Mazuva ano, kutariswa kwevhidhiyo chinhu chinonyanya kukosha kune ese mafambiro 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 hwechiratidzo chekufambisa kwevhidhiyo, rwizi bandwidth uye kureba kwekufambisa zvakagadziridzwa, uye maitiro emhangura emhangura akaoma kuenderana.

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 yekutarisa ndiyo yakajairika mhinduro.

Yakavharwa-inotenderera terevhizheni yekutarisa system (CCTV)
Mune yakajairwa yakavharwa-yedunhu 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. Kusiyana nemakamera eanalog ataurwa pamusoro, IP makamera anonyanya kutumira uye kugamuchira IP datagraphs kuburikidza netiweki pasina kuvatumira kumidziyo yekuchengetedza. Panguva imwecheteyo, vhidhiyo yakatorwa neIP kamera inorekodhwa pane chero PC kana sevha mune network. Chinhu chikuru cheIP network vhidhiyo yekutarisa network ndechekuti yega yega IP kamera ine yayo yakazvimirira IP kero, uye inogona kukurumidza kuzviwana yakavakirwa paiyo IP kero mune yese vhidhiyo 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 ekutarisa 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) kubatanidza, uye IP makamera anowanzo shandisa asina kuvharika akamonyoroka tambo dzepairi (pamusoro pechikamu shanu network tambo) yekubatanidza. Sezvo ese ari maviri ezvirongwa izvi anoshandisa copper cabling, iwo akaderera kune fiber cabling maererano nekufambisa kure uye network bandwidth. Nekudaro, hazvisi nyore kutsiva iyo yazvino yemhangura cabling ne optical fiber cabling, uye kune anotevera matambudziko:

*Ntambo dzemhangura dzinowanzoiswa pamadziro. Kana ukashandisa optical fibers, unofanira kuisa tambo dzemaziso 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 neoptical fiber ports.

Tichifunga nezveizvi, iyo optical fiber wiring nzira inoshandisa optical fiber transceivers uye analog makamera / IP makamera akakwezva kutarisa kwemanetiweki vatariri. 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;
*Ipa bhiriji pakati pemhangura yepakati uye optical fiber yepakati, zvinoreva kuti mudziyo unogona 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.
