Abstract

A door mountable security system including a first fiber optic image conduit, a video camera having a lens visually coupled to one end of the fiber optic image conduit and a first video output; a miniature video recorder operable from a battery power source, the miniature video recorder having a video input in connection with the video output of the video camera and an electrically activated record control input; a battery pack in power supply connection with the miniature video recorder and having sufficient power output to power the miniature video recorder; a motion detecting device including a pendulum switch having an electrically conductive plumb-bob pendulum contact and an electrically conductive metal ring contact; and a timer output device having a timed control output in electrical connection with the electrically activated record control input of the miniature video recorder and an electrical control input in electrical connection with the pendulum switch in a manner such that electrical contact between the pendulum contact and the ring contact causes the timed output of the timed output device to generate a signal activating the record control input of the video recorder for a predetermined period of time.

Claims

1. A door mountable security system comprising:

a first fiber optic image conduit;

a video camera having a lens visually coupled to one end of said fiber optic image conduit and a first video output;

a miniature video recorder operable from a battery power source, said miniature video recorder having a video input in connection with said video output of said video camera and an electrically activated record control input;

a battery pack in power supply connection with said miniature video recorder and having sufficient power output to power said miniature video recorder;

a motion detecting device including a pendulum switch having an electrically conductive plumb-bob pendulum contact and an electrically conductive metal ring contact;

a timer output device having a timed control output in electrical connection with said electrically activated record control input of said miniature video recorder and an electrical control input in electrical connection with said pendulum switch in a manner such that electrical contact between said pendulum contact and said ring contact causes said timed output of said timed output device to generate a signal activating said record control input of said video recorder for a predetermined period of time; and

a door having a security device chamber formed therein and sized to receive said video camera, said miniature video recorder, said battery pack, said motion detecting device, and said timer output device; and

wherein;

one end of said first fiber optic image conduit is positioned within a hole formed through an external surface of said door.

2. The door mountable security system of claim 1, further including:

a second fiber optic image conduit, and

a prism image splitter; and

wherein;

said first and second fiber optic image conduits are visually coupled to said video camera through said prism image splitter.

3. The door mountable security system of claim 1 wherein:

a free end of said second fiber optic image conduit is provided with a fish-eye lens.

4. The door mountable security system of claim 1, wherein:

said first fiber optic image conduit is installed through a door knob of said door.

5. The door mountable security system of claim 1 wherein:

said video recorder is a high-8 format video recorder.

6. The door mountable security system of claim 1 wherein:

a free end of said first fiber optic image conduit is provided with a fish-eye lens.

7. The door mountable security system of claim 2 wherein:

said video recorder is a high-8 format video recorder.

8. The door mountable security system of claim 2 wherein:

a free end of said first fiber optic image conduit is provided with a fish-eye lens.

9. The door mountable security system of claim 3 wherein:

said video recorder is a high-8 format video recorder.

10. The door mountable security system of claim 3 wherein:

a free end of said first fiber optic image conduit is provided with a fish-eye lens.
