Smart Management
Control multiple sites, manage user codes, and view system status instantly from your phone.
ADVANCED DETECTION TECHNOLOGY
Next-Generation Hardware Capabilities

SCALABLE INSTALLATION OPTIONS
Custom Solutions for Every Building
You don't always need a brand new installation to get modern features. We specialize in modernizing existing hardwired infrastructure to save you money, as well as installing completely new long-range wireless systems for warehouses and difficult-to-wire spaces.

System Retrofit & Takeover: Have a legacy DSC or Honeywell system? We maximize your investment by reusing your existing wired sensors. We simply upgrade the central panel to give you full app control and LTE monitoring without the cost of a full rewire.
Wireless Commercial: Perfect for heritage buildings, glass offices, or finished spaces where wires are impossible. We install award-winning wireless systems (Ajax / DSC Neo) that look sleek and perform flawlessly.
Multi-Site Management: Managing 5 locations? Stop logging in and out of different accounts. Sync employee codes across all your buildings instantly and view arming status on a single dashboard.

BUSINESS INSIGHTS
Run Your Business from Anywhere
You can't be at the shop 24/7 but your security system can. Our mobile app acts as a remote command centre, giving you total visibility into your daily operations and helping you manage staff access across multiple sites instantly.

User Code Control
Instant access management. Create temporary codes for cleaners, revoke access for terminated staff, and manage multiple sites from one screen.
Visual Verification
Stop guessing. If an alarm trips, MotionCam sensors send a photo series to your phone instantly, confirming if it’s a thief or just staff.
Smart Automation
Eliminate human error. Schedule your system to automatically arm itself at closing time, ensuring your facility is never left unprotected—even if staff forget.
Open/Close Reports
Track your hours. Receive a notification the exact moment the shop is opened or closed, so you know when staff arrive and leave.
TRANSPARENT ADVICE
We Match the Technology to Your Workflow
Not every business needs to manage 50 employee codes from a smartphone and not every warehouse needs visual verification sensors. The platforms we use (DSC, Ajax, Alarm.com and Honeywell) each serve a different purpose.
Our Promise: We won't oversell you on features you’ll never use. During your consultation, we ask the right questions to ensure you get the most reliable system for your specific daily operations.
📹 A Note on Video Integration
Unified vs. Separate: We can combine your intrusion and video into a single app (via Ajax or Alarm.com) for convenience, OR keep them separate (using WatchNET) to give you a professional 5-Year Warranty and Zero Monthly Video Fees. The choice is yours.
We Help You Decide:
🛡️ Reliable Retrofit & Takeovers (Budget Friendly)
Best for: Small retail, offices, and businesses with existing panels.
- ✅ Platform: DSC PowerSeries or Honeywell with LTE Communicator.
- ✅ The Benefit: Maximize your investment. If your existing panel works, we keep it. We reuse your wired sensors and upgrade the communicator to give you full app control: Arm/Disarm, User Code Management, and Instant Notifications.
- ⚠️ The Difference: Ideal for single locations. It lacks the multi-site code syncing found in the Enterprise tier.
⚡ Smart Commercial (The Modern Standard)
Best for: New installations, warehouses, and businesses wanting speed.
- ✅ Platform: Ajax Wireless.
- ✅ The Benefit: Our #1 Choice for Modern Business. Experience the fastest app on the market with dual-path reliability (Wi-Fi + LTE). Install upgraded MotionCam sensors to get instant photo verification sent to your phone, confirming if it’s a thief or just staff.
- ⭐ Video Ready: Want continuous eyes on site? You can easily add Integrated Cameras to the system for live HD streaming and recording history directly in your security app.
🏢 Enterprise Management (Multi-Site Control)
Best for: Franchises, multi-location businesses, and high staff turnover.
- ✅ Platform: Alarm.com Commercial.
- ✅ The Benefit: Total Administrative Control. Add or remove employee codes for 5 different locations instantly from a single dashboard. View detailed open/close reports to track staff hours and activity.
- ⭐ Huge Cost Saver: Already have a DSC Neo or PowerSeries (v4.6+)? You might not need a new system. We can often unlock these enterprise features just by installing an LTE communicator—saving you the cost of a full panel replacement.

THE ALLIANCE DIFFERENCE
Reliability Is No Accident.
Commercial environments—from dusty warehouses in Lincoln to high-traffic retail in St. Catharines—demand more than "peel-and-stick" sensors. A generic installation often leads to loose contacts, false alarms, municipal fines and 3:00 AM wake-up calls you don't need.
We build systems to withstand the daily grind of your business. Our in-house technicians don't just hang devices; they engineer stability. We prioritize secure mounting, clean cabling and rigorous zone testing to ensure every sensor is communicating perfectly before we leave. The result is a system that remains stable for years, catching actual intruders rather than just ghosts.
