Uphononongo lwe Zyxel GS12-1350HP 12-port smart elawulwa gigabit PoE switsha nge gigabit uplink kunye nexabiso. .
Nabani na ojonga phantsi kwekati usengozini yokuyifumana simahla.
Malunga neZyxel
Inkampani yoluntu enekomkhulu eTaiwan, ikhethekileyo kwimveliso yezixhobo zothungelwano zekhaya kunye neshishini ukusukela ngo-1989. kwiTaiwan Stock Exchange. Ibe , into endiyithethayo kukuba ngenkxaso ungaya ngqo kubo.
I-GS1350 - uchungechunge olukhethekileyo lokutshintsha kwe-PoE elawulwayo kwiinkqubo zokucupha ividiyo
Umgama ophezulu kwikhamera yi-250 yeemitha
Ukutshintsha kwe-Standard PoE kukuvumela ukuba uthumele umqondiso kumgama ongekho ngaphezu kweemitha ezili-100. Uluhlu lwe-GS1350 lwe-Zyxel olulawulwayo olutshintshileyo olulungiselelwe iinkqubo zokucupha iividiyo zisombulula ngokupheleleyo le ngxaki, ukwandisa umgama ophezulu kwizixhobo ezinamandla ukuya kwiimitha ze-250, eziququzelela kakhulu ukuthunyelwa kweenkqubo zokucupha ividiyo.
Ukubuyisela ikhamera ngokuzenzekelayo
Ngokukhawuleza emva kokubona ukungaphumeleli kwekhamera ye-IP, utshintsho luyiqala ngokuzenzekelayo kwaye luzama ukubuyisela ukusebenza kwayo.
Ubume beekhamera ze-IP buchongwa ngeprotocol , kwaye ngokunjalo
ukuthumela iipakethe.
Ubonelelo lwamandla oluqhubekayo lwe-PoE
Ukutshintsha ngokuqhubekayo kunika amandla kwiikhamera ze-IP naxa uhlaziya i-firmware okanye uqwalaselo, oluphucula kakhulu ukuqhubeka kwenkqubo yokujonga ividiyo. Olu phawu luqinisekisa unikezelo lwamandla oluqhubekayo kwiikhamera kunye nezinye izinzwa ngelixa iswitshi igcinwa.
Ukongeza ekusebenzeni okuqhelekileyo, kukho amaxesha apho kuyimfuneko ukwenza izenzo ezithile ngokutshintsha, umzekelo:
- yenza uhlaziyo lwe-firmware
- layisha ifayile yoqwalaselo entsha, okanye, ngokuchaseneyo, buyisela ezi zangoku
- izicwangciso kwezidlulileyo ukusuka kwikopi yogcino
- phinda useto lwefektri
Kwakhona, ngamanye amaxesha kukho imfuneko yokuphinda uqalise kwakhona iswitshi,
umzekelo, ukujonga ukuba useto lwenziwe ngokuchanekileyo.
Iinkcukacha ezingakumbi malunga nemodeli ye-GS1350-12HP
Ukugqithisa kwe-matrix yokutshintsha yi-24 Gbit / s. Isantya sokuhanjiswa kwepakethi - 17.8 mpps. Kukho itafile ye-MAC yeedilesi ezingama-8000. nge-9 kB kwandisa ukusebenza xa uhambisa iipakethi ezinkulu zedatha.
Ixhasa ulawulo nge-GUI yewebhu, i-interface yomgca womyalelo (i-multi-level CLI), i-SSH, i-SNMP, i-telnet, i-console.
