I have heard of monotronics only becuase i get tons of people knocking on my door telling me they are not sales men but just letting the neighboorhood know about the crime in the area, but they are authorized to give away a free alarm to just a lucky few.. as long as we place their signs in our yard. And it will only cost me $40 per month for service but you have to sign a 3 year contract too!
Its cheaper to just pay a few hundred for your alarm and install it yourself and just use a service like
AlarmRelay to monitor for $9 month
