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).

In the ever expanding world it is essential that electronic security companies such as ourselves become expert installers of appropriate switch networks and fibre optic cabling. End users are often disappointed when, having spent many of thousands of pounds on a brand new, state of the art, IP CCTV system that live images are slow to appear or frequently 'drop off' the screen. Invariably this is due to the CCTV company advising that the client's existing (and normally inadequate) network can be utilised or taking it upon themselves to install an incorrectly specified switch network.

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.

There are different types of network cable, and the appropriate type to use 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 cable is 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 is specified where high bandwidth is needed; especially in an environment and where an installation demands high capacity, typically a hospital, airports, banks....Fibre optic is fast becoming the medium of choice for any installation that is sending high volumes of data!

In order to ensure that Sygma can be relied upon to give the correct advice and provide an expert installation service we have, over many months, spent time and money ensuring that our engineers attend courses and gain accreditations in the complex area of data networking.

We are pleased to say that as a result of this, and investment in the latest network test equipment, that we are now able to offer a 25 year guarantee on all new data network cables installed by us.
