Muchirongwa cheCCTV chekutarisa system, isu kazhinji tinoda kushandisa vhidhiyo rekodha.Mhando dzinonyanya kuzivikanwa dzevhidhiyo rekodha iDVR neNVR.Saka, pakuisa, tinoda kusarudza DVR kana NVR.Asi unoziva here kusiyana kwacho?
DVR yekurekodha mhedzisiro inotsamira kumberi-kumagumo kamera uye iyo DVR's pachayo compression algorithm uye chip kugadzirisa kugona, nepo NVR yekurekodha mhedzisiro inotsamira zvakanyanya kumberi-kumagumo IP kamera, nekuti kubuda kweIP kamera idhijitari yakamanikidzwa vhidhiyo.Kana chiratidzo chevhidhiyo chasvika paNVR, haidi shanduko yeanalog-kune-digital uye kudzvanywa, ingochengeta, uye machipisi mashoma chete anodiwa kuti apedze hurongwa hwese.
DVR
DVR inonziwo dhijitari vhidhiyo rekodhi kana dhisiki rekodhi rekodhi.Isu taimboti hard disk recorder.Kana ichienzaniswa neyekare analog vhidhiyo rekodhi, inorekodha vhidhiyo mu hard disk.Iyo komputa sisitimu yekuchengetera mifananidzo uye kugadzirisa, ine kureba kwenguva refu vhidhiyo, kutarisa kure uye kutonga mufananidzo / izwi mabasa.
DVR ine akati wandei mabhenefiti, kana ichienzaniswa neyechinyakare analog yekutarisa masisitimu.DVR inoshandisa tekinoroji yekurekodha yedhijitari, iyo iri nani kupfuura analogi maererano nemhando yemufananidzo, kuchengetedza, kutora, kuchengetedza, uye kutapurirana network.Mukuwedzera, DVR iri nyore kushanda pane analog systems, uye inotsigira kure kure.
NVR
IP makamera ave kuwedzera mukurumbira mumakore achangopfuura, sezvo aine akati wandei mabhenefiti pane echinyakare CCTV kamera.Imwe yemabhenefiti makuru ndeyekuti ivo vanogona kubatana kunetiweki, iyo inobvumira kutarisa kure, manejimendi uye nyore kuwedzera.
Zita rakazara reNVR itiweki vhidhiyo rekodhi, rakagadzirirwa kugamuchira, kuchengeta uye kutonga edhijitari vhidhiyo hova kubva kuIP kamera.Inofanirwa kubatanidza IP kamera, haigone kushanda yega.NVR ine mabhenefiti akati wandei pamusoro peDVR yechinyakare, kusanganisira kugona kuona uye kubata akawanda makamera panguva imwe chete, uye kugona kuwana makamera kure kure kubva chero kupi zvako munyika kuburikidza neEthernet.Saka ziva zvakanakira kugoverwa networking.
Kana uri kufunga kuisa IP kamera, saka NVR chinhu chakakosha chemidziyo.Ichakubvumidza iwe kutora mukana wakazara wezvakanakira IP makamera, uye ive nechokwadi chekuti system yako inoshanda zvizere uye yakachengeteka.
Musiyano uripo pakati peDVR neNVR
Musiyano mukuru pakati peDVR neNVR imhando yemakamera avanowirirana nawo.DVR inoshanda chete nemakamera eanalogi, nepo NVR inoshanda neIP kamera.Mumwe mutsauko ndewekuti maDVR anoda kuti kamera yega yega ibatanidzwe kuDVR uchishandisa coaxial tambo, nepo NVRs inogona kubatana ne IP kamera newireless transmission kana wired Ethernet tambo.
NVR inopa huwandu hwezvakanakira pamusoro peDVR.Kutanga, ivo vari nyore kwazvo kuseta uye kugadzirisa.Chechipiri, NVR inogona kurekodha pane yakakwirira resolution kupfuura DVR, saka iwe unowana zvirinani mhando yemufananidzo.Pakupedzisira, NVR inopa scalability iri nani pane DVR;unogona kuwedzera mamwe makamera nyore nyore kuNVR system, nepo DVR system ichiganhurwa nehuwandu hwematanho ekuisa paDVR.
