Izindawo zangaphandle zethula inselelo ehlukile ezinhlelweni zomsindo. Imvula, umoya, uthuli, nokushintshashintsha okukhulu kwezinga lokushisa kungonakalisa ngokushesha izipikha ezijwayelekile, kuyilapho izintambo zikagesi nezenethiwekhi zivame ukuba nzima ukuzifaka. I-OPA Co., Ltd. yakhe isixazululo esinqoba lezi zithiyo ngohlelo lwe-Network Horn Speaker, uchungechunge lwamadivayisi ane-IP65, anikwa amandla nge-PoE+, futhi ahambisana ne-ONVIF, aklanyelwe ngokuqondile ukusakaza umphakathi okuthembekile, ukuxhumana okuphuthumayo, nokumemezela kwezimboni. Lesi sihloko sihlola ngokujulile izipikha ze-horn zenethiwekhi ze-OPA, sichaza izinzuzo zazo zobuchwepheshe, amandla okuhlanganiswa, nezimo eziningi lapho ziletha khona umsindo ocacile noqondakalayo kungakhathaliseki izimo zezulu. Noma ngabe uthuthukisa uhlelo olukhona lokumemezela noma wakha ingqalasizinda entsha ehlakaniphile, ukuqonda amandla alezi zipikha ezingenamanzi kubalulekile ukuze wenze utshalomali olunolwazi.

Uchungechunge lwezipikha zekhwalithi yomsindo lwe-OPA's Network Horn Speaker lwakhiwe ngamamodeli amabili ayinhloko — i-OPA-HORN-100 ne-OPA-HORN-200 — ngalinye lakhelwe ukunikeza ukusakazwa komsindo okukhethekile nokuqina kwesikhathi eside ezindaweni ezinzima zangaphandle. Uchungechunge lwakhiwe ngomzimba oqinile, omelana nesimo sezulu ophethe isilinganiso se-IP65, okusho ukuthi uvikeleke ngokuphelele ekungeneni kothuli futhi umelana namanzi anomfutho ophansi avela noma iyiphi indlela. Lokhu kwenza izipikha zifaneleke ezindaweni ezisogwini, izimo zezulu ezinemvula, nezindawo zezimboni ezinothuli lapho izipikha zendabuko zingahluleka khona phakathi nezinyanga. Ngaphezu kwalokho, womabili amamodeli afaka i-amplifier ye-Class D eyakhelwe ngaphakathi, enikeza ukusebenza kahle okuphezulu nokukhiqiza ukushisa okuphansi, iqinisekisa ukusebenza komsindo okungaguquki ngisho nalapho isipikha sisebenza ngamandla aphezulu isikhathi eside. Uchungechunge lwakhelwe ukuhlanganiswa kwenethiwekhi okungenazinkinga, lusekela kokubili i-PoE+ (IEEE 802.3at) nokufakwa kwamandla kwe-DC, okwenza ukufakwa kube lula ngokuqeda isidingo sezintambo zamandla ezihlukile futhi kuvumele intambo eyodwa ye-Ethernet ukuthi ithwale kokubili idatha nogesi.

I-OPA-HORN-100 iyimodeli enezinga lokungena elingaphansi kweqoqo, inikela ngamandla alinganiselwe angu-100 watts ukuze ihlanganise indawo ebanzi ezindaweni ezingaphandle eziphakathi nendawo njengezindawo zokupaka, izindawo zezitshalo, nezimboni ezincane. Inezindonga ezingenamvula ze-IP65 kanye ne-amplifier yakhelwe ngaphakathi ye-Class D, futhi isekela i-PoE+ kanye ne-DC input ukuze kube nokukhetha okuguquguqukayo kokufakwa. Ngokuzilungiselela ngokuzenzakalelayo, i-OPA-HORN-100 ingalungiselelwa ngokuzenzakalelayo uma ixhunywe kunethiwekhi, inciphisa kakhulu isikhathi nomzamo odingekayo ukufaka inani elikhulu lamayunithi. I-OPA-HORN-200, ngakolunye uhlangothi, iqhubekisela phambili ukusebenza ngamandla angu-200 watts, iletha izinga eliphezulu lokucindezela komsindo (SPL) kanye nobubanzi befrikhwensi obuthuthukisiwe obubeka phambili ukucaca kwezwi ezimemezelweni ezibalulekile. Le modeli ihambisana ne-ONVIF 2.4, ivumela ukuhlanganiswa okuqondile nezinhlelo zokuphatha amavidiyo (VMS) nezinye izinkundla zokuphepha, futhi inikeza izinketho eziningi zokufaka okuhlanganisa izisekelo zensika, zodonga, nophahla ukuze kube nokuguquguquka okukhulu ekubekeni. Zombili lezi zinhlobo zisekelwa ukuzibophezela kwe-OPA kwekhwalithi futhi ziyatholakala ngamashidi emininingwane anemininingwane kuwebhusayithi yenkampani.Ikhaya ikhasi, lapho abathengi abangaba khona bengahlola khona uhla olugcwele lwezicaciso.

