# SONOFF CAM-S3W

*SONOFF / CAM-S3W*

> The CAM GlassView (CAM-S3W) is a 2K window camera that sticks to glass with an adhesive bracket. A browser-based local web console turns on RTSP and ONVIF, and the camera records to a microSD card up to 128 GB with no cloud storage. It suits Google Home and Alexa users through an integration (the maker's cloud). Home Assistant users reach it through an integration (local Wi-Fi control).
