一.Kodi kusintha kwa PoE ndikokulirapo kwabwinoko?
Popeza pali zida zambiri zamphamvu kwambiri pazida zowunikira pano, opanga ma switch amakonda kupanga ma switch a PoE ndi mphamvu yayikulu. Komabe, zinthu zambiri pamsika zimangotsatira kuperekedwa kwa mphamvu zonse, ndipo osaganizira kuchuluka kwa madoko. Mphamvu ikawonjezeka, mtengo wonse wa zidawo udzakweranso, motero mtengo wogula udzakwera mwachilengedwe. Chifukwa chake, ogwiritsa ntchito akagula, ayenera kusankha chosinthira choyenera malinga ndi momwe zinthu ziliri, osati mphamvu yapamwamba, yabwinoko.
二.Ndi zoopsa zotani za PoE panthawi yamagetsi?
1. Mphamvu zosakwanira
820.af mphamvu yotulutsa mphamvu ya PoE ndi yochepa kuposa 15.4w, yomwe ndi yokwanira kwa IPC, koma kwa PD yamphamvu kwambiri, mphamvu yotulutsa mphamvuyo siyingakwaniritse zofunikira;
2. Zowopsa ndizokhazikika kwambiri
Nthawi zambiri, kusintha kwa PoE kudzapereka mphamvu kuma IPC angapo akutsogolo nthawi imodzi. Ngati gawo lamagetsi la switch likulephera, lidzakhudza ntchito ya makamera onse, ndipo chiwopsezo chimakhala chokhazikika;
3. Zida zapamwamba komanso ndalama zosamalira
Poyerekeza ndi njira zina zoperekera magetsi, ukadaulo wamagetsi wa PoE udzakulitsa ntchito yokonza pambuyo pakugulitsa. Kuchokera pamalingaliro achitetezo, kukhazikika kwamagetsi amodzi ndikobwino kwambiri.
三.Kodi mtunda wotetezedwa wamagetsi a PoE ndi wotani?
Mtunda wotetezedwa wamagetsi a POE ndi 100 metres, ndipo tikulimbikitsidwa kugwiritsa ntchito chingwe chapamwamba chamkuwa. Direct current imatha kufalikira patali kwambiri ndi zingwe zokhazikika za Efaneti, ndiye chifukwa chiyani mtunda wotumizira umakhala wochepera mamita 100? Chowonadi ndi chakuti mtunda wautali wotumizira wosinthira wa PoE makamaka umadalira mtunda wotumizira deta. Pamene mtunda wotumizira uposa mamita 100, kuchedwa kwa deta ndi kutayika kwa paketi kumatha kuchitika. Choncho, pakumanga kwenikweni, mtunda wotumizira suyenera kupitirira mamita 100. Komabe, pali kale masiwichi a PoE omwe amatha kufikira mtunda wotumizira wa 250 metres, womwe ndi wokwanira kuperekera mphamvu mtunda wautali. Akukhulupiriranso kuti ndi chitukuko chaukadaulo wamagetsi a PoE posachedwa, mtunda wotumizira udzakulitsidwa patali.
四.Kodi ndiyenera kugula chosinthira cha PoE chokhazikika? Kodi zosavomerezeka zingagwiritsidwe ntchito?
Sankhani muyezo kapena osakhala muyezo, izi makamaka zimadalira magetsi AP, IP
Kodi Kamera imathandizira mphamvu yanji? 48, 24, 12 v. Ngati ndi 48v, muyenera kusankha kusintha kwa PoE; ngati ndi 24 kapena 12v, muyenera kupeza lolingana sanali muyezo lophimba, ndithudi, muyezo ndi zotheka, koma ngati mugula muyezo, muyenera okonzeka ndi PD splitter.
Kuchokera ku kufotokozera, titha kuwona kuti nthawi zina zosintha zosakhazikika zimapezekanso, ndipo mtengo udzakhala wotsika, komabe tikukukumbutsani kuti mugule masiwichi okhazikika. Chifukwa chosinthika chosasinthika sichikhala ndi chipangizo cha PoE ndipo sichizindikira chipangizocho, n'zosavuta kupanga kachigawo kakang'ono kuti kawotche chipangizocho, chomwe chingawotche doko powala, kapena kuyambitsa moto pazovuta kwambiri; pomwe chosinthira chokhazikika chidzayesedwa chikayatsidwa kuti chisawotche chipangizocho.
五.Momwe mungasankhire chosinthira cha PoE chowunikira chitetezo komanso kuphimba opanda zingwe?
Pali mitundu yambiri ya ma switch a PoE, kuyambira 100M mpaka 1000M, mpaka gigabit yodzaza, komanso kusiyana pakati pa mitundu yosayendetsedwa ndi yoyendetsedwa, komanso kusiyana kwa madoko osiyanasiyana. Ngati mukufuna kusankha chosinthira choyenera, muyenera kuganizira mozama komanso mozama. . Tengani pulojekiti yomwe imafuna kuyang'anitsitsa kwapamwamba monga chitsanzo.
1. Sankhani chosinthira cha PoE chokhazikika
2. Sankhani 100M kapena 1000M lophimba
Mu yankho lenileni, m'pofunika kuphatikiza chiwerengero cha makamera, ndi kusankha magawo monga kamera kusamvana, pang'ono mlingo, ndi chimango nambala. Opanga zida zowunikira adzapereka zida zowerengera za bandwidth, ndipo ogwiritsa ntchito amatha kugwiritsa ntchito zidazo kuwerengera bandwidth yomwe ikufunika ndikusankha kusintha koyenera kwa PoE.
3. Sankhani af kapena pakusintha kwa PoE
Sankhani molingana ndi mphamvu yowunikira zida. Mwachitsanzo, ngati kamera yamtundu wodziwika bwino imagwiritsidwa ntchito, mphamvuyo ndi 12W max. Pankhaniyi, kusintha kwa af standard kuyenera kusankhidwa. Mphamvu ya kamera yodziwika bwino kwambiri ndi 30W max. Pankhaniyi, ndikofunikira kugwiritsa ntchito switch pa-standard.
Chachinayi, sankhani kuchuluka kwa madoko pa switch
Malinga ndi kuchuluka kwa madoko, masinthidwe a PoE amatha kugawidwa m'madoko 4, madoko 8, madoko 16 ndi madoko 24, ndi zina zambiri, zomwe zimatha kuwunika mozama mphamvu, kuchuluka, malo a zida, kusintha magetsi ndi kusankha kwamitengo.
