eufy Security eufyCam S3 Pro Add-on Cam — 4K Solar Wireless Outdoor Camera with MaxColor Night Vision, SolarPlus 2.0, Radar+PIR Detection, Face Recognition AI, Expandable Local Storage, No Monthly Fee

Bring daylight clarity to night recordings with the eufy Security eufyCam S3 Pro Add-on Cam. Its 4K sensor combined with MaxColor Vision technology delivers highly detailed, color-rich footage in ultra-low light without requiring a spotlight. SolarPlus 2.0 provides dependable, year-round power: use the integrated solar panel for a compact setup or attach an external panel to extend energy coverage. The system supports multiple mounting options and includes backup power for continuous operation. Detection is precise thanks to a dual radar and PIR motion system that identifies human movement and reduces false alerts by 99%, so you receive notifications only for significant events in the areas you define. Smart features include Face Recognition AI, expandable local storage, and no monthly fee for video access. The add-on cam requires HomeBase 3 to operate and works with HomeKit, Alexa, and other voice assistants. Note: video will be 1080P when viewed through HomeKit — update HomeBase 3 to version 3.5.8 or higher and ensure the latest eufy app is installed.
