When I bought my first home, the first thing that I did was install a new security system. That meant comparing quite a few residential alarm systems until I found the one with the features I really wanted. Five years later, I'm still happy with my choice. In my case, certain features were especially important. The ability to access the system remotely was a big plus. Since I live alone, a system that I could use to summon help if I became ill or sustained a nasty fall also mattered. If you are thinking of installing a new system, let me provide some food for thought. By deciding what features you really need, it will be easier to focus on systems that are worth your time and your money.