Okwehlukanisa izikhulumi zophiko lwenethiwekhi ze-OPA kunezikhulumi zophiko ezijwayelekile ze-analog amandla azo okusebenza njengamanodi enethiwekhi azimele ngaphakathi kohlelo olukhulu lwe-audio olususelwa ku-IP. Isikhulumi ngasinye sinekheli yaso ye-IP, okuvumela ukubhekana ngakunye, ukulawula okusekelwe ezindaweni, nokuphathwa kude ngesikhombi sewebhu noma isofthiwe yangaphandle. Lendlela egxile kunethiwekhi isho ukuthi ungahlela izimemezelo, usakaze imilayezo ebukhoma, noma uqalise izexwayiso ezirekhodiwe ngaphambilini ezindaweni eziningi ngasikhathi sinye ngaphandle kwezintambo eziyinkimbinkimbi ezenziwe ngokwezifiso. Ngaphezu kwalokho, uchungechunge lusekela iphrothokholi ye-SIP, okwenza luhambisane nezinhlelo ze-IP-PBX nezinhlelo zokusebenza ze-softphone, okuwubuhle obukhulu ezinhlanganweni ezivele zisebenzisa ucingo lwe-VoIP. I-amplifier eyakhelwe ngaphakathi enokucubungula kwezwi le-HD iqinisekisa ukuthi imilayezo ekhulunywayo ayigcini nje ngokuba nomsindo omkhulu kodwa futhi iyezwakala kahle, inqamula umsindo wangemuva ezindaweni ezinabantu abaningi. Lokhu kuhlanganiswa kwe-hardware eqinile nobuhlakani benethiwekhi yikho okwenza i-OPA ibe yigama elithenjwayo emkhakheni wezixazululo zokuxhumana nge-IP, njengoba kugqanyiswa kuwebhusayithi yenkampani.Mayelana Nathi ikhasi.

Uma utshala imali kwisipikha sekhodi yokuxhumana (network horn speaker), awuthengi nje isipikha — ukhetha ubuchwepheshe okumele busebenze ngokuthembekile iminyaka eminingi ezindaweni ezivelele. Uchungechunge lwe-OPA lunikezela lokhu kuthembeka ngeqoqo lezici ezibhekana nezinkinga ezivamile zokufakwa komsindo ngaphandle. Isilinganiso sokuvikelwa se-IP65 siwumugqa wokuqala wokuzivikela, siqinisekisa ukuthi izingxenye zangaphakathi zikagesi zihlala ziphephile emswakameni, othulini, ngisho nasekuhlanzeni ngamanzi anamandla. Leli zinga lokuvikelwa ekungeneni kwamanzi libalulekile ekufakweni eduze nolwandle, ezitshalweni zamakhemikhali, noma ezifundeni ezinemvula enkulu yezinkathi zonyaka, ngoba liqinisekisa ukusebenza okungaphazamiseki futhi lehlisa izindleko zokulungisa. Amandla e-Power-over-Ethernet (PoE+) nawo aguqulela izinto, ngoba avumela intambo eyodwa ejwayelekile ye-Ethernet ukuthi inikeze kokubili ukuxhumana kwenethiwekhi namandla kagesi ngasikhathi sinye. Lokhu kuqeda isidingo sezindawo zikagesi ze-AC ezihlukile eduze kwesipikha ngasinye, okuvame ukuba ngeke kwenzeke noma kube nezindleko eziphezulu ezindaweni zangaphandle, futhi kwenza inqubo yokufaka ibe esheshayo, ihlanzeke, futhi yonge imali.

