一.Iyo PoE switch ndiyo hombe iri nani?
Sezvo paine akawanda emagetsi epamusoro-soro mumidziyo yekutarisa yazvino, vanogadzira switch vanowanzogadzira PoE switch ine simba repamusoro. Nekudaro, zvigadzirwa zvakawanda pamusika zvinongotevera kupihwa kwesimba rakazara, uye usatarise huwandu hwezviteshi. Kana simba rawedzerwa, mutengo wakazara wemidziyo uchawedzerawo, saka mutengo wekutenga unozowedzera. Naizvozvo, kana vashandisi vachitenga, ivo vanofanirwa kusarudza switch yakakodzera zvinoenderana nemamiriro chaiwo, kwete iyo yakakwirira simba, zviri nani.
二.Ndedzipi njodzi dzePoE panguva yekugadzira magetsi?
1. Simba risina kukwana
820.af yakajairwa PoE inobuda simba isingasviki 15.4w, iyo yakakwana kune general IPC, asi kune yakakwirira-simba PD, iyo inobuda simba haigone kuita zvinodiwa;
2. Ngozi yakanyanya kunyanya
Kazhinji kutaura, switch yePoE ichapa simba kune akawanda epamberi-ekupedzisira IPCs panguva imwe chete. Kana iyo magetsi emagetsi module yekuchinja ikatadza, ichakanganisa basa remakamera ese, uye njodzi yacho yakanyatso kunyura;
3. Zvigadzirwa zvepamusoro uye mari yekugadzirisa
Kuenzaniswa nedzimwe nzira dzekupa magetsi, PoE magetsi ekupa tekinoroji ichawedzera mushure mekutengesa kugadzirisa basa. Kubva pakuona kwekuchengetedza, kugadzikana kwesimba rimwe chete ndiro rakanakisisa.
三.Ndeipi nzvimbo yakachengeteka yekufambisa yePoE magetsi?
Iyo yakachengeteka yekufambisa chinhambwe chePOE simba rekupa 100 metres, uye zvinokurudzirwa kushandisa iyo yepamusoro shanu yakazara yemhangura network tambo. Yazvino yazvino inogona kufambiswa kure kure neakajairwa Ethernet tambo, saka nei kureba kwekufambisa kuchigumira kumamita zana? Icho chokwadi ndechekuti kureba kwekufambisa kure kwePoE switch kunonyanya kuenderana nedanho rekufambisa data. Kana kureba kwekufambisa kuchipfuura 100 metres, kunonoka kwedata uye kurasikirwa kwepaketi kunogona kuitika. Naizvozvo, mukuita chaiko kwekuvaka, kureba kwekufambisa hakufanirwe kudarika 100 metres. Nekudaro, kwatova nemamwe maPoE switch anogona kusvika kureba kwekutapurirana kwemamita mazana maviri nemakumi mashanu, iyo inokwana kune kureba kwemagetsi magetsi. Zvinotendwa zvakare kuti nekuvandudzwa kwePoE magetsi ekugadzira tekinoroji munguva pfupi iri kutevera, kureba kwekufambisa kuchawedzerwa kure.
四.Ini ndinofanira kutenga yakajairwa PoE switch? Zvisiri-standard zvinogona kushandiswa here?
Sarudza yakajairwa kana isiri-yakajairwa, izvi zvinonyanya zvinoenderana neiyo magetsi AP, IP
Ndeapi voltage anotsigira Kamera? 48, 24, 12v. Kana iri 48v, iwe unofanirwa kusarudza yakajairwa PoE switch; kana iri 24 kana 12v, iwe unofanirwa kutsvaga inoenderana isina-standard switch, hongu, iyo yakajairwa inogonekawo, asi kana ukatenga yakajairwa, iwe unofanirwa kuve wakashongedzerwa nePD splitter.
Kubva pane tsananguro, tinogona kuona kuti dzimwe nguva dzisiri-yakajairwa switch dziripowo, uye mutengo unenge wakadzikira, asi isu tichiri kukuyeuchidza kuti utenge akajairika switch. Nemhaka yokuti iyo isiri-standard switch haina PoE chip uye haioni chigadziro, zviri nyore kuumba pfupi pfupi kuti upise chigadziro, chinogona kupisa chiteshi pachiedza, kana kukonzera moto mumatambudziko akaoma; nepo chiyero chinja ichaedzwa kana ichiiswa simba kuti isapisa mudziyo.
五.Maitiro ekusarudza PoE switch yekutarisa kuchengetedza uye isina waya yekuvhara?
Kune marudzi akawanda ePoE switches, kubva pa100M kusvika ku1000M, kusvika kugigabit yakazara, pamwe chete nemusiyano pakati pemhando dzisina kutarisirwa uye dzakagadziriswa, uye musiyano muhuwandu hwezviteshi zvakasiyana. Kana iwe uchida kusarudza shanduko yakakodzera, iwe unoda kutarisisa kwakadzama uye kwakadzama. . Tora chirongwa chinoda kutariswa kwepamusoro-tsanangudzo semuenzaniso.
1. Sarudza chiyero chePoE switch
2. Sarudza 100M kana 1000M chinja
Mumhinduro chaiyo, zvinodikanwa kubatanidza huwandu hwemakamera, uye sarudza maparamendi akadai sekugadziriswa kwekamera, bit rate, uye furemu nhamba. Vagadziri vemidziyo yekutarisa vanopa maturusi ehunyanzvi ekuverenga bandwidth, uye vashandisi vanogona kushandisa maturusi kuverenga inodiwa bandwidth uye kusarudza yakakodzera PoE switch.
3. Sarudza af kana pane yakajairwa PoE switch
Sarudza maererano nekutarisa midziyo simba. Semuenzaniso, kana kamera yemhando inozivikanwa yakashandiswa, simba iri 12W max. Muchiitiko ichi, shanduko ye af standard inoda kusarudzwa. Simba repamusoro-tsanangudzo dome kamera i30W max. Muchiitiko ichi, zvinodikanwa kushandisa pa-standard switch.
Chechina, sarudza nhamba yezviteshi pane switch
Zvinoenderana nehuwandu hwezviteshi, PoE switch inogona kukamurwa kuita 4 ports, 8 ports, 16 ports uye 24 ports, nezvimwewo, iyo inogona kunyatsoongorora simba, huwandu, nzvimbo yemidziyo, kushandura magetsi uye kusarudzwa kwemutengo.
