Amasistimu okuphepha asekelwe kukhamera ye-IP alethe izinzuzo eziningi ezintsha emakethe kusukela yethulwa, kodwa ukuthuthukiswa bekungahlali kuhamba kahle. Sekungamashumi eminyaka, abaklami abaqapha amavidiyo bebhekene nezinkinga zokuhambisana nemishini.
Iphrothokholi eyodwa yamazwe ngamazwe kwakufanele ixazulule le nkinga ngokuhlanganisa imikhiqizo evela kubakhiqizi abahlukene ngaphakathi kwesistimu eyodwa, okuhlanganisa amakhamera we-PTZ anesivinini esikhulu, amadivayisi anamalensi e-varifocal namalensi okusondeza, ama-multiplexer, namarekhodi evidiyo enethiwekhi.
Kodwa-ke, kuze kube manje, izivumelwano zomdabu zabakhiqizi bemishini yevidiyo zisasebenza. Ngisho nasedivayisini ye-Ivideon Bridge, ekuvumela ukuthi uxhume β98% wezinhlobo zamakhamera efwini, sihlinzeka ngamakhono akhethekile lapho usebenza namaphrothokholi omdabu.
Kungani lokhu kwenzekile nokuthi yiziphi izinzuzo izivumelwano zomdabu ezinazo, sizoqhubeka sichaza sisebenzisa isibonelo sokuhlanganisa ne-Dahua Technology.
Indinganiso eyodwa
Ngokomlando, ukudala isistimu esebenza kahle kakhulu ehlanganisa izixazululo ezingcono kakhulu ezivela kubathengisi abambalwa kuye kwadinga inani elikhulu lomsebenzi wokuhlanganisa.
Ukuxazulula inkinga yokungahambisani kwemishini, izinga le-Open Network Video Interface Forum lathuthukiswa ngo-2008. I-ONVIF ivumele abaklami nabafakeli ukuthi banciphise isikhathi esichithwa simisa zonke izingxenye zesistimu yevidiyo.
Izihlanganisi zesistimu nabasebenzisi bokugcina bakwazile ukonga imali besebenzisa i-ONVIF ngenxa yokuzikhethela kwamahhala kwanoma yimuphi umkhiqizi lapho ekala isistimu noma eshintsha ingxenye yezingxenye ngayinye.
Naphezu kokusekelwa kwe-ONVIF okuvela kubo bonke abakhiqizi bemishini yevidiyo ephambili, cishe yonke inkampani enkulu isenayo iphrothokholi yomdabu yekhamera ngayinye nerekhoda yevidiyo yomkhiqizi.
I-Dahua Tech inamadivayisi amaningi asekela kokubili i-onvif kanye nephrothokholi yangasese ye-Dahua yokuphathelene, i-Dahua eyisebenzisayo ukwakha izinhlelo zokuphepha eziyinkimbinkimbi ngokusekelwe kumathuluzi ayo.
Izivumelwano zomdabu
Ukungabikho kwanoma yimiphi imikhawulo kuyinzuzo yentuthuko yendabuko. Emisebenzini eyakhelwe ngaphakathi, umkhiqizi ugxile kulezo "zici" ezizibheka njengezibaluleke kakhulu, zisekela wonke amakhono e-hardware yayo.
Ngenxa yalokho, iphrothokholi yomdabu inika umenzi ukuzethemba okwengeziwe ekusebenzeni nasekuvikelekeni kwedivayisi, njengoba iqinisekisa ukusebenza kahle okuphezulu ekusetshenzisweni kwezinsiza zehadiwe.
Lokhu akulungile ngaso sonke isikhathi - futhi inani elikhulu lamakhamera avela ku-Aliexpress asebenza kusetshenziswa izivumelwano "ezivuzayo" nezivulekile, "ezidalula" ithrafikhi emhlabeni wonke, kuwubufakazi obucacile balokhu. Ngabakhiqizi abanjengoDahua Technology, abangakwazi ukuhlola izinhlelo zokuvikela isikhathi eside, isimo sihlukile.
Iphrothokholi yekhamera ye-IP yomdabu ivumela izinga lokuhlanganisa elingafinyeleleki nge-ONVIF. Isibonelo, uma uxhuma ikhamera ehambisana ne-ONVIF ku-NVR, udinga ukuthola idivayisi, uyingeze, bese uhlola ukusebenza ngesikhathi sangempela. Uma ikhamera "ixhumana" isebenzisa umthetho olandelwayo womdabu, khona-ke iyatholwa futhi ixhunywe kunethiwekhi ngokuzenzakalelayo.
Kwesinye isikhathi uma usebenzisa irekhoda enekhamera yomuntu wesithathu, ungaqaphela ukonakala kwekhwalithi yesithombe. Uma usebenzisa amaphrothokholi omdabu kumadivayisi avela kumkhiqizi ofanayo, le nkinga, empeleni, ayiveli ngisho nalapho idlulisela isignali ngentambo efinyelela kumamitha angu-800 (ngamandla Anwetshiwe phezu kobuchwepheshe be-Ethernet).
