Google devices can be managed through a shared home app, where users can view camera feeds, review video history, adjust thermostat settings, and connect compatible temperature sensors. Compatible smart-home displays can show live camera or doorbell video, while the app helps users monitor and control devices from one place.

Choose wired Google devices when a fixed location, continuous power, and features such as longer clips or continuous recording with a compatible subscription fit the installation. Choose battery-powered devices when flexible placement and fewer wiring requirements matter, while planning for periodic recharging and considering access to the device, coverage area, and indoor or outdoor conditions.

Plan Google device placement by using indoor cameras for rooms you want to monitor, outdoor cameras for exterior views, and a video doorbell at the main entry point, with access to power where required. Place the thermostat in a representative central area, then add remote temperature sensors in rooms that run warmer or cooler so the system can use those readings for comfort control.

Before adding Google devices, confirm that the system works with the Google Home app and compatible Google displays, and check whether each device needs wired power, a rechargeable battery, or a separate power cable. For a wired doorbell, verify a 16/24VAC, 10–40VA transformer and chime, while the thermostat supports compatible HVAC systems up to 4H 2C and may require checking the existing wiring.
