Claim:
A surveillance system for observing a scene without the knowledge of those who are present at the scene, comprising: a nonplanar enclosable concealment container substantially formed from a glass having (1) a deep red color that reflects visible light and is permeable to the passage of a substantial segment of rays of light in the infrared region impinging thereon, and (2) a thickness such that said nonplanar enclosable concealment container is substantially black to a human eye and any object placed within said nonplanar enclosable concealment container is not visible to said human eye through said glass; and an infrared camera having a receptor, said infrared camera being positioned within said nonplanar enclosable concealment container at a location such that said infrared rays pass through glass and into said receptor of said infrared camera, said infrared camera enabling a viewer to observe said scene without the cognition of those participating therein without having to add a light source.
