Sonoff CAM GlassView (CAM-S3W) smart window camera, 2K, Wi-Fi 2.4/5 GHz
Description
Sonoff CAM GlassView (CAM-S3W) – 2K Wi-Fi camera that mounts on the inside of a window
The Sonoff CAM GlassView is a smart camera that attaches to the inside of a window and films outside, with no drilling. The 3MP sensor, F1.0 aperture and the anti-glare and anti-reflection algorithm for glass deliver 2K colour video with a 100° field of view. It detects people with AI, sends real-time alerts and offers two-way audio and an audio alarm, with all features available without a subscription.
Note: the camera has no IR illumination and no white fill light, to avoid reflections in the glass; colour night vision depends on the ambient light. There is no cloud storage: recordings are saved to a TF/microSD card of up to 128GB, sold separately. It is intended for indoor use only, mounted on the inside of the window. It is powered at 5V ⎓ 1A via USB-C and connects to 2.4 GHz or 5 GHz Wi-Fi.

- 2K colour video, 3MP sensor, F1.0 aperture, 100° field of view

Practical use cases:
- Upper-floor apartment: keep an eye on the car park or the building entrance right from the window, without mounting anything on the facade.
- Rented home: adhesive and magnetic mounting leaves no holes in the walls or window frames.
- House with a yard: the camera films the driveway through the glass, and AI person detection sends an alert when someone approaches.
- Local setup: the RTSP/ONVIF stream goes into Home Assistant, with no cloud account and no subscription.
