Sonoff CAM-S3W GlassView: 2K window camera that captures outside without reflections or holes
The Sonoff CAM-S3W GlassView is a Wi-Fi camera designed to be placed indoors, attached to a window pane, and capture what's happening outside. This protects it from rain and tampering, requires no drilling in the wall, and has your home Wi-Fi just a few meters away. It records in 2K with a 3 MP sensor, F1.0 lens, and 100° field of view, and has no infrared LEDs: at night, the image remains in color with the light of streetlights and lanterns, without reflections on the glass. It detects people with AI, records to a microSD card up to 128 GB without a subscription, can be configured via the eWeLink app or local web console , and integrates with Home Assistant via RTSP and ONVIF .
Why a window camera: the limitations of outdoor and indoor cameras
An outdoor camera must be mounted on the wall, running power to the mounting point. It remains exposed to rain and sun, and anyone can reach it and remove it. An indoor camera placed behind a window has the opposite problem: the glass reflects the sun during the day and, at night, the light from its infrared LEDs , which bounces off the glass and covers the scene. The CAM-S3W was created for this situation: it attaches directly to the glass, from the inside, with an adhesive bracket, and its lens is designed to shoot through the window. If you need a camera to mount outside, you can find the Sonoff CAM-B1P outdoor camera and other Wi-Fi cameras in the catalog.
Clear image through glass: no infrared and anti-reflection algorithm
The comparison shows the same scene captured by the CAM-S3W and a standard camera behind glass. During the day, the anti-glare algorithm reduces glare and reflections, so the garden and pool remain visible. At night, the difference is more marked: the CAM-S3W has no infrared illuminators or white lights and uses the available light, such as street lamps, garden lights, or the moon, maintaining the color image, while the standard camera switches to black and white with the infrared reflecting off the glass. The downside is important to note: in a completely dark area, with no external light, the CAM-S3W's image deteriorates.
Magnetic bracket tilts 18° in four directions
The camera isn't glued to the glass; the bracket is. A magnet in the camera body attaches to the metal part of the bracket, so you can detach it to move it, insert a microSD card, or clean the glass, and then put it back in place without removing the adhesive. With the bracket tilted , the camera can look up, down, or sideways at an 18° angle, useful on higher floors for viewing the driveway or a side door. The hook-and-loop mounts used by other window cameras, however, provide a narrower view, less precise alignment, and a fixed orientation.
Three 3M adhesive brackets: small, large and angled
The package includes three brackets , all with 3M adhesive. The small bracket is used where space is limited, such as on the narrow glass of a French window or next to the frame. The large bracket is the standard one, and Sonoff recommends it especially on double-glazed or thicker glass, where it holds the camera more firmly. The angled bracket is used when the window doesn't face directly toward the monitored area: from the first floor toward the gate, or sideways toward the parking space. Sonoff recommends installation at a maximum height of 2 meters .
Installation without drilling in four steps
Installation takes just a few minutes and requires no tools. First, thoroughly clean the glass on both sides in the chosen area. Then, attach the camera to the bracket and check the live view in the eWeLink app or web console. Once the position is correct, remove the camera, peel off the protective film from the adhesive, and press the bracket onto the glass. Finally, reattach the camera with the magnet and secure the 3m USB-C cable with the four included cable clips. A shaded window is best: prolonged direct sunlight can weaken the adhesive over time. The 5V 1A USB power adapter is not included.
Local network only: Web console, RTSP and ONVIF without apps and without cloud
The CAM-S3W can work entirely on a local network . You can configure it from a browser on a computer connected to the same network, integrate it with Home Assistant or a NAS via RTSP and ONVIF , and save recordings to a microSD card: in this configuration, neither the app nor a cloud account is required, and the images stay at home. The eWeLink app is used for initial pairing and to receive notifications on your phone, if you want them. Cloud storage for recordings is not supported: there is no subscription to pay, and likewise, there is no online archive of clips.
OpenEdge Web Console: Live 2K, Networking, AI Detection, and Updates
The OpenEdge web console opens from a browser with the camera's IP address and the password you set. From here, you can watch live video in 2K , configure or change your Wi-Fi network, and adjust the camera's features: AI detection , image, and audio. In the system section, you can set the time zone and update the firmware over- the-air , while the RTSP/ONVIF section enables video streaming and displays the login information for external platforms. Please note: the web console currently does not play microSD recordings ; these can be viewed using the app or connected software via RTSP.
