Built on Alarm.com — the platform behind millions of professionally monitored homes.
This device is part of the same ecosystem trusted by leading security dealers across North America. It's designed to be reliable when it matters — and to keep working when consumer-grade smart home gear gives up.
- Engineered for professional monitoring — not a hobbyist cloud you'll outgrow.
- 99.9% platform uptime with dual-path cellular + Wi-Fi failover, so signals get through even if the internet is cut.
- Encrypted video with on-device edge AI — people, vehicles, and animals are recognized locally before anything is uploaded.
- Dealer-only hardware tier — not sold on Amazon, not repackaged from consumer parts.
- Crash & Smash protection: the panel signals monitoring the moment it's tampered with, not after the countdown.
- Geofencing, smart schedules, and one-tap arming built in — no third-party subscriptions.
A true security panel — not a smart-home hub with a keypad glued on.
The Qolsys IQ platform is built for professional installation from the ground up. Every component — the radio, the tamper detection, the encryption, the cellular backup — is engineered to keep working when consumer gear fails.
- Dual-path LTE + Wi-Fi — signals get to monitoring even if the internet is cut.
- Glass-break detection built into the panel itself — no extra sensor to buy.
- Built-in HD panel camera captures a photo of anyone who disarms — including intruders.
- PowerG native — pair sensors up to 2 km away with encrypted, two-way wireless.
- UL-listed and pro-monitoring grade — the same panel used in commercial installations.
- 7" HD touchscreen with an on-board Alarm.com app, weather, and smart-home control.
