Hi I am looking for guidance/advice with the installation of an alarm system. I have recently moved into a 3 bed end of terrace and feel an alarm is a sensible addition. Ideally I would like to install it myself. I have done some research and I'm more confused than ever. I have been told that alarm systems not 'connected' to the local police station are a waste of time and that wireless systems are unreliable. Help please, I bow to your superior knowledge
