🥇PoE i te tawhiti o te 200+ mita. Te aroturuki me te tīmata anō aunoa i ngā kiritaki PoE

E ai ki aku wheako, ehara i te mea ngāwari te whakakā i tētahi taputapu me te whiwhi pikitia mai i taua taputapu i tawhiti atu i te pana. He pono rawa tēnei ina toro atu tētahi taputapu kotahi ki ngā kāmera maha i ngā tawhiti rerekē.

Ahakoa te iti o te uaua o tētahi taputapu, ka tūpato i ētahi wā. Ko ētahi he iti ake te auau, ko ētahi he auau ake, ā, koinā te whakapono. I te nuinga o te wā, ka whakatauhia tēnei... he tika... mā tēnei:

Ā, ki te kore he ringa e tika ana i tērā taha o te ngongo, me tango e koe tō papa i te tūru ka hikoi/taraiwa/rere ki te taputapu.

He tino hoha mēnā kei raro i te tuanui tēnei taputapu, kei runga rānei i tētahi pou... kei roto rānei i tētahi tari mamao.

Ko te penapena moni te mate nui o te whakahaere mamao. I ētahi wā ka kitea e te rangatira he kāmera/pana/pouara i runga i te AliExpress, ā, he mahi uaua te whakamārama he aha te utu o tēnei taputapu i te 700 rubles i te mea e tukuna ana e koe mō te neke atu i te 5. Ina koa mēnā kei roto i te taonga te taputapu, ā, ka pātai mai rātou, "He aha te kore e mahi mā mātou?" He tika tonu te kiritaki, ina koa ka waea mai rātou i ngā wā katoa. Ko te tikanga o tēnei me whai mana motuhake tēnei mea Hainamana, ā, me "whana" aunoa i mua i te kitenga o te kiritaki.

Kua rite ngā pana PoE whakahaeretia ki te whakaora i te āhuatanga, he waimarie, he nui te maha o rātou kei te mākete.

Ā, koinei te raruraru tuatahi: ko wai, ko wai rānei, ka aroturuki kia taea ai te tuku i tētahi whakahau tautuhi hiko ki te tauranga pana PoE mēnā ka mau te taputapu. Me nui ake te kaha me te taputapu hei whakarite me te whirihora i tētahi tūmau.

Me kī, he wāhi kei ahau me ngā kāmera ataata 15, he kāmera papaaho, ā... koinā katoa. E whitu o aua wāhi kei raro iho i te 100 mita te tawhiti, e rima kei te 150 mita te tawhiti, ā, e toru kei te 200 mita te tawhiti. Me whakangawari ake e au te hanganga kia kore ai e hiahiatia he tirotiro i te wāhi mō ngā mahi tiaki anake.

He tino māmā te otinga – he pana PoE ka taea te aroturuki i ngā kāmera me te tautuhi anō i te hiko i te tauranga, ā, ka "tae atu" hoki mā te taura mō te tawhiti o te 200+ mita. "kāore he okiokinga kotahi."

Mikrotik

I te mea e rua ngā tiwhikete (MTCNA me MTCRE), ko Mikrotik taku whiringa tuatahi. He iti noa ngā tauira P-suffix a tēnei kaihanga, hei tauira, tēnei.

Ki tōku whakaaro, he iti rawa te whānuitanga o ngā tautuhinga. He aha te mea ka tupu mēnā ka mau te kāmera, ā, ka ngaro ētahi ping? Tīmata anō!

A, ki te mate noa te kāmera? Ka whakawetohia e Mikrotik i ia meneti?

E ai ki aku wheako, he nui ngā pūnaha hiko hapa o te CCR. He aha te painga o te pana PoE mēnā he nui te tūponotanga ka pakaru nā te pakaru o te pūnaha hiko i roto i ngā marama e ono?

