WizSense是大華股份推出的一系列採用自主人工智慧晶片和深度學習演算法的人工智慧產品和解決方案。它以高精度專注於人和車輛，使用戶能夠對定義的目標快速採取行動。 WizSense基於大華先進技術，提供智慧、簡單、普惠的產品和解決方案。
系統總覽憑藉強大的光學變焦和精確的平移和傾斜功能，PTZ 攝影機為大規模監控提供了一體化解決方案。它利用最新的星光技術，即使在低光源條件下也能產生高度細緻的影像。此攝影機控制流暢，防護等級高，能夠滿足中小場景視訊監控的需求。
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。
PFA技術PFA技術引入了新的判斷方法，確保了被攝體距離調整方向的準確性和可預測性。其結果是一套先進的對焦演算法，可確保變焦時的影像清晰度並縮短對焦時間。這使得相機的功能非常先進，大大提高了您的體驗品質。
寬動態範圍透過使用業界領先的寬動態範圍 (WDR) 技術，即使在高對比照明條件下，該相機也能產生生動的影像。對於在明亮和昏暗照明之間快速交替的場景，WDR 會進行調整以充分捕捉場景的明亮和黑暗區域，從而產生優質的視訊。
IVS大華IVS技術採用先進的視訊演算法，支援絆線、入侵等智慧功能。
防護等級（IP67，TVS 6000 V）IP67、TVS 6000V防雷、突波保護、電壓瞬變保護。
智能 H.265+ 和智能 H.264+大華智慧編碼技術採用先進的場景自適應碼率控制演算法，實現比H.265、H.264更高的編碼效率，提供高品質的視頻，降低儲存和傳輸成本。
