Chingwe chapaintaneti cha Cat5e: Momwe mungagwiritsire ntchito magetsi a PoE?Kodi kutumizira ma signal kuli patali bwanji?

Mu IP camera system ndi 100Mbps network cabling system, nthawi zambiri timagwiritsa ntchito chingwe cha Cat5e network potumiza siginecha ndi magetsi.Elzoneta ikufotokozerani zina zofunika kwa inu monga pansipa:

Momwe mungagwiritsire ntchito magetsi a PoE?

Kuti tipeze magetsi, tiyenera kukhala ndi lingaliro la PoE poyamba.PoE (Power over Ethernet), kutanthauza kuti mphamvu yamagetsi imachokera ku PoE switch kupita ku IP-based terminals (monga IP phone, wlan access point ndi makamera a IP) kudzera pa chingwe cha netiweki cha Cat5e.Zachidziwikire, ma switch ndi ma IP-based terminals ali ndi gawo la PoE;Ngati ma terminals a IP alibe gawo la PoE, ayenera kugwiritsa ntchito ziboda za Standard PoE.

Nthawi zambiri, timasankha kugwiritsa ntchito kusintha kwa PoE padziko lonse lapansi, komwe kumathandizira 48V-52V, kumatsatira IEEE802.3af/802.3at.Chifukwa chosinthira cha PoE ichi chili ndi ntchito yozindikira ya PoE.Ngati tigwiritsa ntchito osakhala muyezo PoE lophimba, 12V kapena 24V, popanda PoE anzeru zindikirani ntchito, pamene linanena bungwe mphamvu yamagetsi ku materminal ofotokoza IP mwachindunji mosasamala kanthu anamanga-PoE module kapena ayi, n'zosavuta kuwotcha IP-based terminals madoko. , ngakhale kuwononga gawo lawo lamphamvu.

Kodi kutumizira ma signal kuli patali bwanji?

Kufala mtunda wa chingwe maukonde zimadalira zipangizo chingwe.Nthawi zambiri, imayenera kugwiritsa ntchito mkuwa wopanda okosijeni, chifukwa kukana kwa mkuwa wopanda okosijeni ndikocheperako, mkati mwa 30 ohms kwa 300 metres, komanso kukula kwa mkuwa nthawi zambiri kumakhala 0.45-0.51mm.M'mawu amodzi, kukula kwa mkuwa wapakati, kumachepetsa kukana, ndipamenenso mtunda wotumizira umakhala wotalikirapo.

Malinga ndi mulingo wa Ethernet, mtunda wopitilira ma siginecha wa PoE ndi 100 metres, zomwe zikutanthauza kuti kusintha kwa POE kumagwiritsa ntchito zingwe zapadziko lonse lapansi kuti magetsi azikhala ndi malire pamamita 100 nawonso.Kupitilira mamita 100, deta ikhoza kuchedwa ndikutayika.Kuti tiwonetsetse kuti ntchitoyo ndi yabwino, nthawi zambiri timatenga 80-90 metres kuti tipange cabling.

Zosintha zina za POE zogwira ntchito kwambiri zimati zimatha kutumiza ma siginecha mpaka 250 metres mu netiweki ya 100Mbps, sizoona?

Inde, koma kufala chizindikiro yafupika 100Mbps kuti 10Mbps (bandiwifi), ndiyeno chizindikiro kufala mtunda akhoza anawonjezera kuti Max 250 mamita (chingwe ndi mpweya wopanda mkuwa pachimake).Ukadaulo uwu sungapereke bandwidth yapamwamba;M'malo mwake, bandiwifi ndi wothinikizidwa kuchokera 100Mbps kuti 10Mbps, ndi amene si abwino kwa yosalala mkulu-tanthauzo kufala kwa zithunzi polojekiti.10Mbps imatanthawuza kuti zidutswa ziwiri kapena 3 zokha za makamera a 4MP IP zitha kupezeka ku chingwe cha Cat5e, bandwidth iliyonse ya 4MP IP kamera ndi Max 2-3Mbps mu Dynamic scene.Mwachidule, chingwe cha netiweki cha Cat5e sichimapitilira 100 metres.

Chingwe cha netiweki cha ELZONETA Cat5e chimagwiritsa ntchito pachimake chopanda mpweya wabwino kwambiri chokhala ndi mainchesi a 0.47mm amkuwa, kuti agwirizane ndi kamera ya PoE IP ndi kusintha kwapamwamba kwa PoE.Izi zimatsimikizira kufalikira kwa ma siginecha komanso kukhazikika kwamagetsi pamayendedwe onse owunikira a CCTV.
