Video Technology
采集 → 傳輸 → 錄影監看 → 邊緣事件 → 事後智能。環景與研判邊界寫清楚。
Capture — fixed and mobile front ends
固定與移動前端，把現場收進來 — 黑光鏡頭模組與智能肩咪等前端對應固定／半固定與移動采集；多鏡校正為事件後環景預留重疊視角。畫面依安裝與距離而定。
Black-light modules and smart shoulder mics cover fixed and mobile capture; multi-cam calibration reserves overlap for post-event panoramic replay.
Transport — aggregate, catch up, secure
匯流、補傳與安全組網 — 無線匯流閘道把移動前端匯流出站；影像補傳閘道在頻寬不穩時暫存再續傳對帳；安全組網支援無固定 IP 的遠端維運。不承諾零遺失。
Wireless aggregation gateways consolidate mobile front ends; video catch-up gateways buffer and reconcile when links fail; secure networking enables remote ops without fixed public IPs.
Recording & monitoring — evidence, broadcast, CMS
錄影、廣播與監看中心 — 影像中樞整理多路準備；錄影主機／現場智錄留下證據；影像廣播提供可點開連結與隱私派生流；監看中心（Windows／Mac／Web）管權限、牆面與回放。
The video hub prepares channels; recorders keep evidence; video broadcast issues shareable links and privacy streams; Monitoring Center handles roles, walls and playback—not panoramic replay itself.
Edge events — detect close to the camera
事件在現場先發生 — 現場智錄依規則做低延遲偵測（入侵、徘徊、進球、ROI 等）並輸出快照／短片；事件通知推到通訊軟體。大型語意說明留給事後，非每路每幀硬塞。
On-site smart recording runs rule-based low-latency detection and emits snapshots or clips; event notify pushes to messaging apps. Large language-style explanation stays post-event.
Post-event — panoramic replay & review (with boundaries)
環景回放與智能研判（有邊界） — 環景回放＝事件後離線多鏡重建，可旋轉看合成視角，非整場即時 360°。智能研判針對代表幀說明與複核；知識問答限已導入文件。皆事件驅動，非全時重算、非保證判決。
Panoramic replay is offline, post-event multi-cam reconstruction—not live full-site 360°. Intelligent review explains representative frames and supports Q&A within imported documents.
