Wireless networks are feasible though despite claims to the contrary are not 100% secure so putting your security system or sensitive computer connection on a wireless connection may provide flexibility but does expose a weak link in the system which the determined could break into.

To provide maximum flexibility it is a good idea to run a cable from the central command point to each room where control is required for each of the following elements:-

• 1 x RG59/u for video - transmit
• 1 x RG59/u or 1 x Cat5e for video receive from security CCTV
• 1 x Cat5e for computer network
• 1 x cat5e for telephone (four lines possible per cable)
• 1 x cat5E as a control wire (increasingly this will become a common control protocol for lighting, heating and new equipment – fridges, cookers, washing machines will doubtless have PC chips within a few years, some already do)
• 1 x Cat5e for future expansion
• All cables to be bunched and sleeved enabling a single pull through at first fix
• Cables terminate in a recessed wall panel with the appropriate cable sockets.
• Cable runs to be pipe encased for future access.
• 1 x fish wire per run – separate to initial first fix bundle (enables future cables to be pulled through)
• In a two storey house cables are best run from ground floor to first floor and run through void between ground and first floor and then run up/ down walls to required points.
• Central command point should be located within the main fabric of the building this can be in a utility room, basement, a garage can be used but security may be an issue. With this infrastructure in place the system may then be added to and configured without limit to the number or type of devices used, providing the room in question does have a patch panel.
