Smart Home Security Package Inclusions and Costs

Before choosing a professional monitoring and equipment package, carefully review the inclusions to ensure they meet your needs. You’ll get the best value for your money with a full-perimeter, comprehensive home security system that comes with the following: 

Motion and Entry Sensors Cost

Door and window sensors typically cost between $20 and $60. Adding a motion detector for each one drives the price by $30 to $100 more per unit. Note that you need multiple sensors to cover all entry points.

Surveillance Cameras

Indoor cameras typically cost between $100 and $200, while outdoor security cameras with weather protection are slightly pricier, ranging from $150 to $300. The more expensive models often come with night vision and smart alerts. For video doorbell cameras, you can score HD ones for $150 to $250.

Control Panels, Hubs, and Keypads

Primary control panels generally cost $100 to $300, and extra keypads for back entrances or bedrooms can add $50 to $150 each. Buying them in bundled packages gives you better deals.

Environmental Sensors

Environmental sensors help you catch hazards early before they cause damage. These types of equipment, each with its own specific purpose, come at similar price points:



  • Smoke alarms typically range between $40 and $100
  • Carbon monoxide (CO) detectors cost $50 to $150
  • Flood leak sensors cost $30 to $80 each
  • Temperature sensors typically cost between $25 and $60

Home Security System Installation Costs

The installation fee that professionals charge depends less on the cost of equipment and more on the labour involved. They account for home layout, wiring routes, and device placement. A complex project that requires retrofitting would cost significantly more than an easy DIY installation setup. 

Wired vs. Wireless Equipment

Wired systems are more expensive to install because they require drilling and cable routing. Installing a wired home security camera and alarm system may require electrical upgrades to the affected walls.


Although expensive, they’re generally more reliable because they’re less susceptible to interference, power loss, or signal jamming. They provide higher-quality security monitoring footage.


Alternatively, wireless third-party devices are easier to install and set up, but they require constant monitoring and charging, or regular battery replacement. Forgetting may come at the expense of security.

Number of Devices Being Installed

Every additional door sensor, window sensor, and other security and smart home integrations you add will increase your setup time. As a result, your technicians would have to charge more.


It’s common for larger homes with multiple entry points to pay three or four times more than those who live in small apartment units. See how many entry points you’ll need to cover to get a rough estimate.

Placement Difficulty

Placement is also a critical factor to consider. It’s more expensive to set up systems in hard-to-reach places, such as high ceilings, exterior walls, and roof eaves. Likewise, outdoor cameras may need weatherproofing seals, conduit, or ladder work, which adds to the total cost.

Removing or Replacing Old Equipment

Note that you may incur additional costs if your technicians need to remove professionally installed systems. Safely disconnecting old panels, wiring, or sensors requires considerable effort. 

Smart Devices and Smart Home Compatibility

Syncing different security and smart home devices (e.g., Alexa and Google) requires technical expertise, especially if you want everything to work under one remote control. Automation routines and mobile app setup can extend installation sessions.
