Choosing what cable to use for CCTV in Hyderabad is crucial for getting clear surveillance footage and ensuring long-term system reliability in the city’s varying climate conditions. Most CCTV installations in Hyderabad rely on high-quality RG59 coaxial cable paired with a power cable because it supports stable video transmission and works well for both indoor and outdoor setups. For longer distances or high-resolution cameras like HD, AHD, or 4K CCTV, using RG6 cable is recommended as it offers lower signal loss and better clarity. In commercial spaces, residential complexes, and outdoor areas exposed to heat and dust, many installers prefer Siamese CCTV cable since it combines video and power in a single line, reducing clutter and making the installation more durable.
