Maitiro Ekusarudza Cable Yakanakisisa Yekuisa CCTV
Munyika yanhasi iri kuramba ichiwedzera kuoma, kuchengetedzeka kwave chinhu chakakosha. Imwe nzira yekuchengetedza kuchengetedzeka kwepfuma ndeyekuisa makamera eCCTV. Makamera eCCTV (Closed Circuit Television) anobatsira kutarisa nekunyora zviitiko zvinoitika panzvimbo. Kuti sisitimu yeCCTV ishande zvakanaka, kusarudza tambo yakakodzera kwakakosha. Chinyorwa chino chichatsanangura zvakadzama masarudzo etambo yakanakira kuiswa kweCCTV yako, tichifunga nezvezvinhu zvakasiyana-siyana zvakakosha zvakaita serudzi rwetambo, mhando, uye zvinodiwa nesystem.
Mhando dzeTambo dzeCCTV
Kune mhando dzakasiyana dzetambo dzinowanzoshandiswa mukuisa CCTV, imwe neimwe ine zvayakanakira nezvayakaipira. Heano mamwe emhando dzakajairika:
1. Tambo yeCoaxial
Tambo yeCoaxial ndeimwe yedzakakurumbira paCCTV systems dzemazuva ano. Rudzi urwu rwetambo runouya mumhando mbiri huru: RG59 neRG6.
– RG59: Tambo iyi yakakodzera daro pfupi kusvika pakati nepakati, inosvika mamita 200-300. Nepakati diki pemhangura, RG59 inochinjika uye iri nyore kushandisa muzvivakwa zvidiki kana zvepamba.
– RG6: Tambo iyi ine core yemhangura yakakura uye insulation yakakora, zvichiita kuti ive yakakodzera daro refu rinosvika mamita 450. Zvisinei, tambo iyi yakaoma kupfuura RG59, saka ingangoda kushanda nesimba panguva yekuisa.
2. Tambo Yakamonyoroka (Tambo Yakamonyoroka)
Tambo dzakatwasuka, dzakadai seCat5e kana Cat6 UTP (Unshielded Twisted Pair), dzinowanzoshandiswa muma network emakombiyuta asi dzinogonawo kushandiswa muma CCTV systems uchishandisa ma video baluns.
– Cat5e: Tambo iyi inokwanisa kutumira data kusvika ku100Mbps uye yakakodzera daro rinosvika kumamita zana.
– Cat6: Tambo iyi inopa kumhanya kwakanyanya, kusvika 1Gbps, uye inogona kushandiswawo padaro remamita zana asi ine masaini ari nani.
3. Tambo yeFiber Optic
Pakuisa tambo refu (dzinopfuura mamita mazana mashanu), tambo ye fiber optic ndiyo sarudzo yakakodzera. Tambo iyi inoshandisa girazi kana purasitiki kufambisa masaini echiedza, izvo zvinogona kupa kujeka kuri nani uye kugadzikana kupfuura tambo dzemhangura. Kunyange zvazvo ichidhura uye yakaoma kuisa, tambo ye fiber optic yakakodzera masisitimu makuru eCCTV akadai senhandare dzendege, nhandare dzemitambo, kana nzvimbo dzemaindasitiri.
Hunhu hweCable
Hunhu hwetambo hunonyanya kusarudza mashandiro eCCTV system yako. Zvimwe zvinhu zvekufunga nezvazvo pakuongorora hunhu hwetambo ndeizvi:
1. Zvinhu zveKutungamirira
Tambo dzine maconductor emhangura yakachena dzinowanzoita basa rakanaka kupfuura tambo dzakagadzirwa nealuminium alloys kana cladding. Mhangura yakachena ine conductivity yakanyanya, zvichiita kuti data ritapurirwe zvakanaka uye kukanganiswa kushoma.
2. Chigadziko chekudzivirira
Kudzivirira kwakanaka kunodzivirira tambo kubva pakukanganiswa nekunze uye kukuvara kwemuviri. Sarudza tambo dzine kudzivirira kupisa kunodzivirira mamiriro ekunze uye dzinodzivirira moto kuti dzishandiswe panze.