Ukuthobela i-ONVIF kungenye into ephawulekayo, ngoba iqinisekisa ukuthi isipikha se-network horn singahlanganiswa ngqo ezinhlelweni zokuphepha zakudala nezanamuhla ngaphandle kokuboshwa ubunikazi. Lokhu kusho ukuthi ungakwazi ukuphatha izipikha zakho ngokusebenzisa isikhombimsebenzisi esifanayo esisetshenziselwa amakhamera akho e-IP nezinhlelo zokulawula ukufinyelela, kwenze imisebenzi ihambe kahle futhi kube lula ukuqeqesha abasebenzi bakho bezokuphepha. Ukusekelwa kwe-SIP protocol kuya phambili ngokwenza isipikha sihambisane ngokugcwele ne-IP-PBX yakho ekhona, ikunike amandla okwenza izimemezelo zekhasi kunoma iliphi ifoni yedeski noma i-softphone client kunethiwekhi yakho. Cabanga ngesimo lapho unogada ezoshaya inombolo yokwandisa ukuze amemezele isexwayiso esiphuthumayo kuso sonke isikhungo — lokho kuba umsebenzi olula, onokwethenjelwa ngesipikha se-OPA. Ngaphezu kwalokho, isici sokuxhuma kwe-peripheral sikuvumela ukuthi uxhumane amadivayisi angaphandle njengama-alarm, ama-motion sensor, noma amakhamera ngqo esipikheni, udale isiteshi sokuqwashisa esizimele esingaqala imilayezo ezenzakalelayo yezwi lapho kwenzeka umcimbi. Isibonelo, ikhamera enokutholwa kokunyakaza ingakhombisa isipikha ukuthi sidlale isexwayiso "sendaweni evinjelwe" ngaphandle kokungenelela komuntu.

Ukuhlinzwa okuzenzakalelayo kuyisici esivame ukunganakwa kodwa sibe sibaluleke kakhulu lapho kuthunyelwa izipikha eziningi ezindaweni eziningi. Ngezinhlelo zendabuko ze-analog, isipikha ngasinye kufanele sicushwe ngokukhethekile, okudinga umsebenzi omningi futhi kuvame ukuba namaphutha. Izipikha zophondo zokuxhumana ze-OPA zithola ngokuzenzakalelayo futhi zamukele izilungiselelo ezivela kuseva emaphakathi, zikuvumela ukuthi uthumele amashumi noma ngisho namakhulu amayunithi emahoreni ambalwa. Lokhu kuzuzisa kakhulu abathengisi abanamagatsha amaningi, iziphathimandla zomasipala, kanye namakhampasi ezimboni okudinga ukuthi benze ukwakheka kwabo kwepaging kube okujwayelekile. Ngaphezu kwalokho, i-amplifier ye-Class D eyakhelwe ngaphakathi yakhelwe ukusebenza kahle kakhulu, okungagcini nje ngokunciphisa ukusetshenziswa kwamandla kodwa futhi kunciphisa ukwakheka kokushisa ngaphakathi kwebhokisi elivaliwe. Lokhu kusebenza kahle kokushisa kunomthelela ekuphileni isikhathi eside kwesipikha, okwenza kube yisixazululo esidinga ukunakekelwa okuncane. Zonke lezi zici zihlangana ukudala umkhiqizo ongewona nje isipikha esikhulumayo kodwa okuyinkundla ebanzi yokuxhumana ngomsindo yangaphandle, ekwazi ukusekela konke kusukela ezimemezelweni ezijwayelekile kuya emiyalezweni yokuphepha kwempilo.

Ukuze kukusize ukhethe imodeli efanele izidingo zakho ezithile, ithebula elingezansi liqhathanisa imininingwane eyinhloko yobuchwepheshe ye-OPA-HORN-100 ne-OPA-HORN-200. Le mininingwane ithinta ngqo indawo okufinyelela kuyo isipikha, ikhwalithi yomsindo, nokuhambisana, ngakho kubalulekile ukuyibuyekeza ngokucophelela ngaphambi kokwenza isinqumo sokuthenga. Womabili amamodeli afana ngezinga le-IP65, i-amplifier yakhelwe ngaphakathi ye-Class D, namandla okufaka e-PoE+, kodwa ahlukile ngamandla okukhiphayo, ukusabela kwefrikhwensi, nokuthobela imithetho. Ithebula liklanyelwe ukukunikeza umbono ocacile, wokubheka eceleni kwalokho imodeli ngayinye ekulethayo, okukuvumela ukuthi ufane isipikha nezidingo zomsindo zendawo yakho. Ukuze uthole imininingwane yakamuva, hlala ubheka amashidi esemthethweni atholakala kuwebhusayithi ye-OPA noma uwacele eqenjini lethu lezokuthengisa.

