Umuyoboro wa Cat5e: Nigute wakoresha amashanyarazi ya PoE?Ihererekanyabubasha rigeze he?

Muri sisitemu ya kamera ya IP na sisitemu ya cabling ya 100Mbps often dukoresha umugozi wa Cat5e umuyoboro mugutanga ibimenyetso no gutanga amashanyarazi.Elzoneta azagusobanurira ubumenyi bwibanze kuri wewe nkuko bikurikira:

Nigute wakoresha amashanyarazi ya PoE?

Kumashanyarazi, dukwiye kugira igitekerezo cya PoE mbere.PoE (Imbaraga hejuru ya Ethernet), bivuze ko ingufu z'amashanyarazi ziva muri PoE zihinduranya kuri IP ishingiye kuri IP (nka terefone ya IP, aho wlan igera na IP kamera) binyuze mumurongo wa Cat5e.Birumvikana, byombi guhinduranya hamwe na IP ishingiye kubintu byubatswe muri PoE module;Niba IP ishingiye kuri IP idafite module ya PoE, igomba gukoresha ibice bisanzwe bya PoE.

Mubisanzwe, duhitamo gukoresha amahame mpuzamahanga ya PoE ahindura, ashyigikira 48V-52V, akurikira IEEE802.3af / 802.3at.Kuberako iyi PoE ihindura ifite imikorere ya PoE yubwenge.Niba dukoresha uburyo budasanzwe bwa PoE, 12V cyangwa 24V, nta mikorere yubwenge ya PoE ifite ubwenge, mugihe dusohora ingufu z'amashanyarazi kuri terefone ishingiye kuri IP tutitaye ko zubatswe muri module ya PoE cyangwa ntayo, biroroshye gutwika ibyambu bya IP bishingiye kuri IP. , ndetse byangiza imbaraga zabo module.

Ihererekanyabubasha rigeze he?

Intera yohereza imiyoboro ya kabili biterwa nibikoresho bya kabili.Mubisanzwe, igomba gukoresha umuringa utagira ogisijeni, kubera ko umuringa utarimo ogisijeni urwanya ntoya, muri 30 oms kuri metero 300, nubunini bwumuringa muri rusange ni 0.45-0.51mm.Mw'ijambo, uko ubunini bw'umuringa buringaniye, niko ruto rurwanya, niko intera yohereza ari.

Ukurikije ibipimo bya Ethernet, intera ntarengwa yo kohereza na PoE ni metero 100, bivuze ko POE ihindura ikoresha insinga mpuzamahanga zisanzwe zikoreshwa mumashanyarazi zigarukira muri metero 100 nazo.Kurenza metero 100, amakuru arashobora gutinda no gutakaza.Kugirango tumenye neza umushinga, muri rusange dufata metero 80-90 za cabling.

Bamwe mu bakora cyane POE bahindura bavuga ko bashoboye kohereza ibimenyetso bigera kuri metero 250 mumurongo wa 100Mbps, nukuri?

Nibyo, ariko ihererekanyabubasha ryagabanutse kuva kuri 100Mbps kugera kuri 10Mbps (umurongo wa interineti), hanyuma intera yohereza ibimenyetso irashobora kwaguka kugera kuri metero 250 (umugozi ufite intanga zidafite ogisijeni).Iri koranabuhanga ntirishobora gutanga umurongo mwinshi;Ibinyuranye na byo, umurongo wa interineti uhagarikwa kuva 100Mbps ukagera kuri 10Mbps, kandi ntabwo ari byiza mu buryo bworoshye bwo gusobanura neza amashusho yo gukurikirana.10Mbps bivuze ko ibice 2 cyangwa 3 gusa bya 4MP ya kamera ya IP ishobora kugerwaho kuriyi nsinga ya Cat5e, buri kamera ya 4MP ya IP ni Max 2-3Mbps muri Dynamic scene.Mu ijambo, umugozi wa Cat5e nturenze metero 100 muri cabling.

Umuyoboro wa ELZONETA Cat5e ukoresha intungamubiri nziza ya ogisijeni idafite umubyimba wa 0.47mm wumuringa, kugirango uhuze kamera ya PoE IP hamwe nu murongo wo mu rwego rwo hejuru wa PoE.Ibi nkibi byerekana kohereza no gutanga amashanyarazi kuri sisitemu yose yo kugenzura CCTV.
