Kwiprojekthi yenkqubo yokucupha yeCCTV, sihlala sifuna ukusebenzisa isishicileli sevidiyo.Ezona ntlobo zixhaphakileyo zokurekhoda ividiyo yi-DVR kunye ne-NVR.Ke, xa ufaka, kufuneka sikhethe i-DVR okanye i-NVR.Kodwa ngaba uyazi ukuba yintoni umahluko?
Isiphumo sokurekhoda kwe-DVR sixhomekeke kwikhamera ye-front-end kunye ne-algorithm yoxinzelelo lwe-DVR kunye nezakhono zokucwangcisa i-chip, ngelixa isiphumo sokurekhoda se-NVR sixhomekeke kakhulu kwikhamera ye-IP yangaphambili, kuba imveliso yekhamera ye-IP yividiyo ecinezelweyo yedijithali.Xa umqondiso wevidiyo ufikelela kwi-NVR, ayifuni ukuguqulwa kwe-analog-to-digital kunye noxinzelelo, gcina nje, kwaye kuphela iitshiphusi ezimbalwa ezifunekayo ukugqiba yonke inkqubo.
DVR
I-DVR ikwabizwa ngokuba yirekhoda yevidiyo yedijithali okanye irekhoda yedisk yedijithali.Sasidla ngokuyibiza ngokuba yihard disk recorder.Xa kuthelekiswa nerekhodi yevidiyo ye-analog yemveli, irekhoda ividiyo kwidiski enzima.Yinkqubo yekhompyuter yokugcinwa kwemifanekiso kunye nokusebenza, kunye nokurekhoda kwevidiyo ixesha elide, ukubeka iliso kude kunye nokulawula umfanekiso / imisebenzi yezwi.
I-DVR ineenzuzo ezininzi, xa kuthelekiswa neenkqubo zokucupha ze-analog zemveli.I-DVR isebenzisa itekhnoloji yokurekhoda yedijithali, engaphezulu lee kune-analog ngokomgangatho womfanekiso, umthamo wokugcina, ukufunyanwa, ukugcina, kunye nokuhanjiswa kwenethiwekhi.Ukongeza, i-DVR ilula ukusebenza kuneenkqubo ze-analog, kunye nenkxaso yokulawula kude.
NVR
Iikhamera ze-IP ziye zanda kakhulu kwiminyaka yakutshanje, njengoko zinenani leenzuzo ngaphezulu kweekhamera zeCCTV zemveli.Enye yeenzuzo eziphambili kukuba zinokudityaniswa kwinethiwekhi, evumela ukujonga kude, ukulawula kunye nokwandisa lula.
Igama elipheleleyo le-NVR sisirekhoda sevidiyo yenethiwekhi, yenzelwe ukufumana, ukugcina nokulawula imijelo yevidiyo yedijithali evela kwiikhamera ze-IP.Kufuneka idinge ukudibanisa iikhamera ze-IP, ayikwazi ukusebenza yodwa.I-NVR inenani leenzuzo ngaphezu kwe-DVR yendabuko, kuquka ukukwazi ukujonga nokulawula iikhamera ezininzi ngexesha elinye, kunye nokukwazi ukufikelela kude kwiikhamera ukusuka naphi na kwihlabathi nge-Ethernet.Ngoko ke qaphela inzuzo yokusasazwa kwenethiwekhi.
Ukuba ucinga ngokufaka iikhamera ze-IP, ke i-NVR sisixhobo esibalulekileyo.Kuya kukuvumela ukuba usebenzise ngokupheleleyo inzuzo yeekhamera ze-IP, kwaye uqinisekise ukuba inkqubo yakho isebenza ngokupheleleyo kwaye ikhuselekile.
Umahluko phakathi kwe-DVR kunye ne-NVR
Umahluko omkhulu phakathi kwe-DVR kunye ne-NVR luhlobo lweekhamera ezihambelana nazo.I-DVR isebenza kuphela ngeekhamera ze-analog, ngelixa i-NVR isebenza ngeekhamera ze-IP.Omnye umehluko kukuba i-DVR ifuna ukuba ikhamera nganye idibaniswe ne-DVR isebenzisa intambo ye-coaxial, ngelixa i-NVRs inokuxhuma kwiikhamera ze-IP nge-wireless transmission okanye i-wire Ethernet cable.
I-NVR ibonelela ngenani leenzuzo ngaphezulu kwe-DVR.Okokuqala, kulula kakhulu ukuseta kunye nokuqwalasela.Okwesibini, i-NVR inokurekhoda kwisisombululo esiphezulu kune-DVR, ngoko uya kufumana umfanekiso ongcono.Ekugqibeleni, i-NVR inikezela nge-scalability engcono kune-DVR;unokongeza ngokulula ngakumbi iikhamera kwi-NVR inkqubo, ngelixa inkqubo ye-DVR inqunyelwe linani lamatshaneli okufaka kwi-DVR.
