Sisebenza njani isitofu se-PoE?

Xa iiswitshi okanye ezinye izixhobo ngaphandle kokusebenza kwamandla ombane zixhunywe kwizixhobo ezinamandla (ezifana neekhamera ze-IP, i-wireless APs, njl.), Umbane we-PoE unokubonelela ngenkxaso yombane kunye nokuhanjiswa kwedatha kwezi zixhobo ezinamandla ngexesha elifanayo, kunye nokuhanjiswa. umgama ukuya kuthi ga kwi-100 yeemitha.Ngokubanzi, unikezelo lwamandla lwe-PoE luqala luguqulela amandla e-AC kumandla e-DC, kwaye emva koko lunike amandla kwisixhobo esinomthamo ophantsi we-PoE.

Uyisebenzisa njani i-PoE injector?

Kule nxalenye, sisebenzisa kakhulu iikhamera ze-IP ezinikwe amandla e-PoE (okanye ezinye izixhobo ze-terminal ye-PoE) njengomzekelo wokuchaza indlela yokusebenzisa ii-injection zamandla e-PoE kunye neeswitshi ezingezizo ze-PoE ukunika amandla.Izixhobo eziza kulungiswa kukuba: iikhamera ezininzi ze-IP, izixhobo ezininzi zombane ze-PoE (inani lifuna ukuqinisekiswa ngokwenani leekhamera ze-IP), i-standard non-PoE switch kunye neentambo ezininzi zenethiwekhi (Cat5eCat6Cat6a).
1. Vavanya zonke izixhobo kuqala ukuqinisekisa ukuba ikhamera ye-IP, umbane we-PoE kunye nenkqubo yokulawula ikhamera zonke zisebenza ngokuqhelekileyo.Ngaphambi kokufaka ikhamera, gqibezela ubumbeko lwenethiwekhi ehambelana nekhamera kwangaphambili.
2. Emva kokuba isinyathelo sokuqala sigqityiwe, sebenzisa intambo yenethiwekhi ukudibanisa ikhamera kwi-port yombane ye-PoE power supply.
3. Okulandelayo, fakela ikhamera kwindawo ekhanyiswe kakuhle ukwenza umfanekiso othathwe yikhamera ucace ngakumbi.
4. Sebenzisa enye intambo yenethiwekhi ukudibanisa i-port yothumelo lwedatha yokutshintsha kunye nokunikezelwa kwamandla.
5. Okokugqibela, plaga intambo yombane yobonelelo lwamandla kwindawo ekufutshane yombane we-AC.

Zeziphi izinto ekufuneka ziqwalaselwe xa kuthengwa i-PoE Injector?

*Inani lezixhobo ezinikwe amandla: Ukuba kukho isixhobo esinamandla esinye kuphela, unikezelo lwamandla lwe-PoE olunezibuko elinye lwanele.Ukuba kukho izixhobo ezininzi ze-terminal ye-PoE, kufuneka uqinisekise ukuba inani le-PoE yesitofu samandla sezibuko liyahambelana.
*Ubungakanani bonikezelo lwamandla ezibuko elinye le-PoE: Kuyafuneka ukuqinisekisa ukuba unikezelo lwamandla kunye nesixhobo sokufumana umbane esidityanisiweyo sihlangabezana nomgangatho ofanayo we-PoE.Ngokuqhelekileyo kukho imigangatho emithathu yonikezelo lwamandla e-PoE: 802.3af (PoE), 802.3at (PoE +), kunye ne-802.3bt (PoE ++).Ubukhulu bawo obuhambelana nobukhulu bokubonelela ngamandla yi-15.4W, 30W, kunye ne-60W / 100W ngokulandelelanayo.
*Amandla ombane ombane: Qinisekisa ukuba umbane osebenzayo wobonelelo lwamandla kunye nesixhobo sokufumana umbane esidityanisiweyo siyahambelana.Ngokomzekelo, iikhamera ezininzi zokucupha zisebenza kwi-12V okanye i-24V.Ngeli xesha, kufuneka ubeke ingqalelo yokuqinisekisa ukuba ixabiso lamandla ombane wobonelelo lwamandla ombane we-PoE lihambelana nexabiso lombane osebenzayo wekhamera ukunqanda ukugcwala kombane okanye ukusilela kokusebenza.

FAQ yePoE Injector:

Umbuzo: Ngaba i-PoE yonikezelo lwamandla amandla ombane kwi-gigabit switch?
A: Hayi, ngaphandle kokuba i-gigabit switch ine-port yamandla ye-PoE.

Umbuzo: Ngaba unikezelo lwamandla lwe-PoE lunezibuko lolawulo lolawulo?
A: Hayi, unikezelo lwamandla lwe-PoE lunokubonelela ngokuthe ngqo amandla kwizixhobo ze-PoE ngesixhobo sokubonelela ngombane, iplagi kunye nokudlala.Ukongeza, inomsebenzi wokukhusela omfutshane, onokubonelela ngokuthe ngqo ngoku ngokuthe ngqo kwizixhobo ezingenazintambo kunye nezixhobo zokubeka iliso.Ukuba ufuna isixhobo sombane se-PoE esinemisebenzi yokulawula, unokukhetha ukutshintshela kwe-PoE.
