Mazuva ano, kuongororwa kwevhidhiyo chinhu chakakosha mumararamiro ese ehupenyu.Kuvakwa kwema network mavhidhiyo ekutarisa masisitimu anoita kuti zvive nyore kutarisa nzvimbo dzeveruzhinji uye kuwana ruzivo.Zvisinei, nekuparidzirwa kwepamusoro-tsanangudzo uye kushandiswa kwehungwaru kwemakamera ekuongorora mavhidhiyo, zvinodiwa zvehutano hwehutachiwana hwevhidhiyo, stream bandwidth uye kureba kwekufambisa zvakagadziridzwa, uye maitiro emhangura emhangura aripo akaoma kuenzanisa.Ichi chinyorwa chichakurukura hurongwa hutsva hwe wiring hunoshandisa optical fiber wiring uye optical transceivers, iyo inogona kushandiswa muvhareji yeterevhizheni yekucherechedza zvirongwa (CCTV) uye IP network video monitoring systems.

Vhidhiyo yekutarisa system yekuongorora

Mazuva ano, vhidhiyo yekutarisa network iri kuramba ichinyanya kufarirwa, uye kune akawanda mhinduro dzekuvaka vhidhiyo yekutarisa masisitimu.Pakati pavo, CCTV yekutarisa uye IP kamera yekutarisisa ndiyo inonyanya kugadziriswa mhinduro.

Yakavharwa-inotenderera terevhizheni yekutarisa system (CCTV)
Mune yakajairwa yakavharwa-yetenderera terevhizheni yekutarisa system, yakagadziriswa analogi kamera (CCTV) yakabatana kune yekuchengetera mudziyo (senge cassette vhidhiyo rekodha VCR kana yedhisiki yedhisiki rekodhi rekodhi DVR) kuburikidza nekoaxial tambo.Kana iyo kamera iri PTZ kamera (inotsigira yakachinjika kutenderera, kutenderera uye zoom), imwezve PTZ controller inoda kuwedzerwa.

IP network vhidhiyo yekutarisa system
Mune yakajairwa IP network yevhidhiyo yekutarisa network, IP makamera akabatana kune yenzvimbo network kuburikidza neasina kuvharika-akamonyoroka-matambo tambo (kureva, Chikamu 5, Chikamu 5, uye mamwe ma network jumpers) uye switch.Yakasiyana nemakamera eanalogi ataurwa pamusoro apa, IP makamera anonyanya kutumira uye kugamuchira IP datagrams kuburikidza netiweki pasina kuvatumira kumidziyo yekuchengetedza.Panguva imwecheteyo, vhidhiyo yakatorwa ne IP kamera inorekodhwa pane chero PC kana sevha mune network.Chikuru chikuru che IP network video surveillance network ndechekuti imwe neimwe IP kamera ine yayo yakazvimirira IP kero, uye inogona kukurumidza kuzviwana. zvichibva pakero yeIP muvhidhiyo yese network.Panguva imwecheteyo, sezvo IP kero dze IP kamera dzinogadziriswa, dzinogona kuwanikwa kubva kumativi ese enyika.

Iko kudikanwa kweiyo optical fiber transceiver muCCTV/IP network vhidhiyo surveillance system

Ose ari maviri ataurwa pamusoro evhidhiyo ekutarisisa masisitimu anogona kushandiswa munzvimbo dzekutengesa kana dzekugara network.Pakati pavo, makamera akamiswa eanalog anoshandiswa muCCTV anowanzo shandisa coaxial tambo kana tambo dzisina kuchinjika dzakamonyoroka (pamusoro pechikamu chetatu network tambo) yekubatanidza, uye IP makamera anowanzo shandisa asina kuvharika akamonyoroka tambo dzepairi (pamusoro pechikamu shanu network tambo) yekubatanidza.Nekuti zvirongwa zviviri izvi zvinoshandisa copper cabling, zvakaderera kune fiber cabling maererano nekutapurirana kure uye network bandwidth.Nekudaro, hazvisi nyore kutsiva yazvino yemhangura cabling neoptical fiber cabling, uye pane zvinotevera zvinonetsa:

*Ntambo dzemhangura dzinowanzoiswa pamadziro.Kana maoptical fibers akashandiswa, tambo dzemaziso dzinoda kuiswa pasi pevhu.Nekudaro, izvi hazvigoneke kune vese vashandisi.Nyanzvi dzinodiwa kuti dzipedze kuisa, uye mari ye wiring haisi yakaderera;
* Pamusoro pezvo, zvechinyakare kamera midziyo haina kugadzirwa nefiber ports.

Tichifunga nezveizvi, iyo optical fiber wiring nzira inoshandisa fiber optic transceivers uye analog makamera / IP kamera yakakwezva kutarisa kwevatariri ve network.Pakati pavo, iyo optical fiber transceiver inoshandura chiratidzo chemagetsi chepakutanga kuita chiratidzo chemaziso kuti uone kubatana kwetambo yemhangura uye fiber optical.Ine zvinotevera zvakanakira:

* Hapana chikonzero chekufambisa kana kushandura iyo yapfuura mhangura tambo wiring, ingoona kutendeuka kwephotoelectric kuburikidza nekusiyana kwakasiyana pane optical fiber transceiver, uye batanidza tambo yemhangura uye optical fiber, iyo inogona kunyatso kuchengetedza nguva nesimba;
* Inopa bhiriji pakati pemhangura yepakati uye optical fiber yepakati, izvo zvinoreva kuti midziyo inogona kushandiswa sebhiriji pakati pemhangura tambo uye optical fiber zvivakwa.

Kazhinji, fiber optic transceivers inopa nzira inodhura yekuwedzera kureba kwekutapurirana kwetiweki iripo, hupenyu hwesevhisi yemidziyo isiri-fiber, uye kureba kwekutapurirana pakati pemidziyo miviri yetiweki.
