Dynamic masking mechanism for ceiling-mounted surveillance cameras

Abstract

This invention includes a fixed base and a first shielding part. The fixed base has a fixing part and a sliding groove part, the fixing part for fixing the fixed base to an object; and the fixed base is used to mount a surveillance camera lens; the surveillance camera lens has a field of view. The first shielding part has a first sliding groove mating part and a first shielding plate, the first sliding groove mating part being movable relative to the sliding groove part of the base; the first shielding plate extending from the first sliding groove mating part. The first shielding part can be moved to different positions, forming different shielding ranges for the lens's field of view. This invention achieves the advantages of simultaneously meeting privacy protection and monitoring needs, and the shielding range can be flexibly adjusted.

Claims

1. A dynamic masking mechanism for a ceiling-mounted surveillance camera lens, comprising: A fixed base has at least one fixing part, a sliding groove part, and a receiving space; the at least one fixing part is used to fix the fixed base to an object; the receiving space is used to install a surveillance camera lens, the surveillance camera lens having a field of view; and a first shielding part is disposed on the fixed base and has a first sliding groove mating part and a first shielding plate; the first sliding groove mating part is movable relative to the sliding groove part of the base and extends inward from the first shielding plate; wherein the first shielding part is movable to at least a first position, a second position, and a third position; when in the first position, the field of view is defined as a first field of view range, the first field of view range being greater than or equal to the field of view; when in the second position, the field of view is defined as a second field of view range, the second field of view range being smaller than the first field of view range; when in the third position, the field of view is defined as a third field of view range, the third field of view range being smaller than the first field of view range and larger than the second field of view range.

2. The dynamic masking mechanism for the ceiling-mounted surveillance camera lens as described in claim 1, wherein: The fixing system has an upper arc-shaped body, a lower arc-shaped body and a connecting section connected as one unit; and the fixing part is disposed on at least one of the upper arc-shaped body, the lower arc-shaped body and the connecting section.

3. The dynamic shielding mechanism for the ceiling-mounted surveillance camera lens as described in claim 2, wherein, The fixing part is selected from one or a combination of a steel nail fixing element, a screw fixing element, an adhesive fixing element and a magnetic fixing element.

4. The dynamic shielding mechanism for the ceiling-mounted surveillance camera lens as described in claim 2, wherein, The seat groove is located between the upper arc-shaped body, the lower arc-shaped body, and the connecting section.

5. The dynamic masking mechanism for the ceiling-mounted surveillance camera lens as described in claim 2, wherein: The first sliding groove mating part has an inner vertical abutment part, a horizontal connecting part and an outer vertical abutment part; the horizontal connecting part connects the inner vertical abutment part and the outer vertical abutment part, so that the first sliding groove mating part has a U-shaped structure; and the inner vertical abutment part and the outer vertical abutment part are respectively opposite to the inner side and the outer side of the lower arc-shaped body, and the horizontal connecting part spans across the lower arc-shaped body.

6. The dynamic shielding mechanism for the ceiling-mounted surveillance camera lens as described in claim 1, wherein, The first shielding part further includes a horizontal baffle that extends horizontally from below the first shielding part toward the surveillance camera lens.

7. The dynamic masking mechanism for the ceiling-mounted surveillance camera lens as described in claim 6, wherein: The dynamic shielding mechanism of the ceiling-mounted surveillance camera lens includes a second shielding part; the second shielding part is provided with at least one second sliding groove mating part and a second shielding plate; the first shielding part has at least one auxiliary sliding groove part; and the at least one second sliding groove mating part extends inward from the second shielding plate; the at least one second sliding groove mating part is movable relative to the at least one auxiliary sliding groove part.

8. The dynamic masking mechanism for the ceiling-mounted surveillance camera lens as described in claim 7, wherein: The dynamic shielding mechanism of the ceiling-mounted surveillance camera lens further includes an electric control unit, which has a control interface, a control unit, a first link, and a second link; and the control interface is connected to the control unit by either wired or wireless means, and the control unit can control at least one of the first link and the second link in order to control the movement of at least one of the first shielding part and the second shielding part.
