Ekusebenzeni kwami, ukunika amandla idivayisi nokuthola isithombe kuyo ebangeni elide ukusuka ekushintsheni kuvele akuwona umsebenzi olula. Ikakhulukazi lapho amanethiwekhi enwebeka esuka ocezu olulodwa lwensimbi aye kumakhamera amaningana ezindaweni ezihlukene.
Noma iyiphi idivayisi eyinkimbinkimbi kakhulu noma engaphansi iqina ngezikhathi ezithile. Ezinye izinto azivamile, kanti ezinye zivamile, futhi lokhu kuyinkolelo-mbono. Ngokuvamile lokhu kuyaxazululwa... kulungile... ngalokhu:
Futhi uma zingekho izandla ezidingekayo ngakolunye uhlangothi lweshubhu, kuzodingeka uphakamise isinqe sakho esihlalweni futhi uhambe / ukushayela / ukundizela kudivayisi.
Akujabulisi ikakhulukazi uma le divayisi isendaweni ethile ngaphansi kophahla noma esigxotsheni... noma ehhovisi elikude.
Ukonga kuyisishayo esikhulu sokuphatha kude. Ngezinye izikhathi i-nasalnik ithola ikhamera / i-switch/router ku-Aliexpress futhi ichaza ukuthi kungani le ngxenye yehadiwe ibiza ama-ruble angu-700, kuyilapho leyo oyinikezayo ngaphezu kwe-5k ingaba umsebenzi ongenakwenzeka. Ikakhulukazi uma le divayisi isivele itholakala futhi abantu beza kuwe ngesisekelo sokuthi "kungani ingasebenzi kithi?" Iklayenti lihlale lilungile, ikakhulukazi uma lifona kancane ngangokunokwenzeka. Futhi lokhu kusho ukuthi le divayisi engalungile yaseShayina ye-f ***ing kumele ibe nohlobo oluthile lokuzimela futhi kuhle ukuthi "ukhahlele" ngokuzenzakalelayo ngisho nangaphambi kokuba iklayenti likubone.
Amaswishi e-PoE aphethwe alungele ukusindisa isimo; ngenhlanhla, ethulwa ngobuningi emakethe.
Futhi nansi inombolo yenkinga yokuQala: ngubani, noma kunalokho, kunokuqapha, ukuze uma idivayisi "ebambekile", iphushe umyalo wokusetha kabusha amandla kumbobo yokushintsha ye-PoE. Ukuphakamisa nokusetha iseva kudinga ukunyakaza komzimba okwengeziwe kanye nehadiwe.
Ake sithi endaweni yami: kukhona amakhamera wevidiyo ayi-15 kuphela, irekhoda yevidiyo futhi ... yilokho kuphela. Ngesikhathi esifanayo, i-7 itholakala ebangeni elingaphansi kwe-100 m, enye i-5 ukuya ku-150, kanti enye i-3 ibanga lamamitha angu-200. Kudingeka ukwenza ingqalasizinda ibe lula ukuze abantu beze kule sayithi kuphela. izinjongo zokuvimbela.
Isixazululo silula kakhulu - yiba ne-PoE switch ekwazi ukuqapha amakhamera futhi isethe kabusha amandla echwebeni, futhi "ifinyelele" ngekhebula ebangeni elingamamitha angama-200+.
Mikrotik
Ukuba nezitifiketi ezimbili (i-MTCNA ne-MTCRE), amehlo ami aqala ukuwela ku-Mikrotik. Lo mkhiqizi unokukhethwa okuncane kwamamodeli anenkomba ye-P, isibonelo,
I-IMHO, isethi encane kakhulu yezilungiselelo. Kwenzekani uma ikhamera ilahleka futhi igeje ama-ping ambalwa? - qala kabusha!
Kuthiwani uma ikhamera isanda kufa? I-Mikrotik izoyinqamula njalo ngomzuzu? ..
Emsebenzini wami, kwakukhona inani elikhulu lamaphutha kugesi we-CCR. Liyini iphuzu lokushintshwa kwe-PoE uma kunengozi enkulu yokuphelelwa amandla ezinyangeni eziyisithupha?..
