And other extended hardware modules, such as SPK module, PIR module, laser module, etc., can be further set. In the example shown in FIG. 11 , the first SPK module 31 is arranged in the accommodating cavity 30 . The accommodating cavity 30 is located above the installation space, which can conveniently fill light for the dome camera 1 without affecting the installation on the upper wall of the bracket, and simultaneously realize the effect of waterproof and sunshade for the dome camera 1.

Further, the accommodating cavity 30 is not only used to provide a setting space for the hardware expansion module, but also is used to provide a hiding space for the cables of the dome camera 1 .

As shown in Figure 10 and Figure 11, the first component 10 includes:

a bottom plate 11, the bottom plate 11 forms a first surface for mounting the dome camera 1;

The side wall 12 , the side wall 12 extends vertically upward from the periphery of the bottom plate 11 in a direction away from the installation space to enclose the bottom plate 11 to form a receiving cavity 30 , the side wall 12 includes: a first end located at the first component 10 The rear sidewall 121 of 10a, the two first sidewalls 122 that are in contact with both ends of the rear sidewall 121 and are perpendicular to the rear sidewall 121, and the arcuate sidewall 123 located at the second end 10b of the first component 10, Both ends of the arc-shaped side wall 123 are respectively connected with the two first side walls 122, the arc-shaped side wall 123 and/or the first side wall 122 are provided with a fill light window 41, and the fill light lamp assembly 40 is adjacent to the fill light window 41;

The cover plate 13 is in contact with the top peripheral edge of the side wall 12 to cover the accommodating cavity 30 . A sealing ring 15 may be further disposed between the cover plate 13 and the top peripheral edge of the side wall 12 .

The first component 10 for realizing the ceiling installation of the dome camera 1 in this embodiment not only includes the first surface (the bottom plate 11 ) for installing the dome camera 1 , but also is further formed by enclosing the side wall 12 and the bottom plate 11 . The accommodating cavity 30 used for hardware expansion, the accommodating cavity 30 is located above the installation space, which can easily fill light for the dome camera 1 without affecting the upper wall installation of the bracket, and synchronously realizes the dome camera 1. The role of waterproof sunshade.

Among them, the monitoring area of the dome camera 1 is mainly located in front of the installation space, that is, on the side of the second end 10b of the first component 10. Therefore, as shown in FIG. 10 on the arcuate sidewall 123 of the second end 10b. However, according to the distribution of the monitoring area of the dome camera 1 , as shown in FIG. 13 , the supplementary light window 41 may be further arranged at the front end of the two first side walls 122 (the side facing the second end 10 b ) or the entire range , to fill light for the monitoring areas located in front of and on both sides of the installation space. Correspondingly, the number of the supplementary light assemblies 40 can be increased simultaneously. Wherein, the supplementary light window 41 can be in the shape of, for example, a circular racetrack.

In one embodiment, the light-filling window 41 and the side wall 12 are integrally two-color injection molded, and the light-filling window 41 is formed of a light-transmitting non-transparent material. In some embodiments, the fill light window 41 can be made of transparent PC+0.3‰ titanium dioxide material, which can not only pass through the fill light effectively, but also prevent the internal structure of the first component 10 from being directly seen through the opaque material. Wherein, the supplementary light window 41 on the bracket can have uniform light performance, so that it looks like a long strip of light with uniform light, so that the overall appearance effect is better.

Specifically, as shown in FIG. 4 , the fill light assembly 40 includes:

The fixed sheet metal 42 is fixed into the accommodating cavity 30,

One or more light boards 43 are mounted on the fixed sheet metal 42 , and the plurality of light boards 43 are symmetrically arranged in the accommodating cavity 30 with respect to the central axis of the arc-shaped side wall 123 .

Wherein, each bracket may include only one fixed sheet metal 42 , or may include multiple fixed sheet metals 42 , and one or more light panels 43 may be mounted on each fixed sheet metal 42 . For example, in the embodiment shown in FIG. 11 , the fill light assembly 40 includes two fixed sheet metals 42 , and each fixed sheet metal 42 is provided with a light plate 43 , and the two light plates 43 are about the arc-shaped side wall 123 . The central axis of the set is symmetrical. In some examples, at least two light panels 43 are installed on the bracket to achieve a fill light distance of 5 meters, so as to meet the fill light requirement of the dome camera.

Wherein, in order to achieve a uniform light-filling effect, in some embodiments, as shown in FIG. 6 , the lamp panel 43 and the light-filling window 41 are located on concentric circles. For example, the diameter of the side wall where the supplementary light window 41 is located is 160 mm, and the lamp panel 43 is on a concentric circle that is consistent with the center of the supplementary light window 41, and its diameter is 145 mm.

In some embodiments, as shown in FIG. 4 , the fill light assembly 40 further includes:

The polarized lamp cup 44 is installed on the lamp board 43 to adjust the reflection range of the light emitted from the lamp board 43 outside the installation space.

As shown in FIG. 14a, the light emitted from the light panel 43 may be reflected to the camera through the diffuse reflection of the ceiling, thereby causing light leakage in the picture. This is because the angle between the outgoing light and the ceiling is too small. In some embodiments, the exit angle of the lamp beads on the lamp board 43 is adjusted by the polarized lamp cup 44 to increase the angle between the lamp bead and the ceiling, which is shown as downward adjustment in FIG. ceiling, so that the reflection range of the outgoing light after being reflected by the ceiling will not fall into the installation space, that is, it will not form the fill light incident to the camera, but will be directly directed into the monitoring area of the camera, so as to realize the hemispherical Uniform fill light of camera 1.

The fill light assembly 40 is not limited to visible light fill light, but can also be infrared fill light. When the infrared fill light is used, the bracket structure of this solution can also improve the influence of infrared fill light leakage on the camera sensor.

Since the first assembly 10 and the second assembly 20 have cavities for hiding cables and setting hardware expansion modules, for the consideration of waterproof performance, when the first installation hole 51 or the second installation hole 52 is not used, that is, the dome camera When the 1 is not installed on the installation surface where it is located, the first knob 53 or the second knob 54 can be used to seal the internal cable storage space to prevent water and dust from entering it.

The wire hiding cavity 21 is located on the side of the second component 20 away from the installation space, and communicates with the accommodating cavity 30 to realize the function of hiding the wire. Since the wire hiding cavity 21 of the second component 20 only has the function of hiding wires, its thickness is much smaller than the thickness of the accommodating cavity 30 .

On the basis of setting the wire hiding cavity 21, in order not to affect the installation of the bracket on the upper wall, as shown in FIG. 15, the bracket of this embodiment may further include an adapter sheet metal 60, and the adapter sheet metal 60 is installed on the vertical wall , the second component 20 is detachably connected with the adapter sheet metal 60 .
