Iinkqubo zokhuseleko ezisekwe kwikhamera ye-IP ziye zazisa izibonelelo ezininzi ezintsha kwintengiso ukusukela oko zaziswayo, kodwa uphuhliso alusoloko luhamba kakuhle. Kangangamashumi eminyaka, abaqulunqi bevidiyo bejongana nemiba yokuhambelana nezixhobo.
Iprotocol eyodwa yamazwe ngamazwe yayifanele ixazulule le ngxaki ngokudibanisa iimveliso ezivela kubakhiqizi abahlukeneyo ngaphakathi kwenkqubo enye, kubandakanywa iikhamera ze-PTZ ezikhawulezayo, izixhobo ezineelensi ze-varifocal kunye ne-zoom lens, i-multiplexers, kunye neerekhodi zevidiyo zenethiwekhi.
Nangona kunjalo, ukuza kuthi ga ngoku, iiprothokholi zemveli zabenzi bezixhobo zevidiyo zihlala zifanelekile. Nakwisixhobo seBridgen se-Ivideon, esikuvumela ukuba uqhagamshele β98% yeentlobo zekhamera kwilifu, sibonelela ngezakhono ezikhethekileyo xa usebenza ngeeprothokholi zomthonyama.
Kutheni le nto yenzekile kwaye zeziphi iingenelo zeprothokholi zomthonyama, siya kuchaza ngakumbi sisebenzisa umzekelo wokudityaniswa neDahua Technology.
Umgangatho omnye
Ngokomlando, ukudala eyona nkqubo isebenzayo edibanisa izisombululo ezigqwesileyo ezivela kwinani labathengisi kuye kwafuna umsebenzi omkhulu wokudibanisa.
Ukucombulula ingxaki yokungahambelani kwezixhobo, umgangatho we-Open Network Video Interface Forum waphuhliswa kwi-2008. I-ONVIF ivumele abaqulunqi kunye nabafakeli ukuba banciphise ixesha elichithwe ukuseta onke amacandelo enkqubo yevidiyo.
Abadibanisi benkqubo kunye nabasebenzisi bokugqibela bakwazile ukugcina imali besebenzisa i-ONVIF ngenxa yokhetho lwasimahla lwawo nawuphi na umenzi xa ulinganisa inkqubo okanye ngokuyinxenye ukubuyisela amacandelo ngamanye.
Ngaphandle kwenkxaso ye-ONVIF kubo bonke abavelisi bezixhobo zevidiyo ezikhokelayo, phantse yonke inkampani enkulu isenayo iprotocol yemveli kwikhamera nganye kunye nerekhoda yevidiyo yomenzi.
I-Dahua Tech inezixhobo ezininzi ezixhasa zombini i-onvif kunye ne-proprietary ye-Dahua yangasese yeprotocol, esetyenziswa nguDahua ukwakha iinkqubo zokhuseleko ezinzima ngokusekelwe kwizixhobo zayo.
Iiprothokholi zomthonyama
Ukungabikho kwayo nayiphi na imiqobo yinzuzo yophuhliso lwemveli. Kwimisebenzi eyakhelweyo, umenzi ugxininisa kwezo "mpawu" ezizijonga njengezona zibalulekileyo, ezixhasa zonke izakhono ze-hardware yayo.
Ngenxa yoko, iprotocol yomthonyama inika umenzi ukuzithemba ngakumbi ekusebenzeni kunye nokhuseleko lwesixhobo, njengoko iqinisekisa ukusebenza kakuhle kokusetyenziswa kwezixhobo zehardware.
Oku akusoloko kukuhle - kwaye inani elikhulu leekhamera ezivela kwi-Aliexpress ezisebenza zisebenzisa "ezivuzayo" kunye neeprothokholi ezivulekileyo, "ezibonisa" ukugcwala kwihlabathi liphela, bubungqina obucacileyo boku. Ngabavelisi abafana neDahua Technology, abanokukwazi ukuvavanya iinkqubo zokukhusela ixesha elide, imeko iyahluka.
Iprotocol yekhamera ye-IP yomthonyama ivumela inqanaba lodibaniso olungafezekiyo nge-ONVIF. Umzekelo, xa uqhagamshela ikhamera ehambelana ne-ONVIF kwi-NVR, kufuneka ufumane isixhobo, udibanise, kwaye uvavanye ukusebenza ngexesha langempela. Ukuba ikhamera "inxibelelana" isebenzisa iprotocol yendalo, ngoko ifunyenwe kwaye iqhagamshelwe kwinethiwekhi ngokuzenzekelayo.
Ngamanye amaxesha xa usebenzisa irekhoda enekhamera yomntu wesithathu, unokuqaphela ukuhla komgangatho wemifanekiso. Xa usebenzisa iiprothokholi zomthonyama zezixhobo ezivela kumenzi ofanayo, le ngxaki, ngokomgaqo, ayiveli naxa uthumela umqondiso kwintambo ukuya kuthi ga kwi-800 yeemitha (kunye ne-Extended Power over Ethernet technology).
