Install a security system theself

alarmSecurity

I just bought a new home and it had been professionally pre-wired for a security system. There are cables for sensors on all entry doors. There are some cables for motion detectors as well on the main floor. There is also a cable for the control panel near the main entrance. All the cables go to the basement and are not connected to anything at the moment.

I checked one of the cables and it looks like there are four wires – red, black, yellow, and blue – inside.

Is this something I can make one of my DIY projects? If so, any recommendations on wired security systems compatible with this setup?

This is actually relatively easy - many hobby shops (eg Maplin in the UK) have kits which require very little technical know-how.

I guess the pre-requisites are:

Understanding your perimeter -

  • use break sensors on the highest risk areas (doors and easily accessible windows)
  • use motion sensors in key hallways
  • do you include your garage
  • do you include external sensors
  • do you want to trigger a camera or similar

Control requirements -

  • where will your control panel need to be?
  • should it have a panic alarm

Compatibility requirements -

  • break sensors may be passive, or may be powered. If powered, what voltage is required
  • usually easiest to go with one brand throughout
