Masiku ano, kuyang'anira makanema ndichinthu chofunikira kwambiri m'magulu onse amoyo. Kupanga makina owonera makanema pa intaneti kumapangitsa kuti pakhale kosavuta kuyang'anira malo omwe anthu ambiri amapeza komanso kupeza zambiri. Komabe, ndi kutchuka kwa tanthawuzo lapamwamba ndi ntchito zanzeru zamakamera owonetsetsa mavidiyo, zofunikira za khalidwe lachidziwitso chotumizira mavidiyo, mtsinje wa bandwidth ndi mtunda wotumizira zakhala zikuyenda bwino, ndipo machitidwe amkuwa omwe alipo ndi ovuta kugwirizana.

Kanema wowunika dongosolo mwachidule
Masiku ano, makanema owonera makanema akuchulukirachulukira, ndipo pali njira zambiri zopangira makina owonera makanema. Pakati pawo, kuyang'anitsitsa kwa CCTV ndi kuyang'anitsitsa kamera ya IP ndi njira zodziwika bwino.

Makina owonera kanema wawayilesi wotsekedwa (CCTV)
Mu njira yowonera kanema wawayilesi wotsekedwa, kamera ya analogi yokhazikika (CCTV) imalumikizidwa ku chipangizo chosungira (monga chojambulira makanema a VCR kapena chojambulira cha digito cha hard disk DVR) kudzera pa chingwe cha coaxial. Ngati kamera ndi kamera ya PTZ (imathandizira kusinthasintha kozungulira, kupendekera ndi makulitsidwe), chowongolera chowonjezera cha PTZ chiyenera kuwonjezeredwa.

IP network yowonera makanema
Mu mawonekedwe a IP network surveillance network, makamera a IP amalumikizidwa ndi netiweki yakumaloko kudzera mu zingwe zopindika zosatetezedwa (mwachitsanzo, Gulu 5, Gulu 5, ndi ma jumper ena a netiweki) ndi ma switch. Mosiyana ndi makamera a analogi omwe tawatchulawa, makamera a IP makamaka amatumiza ndi kulandira ma datagrams a IP kudzera pa intaneti popanda kuwatumiza kuzipangizo zosungirako. Nthawi yomweyo, kanema wotengedwa ndi makamera a IP amalembedwa pa PC kapena seva pa intaneti. Chofunikira chachikulu pa intaneti ya IP network surveillance network ndikuti kamera iliyonse ya IP ili ndi adilesi yake yodziyimira payokha, ndipo imatha kudzipeza yokha kutengera adilesi ya IP pamaneti onse amakanema. Panthawi imodzimodziyo, popeza ma adilesi a IP a makamera a IP amatha kutha, amatha kupezeka padziko lonse lapansi.

Kufunika kwa optical fiber transceiver mu CCTV/IP network network surveillance system

Onse omwe tatchulawa mavidiyo anaziika machitidwe angagwiritsidwe ntchito malonda kapena zogona malo maukonde. Pakati pawo, makamera a analogi osasunthika omwe amagwiritsidwa ntchito mu CCTV nthawi zambiri amagwiritsa ntchito zingwe za coaxial kapena zingwe zopotoka zosatetezedwa (pamwamba pamagulu atatu a netiweki zingwe) kuti alumikizane, ndipo makamera a IP nthawi zambiri amagwiritsa ntchito zingwe zopotoka zosatetezedwa (pamwamba pagulu la zingwe za netiweki zisanu) kuti alumikizane. Popeza ziwembu zonsezi zimagwiritsa ntchito copper cabling, ndizotsika poyerekeza ndi fiber cabling potengera mtunda wotumizira ndi bandwidth ya netiweki. Komabe, sikophweka kuyika cabling yamkuwa yomwe ilipo panopa ndi kuwala kwa fiber cabling, ndipo pali zovuta zotsatirazi:

*Zingwe zamkuwa nthawi zambiri zimakhazikika pakhoma. Ngati mugwiritsa ntchito ulusi wa kuwala, muyenera kuyala zingwe za kuwala mobisa. Komabe, izi sizingatheke kwa ogwiritsa ntchito wamba. Akatswiri amafunika kuti amalize kuyika, ndipo mtengo wa waya siwotsika;
* Kuphatikiza apo, zida zamakamera azikhalidwe sizikhala ndi madoko owoneka bwino.

Poganizira izi, njira yopangira ma waya yomwe imagwiritsa ntchito ma transceivers optical fiber ndi makamera a analogi / makamera a IP yakopa chidwi cha oyang'anira maukonde. Pakati pawo, transceiver ya optical fiber imatembenuza chizindikiro choyambirira chamagetsi kukhala chizindikiro cha kuwala kuti azindikire kugwirizana kwa chingwe cha mkuwa ndi kuwala kwa kuwala. Lili ndi zabwino izi:

* Palibe chifukwa chosuntha kapena kusintha waya wamkuwa wamkuwa wam'mbuyo, ingozindikirani kutembenuka kwa photoelectric kudzera m'malo osiyanasiyana pa transceiver ya fiber optical, ndikugwirizanitsa chingwe chamkuwa ndi kuwala kwa fiber, zomwe zingathe kupulumutsa nthawi ndi mphamvu;
* Perekani mlatho pakati pa copper medium ndi optical fiber medium, zomwe zikutanthauza kuti chipangizocho chitha kugwiritsidwa ntchito ngati mlatho pakati pa chingwe cha mkuwa ndi zida za fiber optical.

Kawirikawiri, ma transceivers a fiber optic amapereka njira yotsika mtengo yowonjezera mtunda wotumizira wa intaneti yomwe ilipo, moyo wautumiki wa zipangizo zopanda fiber, ndi mtunda wotumizira pakati pa zipangizo ziwiri za intaneti.
