Ungaxhuma kanjani i-PoE switch nekhamera ye-IP?

Namuhla,JHAI-Tech izokwethula izindlela zohlelo lokusebenza zeUkushintsha kwe-POEkumaphrojekthi athile kanye namasu ethu okuphendula okusebenzisa ukushintshwa okunamandla e-POE ezimeni ezahlukene.

Amatheminali edivayisi asekela i-POE ahlanganisa ama-AP angenawaya, amakhamera enethiwekhi, njll. Ukuxhumana phakathi kwetheminali kanye neswishi kwenziwa ngamakhebuli enethiwekhi. Sizohlukanisa ukuxhumana kube izinhlobo ezi-4 ngokusekelwe ekutheni ibhokisi letheminali kanye nokushintshanisa i-POE yokusekela.

Okokuqala, iswishi kanye netheminali zombili zisekela i-POE.

Okwesibili, inkinobho isekela i-POE, kodwa i-terminal ayisekeli i-POE.

Okwesithathu, iswishi ayisekeli i-POE, kodwa itheminali iyayisekela i-POE.

Okwesine, iswishi noma itheminali ayisekeli i-POE.

Icala lokuqala lokusekela ngesikhathi esisodwa lilula kakhulu. IShintshanisa amasheya PoEixhunywe ngokuqondile ku-AP engenantambo noma ikhamera yenethiwekhi esekela ukunikezwa kwamandla kwe-POE.

Qiniseka ukuthi ikhwalithi yekhebuli yenethiwekhi isezingeni, ngoba sihlangabezane nokunikezwa kwamandla okungazinzile kwe-AP noma kwe-IPC ngenxa yekhwalithi yekhebula lenethiwekhi eliphansi. Namuhla, umngane ushiye umlayezo ngemuva ebuza ukuthi ibanga lekhebula lenethiwekhi yekhamera yenethiwekhi lingasekela amamitha angu-130-150 njengoba umthengisi eshilo. Kungcono ukuthi sigcine ikhebula lenethiwekhi phakathi kwamamitha angu-80, ngoba isignali izoncishiswa kude, futhi noma ingabonakali, kuzoba nezingozi ezifihliwe esikhathini esizayo.

Elinye iphuzu yilokho esikushilo esihlokweni esandulele. Udinga ukunaka ukuthi ingabe itheminali neswishi kungamadivayisi ajwayelekile e-POE. Imishini ejwayelekile nengajwayelekile ingaxutshwa futhi isetshenziswe.

Icala lesibili ukuthi iswishi isekela i-POE, kodwa itheminali ayisekeli i-POE. Esinye isiphetho sekhebula lenethiwekhi eliphuma ekushintsheni kufanele lixhunywe kusihlukanisi se-POE, esisethule futhi. Isignali yokudlulisela ihlukaniswe ngesignali yedatha namandla.

Uhlobo lwesithathu yilapho iswishi ingasekeli i-POE kodwa itheminali iyayisekela. Iswishi ixhunywe kugesi we-POE. Ngokungafani nesihlukanisi, ugesi we-POE ungangeza amandla kukhebuli yenethiwekhi bese udlulisela isignali kutheminali.

Uhlobo lwesine yisimo lapho iswishi noma itheminali ifakwe khona. Abanye abangani babuze ukuthi bathini ngalesi simo. Uma ingahlonyisiwe, vele ulandele uhlelo lokuqala. Njengoba sikhuluma ngokunikezwa kwamandla e-POE, uma kungekho okusekelwayo, sizimisele futhi ukusizakala ngezinzuzo zokuhlinzekwa kwamandla ka-POE (yize kungenzeki, sikhuluma ngobuchwepheshe kuphela), okungukuthi, xhuma imishini zombili iziphetho, xhuma iswishi kugesi we-POE, bese uxhuma enye ingxenye yentambo yenethiwekhi kusihlukanisi se-POE, bese ekugcineni uyidlulisele kutheminali.

Izimo ezine ezingenhla zichaza zonke izimo lapho ugesi we-POE ungasetshenziswa khona. Ngaphezu kwalokho, ukukhethwa kwe-POE switch nakho kubaluleke kakhulu. Ukushintsha okuhle kwe-POE akukwazi nje ukwenza isistimu ukuthi izinze kodwa futhi kusiza ukugcinwa nokuthuthukiswa kwesikhathi esizayo.
