Security Level

As depicted in the table above, the main factor affecting the cost of home security systems is the level of security sought-after. For example, a video doorbell (ring camera) will be much cheaper than a wireless alarm system. 

Size of Home

The home’s square footage will also be an influential factor in home security system installation costs. A bigger home means more equipment—whether sensors, security cameras, video surveillance, or other devices—leading to a significant increase in overall costs.

Monthly Home Monitoring Service Fees

Investing in professional home security system monitoring is beneficial, offering around-the-clock support and monitoring. In the event of an incident, surveillance personnel can assess the alarms, contact law enforcement, and inform other concerned individuals. However, this includes monthly fees and said rates are likely to vary based on the security company.

Brand and Quality

Leading brands or high-quality systems are typically associated with higher price tags. Purchasing a system from a reputable brand can deliver better performances, longer-lasting results, and access to customer service, ensuring the purchased or leased security system works effectively over time. 

How Much Does It Cost on Average to Install a Smart Home Surveillance System?

Alarm systems vary significantly cost-wise based on their features and their level of sophistication. Here’s an overview of the different options available, from budget-friendly solutions to high-end systems.

Budget-Friendly Options

Front Door Sensor

A front door sensor is a cost-effective device that’s easy to install and triggers an alarm when a door swings open. These sensors provide paramount protection for your front door and are often retailed at very affordable prices. 

Motion Sensor

Motion sensors are affordable options, detecting movements within predetermined areas. It takes into account the size of the room and detects sudden changes, such as an abnormal temperature variation, to spot an aminal or human presence. They can be installed inside or outside, and when motion is detected, an alarm is triggered, providing additional home security at an affordable price. 

Standard Product Buying Guide

Door and Window Sensor

Door and window sensors are standard devices that surveil the opening and closing of entryways and windows. They’re rather affordable and easy to install, making for must-haves to strengthen at-home security.

Alarm System Pad with Chime

A pressure sensor mat with an alarm and doorbell is a standard product activated when weight is applied. This device can be placed on your front stoop or in hot spots and is usually priced affordably while providing reliable protection against break-ins.

High-End Options

Glass Break Detector

A glass break detector or sensor is a high-end device that’s paired with acoustic sensors designed to detect the sound of breaking glass. Made for security-conscious homeowners, these costly devices provide proactive protection against break-ins and vandalism. 

Complete Wireless Home Security System 

A complete home security alarm system with a wireless connection is a high-end solution that includes several devices, such as security cameras, sensors, and alarms. Albeit more expensive than basic options, it provides all-encompassing protection and unmatched peace of mind, making for a worthwhile investment for those seeking effective home security.

What Are the Additional Costs of a Good Home Security System?

Professional Installation Fees

Depending on the system selected, you may very likely be able to carry out a quick and easy DIY installation. You won’t likely need any help for a straightforward ring camera. However, for more complex systems, especially those requiring wiring around the whole house—which may involve drilling some holes and pulling cables—hiring a professional installer comes highly recommended, yet will incur additional costs. 

Maintenance Fees

The batteries run out, surveillance cameras can break down, storage systems can max out, and sensors can malfunction. Much like all electronic devices, home security systems require routine maintenance. As such, when installing a home security system, bear in mind that you’ll need to carry out select routine maintenance procedures. 

Alarm Permit Fees

Before installing a security system, it’s important to verify whether you’ll need permits. Depending on your area of residence and the type of system you plan on installing—such as video surveillance cameras or alarm systems—local regulations may mandate permits, which are often tied to fees. As such, when planning on installing a security system, review your local regulations to understand permit requirements and factor in future expenses to keep things running smoothly. 

Cancellation Fees

If you lease your security equipment, bear in mind that cancellation fees may apply if you decide to bring your contract to a close, underscoring the importance of reading the fine print and lease agreement closely. By opting for a commitment-free contract, you can cancel at any time, at no extra cost. However, bear in mind that monthly fees can increase at any time.

FAQ

What is a house security system?

A home security system is a grouping of monitoring technologies designed to protect homes and their occupants. It serves to protect from burglaries by detecting possible break-ins. A security system typically includes a wall-mounted alarm control panel, installed near the front door, as well as motion sensors, using infrared technology to detect the presence of individuals through body heat. 

However, over time, traditional control panels were replaced by mobile applications accessible via smartphones. These cutting-edge technologies allow homeowners to remain connected to their homes 24h/7. If your system is equipped with security cameras, you can monitor your home in real-time and, in the event of a burglary, provide law enforcement with valuable footage to streamline their investigation. 

What is the top-rated home security system?

After more than 100 hours of testing, CNET determined that the SimpliSafe home security system was the safest in the business and their top choice for consumers in 2024. If you’re looking for a security system with 24h/7 professional monitoring in Canada, ecobee Home Security is your best bet.

What is the average cost of an ADT security system?

With ADT, it really depends on the package you're looking to subscribe to, whether that's the outdoor video, front door protection, or total safety package. Note that their outdoor video monitoring package doesn't include carbon monoxide detection, motion detection, or water and temperature detection. However, all three are equipped with a 24-hour battery backup in case of a power outage. Bear in mind that upfront costs (equipment and installation) can be quite costly, but monthly fees can be quite budget-friendly, depending on the subscription that best fits your needs and whether you've opted for professional monitoring. 

What are the advantages of a home security system?

  • Promotes a sense of security.

  • Budget-friendly prices and a broad range of available products and models.

  • An alarm is triggered in the event of a break-in.

  • The mere display of a security system warning sticker is in itself a major deterrent to would-be burglars or thieves.

What is a home security system with remote monitoring?

A security system linked to a remote monitoring centre is a security device that, in the event of a break-in, emergency, or threat, will automatically alert the remote surveillance centre. Said remote professional monitoring base station is often managed by a security firm that receives incoming warning alarms 24/7. When an alarm is triggered, remote monitoring operators can verify the threat and, if necessary, contact emergency services or law enforcement for immediate response. This type of system provides continuous surveillance and a quick response time in case a problem arises, increasing home or business security.

Should you buy or lease your home security system?

When hiring a company to protect your home, the first choice you’ll be asked to make is whether you want to buy or lease a security system. It’s important to mention that there are upsides and drawbacks to consider with either option.

Indeed, when purchasing an alarm system, the installation costs are higher, yet the monthly fee for connecting your system to a remote monitoring centre will be lower. Should you choose to lease your security system, installation costs will be very low, yet monthly fees will be much higher. Overall, it’s a matter of investment, and asking yourself the right questions is of utmost importance to make the right decision. 

The Office de la protection du consommateur (consumer protection) advises to asses one’s needs and inquiring about the different types of contracts available. Security companies offer month-to-month contracts or longer-term commitment (or commitment-free) contracts. Should you choose to commit for a set period, the fees will not increase for said time period.
