Kuhlelo lwekhamera ye-IP kanye nesistimu ye-cabling yenethiwekhi engu-100Mbps, sivame ukusebenzisa intambo yenethiwekhi ye-Cat5e ukuze sidlulise isignali kanye nokunikezwa kwamandla.I-Elzoneta izokuchazela ulwazi oluyisisekelo njengoba ngezansi:
Ungayisebenzisa kanjani i-PoE power supply?
Ngokunikezwa kwamandla, kufanele sibe nombono we-PoE kuqala.I-PoE (Amandla phezu kwe-Ethernet), isho ukuthi amandla kagesi aphuma ku-PoE eshintshela kumatheminali asekelwe ku-IP (njengefoni ye-IP, indawo yokufinyelela ye-wlan namakhamera we-IP) ngentambo yenethiwekhi ye-Cat5e.Yiqiniso, kokubili ama-switch kanye namatheminali asekelwe ku-IP anemojula ye-PoE eyakhelwe ngaphakathi;Uma amatheminali asekelwe ku-IP engenayo imojuli ye-PoE, idinga ukusebenzisa isihlukanisi se-Standard PoE.
Ngokuvamile, sikhetha ukusebenzisa iswishi ye-PoE ejwayelekile yamazwe ngamazwe, esekela i-48V-52V, ilandela i-IEEE802.3af/802.3at.Ngoba le swishi ye-PoE inomsebenzi wokubona ohlakaniphile we-PoE.Uma sisebenzisa inkinobho ye-PoE engajwayelekile, i-12V noma i-24V, ngaphandle komsebenzi we-PoE smart detect, lapho amandla kagesi aphuma kumatheminali asekelwe ku-IP ngokuqondile kungakhathaliseki ukuthi anemojula ye-PoE eyakhelwe ngaphakathi noma cha, kulula ukushisa izimbobo zamatheminali asekelwe ku-IP. , ngisho nokulimaza imojula yabo yamandla.
Kukude kangakanani ukudluliswa kwesignali?
Ibanga lokudlulisela lekhebula lenethiwekhi lincike ezintweni zekhebula.Imvamisa, idinga ukusebenzisa ithusi elingenawo umoya-mpilo, ngoba ukumelana nethusi elingenawo umoya-mpilo kuncane, ngaphakathi kwama-ohm angama-30 ngamamitha angama-300, futhi usayizi wethusi oyinhloko ngokuvamile ngu-0.45-0.51mm.Ngamafuphi, uma umkhulu usayizi womongo wethusi, ukuncipha kokumelana, ibanga lokudlulisela liya phambili.
Ngokwezinga le-Ethernet, ibanga elikhulu lokudlulisa isignali nge-PoE switch lingamamitha ayi-100, okusho ukuthi ukushintshwa kwe-POE kusebenzisa izintambo zenethiwekhi ezijwayelekile zamazwe ngamazwe ukuze kunikezwe amandla kagesi akhawulelwe kumamitha ayi-100 futhi.Ngaphezu kwamamitha angu-100, idatha ingase ibambezeleke futhi ilahleke.Ukuze siqinisekise ikhwalithi yephrojekthi, ngokuvamile sithatha amamitha angu-80-90 ukuze kufakwe ikhebula.
Amanye amaswishi e-POE asebenza kahle kakhulu athi ayakwazi ukudlulisa amasiginali afinyelela kumamitha angama-250 kunethiwekhi ye-100Mbps, ingabe kuyiqiniso?
Yebo, kodwa ukudluliswa kwesignali kuncishisiwe kusuka ku-100Mbps kuya ku-10Mbps (umkhawulokudonsa), bese ibanga lokudlulisela isignali linganwetshwa libe ngamamitha angu-Max 250 (ikhebula elinomgogodla wethusi ongenawo umoya-mpilo).Lobu buchwepheshe abukwazi ukuhlinzeka ngomkhawulokudonsa ophezulu;Ngokuphambene nalokho, umkhawulokudonsa ucindezelwa ukusuka ku-100Mbps ukuya ku-10Mbps, futhi okungekuhle ekudluliseni okubushelelezi kwencazelo ephezulu yezithombe zokuqapha.I-10Mbps isho izingcezu ezi-2 noma ezi-3 kuphela zamakhamera we-4MP IP ezingafinyelelwa kule ntambo ye-Cat5e, umkhawulokudonsa wekhamera ye-4MP IP ngayinye ungu-Max 2-3Mbps esigcawini se-Dynamic.Ngamafuphi, ikhebula lenethiwekhi ye-Cat5e alikho ngaphezu kwamamitha ayi-100 kukhebula.
Intambo yenethiwekhi ye-ELZONETA Cat5e isebenzisa umongo ophezulu omsulwa ongenawo umoya-mpilo nobubanzi obungu-0.47mm wethusi, ukuze ifane nekhamera ye-PoE IP kanye neswishi ye-PoE esezingeni eliphezulu.Lokhu kuqinisekisa ukudluliswa kwesignali nokuzinza kokunikezwa kwamandla kulo lonke uhlelo lokugada lwe-CCTV.