Njengoba ithebula likhombisa, i-OPA-HORN-200 inikeza amandla okuphuma acishe aphindwe kabili kanye nobubanzi bemvamisa obubanzi, okuhumusha ekukhuphukeni kwe-SPL nokucaca kwezwi okungcono, okwenza kube ukukhethwa okuthandwayo ezinkundleni ezinkulu zomphakathi, izindawo zezimboni, noma noma yikuphi lapho umsindo wendawo ubalulekile khona. Iphethini yokusabalalisa emncane ye-OPA-HORN-200 ivumela ukuqondisa umsindo ngokunemba okwengeziwe, okusiza ekuphakamiseni amabanga amade emgwaqweni noma kumabhena. Ngokuphambene, i-OPA-HORN-100 inikeza iphethini yokusabalalisa ebanzi esebenza kahle ezindaweni ezivulekile lapho ufuna ukusabalalisa umsindo ngokulinganayo. Womabili amamodeli asekela i-PoE+ kanye ne-DC input, ngakho angaxhaswa ngogesi ngenethiwekhi noma ngomthombo wamandla wasendaweni, okunikeza abafaki ithuba lokukhetha indlela esebenziseka kakhulu endaweni ngayinye. Isimo sokugunyazwa sihlanganisa ukuthobela i-EN, i-FCC, ne-IP65 kubo bobabili, okuqinisekisa ukuthi bahlangabezana namazinga omhlaba wonke okuphepha nokuvikelwa kwemvelo. Lezi zicaciso ziqinisa ukufaneleka kwezipikha ezinhlelweni ezibalulekile lapho ukuma kungavumelekile khona.

Ukuhlanganiswa kuvame ukuba yinselele enkulu kunazo zonke ekwengezeni ubuchwepheshe obusha ohlelweni olukhona, futhi i-OPA iklame izipikha zayo zomsindo zenethiwekhi ukuze lenqubo ibe lula ngangokunokwenzeka. Ukuthobela i-ONVIF kwe-OPA-HORN-200, kanye nemojula ye-ONVIF engakhethwa ye-OPA-HORN-100, kuqinisekisa ukuthi isipikha siyakwazi ukuqashelwa nokulawulwa yizinkundla ezinkulu ze-VMS ezifana ne-Milestone, i-Genetec, ne-Nuuo ngaphandle kwesidingo sesofthiwe yobunikazi. Lokhu kuvumela abasebenzi bezokuphepha ukuthi bafake izaziso zomsindo ngqo emsebenzini wabo wokuqapha ngevidiyo, ngokwesibonelo, ngokuxhumanisa umcimbi wokunyakaza ekhamera nomlayezo wokuxwayisa oqoshiwe ngaphambilini odlalwa ngesipikha somsindo. Ukuhlanganiswa kuhamba nhlangothi zombili, okusho ukuthi ungasebenzisa isipikha njengethuluzi lokukhipha umsindo ekuxhumaneni ngezindlela ezimbili kwezinye izilungiselelo, okuvumela abasebenzi abakude ukuthi bakhulume ngqo nabahlaseli noma izivakashi zesakhiwo. Lokhu kuhambisana kahle nomkhuba okhulayo wezinkundla zokuphepha ezihlangene ezihlanganisa ividiyo, ukulawulwa kokufinyelela, nomsindo kusixhumi esisodwa sokuphatha.

Ukusekelwa kwephrothokholi ye-SIP kungenye yezici ezibalulekile zokuhlanganiswa, ngoba ivumela isipikha se-horn senethiwekhi ukuthi sibhalise kunoma iyiphi i-PBX ehambisana ne-SIP, okuhlanganisa i-Asterisk, i-3CX, ne-FreeSWITCH. Uma sesibhalisiwe, isipikha siba yisandiso ohlelweni lwakho lwefoni, ukuze ukwazi ukusishayela ukuze wenze izimemezelo noma usixhume eqenjini lokumemezela. Lokhu kusebenza kubaluleke kakhulu emahhovisi, ezikoleni, nasezibhedlela asevele esebenzisa i-VoIP telephony, ngoba kuqeda isidingo sohlelo oluhlukile lokumemezela futhi kunciphisa izindleko zengqalasizinda. Ukuhlanganiswa ne-SIP futhi kusekela ukumemezela kwe-multicast nezici ze-intercom, okukwenza ukwazi ukusakaza imilayezo kuzipikha eziningi ngasikhathi sinye noma ukuqalisa ingxoxo yephoyinti-kuya-ephoyinti phakathi kwesipikha nefoni. Ngaphezu kwalokho, inketho yokuxhumana kwe-peripheral ikuvumela ukuthi uxhumane amadivaysi angaphandle njengama-door contacts, ama-smoke detectors, noma izibani ze-strobe ku-auxiliary input yesipikha, ukuze umcimbi wehadiwe ukwazi ukuqalisa impendulo yomsindo ngokushesha. Isibonelo, i-smoke detector ingadlala ngokuzenzakalelayo umlayezo wokuphuma, noma i-parking gate sensor ingamemezela ukufika kwemoto.

