    Qolsys IQ · Security-grade panel

    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.