Le teknoloji yenziwa kwaye yaziswa yiDahua Technology. I-ePoE (i-Power over Ethernet) iteknoloji inqoba umda we-Ethernet yendabuko kunye ne-POE (zombini zikhawulelwe kwiimitha ezili-100 phakathi kwamachweba othungelwano) kwaye ziphelise imfuno yezixhobo ze-PoE, izandiso ze-Ethernet, okanye ukutshintshwa kwenethiwekhi ezongezelelweyo.
Ukusebenzisa i-2D-PAM3 i-encoding modulation, iteknoloji entsha ihambisa amandla, ividiyo, i-audio kunye neempawu zokulawula kwimigama emide: ngaphezu kweemitha ze-800 kwi-10 Mbps okanye i-300 yeemitha kwi-100 Mbps nge-Cat5 okanye i-coaxial cable. I-Dahua ePoE yinkqubo yokucupha ividiyo eguquguqukayo ngakumbi kwaye inokuthenjwa kwaye ikuvumela ukuba ulondoloze ukufakela kunye neengcingo.
Ukudityaniswa neDahua Technology
Ngo-2014, i-Ivideon yaqala ukusebenzisana nenkampani , engomnye wabenzi bezixhobo zevidiyo ezikhokelayo kwihlabathi, Isabelo sesibini ngobukhulu kwimarike yeenkqubo zokhuseleko zehlabathi. Ngoku eDahua indawo yesibini kuluhlu lweenkampani ezineentengiso ezinkulu ze-a&s zoKhuseleko 50.
Ukusebenzisana ngokusondeleyo kweenkampani zethu kwenze ukuba kube lula ukuphumeza ukudityaniswa kwezixhobo ezininzi zezixhobo, ukulinganisa amawaka eemodeli zeekhamera zenethiwekhi kunye neerekhodi zevidiyo.
Ngo-2017, siphuhlise isisombululo esikuvumela ukuba udibanise ikhamera ye-analog esemgangathweni kunye nenkcazo ephezulu kwilifu usebenzisa.
Siphinde sakwazi ukubonelela ngoomatshini abalula bokudibanisa naliphi na inani leekhamera zeDahua kwilifu, kungakhathaliseki ukuba yiphi indawo, ngaphandle kokusebenzisa ii-DVR, iiPC okanye isoftware eyongezelelweyo.
Ngo-2019, sibe ngamaqabane anobuchule kwi-DIPP () - inkqubo yentsebenziswano yeteknoloji ejolise kuphuhliso oludibeneyo lwezisombululo ezinzima ezidibeneyo, kubandakanywa nezisombululo zohlalutyo lwevidiyo. I-DIPP ibonelela ngoyilo oluphambili kunye nenkxaso yobugcisa kwiimveliso ezidibeneyo.
Inkxaso kaDahua kuzo zonke izigaba zokudala iimveliso ezintsha zisivumele ukuba sisebenzisane neprotocol yendalo kwizisombululo ezahlukeneyo. Esinye sezixhobo ezinomdla kakhulu zonyaka ophelileyo , apho sakwazi ukufezekisa ukuhambelana neekhamera zeDahua kwinqanaba lesixhobo sabo "somthonyama".
Ikhokelela phi βibhulorhoβ?
Ibhulorho yigajethi elingana nomzila omncinci we-Wi-Fi. Le bhokisi ikuvumela ukuba udibanise ukuya kwiikhamera ze-16 zalo naluphi na uhlobo kwilifu le-Ivideon. Oku kuthetha ukuba abasebenzisi beenkqubo zendawo bafumana ukufikelela kwinkonzo yefu ngaphandle kokutshintsha izixhobo ezifakiweyo. Unokongeza iikhamera ze-analog efini ngerekhoda yevidiyo eqhagamshelwe kwi-Ivideon Bridge.
Iindleko zesixhobo namhlanje zingama-ruble angama-6. Ngokumalunga nexabiso / umlinganiselo wesiteshi, iBridge ibe yindlela enenzuzo kakhulu yokudibanisa kwifu ye-Ivideon: ishaneli enye eneBridge ene-archive ehlawulwayo yokugcina isiseko esivela kwi-Ivideon iya kubiza i-ruble ye-000. Ukuthelekisa: xa kuthengwa ikhamera ngokufikelela kwifu, iindleko zeshaneli enye ziya kuba ngama-ruble angama-375.
I-Ivideon Bridge ayisiyiyo nje enye i-DVR, kodwa isixhobo seplagi kunye nokudlala esenza lula kakhulu ulawulo olukude ngelifu.
