Data Network Services

Video surveillance based on digital IP technology is revolutionizing the physical security industry. The network is a crucial element in any surveillance installation because it enables all the other surveillance functions - transmitting video streams so they can be viewed and stored, and carrying power to the cameras themselves using Power over Ethernet (PoE).

How it works

Network cables are predominantly used to connect and transfer data and information between computers, routers, switches and storage area networks. Cables are essentially the carrier or media through which data flows.

Network Cable Types

Different types of data network cables

There are different types of network cables, and the appropriate type to use for your business will depend on the structure and topology of the overall architecture of the system. The most commonly used types of network cables are dominated by what is referred to as “twisted pair cable”. In local area networks, twisted pair cable is by far the most commonly used type of cable.

Twisted Pair Cables

Used in many ethernet networks. Comprising of four pairs of thin wires or conductors, these wires are contained inside of the insulation or outer sheath of the cable. Each pair is twisted into several additional twists. These twists are to prevent interference from other devices and indeed from other adjacent cables.

Fibre Optic Cabling

This type of cabling is specified where high bandwidth is needed; especially in an environment and where an installation demands high capacity, typically in buildings such as hospitals, airports, banks etc. Fibre optic is fast becoming the medium of choice for any installation that is sending high volumes of data.