Ngaphezu kwalokho, angizange ngithole ulwazi lokuthi iMikrotik ingasebenza ngezintambo okungenani amamitha angu-150+ ubude...
I-Zyxel
Ngenkathi ngifunda abameleli babathengisi abaqhudelanayo, ngathola . Shintsha kusukela kuchungechunge lwe-Zyxel GS1350. Kubiza kakhulu kune-Mikrotik, kodwa angizange ngiqaphele izinkinga nge-Zyxel ngezinsiza zamandla "ezibuthakathaka".
I-Zuksel ibeka amaswishi e-GS1350 njengoba edalelwe amasistimu okuqapha amavidiyo. Amaswishi athola ukuthi ikhamera "ibambekile" futhi ayiqalise kabusha ngokusebenzisa amandla.
Indlela yokuthola ukuthi umile
Ngaphambi kokuthi ngiqale ukujwayelana nale divayisi, ngicabange ukuthi iswishi ihlaziya uhlobo lwethrafikhi futhi ngokushesha nje lapho ukusakazwa kwevidiyo kuphela, inkinobho kusetha kabusha amandla...
Kodwa konke kwavela kwaba lula kakhulu.
"Auto PD Recovery" ingasebenza ngezindlela ezimbili:
- I-LLDP, okungukuthi, idivayisi ngokwayo inikeza ulwazi olumayelana nayo, uma, ngokuqinisekile, idivayisi iyisekela. Impendulo ye-LLDP yeza, okusho ukuthi ingxenye yehadiwe βiyaphilaβ. Uma ingekho impendulo, "sinqamula" amandla ngenkani bese silinda impendulo.
- I-Ping. Kukuphi lapho kulula khona? I-Pinging - Ayikho impendulo - Iqalisa kabusha!
Inombolo yama-ping ngaphandle kwempendulo, isikhathi sokusetha kabusha kanye nenani lokusetha kabusha amandla kuyalungiseka. Okunengqondo impela, ngoba akukho phuzu βekukhahleleniβ ucezu lwehadiwe uma lungaqali okwesithathu.
Kodwa angiqondi: kuyini okukhethekile kumakhamera wevidiyo LAPHA?
Ngale ndlela ungakwazi ukuqapha noma iyiphi idivayisi yenethiwekhi. Ngisho neyodwa engayisekeli i-PoE.
Si-oda igajethi enjalo ku-Aliexpress futhi noma iyiphi idivayisi yenethiwekhi iphenduka i-PoE.
Uma igajethi iba yiqhwa, iswishi izosetha kabusha amandla embobeni futhi kulogi sizobona into efana nale:
233 Sep 07 17:24:41 DE interface: Port 4 - ReoLink link up 100M/F

241 Sep 07 17:24:01 WA interface: Port 4 - ReoLink PD failure is detected and reboot due to Auto PD Recovery (ping mode)Ubude bekhebula obukhulu.
Ekhasini wathi:
Ukusetshenziswa kwemodi yobubanzi obunwetshiwe kulawa maswishi kukuvumela ukuthi ukhuphule ibanga eliphakeme kumadivayisi anikwe amandla ukuya kumamitha angama-250.
Sijwayele ukungabaza nganoma iyiphi incwajana yokukhangisa.
Ngabopha amachopho amabili echweba elisha (amamitha angu-305) futhi nganamathisela eyodwa ekhamera enye emshinini. Ikhamera ayizange isuke... Kubonakala sengathi kulindelekile ^_^
Ngahlala, nganwaya ithanga, ngangena kumasethingi, ngabheka ibhokisi elithi βUbubanzi obunwetshiwe", futhi... imizuzwana eyishumi yokuthula - i-drum roll... ikhamera yaqala ukusebenza! Ku-305 MTERS!
Akukho ukulahleka kwephakethe!
Ngakho-ke, ukushintshwa kochungechunge lwe-GS1350 akufinyeleli ku-250 okumenyezelwe, kodwa okungamamitha angama-305!