Lobu buchwepheshe badalwa futhi bethulwa yi-Dahua Technology. Ubuchwepheshe be-ePoE (Amandla phezu kwe-Ethernet) bunqoba umkhawulo we-Ethernet yendabuko kanye ne-POE (kokubili okulinganiselwe kumamitha angu-100 phakathi kwamachweba enethiwekhi) futhi kuqeda isidingo samadivayisi we-PoE, izandisi ze-Ethernet, noma ukushintsha kwenethiwekhi okwengeziwe.
Kusetshenziswa ukuguqulwa kombhalo we-2D-PAM3, ubuchwepheshe obusha buletha amandla, ividiyo, amasiginali omsindo nokulawula ebangeni elide: ngaphezu kwamamitha angu-800 ku-10 Mbps noma amamitha angu-300 ku-100 Mbps nge-Cat5 noma ikhebula le-coaxial. I-Dahua ePoE iwuhlelo lokugada amavidiyo oluvumelana nezimo futhi oluthembekile futhi ikuvumela ukuthi wonge ekufakeni nasekufakeni izintambo.
Ukuhlanganiswa neDahua Technology
Ngo-2014, i-Ivideon yaqala ukusebenzisana nenkampani , okungenye yabakhiqizi bemishini yevidiyo abahamba phambili emhlabeni, isabelo sesibili ngobukhulu semakethe yezinhlelo zokuphepha zomhlaba wonke. Okwamanje i-Dahua isikhundla sesibili esilinganisweni sezinkampani ezinokuthengiswa okukhulu kwe-a&s Security 50.
Ukusebenzelana okuseduze kwezinkampani zethu kwenze kwaba nokwenzeka ukuqalisa ukuhlanganiswa kwezingxenyekazi zemishini eminingi, ingqikithi yezinkulungwane zamamodeli amakhamera enethiwekhi namarekhodi evidiyo.
Ngo-2017, senze isixazululo esikuvumela ukuthi uxhume amakhamera we-analog asezingeni eliphezulu nencazelo ephezulu efwini usebenzisa
Siphinde sakwazi ukuhlinzeka ngoomakhenikha abalula bokuxhuma noma iyiphi inombolo yamakhamera e-Dahua emafini, kungakhathaliseki ukuthi akuyiphi indawo, ngaphandle kokusebenzisa ama-DVR, ama-PC noma isofthiwe eyengeziwe.
Ngo-2019, saba ozakwethu ababalulekile ngaphakathi kwe-DIPP () - uhlelo lokubambisana kwezobuchwepheshe okuhloswe ngalo ukuthuthukiswa okuhlangene kwezixazululo eziyinkimbinkimbi ezihlanganisiwe, okuhlanganisa izixazululo zokuhlaziya amavidiyo. I-DIPP ihlinzeka ngomklamo obalulekile kanye nokwesekwa kwezobuchwepheshe kwemikhiqizo ehlanganyelwe.
Ukusekelwa kwe-Dahua kuzo zonke izigaba zokudala imikhiqizo emisha kusivumele ukuthi sihlanganyele nephrothokholi yomdabu ezixazululweni ezahlukene. Enye yamagajethi athakazelisa kakhulu onyakeni odlule , lapho sakwazi ukufeza ukuhambisana namakhamera we-Dahua ezingeni ledivayisi yabo "yomdabu".
Liholelaphi βibhulohoβ?
Ibhuloho igajethi elingana nerutha encane ye-Wi-Fi. Leli bhokisi likuvumela ukuthi uxhume amakhamera afika kwangu-16 anoma yiluphi uhlobo efwini le-Ivideon. Lokhu kusho ukuthi abasebenzisi bezinhlelo zendawo bathola ukufinyelela kusevisi yefu ngaphandle kokushintsha imishini efakiwe. Ungakwazi ngisho nokwengeza amakhamera e-analog efwini ngokusebenzisa isiqophi sevidiyo esixhunywe ku-Ivideon Bridge.
Izindleko zedivayisi namuhla zingama-ruble angu-6. Ngokwesilinganiso senani/lesiteshi, ibhuloho seliphenduke indlela enenzuzo kakhulu yokuxhuma efwini le-Ivideon: isiteshi esisodwa esineBridge elinesitoreji esikhokhelwayo esiyisisekelo sengobo yomlando esivela ku-Ivideon sizobiza ama-ruble angu-000. Ukuze uqhathanise: lapho uthenga ikhamera enokufinyelela efwini, izindleko zesiteshi esisodwa zizoba ngama-ruble angu-375.
I-Ivideon Bridge akuyona nje enye i-DVR, kodwa idivayisi ye-plug-and-play eyenza kube lula ukuphatha okukude ngefu.
