I-Network Video Recorder 4K

I-Network Video Recorder 4k, ebizwa nangokuthi i-NVR 4K / 4K HD NVR / 4K NVR KIT / NVR 4CTV / NVR CCTV / NVR CCTV / NVR CCTV / NVR 4CK uhlelo lwe-4K, 4096X2160, cishe amaphikseli angama-8.8 angafinyelela i-movie Ikhwalithi Yezithombe Zezinga, elilingana nezikhathi ezingaphezu kwezine inani eliphakeme lamanje le-1080P lesisombululo. Ngokuqondene ne-4K, ivolumu yedatha yohlaka ngalunye selufinyelele ku-50MB, ngakho-ke kokubili ukudlala okukhohlisayo nokuhlelwa kudinga imishini yokucushwa kwezinga eliphezulu okusho nokuxazululwa kwencazelo ephezulu nentengo ephezulu.

Ngakho-ke luyini uhlaka?
Uhlaka luyingxenye encane kunazo zonke yesithombe esisodwa kuvidiyo / izithombe, ezilingana nohlaka lwelensi yefilimu. Uhlaka luyisithombe esisekhona, kanye namafreyimu alandelanayo akha izithombe, njengezithombe ze-TV. Imvamisa sibiza uHLELO Inombolo yamafreyimu adluliselwa izithombe ngomzuzwana owodwa. Futhi singabheka uhlaka ngokuthi iprosesa lehluzo lingavuselela kangaki ngomzuzwana, okuvame ukuvezwa yi- FPS (ozimele ngomzuzwana), futhi kungabizwa ngokuthi isilinganiso sohlaka. Uhlaka ngalunye luyisithombe esisekhona, futhi ozimele ababoniswayo ekulandeleleni okusheshayo bakha inkohliso yokunyakaza. Izinga lohlaka oluphakeme lungafinyelela izithombe ezibushelelezi futhi ezinengqondo. Amafreyimu amaningi ngomzuzwana (FPS) kukhona, okubushelelezi ukunyakaza okukhonjisiwe kuzoba .

Ngakho-ke lithini isilinganiso?
Izinga lohlaka, futhi libizwa ngokuthi imvamisa yefreyimu, livezwa kuHertz (Hz) futhi livame kakhulu (isilinganiso) sezithombe ze-bitmap (iyunithi likabani livela ngokuqhubekayo esibukweni. Leli gama lisebenza futhi kumafilimu, amakhamera wevidiyo, kanye nemidwebo yekhompyutha kanye nezinhlelo zokubamba izinyathelo.

Kuthiwani ngobudlelwano phakathi kwesilinganiso sohlaka nombono womuntu?

Ukuzwela kwesikhathi nokuxazululwa kombono wobuntu kuyahlukahluka, ngokusho kwezinhlobo nezimpawu zokukhuthaza okubukwayo , futhi kuhluka phakathi kwabantu. Uhlelo lokubona abantu lungacubungula izithombe eziyi-10 kuye kwezingu-12 ngomzuzwana futhi lubabone ngawodwana, futhi amanani aphezulu ozimele abhekwa njengezinyathelo.

Ngokuvamile, lapho isilinganiso sefreyimu siphakeme kune-50 hz kuya ku-90 hz, ababambiqhaza abaningi ocwaningweni bakholelwa ukuthi ukukhanya okulungisiwe (okufana nokuqina kwekhompyutha) kubizwa ngokuthi yilesi sibani esinqunyiwe kubizwa ngokuthi umkhawulo we-flicker fusion ( Lapho ukukhanya okulungisiwe kungafani futhi kuqukethe isithombe, umkhawulo we-Flicker Fusion ungaba ngaphezulu kakhulu, mhlawumbe amakhulukhulu kaHertz). Ngokuqondene nokuqashelwa kwesithombe, kutholakele ukuthi uma abantu bedinga ukubona izithombe ezithile ochungechungeni olungaphazanyiswa lwezithombe ezihlukile , isithombe ngasinye kufanele sihlale ama-millisecond okungenani. Futhi ukuphikelela kombono womuntu kwesinye isikhathi kungadala isisusa esibonakalayo esifushane se-millisecond esibonakalayo, kanti isikhathi sizosukela kuma-milliseconds angama-400 ama-millisecond afinyelela kuma-millisecond angama-400 . Kufushane kakhulu ukukhuthaza okuningi okuningi kubhekwa njengesikhuthazo esisodwa. Isibonelo, i-mile- millisecond green flash kuqala, kwalandela i-red ebomvu engu-10 millondis

Yebo, ngithemba ukuthi isingeniso sami nge-Network Video Recorder 4K kanye ne-Frame Fate ingakusiza wazi okuningi ngale nkambu yokuqapha ividiyo.
