Data Cabling and Data Networking

Intelligent Security and Fire install telephone cabling, data cabling and data networks to provide you with a solid infrastructure for your home or business.

In today’s business environment it is essential to be able to store and transfer data whenever necessary. A customised data solution will allow you to connect to other users in your business to share files and resources, as well as being able to easily contact them using email or voice conferencing. This means that the way you do business could be revolutionised.

Private networks are formed by computers connected to each other but not to external networks or the Internet. These networks work on a local basis to allow all the users of the network to transmit data to one another, but do not allow others to see or access this data. A server can be used to store all of these shared files. Private networks can cover more than one site.


There are also private networks that allow for data sharing between several companies or sites using a virtual private network, or VPN. A VPN is used to achieve the security of a private network whilst connected to public networks and the Internet. As such, it is a method of securing public networks and not a private network in itself, but it offers increased functionality and an acceptable level of security for many small businesses. This allows you to access the private network from home or any other location by using the internet to replace cabling.
Advantages of a Private Network
  • According to Symantec the average cost of a data breach has risen for the fifth consecutive year. The 2011 Annual Study: UK Cost of a Data Breach found that the average cost per capita of a data breach rose to £79 per record, up from £71 in 2010 and 68 percent higher than £47 in 2007. Using a private network will help avoid this threat as the network is not accessible by individuals not using one of the connected local computers.
  • In the same way that private networks cannot be affected by people outside the network, they can also not be affected by technical difficulties outside the network. For example, should internet connectivity fail, or external servers go down, you will still be able to share data with other users.
Disadvantages of a Private Network
  • Whilst private networks provide excellent security, their isolation can be a drawback. No information enters the network from other networks, and you cannot transmit from the private network to another. In the case of a residential house on a private network, for example, residents could send data to each other but would not be able to access the internet.
  • Because the internet has millions of users, the costs of maintaining it are widely dispersed. With a private network, however, expenses like server space and cabling rests on the network operator.
Advantages of a VPN
  • Allows remote access to a network that is still protected, so you can work from anywhere.
  • Allows data to be easily shared between sites and companies.
  • Eliminates the need for long-distance leased lines due to using the internet in place of cabling, which also reduces long-distance telephone charges.
  • Reduces support costs, due to maintenance costs being shared across the internet’s users..
Disadvantages of a VPN
  • Using a VPN securely takes expertise and knowledge of network security at every stage- whether installation or maintenance. Users should also be educated on how to avoid a security breach.
  • The reliability and performance of an Internet-based VPN is not under an organization's direct control. Instead, the solution relies on an ISP and their quality of service. 
  • Historically, VPN products and solutions from different vendors have not always been compatible due to issues with VPN technology standards. Attempting to mix and match equipment may cause technical problems, and using equipment from one provider may not give as great a cost savings.


Your data cabling could serve you for over ten years, longer than any other part of your network, yet it accounts for a relatively small percentage of the IT budget. Networks are rarely static environments and your cabling system should allow for growth and be flexible. Once your cabling system is installed, changes can be disruptive and expensive so it is essential to get it designed and installed correctly first time. With our twenty years in the cabling business, Intelligent Security and Fire can design and install a system that is customised for your needs.

You can benefit from excellent value and service by asking Intelligent Security and Fire to survey your premises free of charge. We will respond quickly and you'll get a professionally written design and proposal for a solution that meets your current needs and provides for your future growth to match both your budget and bandwidth.