Esinye sezici ezithakazelisayo "zebhuloho" ukwesekwa okugcwele kwephrothokholi yomdabu yaseDahua. Ngenxa yalokho, iBridge iye yanothiswa ngemisebenzi enomthelela oqondile ekusebenzeni kahle kwezinhlelo zokubhekwa kwevidiyo.
Izici zomdabu zaseBridge kanye nenkundla ehlukene
Ukuqoshwa kwedatha yendawo
Imodi yokusebenza ye-Edge Storage iyatholakala kuwo wonke amakhamera e-Dahua nama-DVR axhunywe ngeBridge kusetshenziswa iphrothokholi yomdabu. I-Edge ikuvumela ukuthi urekhode ividiyo ngqo kumemori khadi yakho yangaphakathi noma i-NAS. I-Edge Storage inikeza amathuluzi okurekhoda avumelana nezimo:
- ukonga izinsiza zenethiwekhi nezokugcina;
- ukusabalalisa okuphelele kokugcinwa kwedatha;
- ukwenza ngcono ukusetshenziswa komkhawulokudonsa;
- ukudala ikhophi eyisipele yengobo yomlando uma kwenzeka ukuxhumeka kuhluleka;
- ukonga kungobo yomlando yamafu: kwanele ukufaka uhlelo lwentela encane - ngokwesibonelo, izindleko eziphansi zonyaka zamakhamera ayi-8 efwini kuzoba ama-ruble ayi-1/ngenyanga noma ama-ruble ayi-600/ngonyaka.
Itholakala kuphela ngephrothokholi yomdabu, imodi ye-Edge iyisixazululo sokurekhoda esiyi-hybrid, ngakolunye uhlangothi, sinciphisa izingozi zebhizinisi ezihlobene nokulahlekelwa kokuxhumeka kungazelelwe, futhi ngakolunye uhlangothi, ikuvumela ukuthi wonge ezindlekweni eziphezulu zethrafikhi.
Isetha i-OSD nokukhanya kwangemuva
I-Ivideon Bridge inikeza ukufinyelela ekusetheni imbondela yombhalo ngokunganaki, idethi nesikhathi esithombeni (Esibonisini Sesikrini, i-OSD).
Njengoba uhudula, umbhalo kanye nedethi iphawula ukuthi "namathela" kugridi engabonakali. Le gridi ihlukile kukhamera ngayinye, futhi kuye ngokuthi ilebula itholakala kuphi esithombeni, indawo yangempela yombhalo oyimboziwe ingase ibalwe ngokuhlukile.
Uma uvala izimbondela zombhalo noma zedethi, izilungiselelo zazo ziyalondolozwa, futhi uma uzivula, ziyabuyiselwa.
Izilungiselelo ezitholakala kukhamera ethile zincike kumodeli yayo kanye nenguqulo ye-firmware.
Amapharamitha wokusebenza komtshina onyakazayo
Uhlelo lukuvumela ukuthi uguqule ngokuzwela amapharamitha wokusebenza komtshina onyakazayo, okuhlanganisa ukusetha indawo ehlonza ngokungafanele.
Ukushintsha amapharamitha wokusakaza ividiyo
Ukulungisa amapharamitha wevidiyo nomsindo wokusakaza kuzosiza ukunciphisa umthwalo esiteshini se-inthanethi - "ungasika" amanani amaningi futhi wonge kuthrafikhi.
Ukusethwa kwemakrofoni
Njengokusakazwa kwevidiyo, izilungiselelo zemakrofoni zinikeza ukufinyelela esikalini sokuzwela esikuvumela ukuthi ulungiselele ukusetshenziswa kwedivayisi ngaphakathi kwamagumbi anomsindo.
isiphetho
Ibhuloho iyithuluzi elisebenza emhlabeni wonke elinamandla okumisa ngobuchwepheshe ukuxhumana kwekhamera. Le modi izodingeka uma uhlela ukuxhuma irekhoda endala noma ikhamera efwini engakwazi ukutholwa ngokuzenzakalelayo.
Ngenxa yokuguquguquka kwezilungiselelo zeBhuloho, umsebenzisi angakwazi ukubhekana kalula nezimo lapho ikheli lasesizindeni se-inthanethi, ukungena ngemvume kwekhamera/iphasiwedi lishintsha, noma idivayisi ishintshwa. Ngokushintsha ikhamera, ngeke ulahlekelwe ingobo yomlando yamavidiyo arekhodiwe ngaphambilini efwini kanye nokubhalisa okukhokhelwe kakade kwesevisi.
Futhi nakuba iBridge ikuvumela ukuthi usebenze ne-ONVIF kanye ne-RTSP ezingeni lochwepheshe, ngaphandle kokukhathaza umsebenzisi ngezilungiselelo zezinga "lokuqala ku-Boeing cockpit", "ukubuya" okukhulu kakhulu okuvela kumakhamera kungazwakala ngokuhlanganisa okujulile, njengoba kungase kwenzeke. kubonakala esibonelweni sosekelo lwephrothokholi ye-Dahua Technology yomdabu.
