I kēia mau lā, ʻo ka nānā ʻana i nā wikiō he mea pono ʻole i nā ʻano āpau o ke ola. ʻO ke kūkulu ʻana i nā ʻōnaehana wikiō wikiō e maʻalahi ka nānā ʻana i nā wahi ākea a loaʻa ka ʻike. Eia nō naʻe, me ka hoʻolaha ʻana o nā noi kiʻekiʻe a me ka naʻauao o nā kāmela kiaʻi wikiō, ua hoʻomaikaʻi ʻia nā koi no ka maikaʻi o ka hōʻailona hōʻailona wikiō, ka bandwidth stream a me ka mamao o ka hoʻouna ʻana, a ua paʻakikī nā ʻōnaehana cabling keleawe e kū nei. E kūkākūkā kēia ʻatikala i kahi ʻōnaehana wili hou e hoʻohana ana i ka uwila fiber optical a me nā transceivers optical, hiki ke hoʻohana ʻia i nā ʻōnaehana hoʻopaʻa ʻana i ke kīwī kīwī (CCTV) a me nā ʻōnaehana wikiō wikiō IP.

ʻO ka nānā ʻana o ka ʻōnaehana wikiō

I kēia mau lā, ʻoi aku ka kaulana o nā pūnaewele nānā wikiō, a he nui nā mea hoʻonā e kūkulu i nā ʻōnaehana nānā wikiō. I waena o lākou, ʻo ka nānā ʻana o CCTV a me ka nānā ʻana i nā kāmela IP ka mea maʻamau.

Pūnaehana kiaʻi kīwī kaapuni paʻa (CCTV)
I loko o kahi ʻōnaehana nānā kīwī kaapuni paʻa maʻamau, hoʻopili ʻia kahi pahupaʻikiʻi analog paʻa (CCTV) i kahi mea hoʻopaʻa (e like me ka cassette video recorder VCR a i ʻole ka DVR hard disk video recorder) ma o ke kaula coaxial. Inā he pahupaʻikiʻi PTZ ka pahupaʻikiʻi (kākoʻo i ka hoʻololi ʻana i ke aniani, ke kili a me ka zoom), pono e hoʻohui ʻia kahi mea hoʻoponopono PTZ hou.

ʻōnaehana nānā wikiō IP pūnaewele
Ma kahi pūnaewele nānā wikiō IP maʻamau, hoʻopili ʻia nā pahu kiʻi IP i ka pūnaewele wahi kūloko ma o nā kaula wili-wili ʻole (ʻo ia hoʻi, Māhele 5, Māhele 5, a me nā mea lele pūnaewele ʻē aʻe) a me nā hoʻololi. ʻOkoʻa mai nā kāmela analog i ʻōlelo ʻia ma luna, hoʻouna nui nā kāmela IP a loaʻa i nā datagrams IP ma o ka pūnaewele me ka ʻole o ka hoʻouna ʻana iā lākou i nā mea mālama. I ka manawa like, ua hoʻopaʻa ʻia ka wikiō i hopu ʻia e nā kāmela IP ma kekahi PC a i ʻole server i ka pūnaewele. ma muli o ka helu IP ma ka pūnaewele wikiō holoʻokoʻa. I ka manawa like, no ka mea hiki ke ʻōlelo ʻia nā IP IP o nā kāmera IP, hiki ke kiʻi ʻia mai nā wahi āpau o ka honua.

ʻO ka pono o ka transceiver fiber optical ma CCTV / IP pūnaewele nānā wikiō wikiō

Hiki ke hoʻohana ʻia nā ʻōnaehana nānā wikiō ʻelua i ʻōlelo ʻia ma luna o nā ʻoihana ʻoihana a i ʻole ka hale noho. Ma waena o lākou, ʻo nā kāmela analog paʻa i hoʻohana ʻia ma CCTV e hoʻohana maʻamau i nā uwea coaxial a i ʻole nā ​​​​kauwela paʻa ʻole i pale ʻole ʻia (ma luna o ka ʻāpana ʻekolu mau kelepona pūnaewele) no ka hoʻopili ʻana, a hoʻohana maʻamau nā kāmela IP i nā kaula wili ʻole i pale ʻole ʻia (ma luna o ka ʻāpana ʻelima mau kaula pūnaewele) no ka pilina. Ma muli o ka hoʻohana ʻana o kēia mau ʻano ʻelua i ka cabling keleawe, ua haʻahaʻa lākou i ka fiber cabling ma ke ʻano o ka mamao o ka hoʻouna ʻana a me ka bandwidth network. Eia nō naʻe, ʻaʻole maʻalahi ka hoʻololi ʻana i ke kaula keleawe o kēia manawa me ke kelepona fiber optical, a aia nā pilikia aʻe:

* Hoʻopaʻa mau ʻia nā kaula keleawe ma ka paia. Inā hoʻohana ʻia nā fiber optical, pono e waiho ʻia nā uwea optical ma lalo o ka lepo. Eia naʻe, hikiʻole kēia i nā mea hoʻohana maʻamau. Pono nā poʻe loea e hoʻopau i ka waiho ʻana, a ʻaʻole haʻahaʻa ke kumukūʻai uea;
* Eia kekahi, ʻaʻole i hoʻolako ʻia nā mea kāmela maʻamau me nā awa fiber.

Ma ka nānā ʻana i kēia, ʻo ke ʻano o ka uwila fiber optic e hoʻohana ana i nā transceivers fiber optic a me nā kāmera analog / IP cameras ua hoʻohuli i ka manaʻo o nā luna hoʻomalu. Ma waena o lākou, hoʻololi ka transceiver fiber optical i ka hōʻailona uila mua i kahi hōʻailona optical e hoʻomaopopo i ka pilina o ke kaula keleawe a me ka fiber optical. Loaʻa iā ia nā pono penei:

* ʻAʻohe pono e hoʻoneʻe a hoʻololi paha i ke kaula keleawe ma mua, e ʻike wale i ka hoʻololi photoelectric ma o nā ʻokoʻa like ʻole ma ka transceiver fiber optical, a hoʻohui i ke kaula keleawe a me ka fiber optical, hiki ke mālama pono i ka manawa a me ka ikehu;
* Hāʻawi ia i kahi alahaka ma waena o ke keleawe keleawe a me ka fiber optical medium, ʻo ia ka mea hiki ke hoʻohana ʻia nā mea hana ma ke ʻano he alahaka ma waena o ke kaula keleawe a me nā ʻōnaehana fiber optical.

Ma keʻano laulā, hāʻawi nā transceivers fiber optic i kahi ala kūpono e hoʻolōʻihi i ka mamao o ka hoʻouna ʻana o ka pūnaewele e kū nei, ke ola lawelawe o nā mea hana non-fiber, a me ka mamao o ka hoʻouna ʻana ma waena o nā ʻaoʻao ʻelua.
