No, a video smart lock cannot be added to the HomeBase included with this eufyCam S4 system. eufy video smart locks (such as the FamiLock S3 Max) are designed to work standalone via the eufy Security app and connect to your Wi‑Fi directly. They do not pair with the HomeBase or the Smart Display E10.

No, you do not have to pay a monthly subscription. The eufyCam S4 system is designed for local storage (using the HomeBase 3). All core features—live viewing, recording, AI detection, and alerts—work for free, with no monthly fees. This is why the product name highlights "0 Monthly Fee".

Yes, the eufyCam S4 system works with Google Home. You can link your eufy Security account in the Google Home app to view live camera feeds on Google Nest Hub and Chromecast devices, and use voice commands to control them. The Smart Display E10 is a separate eufy device, but the cameras themselves fully integrate with Google Home.

Professional installation is not required for this system. The cameras are solar-powered and wireless, so they can be easily mounted with the included hardware. The Smart Display E10 is plug-and-play and can be set up on a table or wall-mounted. However, if you prefer a cleaner look or need help with optimal placement, you can hire a professional. The eufyCam S4 cameras operate on 2.4 GHz Wi-Fi only. The Smart Display E10 connects via Wi-Fi (likely the same network) for video streaming and control. 5 GHz is not supported for the cameras.

Unfortunately, it’s not supported.
