I was binge-watching Batman the other day and couldn’t help but notice—our city has a little Gotham vibe of its own. From trespassing to break-ins to good old-fashioned porch piracy, crime finds its way into everyday life (let’s hope not in ours, though).
The bad news? We don’t have a caped crusader swooping in to handle it. The good news? We’ve got the next best thing—cameras, smart detection tech, and security solutions that actually work.
Well, we know how overwhelming it can be to find the right one. The good news? Our team did the legwork for you! We reviewed the best alarm systems in Ottawa, so you can protect your home or business, sleep easier, and have solid evidence on hand if the unexpected happens.
Read on to take the first step in protecting your peace of mind!
How much do alarm systems cost in Ottawa?
Alarm systems in Ottawa usually cost $250-$400 for basic equipment and installation, while advanced setups with smart features can reach $1,000 or more. Monthly monitoring fees typically range from $20-$50.
1. Onvision Security Inc.

Address: 343 Preston St 11th Floor
Phone: +1 613-260-8119
Business hours: Monday to Friday: 9 AM – 6 PM
Onvision Security Inc. covers a wide range of services besides alarm systems. They can also offer access control, intercom systems, surveillance, and more, which means you can take care of the “security” needs in one place.
Their hard-wired installation option is also a plus since it reduces risks from wireless jamming or signal interference, especially for places where signal drop is a concern.
Another thing worth highlighting is that their surveillance packages typically include remote monitoring of live feeds or playback via app without extra costs.
Speaking of packages, we appreciate how customizable and scalable they are. You can expect them to have suitable systems for homes, businesses, and large properties.
And users or clients get to benefit from 4K cameras, night vision, etc. We like how clear the quality is; you can identify things like faces and license plates, which can come in handy for investigations or insurance claims.
Lastly, it’s great that they offer free on-site quotes or consultations. Just note that they’re closed on weekends.
Outstanding service from start to finish
“Outstanding service from start to finish. Hussein was responsive, knowledgeable, and genuinely cared about getting everything right. The installation was smooth, and the system works perfectly. You can tell this team takes pride in their work. Onvision is a company you can trust.”

2. Comcon Security Systems

Address: 188 Grandview Rd, Nepean
Phone: +1 613-800-8000
Business hours: Monday to Sunday: 8 AM – 10 PM
With over 30 years of experience, Comcon Security Systems has been providing residential and commercial alarms, video surveillance, intercoms, metal detectors, fire protection, access control, and other security services. Their experience also means they’re used to local codes and laws.
We like that they offer modern smart alarm monitoring, like systems that work over VOIP and smart-home integrations. This is a win for those who prioritize mobile controls, remote monitoring, or home automation.
For those who want “security” over their security, we found that COMCON has a false alarm policy and warranty. This basically helps protect you from equipment failures, and the false alarm policy helps avoid fees or penalties in case of accidental triggers.
But we do think some of their services are on the pricier side, especially if your property requires something complex. On the bright side, you can opt to lease or purchase their systems and services, giving clients more flexibility.

3. Abav Security

Address: 2450 Lancaster Rd
Phone: +1 613-738-7707
Business hours: Monday to Friday: 9 AM – 5 PM
ABAV Security or Audio, Video & Security specializes in offering customized alarm systems, and not just one-size-fits-all packages. They emphasize providing solutions that match your space, needs, and lifestyle.
As an extension to their name, their services also include video, music distribution, theatre systems, and cabling, which is great if you want multi-system integration along with your alarms.
On top of this, we also love that you can go for automation, video surveillance, and integration with home/office technology. If you want lighting control, door locks, and more, then this is a game-changer.
It’s also worth mentioning that they’re an authorized dealer for Alarm.com, giving clients access to modern, app-enabled security tech, like remote arming/disarming, status alerts, motion detection, and viewing.
Lastly, while they do offer free estimates so you can get a sense of cost and design, keep in mind that they’re closed on weekends.

4. RedFlag Security

Address: 207 Bayswater Ave
Phone: +1 613-799-1188
Business hours: Monday to Friday: 9 AM – 5 PM
What we like most about RedFlag Security’s Alarm Systems is that they have a wide range of detection features like wired and wireless systems, door/window sensors, motion detectors, glass-break sensors, panic buttons, smoke/CO detectors, and more.
Having many features, we find it handy that their systems also support smart home integration, such as voice control, app control, and remote monitoring.
It’s also reassuring to know that they provide a lifetime warranty on new alarm systems. This means hardware defects or failures are less of a worry long-term.
Just a heads-up, though—their alarm monitoring starts at $15.95/month, and availing this will get you a free basic alarm system plus professional installation. In other words, it’s more of a subscription-based service for monitoring rather than buying the system itself, which some may not want.
Their packages also offer 24/7 professional monitoring, so there’s always someone watching over your property, even when you’re not.
Great service
“Good knowledge. Good product. Great customer service. I reached out to multiple companies and they were the only ones who even responded. Thanks for the great service!”
Ryan Steiner, Google Review
Everything was set up correctly
“I’ve received timely and relevant responses from the quote process onward. Our technician was polite and neat, he stayed longer than usual to make sure everything was set up correctly. I’ve compared the prices to mainstream and more local security companies and RedFlag was by far the most cost effective. Highly recommend.”

5. Alliance Security Systems of Ottawa

Address: 872 River Rd
Phone: +1 613-860-0396
Business hours: Monday to Friday: 9 AM – 5 PM
We love that Alliance Security Systems of Ottawa (Allsecure) offers round-the-clock monitoring through trained professionals, which means your alarms are being watched even when you’re asleep or away.
They also provide interactive control over your security system, including smart features like app notifications and remote disarming/arming. Having access to your systems via your phone is a big plus.
Beyond alarms for break-ins, you can also rely on them for early warning detection for fire, gas, leaks, flooding, furnace failures, and more. We like that this broad scope allows clients to protect their property more comprehensively.
The catch? We noticed that some related fees add up and make some systems pricier. And we noticed that cancellation fees can be expensive.
Here’s the silver lining: if you have an existing alarm system, they offer free inspection and takeover service, which is ideal if you’re switching providers and don’t want to mess up your property by ripping out and replacing everything.
A pleasure to work with
“Terrill was a pleasure to work with, and did a great assessment on our home. Denis installed our system and walked us through every detail of the app as well. Paula was fantastic in her responsiveness to all my questions. Fantastic customer service.”
