Kwinkqubo yekhamera ye-IP kunye ne-100Mbps yenethiwekhi ye-cabling system, sihlala sisebenzisa intambo yenethiwekhi ye-Cat5e ukuhambisa umqondiso kunye nokubonelela ngombane.U-Elzoneta uya kukucacisela ulwazi olusisiseko njengoko lungezantsi:
Usetyenziswa njani unikezelo lwamandla lwe-PoE?
Ukubonelela ngombane, kufuneka sibe nombono wePoE kuqala.I-PoE (Amandla phezu kwe-Ethernet), ithetha ukuba amandla ombane aphuma kwi-PoE ukutshintshela kwii-terminals ezisekelwe kwi-IP (ezifana ne-IP yefowuni, indawo yokufikelela kwi-wlan kunye neekhamera ze-IP) nge-Cat5e network cable.Ngokuqinisekileyo, zombini i-switch kunye ne-IP-based terminals inemodyuli ye-PoE eyakhelwe ngaphakathi;Ukuba iitheminali ezisekwe kwi-IP azinayo imodyuli ye-PoE, kufuneka isebenzise i-Standard PoE splitter.
Ngokuqhelekileyo, sikhetha ukusebenzisa iswitshi ye-PoE esemgangathweni yamazwe ngamazwe, exhasa i-48V-52V, ilandela i-IEEE802.3af/802.3at.Kuba olu tshintsho lwe-PoE lunomsebenzi we-PoE smart detect.Ukuba sisebenzisa i-non-standard PoE switch, i-12V okanye i-24V, ngaphandle kwe-PoE smart detect function, xa amandla ombane aphuma kwii-terminals ezisekelwe kwi-IP ngokuthe ngqo kungakhathaliseki ukuba bakhelwe kwimodyuli ye-PoE okanye akunjalo, kulula ukutshisa izibuko ze-IP-based. , nokuba yonakalisa imodyuli yabo yamandla.
Kukude kangakanani ukuhanjiswa komqondiso?
Umgama wothumelo lwentambo yenethiwekhi ixhomekeke kwizinto zentambo.Ngokuqhelekileyo, kufuneka kusetyenziswe ubhedu olungenayo i-oksijini, kuba ukuxhathisa ubhedu olungenayo i-oksijini kuncinci, ngaphakathi kwe-30 ohms yeemitha ezingama-300, kunye nobukhulu be-copper core ngokubanzi 0.45-0.51mm.Ngelizwi, ubukhulu besiseko sobhedu, incinci ukuchasana, ngakumbi umgama wothumelo.
Ngokomgangatho we-Ethernet, umgama omkhulu wokuhanjiswa komqondiso ngotshintsho lwe-PoE ziimitha ezili-100, okuthetha ukuba ukutshintshela kwe-POE kusebenzisa iintambo zenethiwekhi ezisemgangathweni zamazwe ngamazwe zobonelelo lwamandla lulinganiselwe kwiimitha ezili-100 kakhulu.Ngaphezulu kweemitha ezili-100, idatha inokulibaziseka kwaye ilahleke.Ukuze siqinisekise umgangatho weprojekthi, sithatha ngokubanzi i-80-90 yeemitha kwi-cabling.
Ezinye iiswitshi ze-POE ezisebenza kakhulu zibanga ukuba ziyakwazi ukuthumela imiqondiso ukuya kuthi ga kwiimitha ezingama-250 kwinethiwekhi ye-100Mbps, ngaba yinyani?
Ewe, kodwa ukuhanjiswa komqondiso kuncitshisiwe ukusuka kwi-100Mbps ukuya kwi-10Mbps (i-bandwidth), kwaye ke umgama wokuhambisa umqondiso unokwandiswa ukuya kwi-Max 250 yeemitha (intambo ene-oxygen-free copper core).Le teknoloji ayikwazi ukubonelela nge-bandwidth ephezulu;Ngokuchasene noko, i-bandwidth ixinzelelwe ukusuka kwi-100Mbps ukuya kwi-10Mbps, kwaye ayilunganga ukuhanjiswa kwenkcazo ephezulu yokujonga imifanekiso.I-10Mbps ithetha kuphela iziqwenga ezi-2 okanye ezi-3 zeekhamera ze-4MP ze-IP ezinokufikelelwa kule ntambo ye-Cat5e, i-bandwidth nganye yekhamera ye-4MP yi-Max 2-3Mbps kwindawo yeDynamic.Ngelizwi nje, intambo yenethiwekhi yeCat5e ayikho ngaphezu kweemitha ezili-100 kwikhebula.
Intambo yenethiwekhi ye-ELZONETA Cat5e isebenzisa i-high pure pure-free core kunye ne-0.47mm ye-copper core diameter, ukufanisa ikhamera ye-PoE IP kunye nomgangatho ophezulu we-PoE switch.Oku kuqinisekisa ukuhanjiswa komqondiso kunye nokuzinza kobonelelo lwamandla kuyo yonke inkqubo yokucupha yeCCTV.
