Smart Shield Systems
IQ Doorbell
Turn your existing wired doorbell into a smart, automated sensor—without changing the outdoor button. The IQ Doorbell connects at the indoor chime and enrolls to your IQ Panel as zones you can use for alerts, chimes, and automations (e.g., turn on the porch light or trigger recording).

Why Choose the IQ Doorbell with Smart Shield Systems
No exterior retrofit: Keep your current doorbell button and chime wiring
Smart automations: Create rules like “when the doorbell rings, turn on lights or record video”
Pro install & setup: Clean wiring at the chime, zone naming, and app training
Local experts: Smart Shield Systems supports you long after installation
Key Features
Wires to the indoor chime (TRANS/FRONT/REAR terminals); mounts on or inside the chime cover.
Front & rear support: Learns in as two zones so you can name and automate each separately.
Use with scenes & rules: Turn on porch lights or trigger cameras when pressed; customize chimes.
Indoor, low-profile install using included adhesive (no new holes at the doorway).

Frequently Asked Questions
Do I have to replace my current doorbell button?
No. The IQ Doorbell wires to the indoor chime, so you keep your existing exterior button and chime.
Can I automate lights or cameras when the doorbell rings?
Yes. You can create rules like “when doorbell rings, turn on porch light” or start camera recording. We’ll set this up during installation.
Will it handle both my front and back door?
Yes. It supports two doorbells and learns in as two separate zones so you can name each one and choose different chimes/actions.
Where does the device get installed?
Inside, at the doorbell chime. We wire to the TRANS, FRONT, and (optional) REAR terminals and mount the sensor on/inside the chime housing.
What maintenance is required?
Replace the two CR2032 batteries with the exact type when due; your panel will supervise and alert for low battery.