Yiqiniso, mhlawumbe ukukopela kubuye kube sezingeni lekhebula:
Uma ubude obuningi budingeka, ungaxhuma izingxenye ezimbalwa zekhebula ngokusebenzisa uhlobo oluthile lokuphinda. Ungakwazi futhi ukuxhuma enye inkinobho ye-poe ekugcineni ukuze uxhume amadivaysi amaningana.
Isibonelo, nge-UPVEL UP-215SGE (Angikabheki ukuthi ithembeke kangakanani. Ngisanda kuyibona.) Yona ngokwayo inikwa amandla nge-PoE futhi inika amandla amadivayisi nge-PoE.
Kodwa lesi yisihloko esihlukile semibandela ethile, njengoba sidinga ukuklama kucabangela zonke izici.
Uma inketho "Yobubanzi Obunwetshiwe" inikwe amandla, imbobo izofaka ngokuzenzakalelayo iphrothokholi engu-802.3at futhi isethe isabelomali samandla ku-33W.
Kodwa kufanelekile ukubeka izinto eziza kuqala uma kwenzeka bonke abathengi beqala ukudla ngenkuthalo ... Amachweba anokubaluleka okuphansi, uma kwenzeka ukuntuleka kwamandla ekushintsheni, azothola amandla aceliwe ekugcineni.
Ukuvikelwa kombani
Inkinga yesibili lapho ubeka amadivayisi ngaphandle ukuvikela ekukhuphukeni kwamandla.
Inani le-ESD/Surge Protection:
I-ESD β 15 kV / 8 kV (Umoya/Othintana naye);
Surge β 4 kV (Ethernet Port).Qaphela. I-ESD - ukuvikelwa kwe-electrostatic voltage, Surge -
ukuvikelwa kwe-overvoltage. Uma ukukhishwa okumile kwenzeka emoyeni kuze kufike ku-15
i-kilovolt, noma ama-electrostatics angu-8 kV lapho usondelene, noma ukuhlinzwa kwesikhashana
ama-voltage afinyelela ku-4 kilovolts - inkinobho inethuba elihle lokusinda kuleyo ndlela
izinkinga.
Hhayi-ke, kukhona endaweni ethile ecaleni lokunamathisela isisekelo.
Ngethemba ukuthi akumele ngihlole lokhu ^_^
I-PoE eqhubekayo
Inikeza amandla ngisho noma idivayisi ingasabeli. Ngokuzenzakalelayo le nketho inikwe amandla. Ungakhohlwa ukuhlola le nketho ngaphambi kokubuyekeza i-firmware kumakhamera akho. Uma kungenjalo kungase kungabi mnandi...
UCisco uthanda i-CLI
Kubathandi be-console, kanye nokwenza ngokuzenzakalelayo ukusetha, ungasebenzisa i-CLI yesitayela se-Cisco ejwayelekile.
Uma ungasebenzisi, isibonelo, i-telnet/snmp namanye amaphrothokholi, ngincoma ukuthi uwavale ukuze ukhuphule ukuphepha kwedivayisi.
Hhayi ngaphandle kwempukane emafutheni...
Iswishi inento yemenyu ethi βCloud Managementβ
Kodwa uma sizama ukubhalisa siyakuthola lokhu
Okwamanje usekelo lwalawa madivayisi lukhona akukanikwa amandla. Umkhiqizi uthembisa ukuwengeza ngo-2020. Ngesikhathi esifanayo, ngeke udinge ukuvuselela i-firmware yokushintsha!
isiphetho
I-Zyxel GS1350 kuze kube manje ukuphela kwendlela eyenelisa izicelo zami:
- iphethwe ngesethi ejwayelekile yokusebenza
- ubude bekhebula 200+ amamitha ngaphandle kwamalunga
- ukuqapha kanye nokuqalisa kabusha abathengi be-PoE
- ubulula kanye nokuguquguquka kokucushwa.
Mhlawumbe kunezinye izixazululo emakethe ezizohlangabezana nezidingo zami, kodwa angikazitholi okwamanje.
Ngimema labo abafuna ukuxoxa ngesihloko kuTelegram ezingxoxweni engizidalile:
1. - Ingxoxo enesihloko kuZyxel
2. - Ingxoxo enesihloko kuMikrotik