I-OPA iyaqonda ukuthi konke ukufakwa kwezinto kuhlukile, yingakho inkampani inikeza imihlahlandlela ebanzi yokuhlanganisa kanye nosekelo lobuchwepheshe ukusiza ekucushweni. Lezi zinsiza zitholakala ekhasini le-Izindaba futhi ngokuxhumana ngqo nethimba lobunjiniyela le-OPA. Kumakhasimende adinga izici ezingokwezifiso noma izinguquko, i-OPA futhi inikeza i-Yenza Ngokwezifisoisevisi elivumela amakhasimende ebhizinisi ukuthi aguqule i-firmware yesipikha, umbala we-enclosure, noma i-mounting hardware ukuze kuhambisane nezidingo zephrojekthi yabo ethile. Leli zinga lokuguquguquka alivamisile embonini yomsindo futhi libonisa ukuzibophezela kwe-OPA ekubeni uzakwazi wesikhathi eside hhayi nje umthengisi womkhiqizo. Noma ngabe uhlanganisa nesistimu yakudala ye-analog nge-converter noma usabalalisa isixazululo esiphelele sedijithali, izipikha zomgwaqo ze-OPA zingalungiswa ukuze zihambisane, kuqinisekiswa ukuthi utshalomali lwakho luhlala lubalulekile njengoba ubuchwepheshe bakho buqhubeka nokuthuthuka.

Ukusebenza okuhlukahlukene kwezipikha zophiko lwenethiwekhi ze-OPA kuzenza zifanelekele izindawo eziningi zangaphandle nangaphakathi, noma kuphi lapho kudingeka khona umsindo ocacile nothembekile. Enye yezindlela ezivame kakhulu zokusetshenziswa isemapaki nasezindaweni zomphakathi, lapho iziphathimandla zedolobha zisebenzisa izipikha ukudlala umculo ohleliwe, izimemezelo zemicimbi, kanye nezexwayiso eziphuthumayo. Ngenxa yokuthi izipikha zivikelwe esimweni sezulu futhi zidinga kuphela intambo yethiwekhi eyodwa, zingafakwa kalula ezinsikeni zezibani, ezindaweni ezinophahla oluyisigubhu, noma ezingqalasizindeni ezikhona, kunciphisa umthelela obonakalayo kuyilapho kunikeza ukumboza okuhle kakhulu. Emapaki ezimoto nasezigcinweni zezimoto, izipikha zisebenza kokubili njengethuluzi lokusiza amakhasimende (isb., ukumemezela ngokushayela okuphephile noma usizo lokuthola imoto elahlekile) kanye nendlela yokuvikela ukweba noma ukucekelwa phansi kwempahla. Ikhono lokuhlanganiswa namakhamera okuphepha akhona nge-ONVIF lisho ukuthi uma ikhamera ithola ukuziphatha okusolisayo, isipika singakhipha isexwayiso esirekhodiwe ngaphambilini, okukhombisile ukuphumelela ekwehliseni izehlakalo.

Izikhungo zezimboni ezifana nezimboni zokukhiqiza, izindawo zokugcina impahla, nezindawo zokucubungula zizuzisa kakhulu kulezi zikhulumi ngoba zingakwazi ukudlulisa imiyalo ezwakalayo nama-alamu phezu komsindo wemishini. I-SPL ephezulu ye-OPA-HORN-200 isebenza kahle kakhulu ezindaweni lapho izimoto zokuthwala, ama-compressor, neminye imishini idala umsindo oqhubekayo wangemuva. Ezimweni eziphuthumayo, izikhulumi zingasakaza imiyalo yokuphuma ukuze kuqinisekiswe ukuthi bonke abasebenzi bathola umyalezo ngasikhathi sinye, okubalulekile ekuthobeleni izimiso zokuphepha. Izigxobo ezihlakaniphile, okuwumkhuba okhulayo ezingqalasizinda zezindawo ezihlakaniphile, zivame ukufaka izikhulumi zenethiwekhi zomsindo njengengxenye yohlelo lwazo oluhlanganisiwe. Lezi zigxobo zihlanganisa izibani ze-LED, amakhamera okuphepha, izinzwa zemvelo, nomsindo esakhiweni esisodwa, futhi izikhulumi ze-OPA zihlangana kahle kakhulu nalesi simiso ngenxa yobukhulu bazo obuncane, amandla e-PoE+, nokuxhumana kwenethiwekhi. Lokhu kuhlanganiswa kwenza amanethiwekhi ezigxobo ezihlakaniphile akwazi ukuhlinzeka ngolwazi lwezivakashi ngezilimi eziningi, izaziso zomgwaqo, nezimemezelo eziphuthumayo kuyilapho kugcinwa umgwaqo ohlanzekile, ongenazinkinga.

