How to choose a home security system

How much does a home security system cost?

A basic home security system costs about $32 per month. Consider the cost of home security system installation, activation fees and monthly alarm monitoring fees before choosing a home alarm company. Adding more security cameras and sensors will cost extra too. Consumers report paying between $500-$1500 to get their residential alarm systems fully up and running.

  • Burglar alarm installation and activation costs: Installation is either done by a professional or can be a do-it-yourself (DIY) project; some companies let you choose an installation method, while others offer only one option. Professionally installed alarm systems can cost $100-$500+; DIY is free, but it requires more of your time.
  • Security system monitoring services: Subscription home security systems–home alarms monitored 24/7 by outside companies–carry a monthly fee, usually in the $20-$60 range.
  • Home security equipment costs: You'll likely catch a price break on equipment in exchange for signing a contract to have your alarm system monitored. If you purchase a system outright, expect to pay $100+ for a basic system and $500+ for top-of-the-line equipment.
  • Municipal fees for alarm permits: Some cities charge a yearly permit fee, often less than $50, to respond to emergency calls triggered by monitored home security systems. Even in the event of a false alarm, police will still respond which can drain police resources over time. The permit fee helps offset this cost. Permit fees are not collected by the alarm companies, so it is important for homeowners to remember to pay this fee on their own.

Can I get a home security system with no contract?

Yes, some alarm companies offer no-contract security systems when you buy the equipment outright or agree to pay a slightly higher monthly rate.

Many home security companies offer discounted equipment in exchange for a signed contract, similar to how your cell phone company offers discounts on phones when customers sign up for a new plan. Some alarm system contracts are more flexible than others, so read through the contract terms (and online reviews) before signing on the dotted line.

  • Contract length: Most alarm system contracts are for 2-3 year terms. Many allow for cancellation within the first 2-4 weeks of the contract's term.
  • Contact terms: Pay special attention to a contract's fine print. Look for information about equipment warranties, cancellation clauses, service call fees, etc.
  • Contract portability: Many alarm system companies make it easy to transfer your equipment to a new home, so if there's a chance you'll move during your contract, check first to confirm relocation possibilities.

Who installs home security systems?

There are two basic installation options you can choose: professional installation and DIY. If you're thinking about purchasing a wireless home security system, you'll usually have the option to set it up yourself or hire a professional to do it for you. Most hardwired systems, however, require professional installation.

  • Professionally installed by the home alarm company: Many complex alarm systems, usually those that are hardwired into a home, require professional installation. This usually carries a hefty cost ($200-$500+), although some companies offer discount installation.
  • DIY home alarm system: Do-it-yourself security systems are generally easy to install, often requiring just a few hours to read the manual and place your sensors.
  • Third-party professional installation: If you purchase a DIY system but aren't a DIYer, you can hire a local handy person to do your installation at an hourly rate.

How are home alarm systems monitored?

When you opt for professional monitoring, home alarm companies offer monthly monitoring via three types of connection: internet (broadband/VOIP), phone line or cellular service.

  • Internet: Monitoring via the internet is inexpensive, but be aware that if you have an internet outage (or a power outage that disables your modem), you will be cut off from monitoring.
  • Phone line: You can use your home phone line (landline) to connect with your alarm monitoring company. Be aware that if a burglar cuts your phone line, your system will not work. If your phone line is fiber optic, you’ll need a battery backup system to power your alarm if the power goes out.
  • Cellular: Monitoring via cell phone connection is a good option for those without a landline. This service will remain available even in the event of a power or Internet outage.

What features can you add to an alarm system?

Basic systems are just that: basic. You'll most likely want to expand your system to meet your home's specifications–number of windows and doors, outdoor lighting requirements, etc.–so look for a company with the add-on equipment and features that suit your needs.

  • Home security equipment: Control panels, security cameras, door sensors, smoke detectors and motion sensors come standard with most basic home security packages. Some alarm companies offer custom add-ons like key fobs, panic buttons, doorbell cameras, touch-screen panels and hands-free voice control. Equipment offerings vary greatly by company, so choose wisely before signing a contract.
  • Monthly monitoring plans: Monthly alarm monitoring plans can range from bargain-basement monitoring via an internet connection to all the bells and whistles, including smoke detection, medical monitoring and home automation.
  • Service upgrades & downgrades: Lifestyle changes may require variations in your home security needs; check with your company about the ease of adding (or removing) services or switching monthly plans mid-contract.

What remote access is available for alarm systems?

Many home security companies offer remote access to the system via their website and mobile apps. You can use the app to control your security system access your security camera feeds and manage an array of home automation functions.

  • Website access: Many companies let you sign in to your home security account online to have easy access to your system from wherever you're at.
  • Smartphone apps: If the alarm company has a mobile app, you'll be able to monitor your home while you’re away. Standard data rates will apply.

How much do you save on homeowners insurance with an alarm system?

Many home insurance providers offer discounts (even up to 20 percent) for homes with monitored alarm systems. So if you pay $1,000 for your homeowners insurance and get a 10 percent discount, you’ll save $100 each year simply for having a monitored home security system.

    Types of security system companies

    Smart home security systems

    Smart home security systems focus on convenience and are remotely controlled using a smartphone and an app. They are highly customizable in terms of installation, type of surveillance and cost. Smart home security systems alert homeowners in emergencies as well as monitor and control everyday activities like turning off the lights and locking the doors.

    Wireless home security systems

    Wireless home security systems are minimally invasive in terms of installation. They use a series of battery-powered devices such as motion detectors and door and window sensors. This type of home alarm monitoring does not require a landline as it communicates via radio and cellular technology.

    Wired security system

    Wired security systems require an active landline and reside within the structure of the home. The system’s sensors are physically connected to the control panel through wires within the walls. Installing a wired security system will require some drilling and modification.

    Monitored security system

    Monitored security systems send notification in the event of an emergency. This type of security system can be self-monitored or with the use of a home monitoring company. Depending on the system type, the homeowner or the authorities will be contacted.

    Unmonitored security system

    Unmonitored security systems do not notify the homeowner or the authorities in the event of an emergency. When an intrusion is detected, sirens sound but it is up to those present to take the necessary next steps.

    People who should consider a home alarm


    Homeowners who are interested in home security to protect their real estate, belongings and family will often want a robust system with all the bells and whistles.


    Renters or homeowners who plan to move in the next 2-3 years, and therefore are not interested in long-term contracts or permanent equipment should consider wireless portable systems with short-term or no contracts.

    Hands-off consumers

    Consumers who want a fix-it-and-forget-it security solution that keeps their home safe with very little input required generally prefer systems with excellent monitoring.


    DIY consumers are handy and capable of completing system installations. They're often willing to exchange certain responsibilities for cost savings.

    Tech-savvy shoppers

    These homeowners and renters are interested in security with a technological component. They want systems with remote access, web-based portals, mobile apps and other tech solutions that allow them to tweak, manipulate and monitor their home security system.
