M'zochita zanga, kupatsa mphamvu chipangizocho ndikupeza chithunzi kuchokera patali kwambiri kuchokera pa switch sinakhale ntchito yophweka. Makamaka pamene maukonde amachokera ku chitsulo chimodzi kupita ku makamera angapo pamtunda wosiyana.
Chida chilichonse chovuta kwambiri chimaundana nthawi ndi nthawi. Zinthu zina sizichitika kawirikawiri, ndipo zina sizichitika kawirikawiri, ndipo izi ndi chiphunzitso. Nthawi zambiri izi zimathetsedwa ... ndiko kulondola ... ndi izi:
Ndipo ngati palibe manja ofunikira kumbali ina ya chubu, muyenera kukweza matako anu pampando ndikuyenda / kuyendetsa / kuwulukira ku chipangizocho.
Zimakhala zosasangalatsa makamaka ngati chipangizochi chili penapake pansi pa denga kapena pamtengo ... kapena muofesi yakutali.
Kupulumutsa ndiye mliri waukulu wa kayendetsedwe kakutali. Nthawi zina nasalnik imapeza kamera / switch / rauta pa Aliexpress ndikufotokozera chifukwa chake chida ichi chimawononga ma ruble 700, pomwe chomwe mumapereka kuposa 5k chingakhale ntchito yosatheka. Makamaka ngati chipangizochi chilipo kale ndipo anthu amakufikirani pamaziko akuti "bwanji sichikugwira ntchito kwa ife?" Wothandizira nthawi zonse amakhala wolondola, makamaka pamene akuyimba pang'ono momwe angathere. Ndipo izi zikutanthauza kuti chipangizo choyipa cha China ichi cha f *** ing chiyenera kukhala ndi mtundu wina wodziyimira pawokha ndipo ndikofunikira "kukankha" zokha ngakhale kasitomala asanazindikire.
Ma switch oyendetsedwa a PoE ali okonzeka kupulumutsa zomwe zikuchitika; mwamwayi, amaperekedwa mochulukira pamsika.
Ndipo nayi nambala yavuto Yoyamba: ndi ndani, kapena m'malo, kuposa kuyang'anira, kuti ngati chipangizocho chikakamira, kanikizani lamulo lokhazikitsanso mphamvu pa doko losinthira la PoE. Kukweza ndi kukhazikitsa seva kumafuna mayendedwe owonjezera akuthupi ndi zida.
Tinene pa malo anga: pali makamera a kanema a 15 okha, chojambulira kanema ndi ... ndizomwezo. Panthawi imodzimodziyo, 7 ili pamtunda wosakwana 100 m, wina 5 mpaka 150, ndi wina 3 pamtunda wa mamita 200. M'pofunika kufewetsa zomangamanga kuti anthu athe kubwera kumalo ano okha. zodzitetezera.
Yankho lake ndi losavuta - khalani ndi chosinthira cha PoE chomwe chimatha kuyang'anira makamera ndikukhazikitsanso mphamvu padoko, komanso "kufikira" pa chingwe pamtunda wa 200+ metres.
Mikrotik
Ndili ndi ziphaso ziwiri (MTCNA ndi MTCRE), maso anga adayamba kugwa pa Mikrotik. Wopanga uyu ali ndi mitundu yaying'ono yokhala ndi index ya P, mwachitsanzo,
IMHO, makonda ochepa kwambiri. Kodi chimachitika ndi chiyani ngati kamera itayika ndikuphonya ma ping angapo? - Yambitsaninso!
Nanga bwanji kamera ikangofa? Mikrotik amadula miniti iliyonse? ..
Muzochita zanga, panali zolakwika zambiri pamagetsi a CCR. Kodi kusintha kwa PoE ndi kotani ngati kuli ndi chiopsezo chachikulu chotaya mphamvu m'miyezi isanu ndi umodzi?
Kuphatikiza apo, sindinapeze zambiri zomwe Mikrotik imatha kugwira ntchito ndi mawaya osachepera 150+ mita kutalika ...
zyxel
Ndikuphunzira za oimira ogulitsa opikisana nawo, ndinapeza . Sinthani kuchokera ku Zyxel GS1350 mndandanda. Zimawononga kwambiri kuposa Mikrotik, koma sindinazindikire mavuto aliwonse ndi Zyxel okhala ndi mphamvu "zofooka".
Zuksel imayika masiwichi a GS1350 monga momwe amapangidwira makina owonera makanema. Zosintha zimazindikira kuti kamera yakakamira ndikuyiyambitsanso pogwiritsa ntchito mphamvu.
Njira yodziwira zokakamira
Ndisanayambe kudziwana ndi chipangizochi, ndinaganiza kuti kusinthaku kumasanthula mtundu wa magalimoto ndipo mwamsanga mtsinje wa kanema ukatha, kusinthaku kumapangitsanso mphamvu ...
Koma zonse zidakhala zosavuta.
"Auto PD Recovery" akhoza kugwira ntchito m'njira ziwiri:
- LLDP, ndiko kuti, chipangizocho chimapereka chidziwitso chaumwini, ngati, ndithudi, chipangizocho chimathandizira. Yankho la LLDP lidabwera, zomwe zikutanthauza kuti chidacho ndi "chamoyo". Ngati palibe yankho, timakakamiza "kudula" mphamvu ndikudikirira yankho.
- Ping. Ndikosavuta kuti? Pinging - Palibe kuyankha - Kuyambiranso!
