  Single sensor cameras

  The Dallmeier 5000 series single sensor cameras come with a new encoder. The new versions of the dome, IR and fisheye cameras support H.265 HEVC (High Efficiency Video Coding) and offer the improved object classification with camera-based, AI-enhanced VCA (video content analysis).

  By its nature, the constantly improving resolution of video images demands high bandwidths and large amounts of memory. With the new H.265 encoder in these cameras, data rate can be reduced by up to half it is claimed compared with an H.264 stream without the makers add sacrificing resolution or image quality. When used with the latest Dallmeier recording systems, a significant reduction in network and memory capacity can be achieved, the firm says.

  As for the video content analysis, neural networks in the camera support the classic VCA and thus enable more efficient object classification in the camera it is claimed. After a short learning phase, the system is capable of delivering still more precisely defined analysis of the recordings and more effective use of automatic video analysis functions such as lossless and multiple auto tracking, according to the firm.

  單傳感器攝像機

  Dallmeier 5000系列單傳感器攝像機具有新的編碼器。新型球機,紅外攝像機和魚眼鏡頭攝像機支持H.265 HEVC(高效視頻編碼),并且提供通過基于攝像機的AI增強VCA(視頻內容分析)。

  從本質上講,視頻圖像分辨率的不斷提高依靠高帶寬和大內存。借助這些攝像機中的新型H.265編碼器,與H.264流相比,可以將數據速率降低多達其聲稱的一半,而無需制造商犧牲分辨率或圖像質量。該公司表示,與最新的Dallmeier記錄系統一起使用時,可以大大減少網絡和內存容量。

  對于視頻內容分析,攝像機中的神經網絡支持經典的VCA,因此可以在攝像機中實現更有效的對象分類。在短暫的學習階段之后,該系統能夠對錄音進行更加精確定義的分析,并能夠更有效地利用自動視頻分析功能,例如無損和多自動跟蹤。
