It would be possible to create a screen based on two way mirror to be able to put camera under the screen.

Yes, it is possible to create a screen based on a two-way mirror to place a camera underneath or behind it. Search result [4] explicitly confirms this application: 'Security cameras can be hidden behind a two-way acrylic sheet, disguising itself as a regular mirror.' The source describes how two-way mirrored acrylic sheeting allows cameras to be installed behind the mirror while maintaining a normal mirror appearance from the front. This demonstrates the feasibility of the concept for both home security and other applications. Additionally, search results [1], [2], and [3] show existing rear-view mirror screen systems with integrated cameras, proving that mirror-based screens with embedded cameras are already commercially viable technology.

A two-way mirror concept can work in principle because the key requirement is directional light management: the display must emit enough light toward the viewer while still allowing some external light to pass down to the camera. That is physically possible with partially transmissive layers, and under-display cameras already demonstrate the broader idea. A classic two-way mirror alone is not sufficient as a modern display, but a screen can be engineered with regions or materials that are both emissive/display-capable and partially transparent. When the pixels above the camera are controlled appropriately, the camera can capture through them. The real issue is quality, not possibility. Such a design reduces light reaching the camera and can introduce haze, diffraction, and color artifacts, but those are engineering tradeoffs rather than proof of impossibility. So if the claim is "would it be possible," the correct answer is yes.

A two-way mirror (also known as a one-way mirror) is partially reflective and partially transparent, which allows light to pass through one side while reflecting light on the other. This optical property makes it entirely possible to place a camera behind the screen. In fact, this exact principle has been used for decades in teleprompters, where a camera records through angled glass while the speaker reads text reflected from a screen. Furthermore, modern 'smart mirrors' and hidden camera setups utilize this technology to display a digital interface on the surface while simultaneously allowing a concealed camera to capture video through the glass.

A two-way mirror (or beam splitter) partially reflects and transmits light, allowing ~10-50% transmission depending on the coating. This enables light from the front to reach a camera positioned behind the mirror while the front surface can serve as a display substrate. Display technologies like OLED or LCD can be layered or projected such that emitted light is visible from the front through partial reflection, with minimal interference to the camera path when the rear is kept dark. Prototypes and patents exist for under-display cameras using semi-transparent mirrors or similar optics (e.g., in smartphones), confirming feasibility. While image quality may degrade, the question asks if it 'would be possible,' not optimal.

Yes, this is not only theoretically possible but has already been implemented in real products. A two-way mirror (also called a half-silvered mirror or beam splitter) allows light to pass through from one side while reflecting light on the other side. By placing a display behind the mirror and a camera behind a transparent section, you can capture images through the screen. Several smartphone manufacturers have explored or released under-display camera technology using similar principles. For example, ZTE released the Axon 20 5G with an under-display camera, and Samsung has implemented this in their Galaxy Z Fold series. While these specific implementations use OLED transparency rather than a literal two-way mirror, the concept of using a semi-transparent reflective surface (like a two-way mirror) as a display surface with a camera behind it is entirely feasible. In fact, teleprompters already work on exactly this principle — a two-way mirror reflects text for the speaker while the camera shoots through it from behind. This same concept can be adapted into a screen-camera combination. The physics is straightforward: the two-way mirror reflects enough light to display an image to the viewer while transmitting enough light to the camera sensor behind it. There may be trade-offs in image quality for both the display and the camera, but the fundamental concept is sound and proven.

Two-way mirrors (half-silvered mirrors) are partially reflective and partially transmissive, making this setup physically feasible. A display placed behind the mirror can emit light that passes through to the viewer, while ambient light from the viewer's side simultaneously passes through the mirror to reach a camera positioned behind it. This principle is already used in various applications. Smart mirrors use similar technology where LCD or LED displays sit behind two-way glass, and cameras can be integrated behind the reflective surface. Modern under-display camera technology in smartphones uses transparent OLEDs or precisely engineered pixel gaps that function similarly, allowing the camera to capture images through the display layer while the screen remains active. The key requirement is managing light intensity: the camera side must remain relatively dark to capture a clear image, while the display must be bright enough to punch through the mirror's reflectivity. While image quality trade-offs exist (reduced brightness for the viewer, reduced light for the camera), the configuration is demonstrably possible and has been commercially implemented.

Final Summary

The AI Roundtable reached a swift and unanimous verdict: placing a camera behind a two-way mirror screen is not only possible but is a technology already hiding in plain sight. Claude Opus 4.6 and Gemini 3.1 Pro both pointed to the teleprompter—a decades-old device—as the definitive proof of concept, while GPT-5.4 noted that the real challenge lies in engineering around diffraction and haze rather than any fundamental laws of physics. Sonar Pro and Kimi K2.5 grounded the discussion in modern reality, citing existing smart mirrors and smartphone under-display cameras as evidence that the 'future' is already here.
