I-Intercom yevidiyo yekhebula lenethiwekhi
Uhlelo lwe-CASHLY Network Cable Video Intercom:
* Ikhebula elilodwa kuphela le-CAT-5E UTP eliya egumbini * Isifundi sekhadi le-ID/IC
* Isiteshi segumbi sixhumene ngesandla
* Engeza umsebenzi wokugcina isithombe seziteshi zegumbi lombala
* Ikhebula elilodwa le-CAT-5E STP kuphela elidingekayo ukuze kube nokuxhumeka kwenethiwekhi okuzinzile nokuthembekile
* I-Fiber optic iyahambisana nokuxhumeka kwenethiwekhi okude okufika ku-50km
* Ikhiphedi yesiteshi somnyango enokukhanya okusetshenziswa ebusuku * Hlangana nanoma yisiphi isakhiwo sephansi
Uhlelo lwe-analog villa intercom luhlelo lwe-intercom olusekelwe ekudlulisweni kwezintambo ezine. Luqukethe isiteshi sangaphandle se-villa kanye ne-monitor yangaphakathi. Lusekela i-visual intercom, ukubhekwa kwevidiyo, ukulawula ukufinyelela kanye neminye imisebenzi, futhi lunikeza isisombululo esiphelele sesistimu ye-video intercom esekelwe kuma-villa omndeni owodwa.

I-topology yenethiwekhi evame ukusetshenziswa ekuqedeni isakhiwo sebhasi, ayisekeli inethiwekhi eyindilinga noma efana nenkanyezi. Yonke i-node ixhunywe nge-serial ngebhasi elilodwa kuyisinqumo esihle, esithombeni esingenhla, i-topology yenethiwekhi ejwayelekile yesistimu ye-A8-05B ibonisiwe. Ama-node e-N axhunywe kunethiwekhi enamaphuzu amaningi. Ukuze uthole isivinini esiphezulu kanye nemigqa emide, ukumelana kokuphela kuyadingeka kuzo zombili izinhlangothi zomugqa ukuze kuqedwe ukubonakaliswa. Sebenzisa ama-resistor angu-100 Ω kuzo zombili izinhlangothi (kudingeka kuphela uma ubude bentambo bungaphezu kuka-2km). Inethiwekhi kumele yakhelwe njengomugqa owodwa onezinhlayiya eziningi, hhayi njengenkanyezi. Nakuba ubude bekhebula eliphelele bungaba bufushane ekucushweni kwenkanyezi, ukuqeda okwanele akusenakwenzeka futhi ikhwalithi yesignali ingase yehle kakhulu. KuMdwebo 1 obonise okulandelayo, u-b, d, f ukuxhumana okulungile kanye no-a, c, e ukuxhumana okungalungile.
Umdwebo 1
Uma usebenzisa intambo yenethiwekhi yesivikelo (STP), kufanele ugcine ukuqhubeka kwengqimba yokuvikela ibushelelezi, bese uxhuma uMhlaba endaweni eyodwa, njengoba kuboniswe kumdwebo.
Kudingeka ucingo
Isistimu isebenzise ikhebula le-CAT-5E UTP kanye ne-STP.
Ungayikhetha kanjani ikhebula le-CAT-5E elifanelekile?
Ukumelana kwentambo ngayinye kumele kube ngu-≤35Ω uma ubude bungu-305M (ubude be-FCL).
Isiteshi somnyango esiya ku-Power Supply sisebenzise i-RVV4*0.5, ukukhiya i-RVV2*0.5 esetshenzisiwe.
Isexwayiso:
Isithombe sesiteshi somnyango ngeke siboniswe ngokugcwele esikrinini sesiteshi se-Visual Room uma isiteshi segumbi sihluke kakhulu kugesi wevidiyo, ezindaweni ezifanele ebhasini lesakhiwo ukwandisa ugesi kungaxazulula le nkinga. Ugesi wevidiyo ojwayelekile ovela esiteshini se-Visual Room sebanga eliphezulu awukwazanga ukudlula amamitha angu-30.

Ngenxa yokuthi indinganiso ye-RJ-45 yenzelwe ukusetshenziswa ngaphakathi endlini kuphela, ayibi nomswakama futhi kulula kakhulu ukuyingcolisa noma ukuyingcolisa. Uma i-RJ-45 Head iphukile, kukhona ochwepheshe abanamathuluzi ochwepheshe adingekayo ukulungisa iphutha, lokhu kuzoholela ezindlekweni eziphezulu zokulungisa.
IScotchlok yilokho kanye esikudingayo. Eminyakeni engaphezu kwengu-45 eyedlule, i-3M yethule isixhumi sokuqala sokushintshashintsha kokushisa embonini - iScotchlok Connector UR. Namuhla, njengoba kunesidingo esikhulu samanethiwekhi asheshayo kanye ne-bandwidth ephezulu, uchungechunge oluphelele lwezixhumi namathuluzi e-3M luphinde lwavela. Sicela uvakashele ku-www.3M.com ukuthola ulwazi olwengeziwe lweScotchlok.
Ukubuka Konke Kwesistimu
Izici Zesixazululo
Umsebenzi we-Visual Intercom
Umsebenzisi angashayela ngqo i-indoor monitor efonini yomnyango ukuze athole umsebenzi we-visual intercom kanye nokuvula. Umsebenzisi angasebenzisa futhi i-indoor monitor ukufonela ezinye iziqaphi zangaphakathi ukuze athole umsebenzi we-indoor intercom.
Umsebenzi Wokulawula Ukufinyelela
Umsebenzisi angashayela i-indoor monitor esuka esiteshini sangaphandle emnyango ukuze avule umnyango nge-visual intercom, noma asebenzise ikhadi le-IC kanye nephasiwedi ukuvula umnyango. Umsebenzisi angabhalisa noma akhansele ikhadi le-IC bese esetha iphasiwedi esiteshini sangaphandle.
Umsebenzi we-Alamu Yokuphepha
Umsebenzisi angasebenzisa i-monitor yangaphakathi ukubuka ividiyo yesiteshi sangaphandle emnyango, futhi abuke ividiyo yekhamera ye-analog efakwe ekhaya.
