Nigute inshinge za PoE zikora?

Iyo uhinduranya cyangwa ibindi bikoresho bidafite ibikorwa byo gutanga amashanyarazi bihujwe nibikoresho bikoreshwa (nka kamera ya IP, APs idafite insinga, nibindi), amashanyarazi ya PoE arashobora gutanga ingufu nogukwirakwiza amakuru kubikoresho bikoresha icyarimwe, hamwe no kohereza intera igera kuri metero 100. Muri rusange, amashanyarazi ya PoE abanza guhindura ingufu za AC mumashanyarazi ya DC, hanyuma agatanga ingufu kubikoresho bito bya PoE bito.

Nigute ushobora gukoresha inshinge za PoE?

Muri iki gice, dukoresha cyane cyane kamera ya IP ikoreshwa na PoE (cyangwa ibindi bikoresho bya terefone ya PoE) nkurugero rwo gusobanura uburyo bwo gukoresha amashanyarazi ya PoE hamwe na moteri itari PoE kugirango itange amashanyarazi. Ibikoresho bigomba gutegurwa ni: kamera nyinshi za IP, ibikoresho byinshi bya ingufu za PoE (umubare ugomba kugenwa ukurikije umubare wa kamera ya IP), icyuma gisanzwe kitari PoE hamwe ninsinga nyinshi (Cat5eCat6Cat6a).
1. Banza ugerageze ibikoresho byose kugirango umenye neza ko kamera ya IP, amashanyarazi ya PoE hamwe na sisitemu yo gucunga kamera byose bikora mubisanzwe. Mbere yo kwinjizamo kamera, uzuza ibice byurusobe bijyanye na kamera mbere.
2. Intambwe yambere irangiye, koresha umugozi wumuyoboro kugirango uhuze kamera nicyambu cyamashanyarazi cya PoE itanga amashanyarazi.
3. Ibikurikira, shyira kamera ahantu hacanye neza kugirango ishusho yafashwe na kamera isobanuke.
4. Koresha urundi rugomero kugirango uhuze amakuru yohereza amakuru ya switch na amashanyarazi.
5. Hanyuma, shyira umugozi wamashanyarazi mumashanyarazi hafi ya AC.

Ni ibihe bintu bigomba kwitabwaho mugihe ugura inshinge ya PoE?

* Umubare wibikoresho bikoresha ingufu: Niba hari igikoresho kimwe gusa gifite ingufu, icyambu kimwe PoE itanga amashanyarazi irahagije. Niba hari ibikoresho byinshi bya PoE byanyuma, ugomba kwemeza ko umubare wibyambu bya PoE winjiza ibyambu bihuye.
* PoE ingero imwe yo gutanga amashanyarazi: Birakenewe kwemeza ko amashanyarazi hamwe nigikoresho cyo kwakira amashanyarazi bihujwe byujuje ubuziranenge bwa PoE. Mubisanzwe hariho ibipimo bitatu bitanga amashanyarazi: 802.3af (PoE), 802.3at (PoE +), na 802.3bt (PoE ++). Ingano ntarengwa yo gutanga amashanyarazi ni 15.4W, 30W, na 60W / 100W.
* Umuyagankuba w'amashanyarazi: Menya neza ko imbaraga z'umuriro w'amashanyarazi hamwe nibikoresho bifata amashanyarazi bihuye. Kurugero, kamera nyinshi zo kugenzura zikora kuri 12V cyangwa 24V. Kuri iyi ngingo, ugomba kwitondera kugirango umenye neza niba amashanyarazi atangwa n’amashanyarazi ya PoE ahura n’agaciro ka voltage ikora ya kamera kugirango wirinde umuvuduko ukabije cyangwa kunanirwa gukora.

Ibibazo byatewe inshinge:

Ikibazo: Ese amashanyarazi ya PoE ashobora gutanga amashanyarazi kuri gigabit?
Igisubizo: Oya, keretse niba gigabit ihinduka ifite icyambu cya PoE.

Ikibazo: Ese amashanyarazi ya PoE afite icyambu cyo kugenzura?
Igisubizo: Oya, amashanyarazi ya PoE arashobora gutanga amashanyarazi kubikoresho bikoreshwa na PoE binyuze mumashanyarazi, gucomeka no gukina. Mubyongeyeho, ifite kandi ibikorwa bigufi byo kurinda imiyoboro ngufi, ishobora gutanga mu buryo butaziguye ibikoresho bidafite insinga n'ibikoresho byo gukurikirana. Niba ukeneye ibikoresho bitanga amashanyarazi PoE hamwe nibikorwa byo kuyobora, urashobora guhitamo icyerekezo cya PoE.
