ABOUT EZOCABLE

APPLICATION

This coaxial cable is specially designed for CCTV application. We have used our experience and advanced automated production techniques to develop a full line of CCTV cables that deliver premium performance and the highest quality CCTV reception at exceptional pricing.

CABLE FOR OPTIMUM CCTV SYSTEM PERFORMANCE

Today' s CCTV systems are more complexx and sensitive than ever. Using the proper type and quality of CCTV cable is a critical element of a properly operating system. Quality cable has always been essntial in delivering quality picture reception for CCTV system. EZO Cable now offers CCTV cables to meet the highest performance standards and safety ratings.

CHOOSING THE CORRECT CABLE

A variety of factors go into the design and construction of coaxial cables used for CCTV purposes.

SOLID COPPER CENTER CONDUCTORS

CCTV Video signals can range from a frequency of 2 Mhz or lower ( horizontal and vertical sync pulse information) to frequency of 450 Mhz or higher ( video information) . Since systems operate at frequencies of 2 to 4 Mhz, coaxial cables with solid copper center conductors must be used. At these low frequencies, the RF signal is carried closer to the center of the conductor, a phenomenon called ' skin effect' . If a copper covered steel center conductor is used, the low frequency RF signal would be running through the steel which would result in much greater attenuation ( loss) on the signal causing problems on long cable runs. Because of skin effect, solid copper center conductors should always be used with CCTV security system.

FOAMED DIELECTRICS

The dielectric materials used in coaxial cable can be solid or foamed. However, foamed dielectric is recommended because it has a lower dielectric constant which results in lower attenuation ( loss) and lower Capacitance. These properties are critical and greatly affect the quality of the transmitted CCTV video signal.

COPPER-BRAID SHIELDING

Shielding on coaxial cable can be made of various construction such as copper braid, alumunium foil with tinned copper braid, or alumunium foil with alumunium braid. At low frequencies, copper braid shields are normally used. Most security industry experts and CCTV equipment manufactures recommend using copper braids or tinned copper, which is used with alumunium foil. Both will provide low DCR ( direct current resistance) , enabling proper system performance with a low resistive return through the braid wire. Foil and tinned copper shielding should be considered in areas where high external RF interference is expected.
