<p>If quality of video is not so important to you, then you can use effect, which is used on public transport windows:
<a href="https://i.sstatic.net/iknr9.jpg" rel="nofollow noreferrer"><img src="https://i.sstatic.net/iknr9.jpg" alt="enter image description here"></a></p>

<p>It is when you use lot of dots on the glass. From the outside it looks like semitransparent image. But from inside it will look like that:
<a href="https://i.sstatic.net/9CEzx.jpg" rel="nofollow noreferrer"><img src="https://i.sstatic.net/9CEzx.jpg" alt="enter image description here"></a></p>

<p>With correct focus dots will be less visible on video.</p>

<p>And second option is to use half-silvered mirror.</p>

<p>I am building an Arduino (<a href="https://www.arduino.cc/en/Main/ArduinoBoardUno" rel="nofollow">https://www.arduino.cc/en/Main/ArduinoBoardUno</a>) device that will record video based on a motion sensors, as well as other data in the environment. The thing is, I need to record from within a box to the outside, but the camera should not be visible. Any ideas or advice on how and what to use?</p>

If the camera can see you, you can see the camera (except possibly through a half-silvered mirror). All you can do is disguise it, for example "teddy-bear cams". How big is the lens opening? What are the surroundings? How is the scene lit? More details will help.
