Google reviewWe found Knightwatch via ChatGPT when Bell sold their home monitoring business. It recommended them because they met our needs - a company with a strong reputation that would answer when we called and didn’t keep making us “upgrade” our equipment. We got so much more. This is a family business that doesn’t lock you into a contract. They earn your business monthly. I would highly recommend them.
Google reviewWe’ve used Knightwatch for over 20 years. Adam is a great guy to deal with, and extremely knowledgeable. We’ve always had great service with them and can’t speak highly enough of them.
Google reviewWe have been with Knightwatch for many years and can’t imagine a more professional, responsive company. Noah came to our house to troubleshoot and regular maintenance. He was a complete pleasure! He went out of his way to make sure we were 100% satisfied with the service before he left. Everybody at this company goes the extra mile to make sure customers are happy and their properties well protected.
Google reviewWe had the pleasure of having Adam work on our alarm system. He is beyond professional, knowledgeable and courteous at the same time. He truly cares about his clients and will go to extra mile to ensure that his clients are satisfied with their needs. We HIGHLY recommend Knight Watch Security as the only contractor you will ever need.
Google reviewMy experience with Knightwatch has only ever been excellent. They provided me with a variety of security measures and protection and I am grateful for their personalized service and approach. I would not hesitate to engage in their services if I were a prospective customer.
Google reviewHad Noah from Knightwatch pre wire my new system today. Clean, professional service second to none. I highly recommend Knightwatch for both your residential or commercial security needs.

Home and business security FAQs
What does a home security system cost in Toronto?
It depends on the size of the property, how many entry points need protecting, whether you’re taking over existing equipment, and which monitoring options you choose. The on-site evaluation and quotation are free, so you’ll get an exact price before committing. Request a quote.
Can I switch alarm companies and keep my existing equipment?
Often, yes. Many existing panels and sensors can be reprogrammed for Knightwatch monitoring; compatibility depends on the equipment and certain conditions apply. Takeovers of compatible equipment are currently free (additional parts extra). See home alarm takeovers, or switching guides for Bell & API Alarm and TELUS & ADT customers.
Do I have to sign a long-term contract?
No. Knightwatch monitoring has no annual contract — we earn your business every month.
What happens when my alarm goes off?
The signal goes to our 24/7 monitoring department. Operators follow the dispatch instructions on your account — contacting you and your emergency contacts and dispatching emergency services or a private guard when required. How monitoring works.
Wired or wireless — which alarm system is better?
Both are reliable when installed properly. Hardwired suits new builds and renovations; wireless suits finished homes. Many systems combine both. Read hardwired vs. wireless alarms.
Do security cameras need a monthly subscription?
Our camera systems record locally to a recorder on site, so viewing and playback from your phone don’t depend on a cloud subscription. Home security cameras.
Can my alarm detect fire, carbon monoxide and floods?
Yes. Monitored smoke, heat, CO, water and temperature sensors alert the monitoring station even when nobody is home. Life-safety monitoring.
Which areas does Knightwatch serve?
Toronto and the Greater Toronto Area — 29 featured service areas from Oakville to Oshawa and north to Newmarket — plus properties up to about two hours away, including cottages. See all service areas.