3. Kudzivirira
Kuti electromagnetic interference (EMI) isapindire, tambo dzine simbi dzinodzivirira dzinonyanya kufarirwa. Rutivi urwu runobatsira kuchengetedza kunaka kwemasaini uye kudzivirira kukanganiswa kubva kune zvimwe zvishandiso zvemagetsi zviri pedyo.
Kureba kweCable uye Kuverenga Kureba
Kunzwisisa daro riri pakati pekamera neDVR/NVR (Digital/Network Video Recorder) kwakakosha pakusarudza tambo yekushandisa. Iva nechokwadi chekuyera daro nemazvo uye sarudza tambo inogona kuibata pasina kurasikirwa kukuru kwehunhu hwechiratidzo. Semuenzaniso, kana daro racho riri kupfuura mamita zana, uchatanga kuona kudzikira kwehunhu netambo yeCat5e, saka ungangoda kufunga nezveCat6, tambo yemhando yepamusoro yecoaxial, kana kunyange fiber optic.
Zvimwe Zvekufunga nezvazvo
Kunze kwerudzi uye mhando yetambo, kune zvimwe zvinhu zvakati wandei zvinofanirwa kufungwa nezvazvo pakusarudza tambo yakanakira kuiswa kweCCTV, zvinosanganisira:
1. Rudzi rweKamera uye Tekinoroji
Rudzi rwekamera yeCCTV yauri kushandisa (analog, digital, HD, kana IP) ndiyo inogona kusarudza rudzi rwetambo rwakakodzera. Makamera eanalog anowanzo sarudza tambo dzecoaxial, nepo makamera eIP anonyanya kukodzera tambo dzakamonyoroka (Cat5e kana Cat6).
2. Nzvimbo Yekuisa
Nzvimbo iyo tambo ichaiswa inewo simba guru. Kana ikaiswa panze kana munzvimbo ine mamiriro ekunze akaipisisa (kupisa, kutonhora, hunyoro), iva nechokwadi chekusarudza tambo yakagadzirirwa kutsungirira mamiriro iwayo.
3. Budget
Bhajeti rinokanganisawo kusarudza tambo. Kunyange zvazvo tambo dzemhando yepamusoro, dzakadai sefiber optic, dzichipa mabhenefiti akawanda, mutengo wakakwira ungasave wakakodzera zvinodiwa papurojekiti nguva dzose. Zvakakosha kuwana chiyero pakati pemhando yepamusoro nebhajeti iripo.
4. Kubatana uye Kuenderana
Uyewo, funga nezvekuti tambo inoenderana sei nemidziyo yeCCTV yauchashandisa. Iva nechokwadi chekuti ma connectors aripo anoenderana nemaports ari pakamera neDVR/NVR. Semuenzaniso, tambo dze coaxial dzinowanzoda ma BNC connectors, nepo tambo dzakatwasuka dzichishandisa ma RJ45 connectors.
Mhedziso
Kusarudza tambo yakanakira kuiswa kweCCTV hakusi nyore. Kunyatsofunga kunodiwa kuti uve nechokwadi chekuti CCTV system yako inoshanda zvakanaka uye inopa kuchengetedzeka kwakanyanya. Pakusarudza tambo, iva nechokwadi chekutarisa mhando yetambo uye mhando, daro rekuisa, mhando yekamera, nzvimbo, bhajeti, uye kuenderana kwemudziyo. Nekuronga kwakanaka uye kusarudza kwakakodzera, haungochengete mari chete asiwo unowedzera mashandiro eCCTV system yako.
Yeuka kuti kuchengetedzeka inguva refu yekudyara, uye mhando yetambo chikamu chakakosha chekudyara ikoko. Usazeza kubvunza nyanzvi yekuisa CCTV kana nyanzvi kuti ikupe mazano anoenderana nezvaunoda. Nekusarudza tambo yakakodzera, unogona kuve nechokwadi chekuti CCTV system yako inoshanda zvakanaka uye yakavimbika, ichipa kuchengetedzeka kwaunoda.
