THE ALLIANCE DIFFERENCE
Niagara’s Local Security Experts Since 1985
When it comes to protecting your home, local knowledge matters. Since 1985, Alliance Security has been the Niagara region's dedicated partner in safety. Unlike national call centres that treat you like a number, we are your neighbours in St. Catharines, Welland and Niagara Falls.
Professional Craftsmanship: We believe true security starts with a professional installation. Our in-house, non-commissioned technicians take the time to understand your property's unique layout—whether it’s a historic home in Niagara-on-the-Lake or a new build in Thorold. We ensure clean cabling, optimal camera and security sensor placements for total coverage and we don't leave until you feel completely comfortable using your new system.
FLEXIBLE INSTALLATION OPTIONS
Find the Right Security Solution for Your Home
Already Have A Security Alarm System?
Don't replace equipment that isn't broken. We specialize in taking over monitoring for existing DSC, Honeywell, and Paradox panels. We can often reuse your existing wired sensors while upgrading just the keypad and panel—giving you a modern smart system without the cost of a full rewire.
Keep Your Hardwiring: We test and reuse your existing door and window contacts to save you money on installation.
Upgrade the Brain: We replace outdated panels with a modern smart hub, giving you instant smartphone access and LTE reliability.
Seamless Transition: We handle the upgrade and testing to ensure a smooth switch to our local monitoring.
Need A New Alarm System?
Whether you are building, renovating, or securing an existing home, we design modern systems that fit your lifestyle. Enjoy top-tier wireless security using encrypted PowerG technology, providing massive range and reliability without the need for messy construction or drilling.
Clean Installation: No drilling or unsightly wires running along baseboards.
Reliable Wireless Tech: We use long-range, encrypted sensors (PowerG) for superior reliability.
Flexible Protection: Easily add sensors to detached garages, sheds, or hard-to-reach windows.