Open API JSON-RPC 2.0 over HTTP and WebSocket for video surveillance software
Those integrating video surveillance systems also have an open API : the camera accepts JSON-RPC 2.0 commands via HTTP and real-time communication via WebSocket . This allows it to integrate with video management software (VMS) or a custom-developed platform, not just home apps. Sonoff publishes the API documentation in its support center. For home use, it's not necessary: to view and record in Home Assistant, a NAS, or software such as video surveillance, simply enable RTSP or ONVIF from the web console.
Home Assistant via ONVIF: Camera movement triggers automations
The CAM-S3W connects to Home Assistant via ONVIF or RTSP, without going through the cloud. With ONVIF, Home Assistant also receives the camera's motion sensor, which you can use as a trigger in automations: for example, when the camera detects motion, it starts recording or turns on the garden lights. The same RTSP stream can be sent to a NAS or a software video recorder that supports RTSP cameras. Sonoff publishes the guide to integrating with Home Assistant in its help center. If you also want to control doors and passages, add Sonoff Zigbee sensors with a hub like the ZBBridge Ultra or Bridge Max .
Where to install it: offices, villas, campers, condominiums and shop windows
All it takes is a window or glass door facing the area to be monitored. In an office, it records the entrance through the glass door; in a house , the front or back garden; in a camper , the area around the vehicle while parked. In an apartment, it monitors the courtyard or entrance to the building from the window; in a shop , the window and entrance; and in a townhouse, the driveway and parking space. It works best on single-glazed windows; slight reflections may appear on double-glazed windows; however, tinted, low-emissivity, or patterned glass are not recommended.
Local recording on microSD up to 128 GB, without subscription
All recordings remain locally, on the microSD card up to 128 GB inserted in the camera and sold separately, such as the BanQ High Endurance 128 GB card . You can record continuously 24/7 or only when events occur, and there's no subscription fee. Supported features include event recording, AI person detection , smart scenes, and the ability to use a sensor's status as an event: a Sonoff sensor triggering, such as an open door, becomes an event for the camera. Without the card, events still appear in the app list, but without images or clips to review.
AI-powered people detection and real-time alerts
AI person detection distinguishes between people and unimportant movement and sends a real-time alert to your phone. In the Sonoff example, someone approaches the car in the driveway at night: the camera detects it, a notification arrives, and the camera emits an audible alarm, while in the bedroom the smart display shows the scene. The CAM-S3W also supports two-way audio . To also control doors and windows, you can add Sonoff Zigbee sensors, such as the SNZB-04PR2 door and window sensor , which requires a Sonoff Zigbee hub.
Sonoff Sensors and Camera: Sensor Status Becomes an Event
Live on Echo Show and Nest Hub with Alexa and Google Home
With Alexa and Google Home, the camera can be viewed on smart displays with a screen. Live video and two-way audio work on Amazon Echo Show 5, 8, 10, 11, and 15 , as well as on Google Nest Hub , second-generation Nest Hub, and Nest Hub Max: just say, for example, "Alexa, show me the backyard." There's no video on speakers without a screen. Sonoff doesn't support Apple Home and Matter for this camera.

Frequently Asked Questions
Does it work through any glass?
It performs best on single-glazed glass. Slight reflections may appear on double-glazed glass; tinted or low-emissivity (Low-E) glass degrades the image, especially at night. Decorated or frosted glass and mosquito netting in front of the lens are not recommended.
Can you see at night?
Yes, in color, but with the available light: streetlights, spotlights, or the moon. It has no infrared or its own light, so as not to reflect on the glass. In a completely dark area, the image deteriorates.
Do you need the app to use it?
For initial pairing, use the eWeLink app. Afterward, you can view live video, change settings, and update firmware from the local web console without an app or account. The web console does not play recordings.
Do you need a subscription?
No. It records continuously or on events to a microSD card up to 128 GB (not included). Cloud storage is not supported. Without a card, events appear in the app, but without images or clips.
Does it work with Home Assistant?
Yes, via RTSP or ONVIF, which you enable locally from the web console. With ONVIF, Home Assistant also receives motion detection for use in automations.
Does it work with Alexa and Google Home?
Yes, for live viewing and two-way audio on smart displays: Echo Show 5, 8, 10, 11, and 15, Google Nest Hub, 2nd gen Nest Hub, and Nest Hub Max.
Does it work with Apple Home?
Sonoff does not claim Apple Home or Matter compatibility for this camera.
Can I mount it outside?