Enye yezinto ezinomdla "kwibhulorho" yinkxaso epheleleyo yeprotocol yaseDahua. Ngenxa yoko, iBridge iye yatyetyiswa ngemisebenzi enefuthe elithe ngqo ekusebenzeni kweenkqubo zokucupha ividiyo.
Iimpawu zeBridge zemveli kunye neqonga elinqamlezayo
Ukurekhoda idatha yendawo
Imowudi yokusebenza ye-Edge Storage iyafumaneka kuzo zonke iikhamera zeDahua kunye nee-DVR eziqhagamshelwe ngeBridge usebenzisa iprotocol yendalo. I-Edge ikuvumela ukuba urekhode ividiyo ngokuthe ngqo kwimemori khadi yakho yangaphakathi okanye iNAS. Ugcino lwase-Edge lubonelela ngezi zixhobo zilandelayo zokurekhoda eziguquguqukayo:
- ukugcina inethiwekhi kunye nemithombo yogcino;
- ukunatyiswa ngokupheleleyo kogcino lwedatha;
- ukwandisa ukusetyenziswa kwe-bandwidth;
- ukwenza i-backup ye-archive kwimeko yokusilela koqhagamshelwano;
- ukugcinwa kwi-archive yefu: kwanele ukufaka isicwangciso somrhumo omncinci - umzekelo, ixabiso elincinci lonyaka kwiikhamera ze-8 efini liya kuba yi-ruble ye-1 kuphela / inyanga okanye i-ruble ye-600 / ngonyaka.
Ifumaneka kuphela ngeprotocol yendalo, imowudi ye-Edge sisisombululo sokurekhoda esixubileyo, kwelinye icala, sinciphisa iingozi zoshishino ezinxulumene nokulahleka koxhulumaniso ngokukhawuleza, kwaye ngakolunye uhlangothi, ikuvumela ukuba ulondoloze kwiindleko eziphezulu zezithuthi.
Ukuseta i-OSD kunye ne-backlight
I-Ivideon Bridge ibonelela ngokufikelela ekusetezeni ukwaleka kwesicatshulwa esinesizathu, umhla kunye nexesha kumfanekiso (kwiSiboniso seSkrini, i-OSD).
Njengoko utsala, umbhalo kunye nomhla amanqaku "ncamathela" kwigridi engabonakaliyo. Le gridi yahlukile kwikhamera nganye, kwaye kuxhomekeke kwindawo ekuyo umfanekiso ileyibhile, indawo yokwenyani yombhalo ogqunyiweyo ingabalwa ngokwahlukileyo.
Xa ucima umbhalo okanye umhla wokwaleka, useto lwazo luyagcinwa, kwaye xa ululayita, luyabuyiselwa.
Izicwangciso ezikhoyo kwikhamera ethile zixhomekeke kwimodeli yayo kunye nenguqulo ye-firmware.
Iiparameters zokusebenza ze-motion detector
Inkqubo ikuvumela ukuba utshintshe ngobuntununtunu iiparamitha zokusebenza zesikhangeli sentshukumo, ukuquka ukuseta indawo yobhaqo engenamkhethe.
Ukutshintsha iiparamitha zomjelo wevidiyo
Ukulungelelanisa iiparamitha zevidiyo kunye nemijelo yeaudiyo kuya kunceda ukunciphisa umthwalo kwisitishi se-Intanethi - "ungasika" inani lamaxabiso kwaye ugcine kwitrafikhi.
Ukuseta imakrofoni
Njengokusasazwa kwevidiyo, useto lwemakrofoni lubonelela ngokufikelela kwisikali sobuntununtunu ekuvumela ukuba wenze ngcono ukusetyenziswa kwesixhobo ngaphakathi kumagumbi anengxolo.
isiphelo
Ibhulorho sisixhobo sendalo yonke esinamandla okuqwalasela ubuchwephesha bonxibelelwano lwekhamera. Le modi iya kufuneka ukuba uceba ukudibanisa irekhoda endala okanye ikhamera kwilifu elingenakubonwa ngokuzenzekelayo.
Ngenxa yokuguquguquka kwezicwangciso zeBridge, umsebenzisi unokumelana ngokulula neemeko xa idilesi ye-IP, ukungena kwekhamera / igama lokugqithisa, okanye isixhobo sitshintshwa. Ngokutshintsha ikhamera, awuyi kuphulukana nogcino lwevidiyo olurekhodiweyo ngaphambili efini kunye nobhaliso olusele luhlawulwe kwinkonzo.
Kwaye nangona iBridge ikuvumela ukuba usebenze kunye ne-ONVIF kunye ne-RTSP kwinqanaba leengcali, ngaphandle kokukhathala komsebenzisi "ngexesha lokuqala kwi-Boeing cockpit" izicwangciso zenqanaba, eyona "imbuyekezo" enkulu evela kwiikhamera inokuvakala ngokudibanisa okunzulu, njengoko kunokubakho. kubonakala kumzekelo wenkxaso yeprotocol yeDahua Technology.