Iziteshi zikaphethiloli ngezinye izindawo ezifaneleka kahle, lapho ukwethembeka nokuphepha kubaluleke kakhulu. Isipikha se-network horn singasetshenziselwa uku-oda ngokudlula, izikhumbuzo zokuphepha, kanye nezimemezelo zamanani, konke kuvikelwe ngokwanele emhwamweni kaphethiloli nokuchayeka esimweni sezulu. Izinga le-IP65 liqinisekisa ukuthi isipikha singamelana namakhemikhali okuhlanza nokugezwa ngamanzi anomfutho ophezulu, okuyizindlela ezijwayelekile zokunakekela eziteshini zikaphethiloli. Izinhlelo zezaziso eziphuthumayo zomasipala noma izizikili zamasosha zincike kulezi zipikha ukuletha izexwayiso ezibalulekile ezixukwini ezikhulu zabantu, ngokuvamile zisebenzisa inethiwekhi yamayunithi asatshalaliswa endaweni ebanzi. Isici soku-oda ngokuzenzakalelayo senza kube nokwenzeka ukusebenzisa amakhulu ezipikha ngokushesha, futhi umthetho we-SIP uvumela uhlelo ukuthi lilawulwe ezikhungweni eziphuthumayo ezimaphakathi. Kuzo zonke lezi zindawo, izipikha ze-network horn ze-OPA zinikeza ukwethembeka okudingwa ukuxhumana okubalulekile, kuqinisekisa ukuthi umlayezo wakho uyezwa njalo, ngomsindo ophezulu nokucacile.

I-OPA Co., Ltd., eyaziwa ngokuthi i-Guangzhou Oudim Electroacoustic Technology Co., Ltd., isungule ukuzinza kwayo njengomholi wezinto ezintsha ezixazululweni zomsindo ezisekelwe ku-IP.

Emaphrojekthini amakhulu, i-OPA inikeza usizo lobunjiniyela olugxile emaphrojekthini athile, okuhlanganisa imidwebo ye-3D, ukulingiswa kwe-acoustic, kanye nokusekelwa kokumiswa endaweni. Leli modeli lobambiswano lizuze i-OPA idumela lokuthembeka, yingakho imikhiqizo yayo isetshenziswa emaphrojekthini amadolobha ahlakaniphile, izikhungo zezokuthutha, kanye nezimboni eziyinkimbinkimbi emhlabeni wonke. Uma ukhetha i-OPA, awuthengi nje isipikha; utshala imali ebudlelwaneni besikhathi eside neqembu elikhathalela impumelelo yephrojekthi yakho. Ukuze ubone ububanzi obugcwele bemikhiqizo ye-OPA, okuhlanganisa izinhlelo ze-intercom ezixhumene nenethiwekhi kanye neminye imishini ye-acoustic, ungabuka inkampani.Imikhiqizo ikhasi, eliqokomisa ububanzi bezixazululo zabo zokuxhumana nge-IP. Ngaphezu kwalokho, iwebhusayithi yenkampani kanye ne-Izindaba isigaba sinikeza izibuyekezo ezijwayelekile ngobuchwepheshe obusha nokuqonda kwemboni, kuqinisekisa ukuthi uhlala uphambili ekuhlanganisweni komsindo.

Amakhono okwenza ngendlela oyifisayo e-OPA angenye inzuzo ebalulekile, ikakhulukazi kumakhasimende anezidingo ezihlukile zophawu noma zokusebenza. I-amplifier eyakhelwe ngaphakathi nemojula yenethiwekhi zihlala ekwakhiweni okuyimojula okungashintshwa ukuze kufanele izimo ezahlukene zebhokisi, imibala, noma izinsiza zokufaka. Isibonelo, umasipala angacela ibhokisi eliluhlaza elihambisana nendawo yepaki, noma inkampani kaphethiloli ingafaka uphawu olwenziwe ngokwezifiso ku-horn. I-Yenza Ngendlela Oyifisayoisevisi liphethe yonke lemininingwane, kusukela emcabangweni wokuqala kuya ekukhiqizweni, ngaphandle kokudela ukusebenza noma ukwethembeka. Lokhu kuguquguquka kwenza i-OPA ibe umlingani okhangayo kubahlanganisi bezinhlelo nabasebenzisi bokugcina abadinga isixazululo esihambisana nokucaciswa kwabo ngqo. Ngaphezu kwalokho, inethiwekhi yokusabalalisa yomhlaba wonke ye-OPA iqinisekisa ukulethwa ngesikhathi nokusekelwa kwezobuchwepheshe endaweni, kunciphisa izingozi ezihambisana nokuthengwa kwamazwe ngamazwe. Embonini lapho ubukhulu obufanayo kubo bonke ngokuvamile buholela ekuyekeleni, ukuzimisela kwe-OPA ukwenza izixazululo ngendlela ethile kuyinzuzo yokuncintisana ehlukile.

