3 steps to choosing a home security system

Choosing the best security system for your family and home depends on your primary safety concerns, selected coverage area, desired features and budget.

1. Assess your home security needs

Home security systems can cover properties from 1,000 to 4,000 square feet with six to 20 entry points (doors and windows). For homes of 2,500 square feet with six entry points, systems should support at least 12 sensors and multiple camera placements. Homes of 3,000 square feet generally require systems that can support 16 sensors, multiple camera zones and sufficient signal strength.

How to define your home security needs

Use the list below to determine your home’s security needs:

  • List your primary security concerns: Home security systems commonly protect the interior, exterior or both against burglary, fire, environmental hazards and package theft.
  • Note your home’s size and number of entry points: Don’t underestimate the impact of home layout, square footage and entry points for the number of cameras and sensors needed for full coverage. Multi-story homes often require additional sensors per level to ensure wireless signal reach.
  • Identify your desired features and components: Decide if you want to add cameras, sensors, smart locks and environmental detectors to your new home security system, and, if so, how many.
  • Set a preliminary budget range: Equipment and installation account for the bulk of a home security system’s costs, while professional monitoring fees, required municipal permits and maintenance can also increase the total.
  • Explore the potential for smart device integration: Ask prospective home security companies whether their systems integrate with Google Home, Amazon Alexa or Apple Home.
  • Consider accessibility concerns: Households with children, disabled or older residents benefit from accessible keypads with large, tactile controls, panic buttons and voice alerts. Overlooking accessibility needs can lead to costly retrofits or unsafe gaps in coverage.

If you own a detached garage or shed, select a home security system with up to 500 feet of extended wireless range. Consult any homeowners association (HOA) rules and regulations before purchasing equipment. If you rent, choose wireless, no-drill and contract-free options to protect your security deposit and avoid being locked into protecting a space you no longer inhabit.

2. Compare security system features

When evaluating home security systems, compare your options based on installation, monitoring capabilities and contract terms. While opting for the cheapest home security system available may help you protect your home for less, the second most affordable option might be worth the extra money.

How to evaluate home security system features

The type and number of required features available—including cameras, sensors, smart locks and environmental detectors—depends on the following:

  • DIY vs. professional installation: Most professional installations can take between two and six hours, compared to 30 to 120 minutes for do-it-yourself (DIY), which can be just as reliable for many homes.
  • Professional monitoring vs. self-monitoring: Choose professional monitoring for 24/7 emergency response times of 60 seconds or less. Self-monitoring response times depend on reliable smartphone access.
  • Wired vs. wireless system: Wired systems offer better reliability for homes with thick walls and multiple stories, but installation is invasive and takes twice as long as wireless. However, wireless systems are more vulnerable to Wi-Fi outages.
  • Contract requirements: Compare contracts based on commitment (month-to-month or term) and watch for hidden monitoring fees. A self-installed, wireless and contract-free system offers the most flexibility.

Confirm home security system compatibility with your current Wi-Fi bandwidth. Most systems require at least 2 megabits per second (Mbps) per camera for high-definition (HD) streaming and support up to 32 cameras or sensors. Test the mobile app user experience for easy navigation and to automate select options.

How to choose features for burglary, fire and safety needs

If burglary is your top concern, prioritize home security systems that incorporate mobile alerts and loud sirens of at least 100 decibels (dB). Position exterior cameras and sensors at points of entry, including doors and windows, as well as motion and glass break detectors. Install reinforced or smart locks.

To combat fire or carbon monoxide, home security systems must be certified to UL 985 (smoke detection) and UL 2034 (carbon monoxide detection). The best systems integrate these detectors with audible alarm systems and central notification.

Don’t overlook environmental sensors such as water leak sensors, temperature alerts and flood sensors. The average water and fire damage claim totals $10,000 to $25,000 per incident, often exceeding theft claims.

For basic monitoring of children and pets, indoor cameras, two-way audio and security app notifications suffice. Zone masking can also help track pet movement and prevent false alarms.

3. Review contracts, pricing and legal factors before purchase

One-time and recurring fees comprise the bulk of home security system costs. When reviewing home security system contracts, read the fine print to determine how providers handle equipment ownership, false-alarm policies and early termination. Ask whether providers offer price-lock guarantees that protect you from unexpected rate hikes after the first year.

How to budget for a home security system

Contract length influences the total cost of a home security system. Selecting between a month-to-month plan and a term contract (12 to 36 months) will determine your minimum investment for home security. Maintenance can also add to the bill, which primarily consists of the following:

  • Equipment: $200 to $2,500 or more
  • Installation: Free (DIY) or $500 (professional)
  • Monitoring: $10 to $60 per month
  • Permitting: $0 (not required) or $25 to $100 per year (required)
  • Cancellation: $150 to $700

Some HOAs ban visible security cameras or require approval for exterior devices. Restrictions can also extend to signage and alarms. False alarms will also incur a $50 to $300 fine per incident in certain cities.

No-contract, portable systems often serve those who move frequently best. If your HOA restricts you, select discreet or indoor-only cameras. Always request a sample contract before you buy to avoid cancellation penalties and hidden fees.

Set up, connect and customize your home security system

Most smart home integrations require a 2.4 (gigahertz) GHz Wi-Fi network. Place cameras at 7- to 9-feet high for optimal coverage and privacy. Check device compatibility and test all components before finalizing installation to avoid blind spots.

Common integration issues include Wi-Fi conflicts and device recognition. Follow the app or platform instructions for resetting devices and checking firmware. If this troubleshooting doesn’t solve the problem, contact support.

How to install and integrate a home security system

DIY home security system installation takes between 30 minutes and an hour and a half. It consists of unboxing the equipment, placing cameras and sensors where desired, connecting the hub and testing the system. At two to six hours, professional installation involves scheduling the install, performing a walkthrough with a technician and system testing upon completion.

Here are additional home security integration and accessibility tips:

  • Confirm Wi-Fi speed (minimum 10 Mbps recommended for multiple cameras).
  • Download the system’s mobile app before setup.
  • Enable two-factor or multi-factor authentication for security.
  • Create user profiles for all household members and involve them in setup and training.
  • Adjust notification and alarm settings for accessibility needs.
  • Connect devices to Google Home, Alexa or Apple Home using manufacturer guidelines.

If someone in your home has low vision, opt for systems with audible prompts and high-contrast displays. For accessibility, prioritize systems with large, tactile buttons and voice control. Select systems certified for Google Assistant or Amazon Alexa offer voice control features.

Maintain, upgrade and troubleshoot your security system

Even the best home security systems require routine maintenance and periodic updating. Use the tips below to ensure your system remains reliable and responsive:

  • Test alarms and sensors monthly and after major home changes.
  • Clean camera lenses and sensors.
  • Replace batteries every six to 12 months (wireless) or as recommended.
  • Update firmware/software quarterly.
  • Review and update user codes and permissions.
  • Schedule an annual professional checkup (if available).
  • Document and resolve any false alarms.

Keep a log of maintenance and incidents for warranty and insurance purposes. Document false alarms, as three or more annually can result in municipal fines.

The U.S. Fire Administration recommends installing interconnected smoke alarms so that when one sounds, they all sound. It’s also smart to install an alarm inside every bedroom, outside each separate sleeping area, and on each level of the home for optimal safety.
