## Background
BACKGROUND
1. Technical Field
The present disclosure relates to surveillance apparatuses and, particularly, to a surveillance apparatus having manually adjustable fixed view image pick-up device.
2. Description of Related Art
Generally, fixed view security cameras are mounted to a permanent fixture and manually adjusted for a desired viewing angle during install. Presently, adjustments to aim an image pick-up device involve rotating the pick-up device about two axes, which does not allow for the most accurate adjustments. Further, the adjustable mechanisms involved are complicated and not easily manipulated, which is inconvenient for users.
What is needed therefore, is a surveillance apparatus which can ameliorate the above-described limitations.

DETAILED DESCRIPTION
Referring to FIG. 1 and FIG. 2, a surveillance apparatus 100, according to an embodiment, includes a holder 10, a first adjusting member 20, an image pick-up device 30, a second adjusting member 40, and a third adjusting member 50, and a plurality of screws 35 and 36. The first adjusting member 20 is rotatably mounted to the holder 10. The second adjusting member 40 is rotatably mounted to the third adjusting member 50. The third adjusting member 50 is engaged with the first adjusting member 20.
The holder 10 has a generally hollow cylinder configuration and defines a circular opening 102 and a first through holes 103 equidistantly distributed around the opening 102. The opening 102 includes a circular stepped groove 104 which has a lower groove (not labeled) and an upper groove (not labeled) formed above the lower groove.
The first adjusting member 20 includes a first annular plate 21 and two extending portions 22 diametrically extending upward from the first annular plate 21. The two extending portions 22 are substantially parallel to each other. Each extending portion 22 defines a second through hole 201 therein adjacent to a distal end. The two second through holes 201 are aligned with each other. The outer diameter of the first annular plate 21 is substantially equal to the inner diameter of the upper groove of the stepped groove 104, and the first annular plate 21 is rotatably seated in the upper groove.
Referring to FIG. 3, the image pick-up device 30 includes a base plate 31, an image sensor 32, and a lens module 33. The image sensor 32 is electrically disposed on the base plate 31 and optically coupled with the lens module 33. The base plate with a sixth through holes (not labeled).
The second adjusting member 40 includes a second annular plate 41 and a third annular plate 42. The third annular plate 42 coaxially extends upward from the second annular plate 41. The second adjusting member 40 defines four third through holes 420 running through the second and third annular plates 41 and 42. The outer periphery of the second annular plate 41 is toothed with an equivalent scale. The image pick-up device 30 is received in the third annular plate 42. The second adjusting member 40 is mounted to the base plate 31 by screwing four screws 35 from the bottom side of the base plate 31 through the third through holes 420 and into the base plate 31. The lens module 33 defines a fourth through holes (not labeled) at a bottom portion and is fixed to the base plate 31 by running the screws 35 through the fourth through holes of the lens module 33 and the sixth through holes of the base plate 31 from the bottom side of the base plate 31.
The third adjusting member 50 includes a fourth annular plate 51, a pair of handles 52, and two fasteners 53. The inner diameter of the fourth annular plate 51 is substantially equal to the outer diameter of the third annular plate 42. The thickness of the fourth annular plate 51 along an axis direction thereof is substantially equal to that of the third annular plate 42. The fourth annular plate 51 sleeves on the third annular plate 42. The handles 52 diametrically extend upward from opposite sides of the fourth annular plate 51, and each defines a fifth through hole 520 corresponding to the second through hole 201. The fourth annular plate 51 has a position indicator 510. The relative position between the lens module 33 and the third adjusting member 50 can be exactly indicated by the position indicator 510 according to which of teeth 410 formed on the outer periphery of the second annular plate 41 the position indicator 510 is aligned with during rotating the lens module 33 relative to the third adjusting member 50.
When assembling the surveillance apparatus 100, the image sensor 32 is electrically connected to and mounted on the base plate 31, and the lens module 33 is fixed to the base plate 31 and aligned with the image sensor 32. The third annular plate 42 of the second adjusting member 40 is fixed to the base plate 31 by the screws 35 from the bottom side of the base plate 31, and the fourth annular plate 51 rotatably sleeves on the third annular plate 42 and seats on the second annular plate 41 with the screws 35 pressing on the forth annular plate 51. The fifth through holes 520 of the third adjusting member 50 are aligned with the second though holes 201 of the extending portions 22. Then the third adjusting member 50 and the first adjusting member 20 are assembled together by the fasteners 53. As such, the third adjusting member 50 is pivotably attached to the first adjusting member 20 by screws 53. The first adjusting member 20 seats in the stepped groove 104, and is secured on the holder 10 by the screws 36 extending through the first through holes 103 and pressing on the first annular plate 21. It can be understood that the image pick-up device 30 can be rotated about the axis C (Referring to FIG. 3) of the fifth through holes 520 during assembly to a desired position.
After the surveillance apparatus 100 is assembled, to make further adjustments, the screws 36 can be loosened, and the image pick-up device 30 rotated about the axis A of the holder 10 to a desired position. To adjust the image pick-up device 30 by rotating it about the axis B the screws 35 pressing on the fourth annular plate can be loosened.
It is to be understood, however, that even though numerous characteristics and advantages of the disclosure have been set forth in the foregoing description, together with details of the structures and functions of the embodiment(s), the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
