Cov ntsiab lus yuav:
Ob lub cables yuav tsum muaj rau CCTV system, coaxial cable thiab fais fab cable. Coaxial cable xa cov yees duab los ntawm lub koob yees duab mus rau lub recorder. Lub hwj chim cable xa hluav taws xob los ntawm lub zog hluav taws xob (piv txwv li lub adaptor) mus rau lub koob yees duab.
Es tsis txhob yuav ib coaxial cable thiab ib lub hwj chim cable cais los yog ib tug neeg, koj muaj peev xwm cia li yuav Siamese RG59 cable raws li nws combines coaxial video cable nrog lub hwj chim cable rau hauv ib tug cable.
Yuav ua li cas xaiv txoj cai coax cable?
Hauv CCTV system, cov teeb liab video tau kis los ntawm coaxial cable. Yog li, yuav ua li cas xaiv txoj cai ntawm coax cable yog cov kauj ruam tseem ceeb. Coaxial cable yog tsim los xa cov video zaus ntau yam nrog qhov tsawg kawg nkaus distortion lossis attenuation, ua rau nws xaiv zoo rau CCTV. Txawm li cas los xij, qhov tsis tsim nyog lossis qis dua - qib coaxial cable tuaj yeem ua rau tag nrho cov teeb liab kis tau tus mob thiab tso cai rau sab nraud EMI / RFI cuam tshuam los nkag rau hauv lub teeb liab ua rau muaj suab nrov. Qhov no yeej ua rau cov duab tsis zoo.
Yog li, rau qhov ua tau zoo tshaj plaws, nco ntsoov teeb tsa koj lub cable nrog cov khoom siv tooj liab liab thiab tooj liab braiding nrog min{0}}% kev pab them nqi.
Txawm li cas los xij, yog tias koj nyiam tus nqi qis, koj tuaj yeem xaiv CCA tus neeg xyuas pib nrog CCA braiding thiab qis dua. Kom paub meej, vedio zoo yuav tsis zoo li cov khoom siv tooj liab.
