Hauv IP lub koob yees duab system thiab 100Mbps network cabling system, peb feem ntau siv Cat5e network cable rau teeb liab kis tau tus mob thiab lub hwj chim mov.Elzoneta yuav piav qhia qee qhov kev paub yooj yim rau koj raws li hauv qab no:
Yuav siv PoE fais fab mov li cas?
Rau kev siv hluav taws xob, peb yuav tsum muaj lub tswv yim ntawm PoE ua ntej.PoE (Power dua Ethernet), txhais tau hais tias lub zog hluav taws xob tawm los ntawm PoE hloov mus rau IP-raws li cov davhlau ya nyob twg (xws li IP xov tooj, wlan nkag point thiab IP koob yees duab) los ntawm Cat5e network cable.Tau kawg, ob qho tib si hloov thiab IP-based terminals muaj built-in PoE module;Yog tias IP-based terminals tsis muaj PoE module, nws yuav tsum siv Standard PoE splitter.
Nquag, peb xaiv siv tus txheej txheem thoob ntiaj teb PoE hloov, uas txhawb nqa 48V-52V, ua raws IEEE802.3af/802.3at.Vim tias qhov hloov pauv PoE no muaj PoE ntse ntes ua haujlwm.Yog tias peb siv tsis yog tus qauv PoE hloov, 12V lossis 24V, tsis muaj PoE ntse ntes muaj nuj nqi, thaum tso zis hluav taws xob rau IP-raws li cov terminals ncaj qha txawm tias lawv tau tsim-hauv PoE module lossis tsis, nws yooj yim rau hlawv IP-raws li cov chaw nres nkoj. , txawm ua puas lawv lub zog module.
Lub teeb liab kis tau deb npaum li cas?
Qhov kev ncua deb ntawm lub network cable yog nyob ntawm cov ntaub ntawv ntawm cable.Nquag, nws yuav tsum tau siv cov tooj liab tsis muaj oxygen, vim tias qhov tsis muaj oxygen tsis muaj tooj liab tsis kam yog me dua, nyob rau hauv 30 ohms rau 300 meters, thiab cov tub ntxhais tooj liab loj feem ntau yog 0.45-0.51mm.Nyob rau hauv ib lo lus, qhov loj ntawm cov tub ntxhais tooj liab loj, qhov me dua qhov kev tiv thaiv, qhov txuas ntxiv ntawm qhov kev ncua deb yog.
Raws li tus qauv Ethernet, qhov max teeb liab kis tau tus mob los ntawm PoE hloov yog 100 meters, uas txhais tau tias POE hloov siv thoob ntiaj teb tus qauv network cables rau lub hwj chim mov yog txwv nyob rau hauv 100 meters ib yam nkaus thiab.Ntau tshaj 100 meters, cov ntaub ntawv tuaj yeem ncua sijhawm thiab poob.Txhawm rau kom ntseeg tau qhov zoo ntawm qhov project, peb feem ntau siv 80-90 meters rau cabling.
Qee qhov kev ua tau zoo POE hloov pauv tau thov kom muaj peev xwm xa cov teeb liab mus txog 250 meters hauv 100Mbps network, puas yog?
Yog lawm, tab sis lub teeb liab kis tau tus mob yog txo los ntawm 100Mbps mus rau 10Mbps (bandwidth), thiab tom qab ntawd lub teeb liab kis tau tus mob yuav ncua mus rau Max 250 meters (cable nrog oxygen-dawb tooj liab core).Cov tshuab no tsis tuaj yeem muab cov bandwidth siab;Ntawm qhov tsis sib xws, qhov bandwidth yog compressed los ntawm 100Mbps mus rau 10Mbps, thiab uas tsis zoo rau kev sib kis tau zoo ntawm kev saib xyuas cov duab.10Mbps txhais tau tias tsuas yog 2 lossis 3 daim ntawm 4MP IP koob yees duab tuaj yeem nkag mus rau Cat5e cable, txhua 4MP IP lub koob yees duab bandwidth yog Max 2-3Mbps hauv Dynamic scene.Nyob rau hauv ib lo lus, Cat5e network cable tsis ntau tshaj 100 meters nyob rau hauv cabling.
ELZONETA Cat5e network cable siv lub siab ntshiab oxygen-dawb tub ntxhais nrog 0.47mm tooj liab core txoj kab uas hla, kom phim PoE IP lub koob yees duab thiab high-zoo qauv PoE hloov.Xws li qhov no ua kom cov teeb liab kis tau tus mob thiab cov khoom siv hluav taws xob ruaj khov rau tag nrho CCTV kev soj ntsuam.
