Abstract

Apparatus comprising in combination a TV monitor and a closed circuit TV camera including a wide angle lens for receiving and focusing a wide angle image of a first subject matter onto a photosensitive surface of the TV camera and including a telephotolens and a periscopic prism for receiving and focusing an enlarged image of a second subject matter, located substantially the same distance from the TV camera as the first subject matter, onto the photosensitive surface of the TV camera.

Claims

1. An apparatus for providing simultaneous surveillance of an entryway and identification of a person desiring passage through the entryway, said apparatus comprising in combination:

1. a TV camera for providing a TV signal of two simultaneously received separate images, said camera including a vidicon tube having a front face with an inner photosensitive surface;

2. first lens means secured to said TV camera and having a first focal length for imaging a wide field of view of a first subject matter such as an entryway onto a first area of said photosensitive surface;

3. second lens means secured to said TV camera and having a second focal length for imaging an enlarged image of a second subject matter such as an identification card located substantially the same distance from said camera as said first subject matter onto a second area of said photosensitive surface simultaneously with said first subject matter; and

4. viewing means remote from said TV camera and operatively connected to said TV camera for receiving said TV signal to proVide a real-time image of said first subject matter simultaneously with said second subject matter.

2. an exit face located adjacent to said tube face for transmitting said enlarged image to said vidicon tube, and

3. second lens means secured to said TV camera and having a second focal length for imaging an enlarged image of a second subject matter such as an identification card located substantially the same distance from said camera as said first subject matter onto a second area of said photosensitive surface simultaneously with said first subject matter;

and

4. viewing means remote from said TV camera and operatively connected to said TV camera for receiving said TV signal to proVide a real-time image of said first subject matter simultaneously with said second subject matter.
