ALREADY HAVE A SECURITY ALARM SYSTEM?

Don't be locked into a system that doesn't work for you. We specialize in alarm monitoring takeovers for DSC, Honeywell, and Qolsys panels. We can often reuse your existing sensors and wiring while upgrading just the main control unit—giving you modern app control and local Niagara monitoring without the cost of a full rewire.

We upgrade systems originally installed by national providers like Bell, Rogers, Telus, and ADT, as well as local alarm companies, utilizing your existing DSC, Honeywell, or Qolsys infrastructure.

 Trustindex verifies that the original source of the review is Google. From the very beginning my experience with Alliance has been exceptional.  They scheduled my appointment quickly. Kent (sales) was informative, and gave me a great price.  My installation was done when I wanted without any problems.  Mitch (the technician) was also informative, knowledgeable and thorough.  Also, the entire staff is friendly and highly accessible.  I would recommend Alliance Security Niagara without hesitation. Lisa

 Trustindex verifies that the original source of the review is Google. The owners and staff are always courteous and very focused on quality customer service. I recently interacted with the owner of the company and one of the IT technicians. Both of them were excellent, as usual, in helping to resolve/answer the questions we had and assist us with upgrades to our alarm equipment. Thank you, Alliance Security Niagara!

 Trustindex verifies that the original source of the review is Google. Mitch who installed my system was amazing. He patiently explained how to operate my new system (my old one was 30 years old!) and made modifications based on my individual needs. I am a senior and not that tech savvy, so having Mitch patiently walk me through the Alliance app was greatly appreciated. Other security service providers prior to this did not offered this level of attention to detail. I look forward to using my new system. Thanks Mitch and Alliance!
