With the rise in home burglaries, installing a home alarm or security system might give you peace of mind. Though you might be intimidated by the cost of installing a home security system, there are actually different types of systems at many different price points.

Types of Home Alarm Systems

There are two primary decisions to make when it comes to home security. Do you want your system to be wired or wireless, and do you want a system that is monitored by an outside company or unmonitored?

Hardwired vs. Wireless Systems

Hardwired systems have sensors physically wired into the walls at entry points and throughout your home that are wired into a central control station. Wireless systems use wireless sensors that send signals back to the control panel. A wireless system is a simpler and less expensive installation job, but it requires being conscientious about battery replacements.

Monitored vs. Unmonitored

In a monitored home security system, a signal is sent to a notification center outside your home where help can be dispatched to your location. In an unmonitored system an alarm sounds, but you would rely on neighbors calling the police if you weren't home or the sound scaring away the intruder. A monitored system will cost more with an additional monthly fee. However, these systems come with a guarantee that help will be dispatched within a short time frame.

Home Alarm System Components

The cost of your system is also affected by the number and sophistication of your components. Home alarm systems can have central control panels, keypads, sensors, and alarms. There are a variety of prices depending on the complexity and quality of these components and whether or not they are wired or wireless.


Most professional installers will charge an hourly rate for installing your alarm system, although some may have a flat rate for each type of system. Traditionally, a wireless system is simpler and faster to install and a wired system more time-consuming to install less expensive components.
