系統總覽該攝影機具有強大的光學變焦和精確的平移/傾斜/變焦性能，為戶外應用捕捉長距離視訊監控提供了一體化解決方案。與紅外線照明和星光技術相結合，該相機成為黑暗、低光應用的完美解決方案。該系列結合了日間/夜間機械紅外線截止濾光片，可在白天變化的照明條件下實現最高的影像品質。
功能星光科技
憑藉先進的影像處理技術和光學技術，大華星光技術可在低照度環境下提供清晰的彩色影片。廣泛適用於各種低照度環境。
防護等級（IP66、TVS 6000 V） IP66、TVS 6000 V 防雷、突波保護、電壓瞬變保護。
智能H.265+Smart H.265+ 是H.265 編解碼器的最佳化實現，它採用場景自適應編碼策略、動態GOP、動態ROI、靈活的多幀參考結構和智慧降噪功能，可在不影響視訊品質的情況下提供高品質視訊。
智慧型 H.265+ 技術優於標準 H.265 視訊壓縮，可將位元率和儲存要求降低多達 70%。
人臉偵測大華人臉偵測技術可以偵測影像中的人臉。該技術採用深度學習演算法，支援偵測、追蹤、捕捉和選擇最佳人臉影像，然後輸出人臉快照。
SMD 4.0大華智慧移動偵測技術結合智慧演算法，將觸發行動偵測警報的目標進行分類。它會過濾掉非目標物體，例如小型和大型動物，以避免觸發誤報。透過AI NVR，可以使用快速挑選技術，讓您可以輕鬆地從SMD事件影片中搜尋並挑選出人和車輛目標，並優先考慮匹配度最高的目標。
