Philosopy & Why We Use DCS + Alarm.com

We build for reliability, not gimmicks

We choose DSC because their control panels and ecosystems are proven, robust, and widely supported.

Integrated, not patched

Our Alarm.com integration isn’t an add-on — it’s built into the design. You get remote arm/disarm, alerts, automations, and live status, all in one system.

Scalable & Future-proof

Whether you're starting with a few zones or planning expansion to 50+, DSC + Alarm.com lets you grow without a full rip-and-replace.

Transparent, flexible, and local.

We don’t obscure costs or lock you into perpetual contracts. Your system is ours to build, support, and evolve — your choice to continue or upgrade.

What Really Makes a Good Alarm System

Control & Intelligence

The heart of every system is the control panel. A good panel should manage zones reliably, allow expansion, integrate with smart devices, and use encrypted communication.

DSC’s PowerSeries / NEO line gives us this foundation.

Connectivity & Monitoring

With Alarm.com, your system isn’t just local — it’s smart, remote, and interactive. You’ll get instant alerts, remote arm/disarm, and integration with cameras, locks, and automation.

Redundancy & Reliability

We design for backup paths — cellular + Ethernet, battery backups, supervision — so your alarm works even when power or Internet fails

Sensing & Coverage

Motion sensors, door/window contacts, glass break, shock, and environmental sensors (smoke, flood) — we choose the right mix so you’re covered without overkill

Alerts & Intelligence

Your system can tell you which door was triggered, if a zone is low battery, or if communication fails. That’s actionable security, not noise.

3-Year Warranty, Total Peace of Mind

Your system is covered—cameras, recorder, and installation—for a full 3 years. No surprises. Just protection you can count on.

At Onyx Smart Security, our priority is your peace of mind. Here’s what our satisfied clients have to say about their experience with us:

Excellent and Professional Service! They came in the morning as scheduled and gave us a full quote to update our original system then they managed to fit us in the same day for our convenience. All set up in a couple hours, works beautiful and the complete install looks seamless.The guys explained ever detail and we know they will be there if we need further clarification. Upcoming UTube channels we are told. We highly recommend this company!

Simone

We recently had Onyx install our security system in Meaford. They were very professional and gave great advice. The team was extremely responsive before, during and after installation. Mike was outstanding. Did a great job walking us through the set up and was quick to respond when we had questions later on. Highly recommend.

Cheryl Cardon

We had cameras and alarms installed on our shop. Very happy with the service and products, as well as ongoing monitoring!

Great peace of mind and added security.
