Smart Shield Systems
IQ Glass-S
Protect rooms with windows, sliders, or glass doors using an acoustic glass-break sensor that listens for the specific frequency pattern of breaking glass. The IQ Glass-S uses S-Line encrypted 319.5 MHz signaling to your IQ Panel and is designed to be effective within typical living spaces—clean install, battery powered, and professionally tuned by Smart Shield Systems.

Frequently Asked Questions
Install on a wall opposite the windows being protected or on the ceiling (in rooms with windows on multiple sides). Keep it at least 3.3 ft from the glass and 4 ft from noise sources (speakers, TVs, HVAC). We’ll verify coverage during testing.
When set to MAX, the sensor is rated for up to 20 ft line-of-sight to the glass; lower ranges (13 ft, 8 ft, 5 ft) are selectable to match the room.
Yes. The IQ Glass-S listens whenever the system is armed—including Stay—so perimeter windows can be protected while you’re home.
Open-air radio range to the panel is listed up to ~600 ft; actual range depends on construction and placement. We confirm signal strength during installation.
We tune sensitivity using the built-in DIP switches, mount at recommended distances, and avoid noisy sources in the immediate vicinity—best practices that keep protection high and nuisance trips low.
