6.2 Video
Video output level of the camera, in standard of 1Vp-p, is delivered with female
BNC connector at 75 ohms impedance. To transmit the video to receiver properly, it
is recommended to use RG-59 A/U coaxial cable with stranded center conductor,
with male BNC connectors on both ends.
RG-59 is also in 75 ohm impedance, which matches the
camera’s output impedance. The A/U version is
recommended, rather than the version B/U, due of its
superior performance on flexibility for resisting severe
twisting, bending and other stresses which occur in many
CCTV installations.
In case the installation distance is over than 500 meters (1,500 feet), additional
amplifier might be needed to keep the video level and image quality.
