How do Fiber Optic Cabling Installations Affect the CCTV Network?

Application of fiber optics in CCTV

traditionally, the CCTV cameras have used the coaxial cables to broadcast the footages based on analog technology. However, with the advent of sending the digitized, compressed videos across the local networks that use Ethernet cables, the demand for better video signals and quality increased drastically. Though the coaxial cables are easy and convenient to install, the integration of CCTV network with the local area network has caused the shift to fiber optic cabling installations.

Role of fiber optic cabling installations for CCTV network

The limitations of the coaxial cables like their susceptibility to interference and restricted link distance to mere hundreds of meters can be fixed with the help of fiber optic technology. Very high bandwidth, high-strength cables which are immune to external electrical interference are the reasons why the fiber optic cabling installations are preferred over the coaxial cables for CCTV networks of late.

How did the fiber optic cabling installations affect different types of CCTV cameras?

We can observe a huge surge in the CCTV camera installations across the world over the past 15 years. Of late, the CCTV cameras are ubiquitous and demanding better performance than in the past for high-quality transmission over large distances.

Analog Systems:

As mentioned, the analog systems have always used coaxial or the UTP cables to send the images to the digital video recorder (DVR); however, the DVR essentially being a network device has changed everything. Though the video from the CCTV camera is transmitted in the analog format, the live and recorded videos are transmitted over the LANs. The low cost of the analog CCTV cameras and the unparalleled video quality output are the factors that are still keeping the analog systems in the game competing with the IP and the SDI CCTV cameras.
Now, the fiber optic cabling installations have helped in addressing the increased bandwidth requirements, especially with the digital-analog systems which need a high bandwidth of 90-300MHz.

IP Systems:

IP CCTV cameras offer the flexibility of placing the surveillance cameras in remote places along with the ease of integrating the security network with the LAN. Due to the need for coverage across long distances, the fiber optic cabling is ideal for IP based CCTV cameras.

SDI Systems:

The Serial Digital Interface (SDI) CCTV cameras are the ultimate and the latest technology in the CCTV genre. These are reserved to the high-security zones like the airports where the margin for error is expected to be the least.
The SDI system functions more like the analog systems where the coaxial cable is used to transmit the images across the CTV network. However, such transmission distances are very limited and this is where the application of the fiber optic cabling installations becomes essential to tap the growing need of SDI systems.