Heoi anō, kāore au i kite i tētahi kōrero e whakaatu ana ka taea e Mikrotik te mahi me ngā waea roa atu i te 150+ mita…

zyxel

I a au e ako ana i ngā māngai o ngā kaihoko whakataetae, ka tūtaki ahau ki HabréNō te raupapa Zyxel GS1350 te pana. He nui ake te utu i te Mikrotik, engari kāore anō kia tūtaki ahau ki tētahi raruraru me ngā pūtake hiko ngoikore o te Zyxel.

E hokohoko ana a Zuksel i ngā pana GS1350 he mea hanga motuhake mō ngā pūnaha tirotiro ataata. Ka kitea e ngā pana ina mau te kāmera, ā, ka whakaara anō mā te hiko.

Tikanga mō te kite i te hukapapa

I mua i taku tīmatanga ki te mōhio ki tēnei taputapu, i whakaaro ahau ka tātarihia e te pana te momo waka, ā, ina mutu te rere o te ataata, ka tautuhi anō te pana i te hiko...
Engari he tino māmā ake ngā mea katoa.

Whakaora PD Aunoa ka taea te mahi i roto i ngā aratau e rua:

LLDP, ko te tikanga ka whakaratohia e te taputapu tonu ngā mōhiohio mōna anō, mēnā e tautokona ana e ia. Kua tae mai he urupare LLDP, ko te tikanga kei te ora te taputapu. Ki te kore he urupare, ka tapahia e mātou te hiko ka tatari mō te urupare.
PingHe aha atu te mea māmā ake? Ping – Kāore he whakautu – Tīmata anō!

Ka taea te whirihora i te maha o ngā ping kāore anō kia whakautua, te wā tautuhi anō, me ngā tautuhi anō hiko. He tika tēnei, nā te mea kāore he painga o te whana i tētahi taputapu mēnā kāore e tīmata i te tuatoru o ngā whakamātautau.

Ko te mea anake kāore au i te mārama ko: he aha te tohungatanga o KŌNEI i roto i ngā kāmera ataata?
Ka taea te whakamahi i tēnei tikanga hei aroturuki i tētahi taputapu whatunga, tae atu ki ngā mea kāore e tautoko ana i te PoE.

Ka tono mātou i tēnei taputapu mai i AliExpress, ā, ka huri tetahi taputapu whatunga hei PoE.

Ki te tūpato te pūrere, ka tautuhi anō te pana i te hiko ki te tauranga, ā, ka kite tātou i tētahi mea pēnei i roto i ngā rangitaki:

233 Sep 07 17:24:41 DE interface: Port 4 - ReoLink link up 100M/F
 234 Sep 07 17:24:39 DE interface: Port 4 - ReoLink link down
 235 Sep 07 17:24:32 DE interface: Port 4 - ReoLink link up 100M/F
 236 Sep 07 17:24:30 DE interface: Port 4 - ReoLink link down
 237 Sep 07 17:24:26 NO system: PethPse Port 4 - ReoLink OnOff Trap, Port Detection Status is Delivering Power
 238 Sep 07 17:24:24 DE interface: Port 4 - ReoLink link up 100M/F
 239 Sep 07 17:24:04 NO system: PethPse Port 4 - ReoLink OnOff Trap, Port Detection Status is Disabled
 240 Sep 07 17:24:02 DE interface: Port 4 - ReoLink link down
 241 Sep 07 17:24:01 WA interface: Port 4 - ReoLink PD failure is detected and reboot due to Auto PD Recovery (ping mode)

Te roa mōrahi o te taura.

Kei te whaarangi zyxel e kīia ana:

Mā te whakamahinga o te Aratau Awhe Whānui i roto i ēnei pana ka taea te whakanui ake i te tawhiti mōrahi ki ngā taputapu hiko ki te 250 mita.

Kua taunga mātou ki te whakahē i tētahi pukapuka pānuitanga.

I whakapikohia e au ngā pito e rua o tētahi koiri hou (305 mita) ā, i monohia tētahi ki te kāmera, tētahi ki te pana. Kāore te kāmera i tere... Me te mea i tumanakohia ^_^

I noho ahau i reira, i rakuraku i tōku mahunga, ka haere ki ngā tautuhinga, ka tohua te pouaka "Te awhe roa", ā... tekau hēkona o te wā puku – te tangi o te pahu... ka tīmata te kāmera ki te mahi! I te 305 MITA!

