#  摄像头 ID 统一说明
# ============================================================
# 全系统的摄像头唯一标识统一叫 camera_code，格式为 cam_{hash}
# 不同系统的字段名映射关系：
#   - security-ai-edge:  camera_id   → 实际是 camera_code
#   - wvp-platform:      camera_code → 数据库字段就叫这个
#   - IoT 工单表:         camera_id   → 实际存的是 camera_code
#   - vsp-service:        device_id   → AlarmEvent 表，历史原因叫 device_id
#
# Python 代码中对外接口（API 参数、工具参数）统一使用 device_id，
# 因为 AlarmEvent 主表和 EdgeAlarmReport schema 已用此名。
# 内部传递和显示时，用 camera_name_service 解析为人类可读名称。
