Smart Wi-Fi Window Security Camera SONOFF CAM-S3W

Smart Wi-Fi Window Security Camera SONOFF CAM-S3W

SONOFF CAM-S3W GlassView is a smart security camera designed specifically for window mounting, allowing you to monitor your outdoor environment without leaving your home. The camera is mounted on the inside of the window , so it is protected from rain, snow and other weather conditions. There is no need to drill into the window or wall for installation - the camera is attached using a 3M adhesive mounting system.

The camera has a 3 MP sensor and provides 2K color images day and night. A special anti-reflection algorithm helps reduce reflections from glass, making the image clearer. Since the camera is designed to be mounted behind glass, it does not have additional infrared or white light illumination, which can cause strong reflections. Color night vision is best seen in ambient light.

CAM-S3W supports 2.4GHz and 5GHz Wi-Fi , providing more flexible wireless connectivity. The built-in AI human detection function helps to more accurately recognize human movements and send real-time notifications. It also supports two-way audio , allowing you to not only hear what is happening, but also talk through the camera.

One of the main advantages of this camera is local control without a cloud subscription . Using SONOFF's OpenEdge native web interface, you can view live images, change settings, and update firmware directly through a browser. The camera also supports RTSP and ONVIF , allowing it to be integrated with systems such as Home Assistant .

Videos can be stored locally on a TF/microSD card with a capacity of up to 128 GB . No cloud service subscription is required for video recording. Card is not included.

The camera can be mounted on single or double glass, and the included mounting brackets allow you to adjust the camera's angle. The adjustable bracket allows you to adjust the view in four directions, so the camera can be used at both lower and higher heights.

Your first fully local window camera

SONOFF CAM GlassView — smart window camera

Traditional cameras aren’t always the ideal solution for window surveillance. Outdoor cameras can be difficult to install and maintain, and traditional indoor cameras can suffer from glare and difficulty viewing through glass at night. A window camera offers a simpler alternative.

1. Note: To prevent glass reflections from interfering with image capture, this window camera does not have infrared or white light illumination. Full-color night vision works best in ambient lighting (e.g. moonlight or low-light living spaces).

The magnetic design makes it easy to attach and remove the camera, and the adjustable angle bracket allows for precise adjustments
view in four directions. Choose the angle you need — even if the camera is installed on a higher floor.

Higher floors or slanted view

Regular use for better glare protection

Campers with limited space, etc.

Access and manage CAM GlassView directly through the OpenEdge native web console — no cloud connection required.
View live video, set camera functions, and enable RTSP/ONVIF locally from your browser, so you don't have to worry about privacy.