Kāore he ngaronga mōkihi!

Nō reira, kāore te pana raupapa GS1350 i eke ki te 250 mita i whakaritea, engari ki te 305 mita nui!

He pono, tera pea ko te tinihanga kei roto i te kounga o te taura:
E tata ana ki te 12 rubles te utu mō te Rexant FTP Cat.6.

Mena e hiahiatia ana he roa ake, ka taea te hono i ētahi wāhanga taura mā te whakamahi i tētahi pūwhakahou. Ka taea hoki te hono i tētahi atu pana PoE ki te pito hei hono i ngā taputapu maha.

Hei tauira, mā te UPVEL UP-215SGE (Kāore anō kia whakamātauria e au tōna pono. I tūpono noa ahau ki tētahi.) Ka whakakahangia e te PoE tonu, ā, mā te PoE ka whakakaha i ngā taputapu.

Engari he kaupapa motuhake tēnei mō ngā āhuatanga motuhake, nā te mea me whai hoahoa e whai whakaaro ana ki ngā āhuatanga katoa.

Ina whakahohea e koe te kōwhiringa "Awhe whānui", ka tautuhi aunoa te tauranga i te kawa 802.3at, ā, ka whakatakoto i te tahua hiko ki te 33W.

Engari he mea tika kia whakatakotohia ngā kaupapa matua mēnā ka tīmata ngā kaihoko katoa ki te whakamahi kaha i te hiko... Ko ngā tauranga iti-kaupapa matua, mēnā he korenga hiko i runga i te pana, ka whiwhi whakamutunga i te hiko e tonoa ana.

Te ārai i te uira

Ko te tuarua o ngā take ina whakatakotohia ngā taputapu ki waho ko te tiaki i a rātou mai i ngā ngaru hiko.

ESD/Te Uara Parenga Ngaru:
ESD – 15 kV / 8 kV (Air/Contact);
Huringa – 4 kV (Tauranga Ethernet).
Tuhipoka: ESD – Te Parenga Tukunga Hiko-pūmau, Te Ngaru –
parenga ngaohiko. Mēnā ka puta te rere i te rangi ki te 15
kirovolt, 8 kV electrostatics ranei i te whakapiri tata, te ngaru rangitahi ranei
ngaohiko tae atu ki te 4 kilovolts - he pai te tupono o te whakawhiti ki te ora penei
raruraru.

Āe, he wāhi anō kei te tinana hei tāpiri i te whenua.
Ko tāku tumanako kāore au e hiahia ki te tirotiro i tēnei ^_^

PoE Tonu

Ka whakarato hiko ahakoa kāore te pūrere e aro mai. Ka whakahohea tēnei kōwhiringa mā te taunoa. Kia mahara ki te tirotiro i tēnei kōwhiringa i mua i te whakahōu i te pūmanawa kāmera. Ki te kore, ka raru pea...

CLI rite ki a Cisco

Mō te hunga e aroha ana ki ngā papatohu, me te whirihoranga aunoa anō hoki, ka taea e koe te whakamahi i te CLI kāhua-Cisco kua mōhiotia.

Ki te kore koe e whakamahi, hei tauira, i te telnet/snmp me ētahi atu tikanga, ka tūtohu ahau kia whakakorehia aua tikanga hei whakanui ake i te haumarutanga o te pūrere.

Kāore i te kore he namu i roto i te hinu kakara...

Kei te pana he tūemi tahua e kiia nei ko "Whakahaere Kapua".

Engari ina ngana mātou ki te rēhita ka puta mai tēnei

I tēnei wā, kei te wātea te tautoko mō ēnei taputapu nebula Kāore anō kia whakahohea. E oati ana te kaihanga ka tāpirihia rātou i te tau 2020. Kāore koe e hiahia ki te whakahou i te pūmanawa o te pana!
