一.Ngaba utshintsho lwe-PoE olukhulu lungcono?
Kuba zininzi izixhobo ezinamandla aphezulu kwizixhobo zangoku zokujonga, abavelisi bokutshintsha bakholisa ukuphuhlisa iiswitshi zePoE ngamandla aphezulu. Nangona kunjalo, iimveliso ezininzi kwiimarike zilandela kuphela ukubonelelwa kwamandla apheleleyo, kwaye ungathatheli ingqalelo inani lamachweba. Xa amandla anyuswa, iindleko zizonke zezixhobo ziya kunyuka, ngoko iindleko zokuthenga ziya kunyuka ngokwendalo. Ngoko ke, xa abasebenzisi bethenga, kufuneka bakhethe ukutshintshela okufanelekileyo ngokweyona meko, kungekhona amandla aphezulu, angcono.
二.Yeyiphi imingcipheko ye-PoE ngexesha lenkqubo yokubonelela ngombane?
1. Amandla angonelanga
I-820.af amandla aphumayo asemgangathweni ye-PoE angaphantsi kwe-15.4w, eyaneleyo kwi-IPC jikelele, kodwa kwi-PD yamandla aphezulu, amandla aphumayo akakwazi ukuhlangabezana neemfuno;
2. Umngcipheko ugxile kakhulu
Ngokuqhelekileyo, i-PoE switch iya kunika amandla kwii-IPC ezininzi zangaphambili ngaxeshanye. Ukuba imodyuli yonikezelo lwamandla yokutshintsha iyasilela, iya kuchaphazela umsebenzi wazo zonke iikhamera, kwaye umngcipheko ugxile kakhulu;
3. Izixhobo eziphezulu kunye neendleko zokugcina
Xa kuthelekiswa nezinye iindlela zobonelelo lwamandla, itekhnoloji yobonelelo lwamandla e-PoE iya kwandisa umsebenzi wokulungisa emva kokuthengisa. Ukusuka kwimbono yokhuseleko, ukuzinza konikezelo lwamandla omnye yeyona nto ingcono.
三.Uthini umgama wothumelo okhuselekileyo wobonelelo lwamandla lwe-PoE?
Umgama wothumelo olukhuselekileyo lonikezelo lwamandla e-POE li-100 leemitha, kwaye kuyacetyiswa ukuba usebenzise intambo yothungelwano yobhedu ezintlanu ezigcweleyo. Umda othe ngqo unokuhanjiswa kude kakhulu ngeentambo ze-Ethernet eziqhelekileyo, kutheni ke ukuba umgama wothumelo ukhawulelwe kwiimitha ezili-100? Inyaniso kukuba umgama ophezulu wothumelo we-PoE switch ngokuyinhloko uxhomekeke kumgama wothumelo lwedatha. Xa umgama wothumelo udlula iimitha ezili-100, ukulibaziseka kwedatha kunye nokulahleka kwepakethi kunokwenzeka. Ngoko ke, kwinkqubo yokwakhiwa kwangempela, umgama wothumelo kufuneka ungabi ngaphezu kweemitha ezili-100. Nangona kunjalo, sele sele kukho utshintsho oluthile lwe-PoE olunokufikelela kumgama wokuhanjiswa kweemitha ezingama-250, ezaneleyo zokunikezelwa kwamandla okude. Kukwakholelwa ukuba ngophuhliso lwetekhnoloji yobonelelo lwamandla e-PoE kungekudala, umgama wothumelo uya kwandiswa kude.
四.Ngaba kufuneka ndithenge iswitshi esemgangathweni ye-PoE? Ngaba ezingezizo ezisemgangathweni zinokusetyenziswa?
Khetha umgangatho okanye non-standard, oku ikakhulu kuxhomekeke umbane AP, IP
Yeyiphi i-voltage exhaswa yikhamera? 48, 24, 12v. Ukuba yi-48v, kufuneka ukhethe i-PoE esemgangathweni yokutshintsha; ukuba i-24 okanye i-12v, kufuneka ufumane inguqu ehambelanayo engekho-standard, ngokuqinisekileyo, umgangatho unakho, kodwa ukuba uthenge umgangatho, kufuneka uxhotyiswe nge-PD splitter.
Ukusuka kwinkcazo, sinokubona ukuba ngamanye amaxesha ukutshintshwa okungaqhelekanga kuyafumaneka, kwaye ixabiso liya kuba liphantsi, kodwa sisakukhumbuza ukuba uthenge utshintsho oluqhelekileyo. Ngenxa yokuba i-switch non-standard ayinayo i-chip ye-PoE kwaye ayiboni isixhobo, kulula ukwenza isiphaluka esifutshane sokutshisa isixhobo, esinokutshisa i-port ekukhanyeni, okanye kubangele umlilo kwimeko enzima; ngelixa iswitshi esemgangathweni iya kuvavanywa xa iqhutywa ukuphepha ukutshisa isixhobo.
五.Unokukhetha njani iswitshi ye-PoE yokubeka iliso kukhuseleko kunye ne-wireless coverage?
Kukho iintlobo ezininzi zokutshintsha kwe-PoE, ukusuka kwi-100M ukuya kwi-1000M, ukuya kwi-gigabit epheleleyo, kunye nokwahlukana phakathi kweentlobo ezingalawulwayo nezilawulwayo, kunye nokwahlukana kwinani lamachweba ahlukeneyo. Ukuba ufuna ukukhetha utshintsho olufanelekileyo, kufuneka uqwalaselwe ngokubanzi kunye nolubanzi. . Thatha iprojekthi efuna ukubeka iliso kwinkcazo ephezulu njengomzekelo.
1. Khetha iswitshi eqhelekileyo yePoE
2. Khetha i-100M okanye i-1000M yokutshintsha
Kwisisombululo sangempela, kuyimfuneko ukudibanisa inani leekhamera, kwaye ukhethe iiparameters ezifana nesisombululo sekhamera, i-bit rate, kunye nenombolo yefreyimu. Abavelisi bezixhobo zokubeka iliso baya kubonelela ngezixhobo zokubala i-bandwidth yobuchwephesha, kwaye abasebenzisi banokusebenzisa izixhobo zokubala umda ofunekayo kwaye ukhethe i-PoE switch efanelekileyo.
3. Khetha i-f okanye kwi-switch ye-PoE eqhelekileyo
Khetha ngokwamandla esixhobo sokubeka iliso. Ngokomzekelo, ukuba ikhamera ye-brand eyaziwayo isetyenzisiweyo, amandla yi-12W max. Kule meko, ukutshintshwa komgangatho we-af kufuneka kukhethwe. Amandla ekhamera yedome enenkcazo ephezulu yi-30W max. Kule meko, kuyimfuneko ukusebenzisa i-switch esemgangathweni.
Okwesine, khetha inani lamazibuko ekutshintsheni
Ngokwenani lamachweba, ukutshintshela kwe-PoE kunokwahlulwa ibe ngamachweba angama-4, amachweba angama-8, amachweba angama-16 kunye namachweba angama-24, njl. njl., Anokuthi abeke iliso ngokubanzi amandla, ubungakanani, indawo yesixhobo, ukutshintsha unikezelo lwamandla kunye nokukhethwa kwexabiso.
