75 Ohm coaxial cables are a type of cabling commonly used in CCTV video surveillance systems to transmit video signals from cameras to recorders. They are constructed with a single central copper conductor surrounded by a layer of insulation, followed by a shield and an outer protective jacket.
Key Features:
Impedance: 75 Ohms - This is a crucial property that ensures the cable's impedance matches that of CCTV devices, minimizing signal loss and reflections.
Construction: Central conductor, insulation, shield, outer jacket - These provide protection for the signal against electromagnetic interference (EMI) and mechanical damage.
Applications: CCTV surveillance systems, analog video signal transmission, cable TV systems.
