Fibre-to-the-home: The impact on your security

Residential Estate Security Handbook 2016 - Vol 2 Editor's Choice, Infrastructure, Residential Estate (Industry)

Security and access control are predominant concerns in many communities across South Africa. One of the synergistic benefits of the deployment of optical fibre in your area is the possibility to enable some significant peripheral benefits that take advantage of that infrastructure and medium.

The demand for fibre-to-the-home (FTTH) is exploding across South Africa at the moment. Consumers are becoming more technically aware and have developed a keen appreciation for the benefits of access to a stable and fast broadband network, furthermore consumers are demanding choice. The days of being locked-in to the monolithic vertically integrated all-consuming telcos are numbered.

Consumers are tired of hearing ‘Your call is important to us you are caller number 126 in the queue…’ they want to experience better service and certainly don’t want to be ripped off while using it. The market dynamic has shifted and with the entrance of multiple new service providers, particularly in the ‘open-access’ FTTH space, consumers are reaping the benefits.

Optical fibre is very well positioned to address the needs for high quality video based security requirements. The good news is that not all fibre networks have to be completely trenched in your neighbourhood and you don’t have to suffer the inconvenience of extensive civil works ripping up your roads and pavements. There are approved and tested technologies today that take advantage of existing wastewater pipes to deploy optical fibre. This effectively speeds up deployment, lowers the cost and improves the reliability of the underlying network without adversely affecting the effectiveness of the existing water infrastructure.

Cutting out the limitations

With a transition from analogue to digital video continuing, there remains a crucial requirement for reliable transmission of the video signal between camera and control room. With many legacy installations it has been copper based coaxial cable or unshielded twisted pair (UTP) handling images from a camera to monitor, recorder or both. Copper cables have their limitations, including restricted transmission distance, signal degradation over long cable distances, interference, copper theft and damage from lightning.

In some installations, wireless transmission–radio-frequency, microwave, Wi-Fi and mesh nets–play a role. Most enterprise security video designs are not totally wireless. The technology is applied to meet certain geographic or operational challenges.

And then there is fibre-optic cabling, with its interference immunity, better inherent security, robust distances and significantly better bandwidth capability using light as the carrier, this boasts significant advantages:

• Better-quality transmission.

• No interference from lightning strikes, short circuits, crosstalk, electro-magnetic or radio signal interference.

• No interference from high voltages in fluorescent lights, card-access door strikes or outdoor lighting systems.

• Better-quality transmission.

• Light weight.

• Stable within a wide temperature range.

• Long service life.

• Secure–not easily tapped into or interfered.

• Extremely high bandwidth (for CCTV and sound).

• Immune to copper theft.

Deploying fibre-optic cables is an expensive operation, not only in the initial capital outlay but it also requires specialised training, skills and test equipment to maintain and operate effectively. This is something that residents associations should best leave to the experts and not fall into the trap of building and operating their own networks.

With the intense focus on building FTTH networks across South Africa, there is no better time for homeowner’s associations and residential or business estate developers to leverage the FTTH industry to make infrastructure available to community-based security access control and surveillance networks and save the costs of duplicating this infrastructure themselves. It just makes sense.
