Firstly, it’s important to acknowledge that “Advance Star India,” situated in Delhi, is recognized as an authorized dealer for the D-Link CCTV Standard 90MTR Cable (3+1), a product relevant to your security infrastructure needs in Faridabad, Haryana, India.

Essentially, this refers to a composite cable specifically engineered for analog CCTV (Closed-Circuit Television) installations over a defined distance of 90 meters, a common requirement for surveillance setups in various locations, including within our region.

The “(3+1)” designation fundamentally describes the combination of distinct cables integrated within a single protective outer jacket, offering a convenient and streamlined solution for your CCTV system:

Firstly, it incorporates One Coaxial Cable.

Specifically, this primary cable serves the crucial function of transmitting the vital video signal directly from the CCTV camera unit to the Digital Video Recorder (DVR).

Therefore, it typically features a characteristic 75-ohm impedance, most likely adhering to the widely adopted RG59 type specification, ensuring proper signal matching and efficient transfer of video data within your surveillance system.

Furthermore, it includes a copper conductor at its core, surrounded by appropriate insulation materials and shielding layers. 

Consequently, this careful construction ensures the delivery of good signal quality, minimizing potential signal loss over the 90-meter run and effectively reducing susceptibility to external electromagnetic interference (EMI) that could degrade your surveillance footage.
