Koj Puas Paub Txog Paj Ntaub Ntau npaum li cas?
Cov neeg xav tau nce rau cov ntaub ntawv ntau ntxiv thiab cov ntaub ntawv nrawm dua txhawb txoj kev loj hlob ntawm kev sib txuas lus thev naus laus zis. Qhov loj me ntawm cov ntaub ntawv chaw ua loj dua thiab cabling system ua cov nyom ntau dua. Tsis ntev los no, kev xa xov nkag mus rau hauv tsev hauv tsev thiab cov cuab yeej technology tshiab tau pib ua cov ntsiab lus tseem ceeb - PoE (Fais fab hla Ethernet). Koj paub ntau npaum li cas txog nws? Koj puas siv PoE li? Kab lus no yuav hais txog tej yam uas muaj feem rau PoE.
Tshuab PoE tso cai rau cov hloov hluav taws xob xa mus rau lub zog thiab cov ntaub ntawv los ntawm Ethernet cable tib lub sijhawm. Piv txwv koob yees duab digital ruaj ntseg. Lub koob yees duab kev ruaj ntseg digital ib txwm xav tau ob qho kev sib txuas thaum nws raug teeb tsa: kev sib txuas network thiab txuas fais fab. Cov qub ua rau lub koob yees duab sib txuas lus nrog cov kaw suab video thiab cov khoom ua kom pom, thaum tom kawg ib tus muab hluav taws xob rau lub koob yees duab. Txawm li cas los xij, yog tias lub koob yees duab yog POE-qhib, tsuas yog cov kev sib txuas hauv network yuav tsum tau ua, vim nws yuav tau txais nws lub zog hluav taws xob los ntawm qhov cable no thiab. Qee cov khoom siv hauv network hauv tsev feem ntau siv PoE, xws li VoIP xov tooj, IP lub koob yees duab thiab wireless nkag mus.
Yog tias koj siv PoE li, koj yuav tsum tau pom tias muaj PoE + cov khoom lag luam hauv khw. Dab tsi yog qhov txawv ntawm lawv? Cov cuab yeej siv hluav taws xob siv hluav taws xob raws li tus qauv PoE ib txwm, IEEE 802.3af, uas muab txog 15.4W ntawm DC zog rau txhua lub cuab yeej. Thaum PoE +, tseem hu ua PoE chav kawm 4, yog tus qauv tshiab, IEEE 802.3at, uas muab kom txog 30W ntawm lub zog rau txhua lub cuab yeej. Qhov ntawd yog qhov yuav hais tau rau PoE + tuaj yeem muab yuav luag ob zaug ntau npaum li lub zog los ntawm PoE dhau ntawm ib tus Ethernet cable. High-powered IP li xws li PTZ koob yees duab siv PoE +. Ib qho ntxiv, NVRs sib xyaw siv PoE + chaw nres nkoj los muab lub hwj chim thiab PTZ cov lus txib rau lub koob yees duab, nrog rau kev txuas video rau NVR.
PoE hloov yog lub tes hloov qhov network uas muaj Lub Hwj Chim dhau Ethernet txhaj tshuaj tsim. Nws ncaj qha mus ntxiv PoE rau koj lub network. Cias txuas lwm cov khoom sib txuas hauv lub network mus rau PoE hloov li qub, thiab tus tes hloov yuav pom tias lawv puas POE-tau zoo thiab ua kom muaj lub zog txuas. Cov chaw hloov pauv rau PoE muaj rau kom haum rau txhua daim ntawv thov, los ntawm tus nqi qis uas tsis siv neeg ua haujlwm hloov pauv nrog ob peb qhov chaw nres nkoj, mus txog rau cov chaw nres nkoj ntau txoj kab sib dhos ua ke nrog cov kev tswj tau zoo.
PoE thev naus laus zis coj ntau yam zoo rau kev xa xov network hauv tsev:
Lub sijhawm thiab Nyiaj Txiag: Ib zaug Ethernet cable tuaj yeem txhawb nqa ob qho tib si cov ntaub ntawv thiab lub zog xa. Dhau li, khiav Ethernet cable tsis xav tau hluav taws xob tsim nyog, nws tuaj yeem tsim los ntawm koj tus kheej.
Yooj Yim: Tsis tas yuav khi rau lub qhov hluav taws xob ruaj ruaj, muaj ntau qhov kev tso chaw rau cov khoom siv xws li IP koob yees duab thiab chaw nkag tau wireless, thiab lawv tuaj yeem hloov kho tau yooj yim yog tias xav tau.
Kev Nyab Xeeb: PoE tus me nyuam yog qhov ntse, thiab tsim los tiv thaiv cov khoom network dhau los ntawm kev siv ntau dhau, ua tsis tiav, lossis teeb tsa tsis raug.
Kev ntseeg tau: PoE zog los ntawm qhov chaw nruab nrab thiab ntau dua ntawm cov khoom siv, ntau dua li cov khoom sib txuas ntawm cov khoom faib ntsa. Nws tuaj yeem thim rov qab los ntawm kev siv hluav taws xob uas tsis muaj kev cuam tshuam, lossis tswj tau yooj yim lov lossis rov teeb khoom.
Scalability: Muaj lub zog nyob rau hauv lub network txhais tau tias kev teeb tsa thiab kev faib tawm ntawm cov kev sib txuas network yog yooj yim thiab siv tau.
PoE thev naus laus zis pom tseeb lub zog thiab cov ntaub ntawv xa hluav taws xob ntau ntawm tib Ethernet cable rau tib lub sijhawm, uas ua rau kev xa xov network hauv tsev yooj yim dua. FOCC muab cov khoom lag luam zoo PoE hloov pauv thiab txhua tus tuaj nrog lees lav ib xyoos, nrog rau cov teeb meem tsis zoo thaum lub sijhawm tswj hwm dawb.
