改起止时间、生成原始编码下载链接。片段最长一小时，不能跨越无录像空档；边界受原始关键帧影响，非逐帧无损剪辑。自动续播保留正在填写的自定义片段。
- 本版不创建新的家庭数据或修改已有账户和录像策略；新增界面及设备操作继续使用既有空间、管理与云台权限。录像机原有历史录像仍未适配，以上续播与片段工具用于小电脑本机录像。
预置位协议依据：[ONVIF PTZ Service 5.4](https://www.onvif.org/specs/srv/ptz/ONVIF-PTZ-Service-Spec.pdf)。自动回归包含权限、并发、版本冲突、设备拒绝或未确认写入、停止、回放空档、日期边界和退出账号后的异步响应清理；模拟设备测试不代表所有品牌均已实机验证。
