Average Costs of Installing a Home Security System

While many homeowners are eager to get a specific number for the cost of installing a home security system, the total cost can fluctuate wildly depending on the size of your home, the scope of the system and the types of components you include. Installing a large password-protected security gate, for example, will be more expensive than setting up surveillance cameras at the front door. Average costs for an alarm system come in around $887, installing surveillance cameras is roughly $1,923 and installing a security gate comes in between $4,203 and $5,831. 

Components to Consider in a Security System

There are a number of different elements that might be included in the perfect home security system for your family. A standard alarm system is the most common option, and you can choose between a wired and wireless system. Surveillance cameras can be an extra cost, but the addition may give you peace of mind and is popular among those with children or lots of staff coming and going on a regular basis. The biggest expense may be including a security gate, but the addition of this investment can be significant in terms of discouraging intruders.

Ongoing Costs of Security Systems

Keep in mind that beyond installation, many of these security systems for the home include monthly expenses. Aside from the energy consumption that may increase your electricity bills, monitored systems tend to come with a monthly subscription cost. While expensive, this may be a key to feeling more secure in your home at all times.
