Frequently Asked Questions

How does it connect to Wi-Fi and my account?

Use AP mode at vdb750install.com (or 192.168.1.1) or WPS; once online, we add it to your Alarm.com account and verify live view and alerts.

What power does it need?

Either 16–24 VAC (10–40 VA) doorbell transformer (16VAC/10VA recommended) or 15–24 VDC (6–20 W). We confirm your wiring and chime type during install.

Is it weather-resistant?

Yes—IP65 and rated for real-world temperatures noted above. We still prefer a shaded, vertical mount for longevity and image quality.

Does it only alert on people?

By default we enable People Detection so you get fewer false alerts from cars, shadows, or trees.
