Why Choose This with Smart Shield Systems

• Pro power/chime setup: we size transformer power, install the power module, and wire for mechanical or digital chimes per the guide.

Frequently Asked Questions

What Wi-Fi does it use?

The VDB770 connects on 2.4 GHz (802.11 b/g/n) and includes a 2×2 antenna to improve range.

What power do I need?

A standard doorbell transformer 16–30 VAC (≥10 VA) works. It can also be powered 15–30 VDC (~8 W) when installed without a chime, per installer documentation. We verify power during install.

Will it work with my digital chime?

Yes—but digital chimes require the internal battery/heater installed. If your doorbell shipped with a battery-less insert, we swap in the ADC-VDBA-770BAT kit.

How well does it see at night?

Built-in IR provides visibility up to ~15 ft (5 m) and the sensor operates at 0-lux with IR.

Does it reduce false alerts?

Yes—on-device Video Analytics prioritize people and reduce nuisance motion. We tune zones and sensitivity for your porch.
