Kuphrojekthi yesistimu yokugada ye-CCTV, ngokuvamile sidinga ukusebenzisa isiqophi sevidiyo.Izinhlobo ezivame kakhulu zokuqopha ividiyo yi-DVR ne-NVR.Ngakho, lapho ufaka, sidinga ukukhetha i-DVR noma i-NVR.Kodwa uyazi yini umehluko?
Umphumela wokurekhoda we-DVR uncike kukhamera engaphambili kanye nekhono lokucindezela le-DVR kanye nekhono lokucubungula i-chip, kuyilapho umphumela wokurekhoda we-NVR uncike kakhulu kukhamera ye-IP engaphambili, ngoba okukhiphayo kwekhamera ye-IP kuyividiyo ecindezelwe yedijithali.Uma isignali yevidiyo ifinyelela ku-NVR, ayidingi ukuguqulwa nokucindezelwa kwe-analog-to-digital, gcina nje, futhi kudingeka ama-chips ambalwa kuphela ukuze kuqedelwe yonke inqubo.
I-DVR
I-DVR ibizwa nangokuthi i-digital video recorder noma i-digital hard disk rekhoda.Sasivame ukuyibiza ngokuthi i-hard disk recorder.Uma kuqhathaniswa nerekhoda yevidiyo ye-analog yendabuko, iqopha ividiyo ku-hard disk.Iwuhlelo lwekhompiyutha lokugcina nokucutshungulwa kwezithombe, olunokurekhoda kwevidiyo yesikhathi eside, ukuqapha okukude nokulawula imisebenzi yesithombe/yezwi.
I-DVR inezinzuzo eziningi, uma iqhathaniswa nezinhlelo zokugada ze-analogi zendabuko.I-DVR isebenzisa ubuchwepheshe bokuqopha bedijithali, obuphakeme kakhulu kune-analogi ngokwekhwalithi yesithombe, umthamo wokugcina, ukubuyisa, ukwenza ikhophi yasenqolobaneni, nokudluliswa kwenethiwekhi.Ngaphezu kwalokho, i-DVR kulula ukuyisebenzisa kunezinhlelo ze-analog, futhi isekela isilawuli kude.
I-NVR
Amakhamera we-IP athandwa kakhulu eminyakeni yamuva, njengoba anezinzuzo eziningi ngaphezu kwamakhamera e-CCTV endabuko.Enye yezinzuzo eziyinhloko ukuthi zingaxhunywa kunethiwekhi, okuvumela ukubuka kude, ukuphatha kanye nokwandisa kalula.
Igama eligcwele le-NVR irekhoda yevidiyo yenethiwekhi, yakhelwe ukwamukela, ukugcina nokuphatha ukusakazwa kwamavidiyo edijithali kumakhamera we-IP.Kumelwe idinge ukuxhuma amakhamera we-IP, ayikwazi ukusebenza yodwa.I-NVR inenani lezinzuzo nge-DVR evamile, okuhlanganisa ikhono lokubuka nokuphatha amakhamera amaningi ngesikhathi esisodwa, kanye nekhono lokufinyelela amakhamera ukude ukusuka noma yikuphi emhlabeni nge-Ethernet.Ngakho qaphela inzuzo yokuxhumana okusatshalaliswayo.
Uma ucabanga ukufaka amakhamera we-IP, i-NVR iwucezu lwesisetshenziswa esibalulekile.Kuzokuvumela ukuthi usebenzise ngokugcwele izinzuzo zamakhamera we-IP, futhi uqinisekise ukuthi uhlelo lwakho lusebenza ngokugcwele futhi luvikelekile.
Umehluko phakathi kwe-DVR ne-NVR
Umehluko omkhulu phakathi kwe-DVR ne-NVR uhlobo lwamakhamera ahambisana nawo.I-DVR isebenza kuphela ngamakhamera e-analog, kuyilapho i-NVR isebenza namakhamera we-IP.Omunye umehluko ukuthi ama-DVR adinga ukuthi ikhamera ngayinye ixhunywe ku-DVR kusetshenziswa intambo ye-coaxial, kuyilapho ama-NVR ekwazi ukuxhuma kumakhamera we-IP ngokudlulisela okungenantambo noma intambo ye-Ethernet enentambo.
I-NVR inikeza inani lezinzuzo kune-DVR.Okokuqala, kulula kakhulu ukusetha nokulungisa.Okwesibili, i-NVR ingaqopha ngokulungiswa okuphezulu kune-DVR, ngakho uzothola isithombe sekhwalithi engcono.Ekugcineni, i-NVR inikeza ukukala okungcono kune-DVR;ungakwazi ukwengeza kalula amakhamera engeziwe kusistimu ye-NVR, kuyilapho isistimu ye-DVR ilinganiselwe ngenani lamashaneli okokufaka ku-DVR.