Isipikha esinezwi lenethiwekhi isipikha esixhuma kunethiwekhi ye-IP, sithola amandla kanye nedatha yomsindo ngocingo olulodwa lwe-Ethernet, ngokuvamile sisebenzisa i-PoE noma i-PoE+ technology. Ngokungafani nesipikha esijwayelekile se-analog horn, esidinga i-amplifier ehlukile kanye nezintambo ze-analog zomsindo, isipikha se-network horn sinayo i-digital amplifier eyakhelwe ngaphakathi kanye ne-network interface, esivumela ukuthi sibhekwane ngaso ngasinye, silawulwe kude, futhi sihlanganiswe namanye amadivayisi enethiwekhi. Lokhu kwenza kube lula ukufaka futhi kunika amandla izici ezithuthukile ezifana nokuhlela, ukumemezela ngezindawo, kanye nokuhlanganiswa kwe-SIP telephony, okwenza kube yisixazululo esiguquguqukayo nokuhlakaniphile kakhulu ezinhlelweni zokukhulumela zomphakathi ezingaphandle.

Ilingi le-IP65 likhombisa ukuthi isipikha sivikelwe ngokugcwele ekungeneni kothuli kanye nasekujikijelweni kwamanzi anomfutho ophansi kusukela kuzo zonke izinhlangothi. Lokhu kubalulekile ekufakweni kwangaphandle ngoba kuqinisekisa ukuthi imvula, uthuli oluqhutshwa umoya, kanye nokuhlanza ngqo ngepayipi lamanzi ngeke kulimaze izinto zikagesi zangaphakathi. Ngaphandle kwezinga le-IP65, isipikha singahluleka ngaphambi kwesikhathi ngenxa yokungena komswakama noma ukunqwabelana kwezinhlayiya, okuholela ekulungisweni njalo nokuphazamiseka enkonzweni. Izipikha zekhala zenethiwekhi ze-OPA ziklanywe ngezivalo ze-IP65, ziqinisekisa ukusebenza okuthembekile ezindaweni ezinzima iminyaka eminingi.

Izinkhulumo zophiko lwe-OPA zisekela kokubili i-PoE+ (IEEE 802.3at) kanye ne-DC 24V input, ngakho zingaxhunywa kuphela nge-PoE+ switch noma i-injector, kungadingeki ukuthi kube nesekethe kagesi ehlukile. Lokhu kulungele kakhulu ezindaweni lapho ukufaka i-AC wiring kungenzeki noma kubiza kakhulu. Kodwa-ke, uma uthanda ukusebenzisa umthombo wamandla wendawo, i-DC input inikeza enye indlela, ikunikeza ukuguquguquka okuphelele ngesikhathi sokufaka. Kubalulekile ukuqinisekisa ukuthi i-PoE+ switch yakho inikeza isabelo samandla esanele kuzo zonke izinkhulumo ezixhunyiwe, ikakhulukazi uma ufaka amayunithi amaningi.

ONVIF iyindinganiso yomhlaba wonke evumela amadivaysi okuphepha avela kubakhiqizi abahlukene ukuthi asebenzisane. Isipikha sekhala lenethiwekhi esihambisana ne-ONVIF singahlanganiswa kalula ezinhlelweni zokuphatha amavidiyo (VMS) kanye nezinye izinkundla zokuphepha, okusho ukuthi ungakwazi ukulawula izexwayiso zomsindo kusuka kusixhumi esifanayo namakhamera akho nokulawulwa kokufinyelela. Lokhu kunciphisa ubunkimbinkimbi, kugwema ukuvaleka komkhiqizi, futhi kukuvumela ukuthi udale izimpendulo ezizenzakalelayo ezinamandla, njengokucupha isexwayiso sezwi lapho ikhamera ithola ukunyakaza endaweni evinjelwe. I-OPA-HORN-200 ihambisana ne-ONVIF 2.4, kuyilapho i-OPA-HORN-100 ingafakwa imojuli ye-ONVIF engakhethwa.

