When evaluating the initial investment required to add a security system to your home, the average cost can range from $250 to more than $1,000 depending on the system, equipment and installation that you choose.
The good news is that those are one-time costs, and in most cases you will own the equipment. Once your system is installed and operational, there are monthly fees to consider.
You have a lot of control over your monthly security system cost, as packages vary significantly depending on the services, features and levels of monitoring you select. There are basic plans available from reputable companies for as little as $20 per month.
However, depending on your needs and budget, there are more advanced packages that include things like live, round-the-clock monitoring or regular security patrols that can cost several hundred dollars or more per month.
