Security systems

Security systems supplies are always in high demand - as years go by, home security systems go up in technology and their prices drop down. Today you can get a pretty good alarm system for less then $100 - you can even can one for less then that over on ebay...
Security systems - and that's an important factor - are also getting smaller in size. I still remember that huge ugly box in my Dad's work place. That was an alarm system - it was big and ugly - and need constant fixing. Today these home security systems are much more reliable, most of them are wireless, and their size - well they are about the size of a big mac or something like that. Hardly noticeable...
The question is not whether or not you should get a home security system - but which security system would work best for you!