I-SIP (Session Initiation Protocol) iyindinganiso yocingo lwe-VoIP, futhi ukusekelwa kwayo esipikheni se-network horn kuvumela isipika ukuthi sibhalise kusistimu yakho ekhona ye-IP-PBX. Lokhu kukuvumela ukuthi ushayele inombolo yangaphakathi yesipika ukuze wenze isimemezelo esibukhoma, noma ukulungisele ukuthi samukele amakhasi e-multicast. Nge-SIP, isipika siba inombolo yangaphakathi kunethiwekhi yakho yocingo, kususa isidingo sohlelo oluhlukile lwe-intercom noma lokumemezela. Lokhu kuwusizo ikakhulukazi emahhovisi, ezikoleni, nasezimbonini esezivele zithembele kwi-IP telephony ekuxhumaneni kwansuku zonke.

Yebo, izipikha zomsakazo ze-OPA zinezimbobo zokuxhuma ezingaphandle ezikuvumela ukuthi uxhumane imishini yangaphandle efana nezinzwa ze-alamu, izibani ezikhanyayo, noma okuthintwayo kweminyango ngqo esipikheni. Lokhu kukuvumela ukuthi udale amasistimu okuqwashisa azimele lapho okokufaka kwehardware kuvula umlayezo womsakazo orekhodiwe ngokushesha. Isibonelo, inkinobho yokwethuka noma insiza yokuthola intuthu ingavula isimemezelo sokuphuma ngaphandle kwesidingo sephaneli yokulawula ehlukile. Lokhu kuguquguquka kwenza isipika sibe yisakhiwo esiguquguqukayo sezixazululo zokuphepha nezokuvikela ezenziwe ngokwezidingo.

I-OPA-HORN-100 iyisipikha esingama-watts angu-100 esinendawo ebanzi yokufinyelela, ekahle ezindaweni zangaphandle eziphakathi nendawo njengezindawo zokupaka nezindawo ezincane zezimboni. I-OPA-HORN-200 iphindaphinda umphumela ibe ngama-watts angu-200, inikeza i-SPL ephezulu kanye nendlela eqondile yokufinyelela, efanele izindawo ezinkulu nezindawo ezinomsindo. I-OPA-HORN-200 futhi ihlanganisa ukuthobela i-ONVIF 2.4 kanye nobubanzi bemvamisa ebanzi, okwenza kube ukukhetha okuphezulu ezinhlelweni ezidinga ukuqondakala okuphezulu nokuhlanganiswa.

Cha nhlobo. Izipikha zophiko lwenethiwekhi ze-OPA zisekela ukuzilungiselela ngokuzenzakalelayo, okusho ukuthi zingathola ukucushwa kwazo kanye nezibuyekezo ze-firmware ngokuzenzakalelayo kusuka kuseva yokuphatha emaphakathi lapho ziqala ukuxhunywa kunethiwekhi. Lokhu kuqeda isidingo sokucushwa ngesandla kweyunithi ngayinye, kunciphisa isikhathi sokusetshenziswa kusuka ezinsukwini kuya emahoreni, ngisho nakumaphrojekthi anamakhulu ezipikha. Ngaphezu kwalokho, ukuxhumeka kwe-PoE+ kwenza ukufakwa ngokomzimba kube lula ngoba udinga nje ukugijimisa intambo eyodwa ye-Ethernet kusipikha ngasinye.

Yebo, nakuba isipikha sekholomu senethiwekhi siklanyelwe ukusetshenziswa ngaphandle, izinga laso le-IP65 nokwakheka kwalo okuqinile kusenza sifanelekele nasezindaweni zangaphakathi ezinzima njengamakamelo emishini, amaworkshops, amahholo ezemidlalo, kanye nezindlela ezimboziwe lapho kungaba khona umswakama noma uthuli. I-SPL ephezulu yesipikha kanye nokukhipha umsindo oqondiswayo nakho kuyasiza ezindaweni zangaphakathi ezinkulu ezinomsindo omkhulu. Uma udinga isipikha sangaphakathi kuphela, i-OPA nayo inikeza ezinye izixazululo zomsindo zenethiwekhi ezingatholakala ekhasini labo lomkhiqizo.

Ukuze uthole isilinganiso esinemininingwane noma uhlele umbukiso obukhoma, ungavakashela iwebhusayithi ye-OPA bese ugcwalisa ifomu lokuxhumana, noma uthintane ngqo ngocingo noma nge-imeyili. Ithimba lokuthengisa lenkampani lizosebenza nawe ukuze liqonde izidingo zephrojekthi yakho, lincome imodeli efanele, futhi linikeze isilinganiso esenziwe ngokwezifiso. Kumaphrojekthi aphuthumayo, i-OPA iphinde inikeze ukusekelwa kobunjiniyela okusheshisiwe ukuze kusize ukuqedela ukwakheka kohlelo lwakho ngokushesha.
