Abstract

Antitheft surveillance camera arrangement for reciprocatingly scanning a given area. The camera is able to automatically expose film therein. The antitheft surveillance camera arrangement includes a motorized scanning mechanism mounted on the outside of the camera case. The motor continuously operates in one direction. The outside mounting enables the motor mechanism to be more readily accessible for servicing and reduces the inertia of the reciprocating camera case.

Claims

1. A surveillance camera device which reciprocatingly scans and enables the automatic exposure of film or other type of surveillance, said reciprocatingly scanning device comprising:

camera case means for mounting cameras therein to selectively take photographs during said scanning;

a scanning mechanism located outside of said case for reciprocatingly moving said camera case through an adjustable arc;

said mechanism including;

means for adjusting said arc;

output shaft means for mounting said case to said mechanism;

lever arm means affixed to said output shaft means for causing said shaft to oscillate through the arc;

linear reciprocating means for actuating said lever to move said shaft;

motor means mounted on said mechanism;

drive shaft means operated by said motor means to rotate in only one direction;

cam means rotated by said drive shaft; and

cam bearing means actuated by said cam means and coupled to said linear reciprocating means to translate said rotating motion to linear reciprocating motion whereby said case is caused to reciprocate through said arc.

2. The surveillance device of claim 1 wherein said cam means comprises a heart-shaped cam;

and wherein said cam bearing means are located at opposite sides of said heart-shaped cam.

3. The surveillance device of claim 2 wherein said means for adjusting said arc comprises a series of apertures along the length of said lever arm means;

5. A surveillance camera device which reciprocatingly scans and enables the automatic exposure of film or other type of surveillance, said reciprocatingly scanning device comprising:

camera case means for mounting cameras therein to selectively take photographs during said scanning;

a scanning mechanism for reciprocatingly moving the camera case through an adjustable arc;

means for adjusting said arc, output shaft means for mounting the case to said mechanism;

lever arm means affixed to said output shaft means for causing said shaft to oscillate through the arc;

linear reciprocating means for actUating said lever to move said shaft;

said means for adjusting said arc comprising a series of apertures along the length of said lever means;

pin means for selectively attaching said linear reciprocating means to said lever arm means at a desired one of said apertures;

motor means mounted on said mechanism, drive shaft means operated by said motor means to rotate;

cam means rotated by shaft;

cam bearing means actuated by said cam means and coupled to said linear reciprocating means to translate said rotating motion to linear reciprocating motion whereby said case is caused to reciprocate through said arc;

axis member means for insertion through said axis member hole means and said central hole; and

pin means for insertion in said coaxially aligned set of holes to select the desired angle of inclination.

6. The surveillance device of claim 5, wherein control means are provided for automatically controlling the exposure of film in the camera case whereby the shutter is operated for a first period and remains inoperative for a second period of time during the reciprocating scanning cycle.

7. The surveillance camera means of claim 5 wherein said cam means comprises a heart-shaped cam, and wherein said cam bearing means are located on opposite sides of said heart-shaped cam.

8. A surveillance camera device which reciprocatingly scans and enables the automatic exposure of film or other type of surveillance, said reciprocatingly scanning device comprising:
