Ngabe injector ye-PoE isebenza kanjani?

Lapho amaswishi noma amanye amadivaysi angenawo umsebenzi wokuphakelwa kwamandla exhunywe kumadivayisi anikwe amandla (njengamakhamera e-IP, ama-APs angenawaya, njll.), ukunikezwa kwamandla kwe-PoE kungahlinzeka ngosekelo lokudlulisa amandla kanye nedatha kulawa madivayisi anikwe amandla ngesikhathi esifanayo, ngokudlulisela ibanga elingafika ku-100 Meter.Ngokuvamile, ugesi we-PoE uqala ngokuguqulela amandla e-AC kumandla e-DC, bese unikeza amandla kumshini wetheminali we-PoE ene-voltage ephansi.

Ungayisebenzisa kanjani i-PoE injector?

Kule ngxenye, sisebenzisa kakhulu amakhamera we-IP anikwe amandla i-PoE (noma amanye amadivaysi etheminali e-PoE) njengesibonelo ukuze sichaze ukuthi zisetshenziswa kanjani izijovo zikagesi ze-PoE namaswishi angewona e-PoE ukuze sinikeze amandla.Izinto ezizolungiswa yilezi: amakhamera we-IP amaningana, izinsiza zamandla ze-PoE (inombolo idinga ukunqunywa ngokwenani lamakhamera we-IP), ukushintshwa okujwayelekile okungeyona i-PoE kanye nezintambo eziningana zenethiwekhi (Cat5eCat6Cat6a).
1. Hlola zonke izinto zokusebenza kuqala ukuze uqinisekise ukuthi ikhamera ye-IP, ukunikezwa kwamandla kwe-PoE kanye nesistimu yokuphatha ikhamera konke kusebenza ngendlela evamile.Ngaphambi kokufaka ikhamera, qedela ukucushwa kwenethiwekhi okuhlobene nekhamera kusenesikhathi.
2. Ngemva kokuqedwa kwesinyathelo sokuqala, sebenzisa intambo yenethiwekhi ukuxhuma ikhamera endaweni kagesi yokuphakelwa kukagesi kwe-PoE.
3. Okulandelayo, faka ikhamera endaweni ekhanyiswe kahle ukuze wenze isithombe esithathwe yikhamera sicace kakhudlwana.
4. Sebenzisa enye ikhebula yenethiwekhi ukuxhuma imbobo yokudluliswa kwedatha yeswishi kanye nendawo kagesi.
5. Ekugcineni, xhuma intambo yamandla kagesi endaweni yamandla ye-AC eseduze.

Yiziphi izici okufanele zicatshangelwe lapho uthenga i-PoE Injector?

*Inombolo yamadivayisi anikwe amandla: Uma kukhona idivayisi eyodwa kuphela enamandla, ukunikezwa kwamandla kwe-PoE yembobo eyodwa kwanele.Uma kunamadivayisi amaningi wetheminali ye-PoE, udinga ukuqinisekisa ukuthi inombolo yezimbobo zokujova amandla e-PoE iyafana.
*Usayizi wokuphakelwa kwamandla wembobo eyodwa ye-PoE: Kuyadingeka ukuqinisekisa ukuthi ukunikezwa kwamandla kanye nedivayisi yokwamukela amandla exhunyiwe kuhlangabezana nezinga elifanayo le-PoE.Ngokuvamile kunamazinga amathathu okunikezwa kwamandla e-PoE: 802.3af (PoE), 802.3at (PoE+), kanye ne-802.3bt (PoE++).Osayizi bawo abakhulu abahambisana nawo bangu-15.4W, 30W, kanye no-60W/100W ngokulandelanayo.
*I-voltage yokuphakelwa kwamandla: Qiniseka ukuthi i-voltage yokusebenza kwamandla kagesi kanye nedivayisi yokwamukela amandla exhunyiwe kuyahambisana.Isibonelo, amakhamera amaningi okugada asebenza ku-12V noma ku-24V.Kuleli qophelo, udinga ukunaka ukuze uqinisekise ukuthi inani le-voltage yokuphakelwa kwamandla kagesi we-PoE lifana nevelu ye-voltage yokusebenza yekhamera ukugwema ukugcwala kwamandla kagesi noma ukwehluleka ukusebenza.

I-FAQ ye-PoE Injector:

Q: Ingabe amandla okuphakela amandla e-PoE ku-switch ye-gigabit?
A: Cha, ngaphandle uma isishintshi se-gigabit sinembobo yamandla ye-PoE.

Q: Ingabe ugesi we-PoE unechweba lokulawula abaphathi?
A: Cha, ukunikezwa kwamandla kwe-PoE kunganikeza amandla ngokuqondile kumadivayisi anikwe amandla e-PoE ngomshini wokuphakela amandla, ipulaki nokudlala.Ngaphezu kwalokho, iphinde ibe nomsebenzi wokuvikela wesifunda esifushane, ongahlinzeka ngokuqondile okwamanje kumadivayisi angenawaya kanye nemishini yokuqapha.Uma udinga idivayisi kagesi ye-PoE enezici zokuphatha, ungakhetha ukushintsha kwe-PoE.
