The reason you get a deduction may not be the reason you think it is. It might be political; insurance companies can't be seen as not encouraging homeowners to protect themselves. It might be financial; they knock a measly percentage off your insurance and Brinks and ADT give them 2x that in a kickback. I don't know either, but I do know alarms don't do what we're told they do. Here's a 2002 US Department of Justice report explaining the problems. Newer reports from local and federal agencies read similarly, in my experience. http://www.cops.usdoj.gov/pdf/e05021556.pdf http://www.cops.usdoj.gov/pdf/e05021556.pdf > The vast majority of alarm calls–between 94 and 98 percent–are false (higher in some jurisdictions). In other words, reliability of alarms, which can be measured using these false rates, is generally between 2 and 6 percent. Nationwide, false alarms account for 10 to 25 percent of all calls to police.
