The patented entrance door Pirnar Theatrica opens automatically without needing to be touched. It is sufficient just to look at it. A built-in facial recognition system will identify the owner and then gently open the massive door which subsequently closes of its own accord. In addition to the single-door, there is also a double-door version, which creates the impression of a wall that is opening. The door, which does not require a handle, can be produced in wood, stone, glass or aluminium. Installation is straightforward and easy.
