Depending on the company, installation of a home security system can be free. Most companies run special promotions often throughout the year. You can also install an unmonitored system yourself to protect your family. According to CostHelper, in 2011 installation can range from $50 to $300 depending on your package. More elaborate systems can cost more than $1,500.
Both monitored and unmonitored systems offer different options to strengthen the system. Most offer door and window sensors, while some have motion detectors for inside the home, cameras, recordable video, additional control panels and sirens. Extra equipment costs can vary between companies.
Monitoring can be done through a broadband connection, cellular air waves, land line telephone or two-way land line telephone. The monthly bill can range from $8.99 to $42.99 per month. The cellular and two-way land line monitoring can also incur an additional equipment cost that would not be covered in a package installation.
