Abstract

A door scope and surveillance camera capable of improving security by making it difficult to identify the capturing direction or the observed position from the front surface direction of the lens are provided. A door scope (10) is provided with a lens mechanism (9) having an objective lens (11) facing the observed position and an eyepiece lens (12) which deflects the light of the observed position having passed through the objective lens (11) to form an image. The image formed by the eyepiece lens (12) is the image of the position inclined to the front surface direction of the objective lens (11).
