title="視頻監(jiān)控">視頻監(jiān)控" title="視頻監(jiān)控">視頻監(jiān)控" title="視頻監(jiān)控">視頻監(jiān)控已普遍應用在人類生活環(huán)境的各個角落,安全監(jiān)控攝影機被安裝于個人住宅、小區(qū)街道、辦公大樓以及零售商店等各種不同地點。各種發(fā)展趨勢要求監(jiān)控系統(tǒng)在更長的時間內儲存更多的視頻數(shù)據(jù),視頻監(jiān)控攝影機的數(shù)量因而增加,再加上從標準分辨率到高分辨率的轉換以及法律制度的演變,種種原因都會提高整體運作成本。
目前安裝的新型監(jiān)控系統(tǒng),其儲存成本可占到總體安裝成本的 50%。令人震驚的是,在美國1PB (Petabyte)的企業(yè)級儲存成本約為 100 萬美元。更令人震驚的是,系統(tǒng)運作 4 年后,要維持相同儲存量的營運成本將比原始的
硬件成本高 4 倍。
儲存成本并非是視頻監(jiān)控使用者唯一關心的問題。從標準分辨率轉換至高分辨率的過程中,系統(tǒng)對帶寬與儲存的需求更提升 3倍之多。為了消除儲存限制,使用者可采用 H.264 編譯碼器等進階視頻壓縮技術。雖然執(zhí)行 H.264確實節(jié)省一些儲存空間,但由于高分辨率攝影機安裝的爆炸式增長,使得其所占優(yōu)勢已減低。
此外,法律程序對監(jiān)控視頻的接受度也逐漸提高,使得企業(yè)需能提供更長的影像存盤時間。
目前,大多數(shù)企業(yè)儲存監(jiān)控影像的期限為 30 天;不過,許多企業(yè)法律團隊都堅持應大幅延長儲存期限。目前在美國,個人傷亡信息儲存時效為 1 年。畢竟,影像信息若因儲存容量不足而被覆蓋,那么監(jiān)控系統(tǒng)的存在還有什
么價值呢?
視頻與影像技術的發(fā)展促使高分辨率攝影機成本不斷下降。
目前看到 1080p 視頻監(jiān)控攝影機已經(jīng)是很平常的事情了,而可支持比1080p分辨率高 10 倍的產(chǎn)品也正在開發(fā)之中,如此一來,將推動儲存需求增長 10 倍。此外,IMS Research 近期發(fā)布的一項預測報告表示,到 2012 年,將需要3.3 EB (exabytes) 的儲存容量來滿足新型視頻監(jiān)控的布建需求。
由于分析技術降低攝影機的監(jiān)控成本,因此視頻分析也為企業(yè)降低成本。自動化技術使企業(yè)能夠推出更多攝影機,但也對儲存技術帶來新的挑戰(zhàn)。
德州儀器 (TI) 了解未來監(jiān)控系統(tǒng)儲存需求已經(jīng)超過儲存容量技術的發(fā)展速度。為滿足大量視頻儲存的需求,TI 不斷研究能讓客戶輕松布建視頻監(jiān)控的低成本解決方案。因此,TI 推出具有整合視頻分析功能的DaVinci D M V A x 系列視頻處理器與智能編譯碼器技術 (Smart Codec Technology),此產(chǎn)品與技術的結合可將儲存與網(wǎng)絡帶寬的整體需求減少 50%。
目前,大多數(shù)監(jiān)控應用的標準方法是以指定分辨率與幀速率進行編碼并產(chǎn)生數(shù)據(jù)流,而不管攝影機畫面中正在進行的活動是什么,這種方法會占用大量儲存空間與網(wǎng)絡帶寬。為改善這種情況,高成本的高階攝影機已具有動作偵測功能
的視頻分析能力,只有在偵測到動作時才進行編碼并產(chǎn)稱數(shù)據(jù)流。然而,此方法的問題在于視頻分析并非萬無一失的,若某個重大事件沒有捕捉到,就可能造成嚴重后果,例如發(fā)生在人身傷害的法律訴訟案件中。
T I 憑借其 D M V A x 與智慧編譯碼器技術,能無時無刻地對監(jiān)控鏡頭進行編碼并不斷產(chǎn)生數(shù)據(jù)流,而其速率能滿足攝影機畫面內活動類型與活動量的需求。
就這種方法而言,不管現(xiàn)場是什么情況,攝影鏡頭都保持開啟狀態(tài),每天 24 小時、每周 7 天都會進行編碼并產(chǎn)生視頻流,而每個攝影機 30 天內平均需要 477GB(gigabytes) 的儲存空間。
在本例中顯示采用 TI DMVA2 與智慧編譯碼器技術的全新方法。
測試顯示:在 30% 的時間段中沒有出現(xiàn)達到預設標準的活動。因此,在采用 TI 智慧編譯碼器技術的情況下,該時間段的影像尺寸與幀速率都明顯地減少。一旦 DMVA2 的視頻分析偵測到達到預設標準的活動,就會在確保沒有訊框畫面被遺漏的情況下,持續(xù)動態(tài)地提高分辨率與幀速率。在本例中,TI 展示如何在確保監(jiān)控鏡頭連續(xù)性的同時,將儲存需求降低 25%。
擴大監(jiān)控系統(tǒng)后, 就如同2010 年上海世博會采用的 20 萬部高分辨率監(jiān)控攝影機,可節(jié)省高達 23.9 PB 的儲存空間。
過去,攝影機采用過動作偵測方案,有的還建立在視頻的基礎之上,但大多數(shù)這些解決方案都沒有針對特定的動作或活動,而是錄下一般性的任何動作,這
將大幅提升其編碼、數(shù)據(jù)流以及儲存的視頻量。此外,目前還沒有解決方案采用智能功能來做更有效的編碼控制,以及最大限度地儲存效率提升。
網(wǎng)絡帶寬與占用雖是次要問題,但TI 的解決方案也可為此問題帶來極大優(yōu)勢。透過將網(wǎng)絡上的數(shù)據(jù)數(shù)據(jù)最小化,可減少對儲存系統(tǒng)的需求,降低現(xiàn)有基礎架構的占用。這將對環(huán)境帶來正面的影響,因為數(shù)據(jù)中心 (data enter) 會消耗大量的能源。最新的McKinsey 報告顯示,到 2020 年,數(shù)據(jù)中心的二氧化碳排放量甚至將超過航空業(yè)2。
TI認為今后對更高分辨率監(jiān)控攝影機的需求可能還會持續(xù)增加,攝影機的安裝量與儲存需求也將大幅提升,這會是監(jiān)控系統(tǒng)解決方案今后必須要滿足與支持的方向,TIDMVAx 系列處理器配合 TI 智能編譯碼器技術為最佳的解決方案,將帶來解決問題的曙光。