Chiwerengero cha ma pings osayankhidwa, nthawi yobwezeretsanso ndi kuchuluka kwa kukonzanso mphamvu ndizosinthika. Zomwe zili zomveka, chifukwa palibe chifukwa "kukankha" chidutswa cha hardware ngati sichiyamba kachitatu.
Koma sindikumvetsa: luso la makamera a kanema PANO ndi chiyani?
Mwanjira imeneyi mukhoza kuwunika chipangizo chilichonse maukonde. Ngakhale imodzi yomwe siyigwirizana ndi PoE.
Timayitanitsa chida chotere kuchokera ku Aliexpress ndipo chida chilichonse cha netiweki chimasanduka PoE.
Chidacho chikawuma, chosinthiracho chidzakhazikitsanso mphamvu ku doko ndipo muzopika tiwona chonchi:

Patsamba anati:
Kugwiritsiridwa ntchito kwa Extended range mode mumasinthidwe awa kumakupatsani mwayi wowonjezera mtunda wautali kupita ku zida zamagetsi mpaka 250 metres.
Tidazolowera kukayikira kabuku kalikonse kotsatsa malonda.
Ndinadula mbali ziwiri za bay yatsopano (mamita 305) ndikuyika imodzi mu kamera ndi ina mu chosinthira. Kamera sinachoke ... Zikuwoneka kuti zikuyembekezeredwa ^_^
Ndidakhala, ndikukanda dzungu, ndidalowa m'makonzedwe, ndikuyang'ana bokosilo "Zowonjezera", ndi ... masekondi khumi a chete - ng'oma roll ... kamera inayamba kugwira ntchito! Pa 305 MITA!
Palibe kutayika kwa paketi!
Choncho, kusintha kwa mndandanda wa GS1350 sikunafikire 250, koma mamita 305!
Zowona, mwina chinyengo chimakhalanso mumtundu wa chingwe:
Ngati kutalika kokulirapo kumafunika, mutha kulumikiza zigawo zingapo za chingwe kudzera mumtundu wina wobwereza. Mukhozanso kulumikiza lophimba lina poe kumapeto kulumikiza zipangizo zingapo.
Mwachitsanzo, kudzera pa UPVEL UP-215SGE (Sindinayang'ane kuti ndi yodalirika bwanji. Ndangozipeza.) Imayendetsedwa ndi PoE ndi zida zamagetsi kudzera pa PoE.
Koma uwu ndi mutu wosiyana pamikhalidwe inayake, chifukwa umafunika kupanga poganizira zinthu zonse.
Njira ya "Extended range" ikayatsidwa, dokolo liziyika zokha protocol ya 802.3at ndikukhazikitsa bajeti yamagetsi ku 33W.
Koma ndi bwino kuika zinthu zofunika kwambiri ngati ogula onse ayamba kudya mwakhama ... Madoko okhala ndi zofunikira zochepa, pakagwa mphamvu yamagetsi pakusintha, adzalandira mphamvu yofunsidwa komaliza.
Chitetezo champhamvu
Nkhani yachiwiri pakuyika zida panja ndikutetezedwa kumayendedwe amagetsi.
ESD/Surge Protection Value:
ESD β 15 kV / 8 kV (Mpweya/Kulumikizana);
Kuthamanga - 4 kV (Ethernet Port).Zindikirani. ESD - chitetezo chamagetsi a electrostatic, Surge -
chitetezo cha overvoltage. Ngati kutuluka kwa static kumachitika mumlengalenga mpaka 15
kilovolt, kapena 8 kV electrostatics pa kukhudzana kwambiri, kapena opareshoni kwakanthawi
ma voltages mpaka 4 kilovolts - chosinthira chimakhala ndi mwayi wopulumuka
mavuto.
Chabwino, pali penapake pamlandu wolumikizira mazikowo.
Ndikukhulupirira kuti sindiyenera kuyang'ana izi ^_^
Wopitirira PoE
Imapereka mphamvu ngakhale chipangizocho sichikuyankha. Mwachisawawa, njirayi imayatsidwa. Musaiwale kuyang'ana njirayi musanasinthe firmware pamakamera anu. Apo ayi zitha kukhala zosasangalatsa...
Cisco ngati CLI
Kwa okonda ma consoles, komanso kupanga makinawo, mutha kugwiritsa ntchito CLI yodziwika bwino ya Cisco.
Ngati simugwiritsa ntchito, mwachitsanzo, telnet/snmp ndi ma protocol ena, ndiye ndikupangira kuzimitsa kuti muwonjezere chitetezo cha chipangizocho.
Osati popanda ntchentche mumafuta ...
Kusintha kuli ndi menyu "Cloud Management"
Koma tikayesa kulembetsa timapeza izi
Panopa chithandizo chazidazi chayatsidwa osayatsidwa. Wopanga akulonjeza kuti aziwonjezera mu 2020. Nthawi yomweyo, simudzasowa kusintha firmware yosinthira!
Pomaliza
Zyxel GS1350 ndiye chosinthira chokha chomwe chakwaniritsa zopempha zanga:
- imayendetsedwa ndi magwiridwe antchito
- kutalika kwa chingwe 200+ mita popanda zolumikizira
- kuyang'anira ndi kuyambitsanso ogula a PoE
- kuphweka ndi kusinthasintha kwa kasinthidwe.
Mwina pali njira zina pamsika zomwe zingakwaniritse zosowa zanga, koma sindinazipezebe.
Ndikuyitanitsa omwe akufuna kukambirana nkhaniyi ku Telegraph pamacheza omwe ndidapanga:
1. - Macheza ammutu pa Zyxel
2. - Macheza ammutu pa Mikrotik
