Mumunda wekutarisa kuchengetedza, akawanda maturusi etiweki ari kushandiswa anotsigira PoE magetsi ekupa. Mune network monitoring yekuvaka, kuitira kudzikisa wiring mutengo uye kuita kuti zvive nyore uye nekukurumidza, mazhinji einjiniya makambani achafunga kushandisa PoE magetsi ekupa, ndiko kuti, kushandisa PoE switch kune magetsi ekuongorora makamera. Saka, mangani maturusi anogona PoE indasitiri switch yekugovera simba?

1. PoE chinja simba rekupa mwero

Kuti uone kuti mangani makamera anogona kufambiswa nePoE switch panguva imwe chete, zvinhu zviviri zvinofanirwa kutariswa: chiyero chemagetsi chePoE switch uye huwandu hwemagetsi eiyo PoE switch. Iyo magetsi eiyo PoE switch inogona kunzwisiswa seye-imwe-chiteshi magetsi eiyo PoE switch. Pane zviyero zviviri zvePoE switch dzine mukurumbira pamusika, IEEE802.3af uye IEEE802.3at. Iyo IEEE802.3af chiyero inotsanangura magetsi e15.4W, uye IEEE802.3at chiyero inotsanangura magetsi anosvika makumi matatu. Nekuda kwemaitiro akasiyana ekupa magetsi, iyo single-port magetsi emagetsi akasiyana zvakare. Semuenzaniso, simba rekamera i9W, uye af standard PoE switch inogona kushandiswa; Kana simba rekamera riri 20W, unofanirwa kushandisa af standard PoE switch; kana simba rekamera richipfuura 30W, unofanirwa kushandisa yakatsaurirwa PoE magetsi emagetsi module kupa simba.

Kazhinji kutaura, switch yePoE inotsigira ese af uye pamagetsi emagetsi zviyero ine inozvigadzirisa yega magetsi. Semuenzaniso, kana yakabatana kune 5W mudziyo, inopa 5W yesimba; kana yakabatana kune 20W mudziyo, ipapo inopa 20W yesimba.

2. Simba rose remaindasitiri ePoE switches

Iyo yakazara simba reindasitiri yePoE switch chiratidzo chakakosha, chakanangana nekuti mangani makamera anogona kuunzwa. Kutora 24-port PoE switch ine magetsi e400W, iyo yakazara simba rePoE switch rinenge 370W mushure mekubvisa kurasikirwa.

Pasi peIEEE802.3af standard, inogona kupa 24 ports (370 / 15.4 = 24), kureva kuti, inogona kupa simba kumakamera makumi maviri nemana panguva imwe chete, kureva, simba rakazara. Asi kana ikaverengerwa maererano neIEEE802.3at chiyero cheimwe-chiteshi chepamusoro simba rekupa 30W, panguva imwe chete, inogona chete kupa simba kumachiteshi gumi nemaviri zvakanyanya (370/30=12).

Mukushandiswa chaiko, iyo yakanyanya simba yekushandisa kweakawanda akajairwa webcams yakaderera, isingapfuuri 15W. Kana chiteshi chega chega chePoE chichichengeta simba zvichienderana nehukuru hwesimba (semuenzaniso, 30W) panguva ino, mamwe madoko achashandisa PoE simba. Zvisingaperi, asi mamwe madoko haakwanise kugovera simba. Semuenzaniso, mamwe maPoE switch anotsigira simba rekugovera simba, iro rinogona kudzivirira mamiriro ezvinhu aya. Paunenge uchitenga PoE switch, zvinoenderana nekuti switch inotsigira simba rekugovanisa simba, kuitira kuti chiteshi chega chega chinongogovera simba rinoshandiswa, kuitira kuti magetsi ePoE switch agone kushandiswa zvakanyanya.

3. Kugovana ruzivo rwekushandisa PoE indasitiri switch

a. Iko kushandiswa kwekuchinja kunotsigira simba rekugovera simba kunogona kuwedzera simba rekupa magetsi;
b. Kutanga nzwisisa huwandu hwesimba rekushandisa kweiyo powered mudziyo, uye wogovanisa iyo yakazara magetsi eiyo PoE switch neyakakura mashandisiro emagetsi kuti uwane maturusi mangani anogona kupihwa nePoE switch.
