An embodiment of the utility model provides a camera device.

Referring to fig. 3 to 5, in an embodiment, the image capturing apparatus includes a housing 100, a cover plate 200, and an image capturing device 300. Wherein, the housing 100 has an installation cavity 110 with an opening; the cover plate 200 comprises a substrate 210 and a coating layer 220, the substrate 210 is made of a light-transmitting material and covers the opening of the installation cavity 110, the coating layer 220 is coated on the substrate 210, and the coating layer 220 is only used for infrared light with a wave band of 940nm to penetrate through; the camera module 300 is arranged in the installation cavity 110 and comprises a camera 310 and an infrared lamp 320 arranged on the periphery of the camera 310, the light emitting surfaces of the camera 310 and the infrared lamp 320 face the cover plate 200, and the coating layer completely covers the camera 310 and the infrared lamp 320.

Based on the structural design, in the embodiment, the camera device can be embedded into a wall body and other equipment, at this time, because the cover plate 200 with the coating layer is covered in front of the camera 310, and the coating layer only allows 940nm infrared light which cannot be observed by human eyes to pass through, the complete invisibility of the camera device can be realized. In other words, the camera 310 of the camera device can acquire 940nm infrared light penetrating through the cover plate 200 to realize a shooting function, but human eyes cannot observe light with a wavelength of 940nm, so people cannot see the camera 310 and the infrared lamp 320 behind the cover plate 200, and the cover plate 200 reflects the light seen by the human eyes, so that the camera device looks like a mirror from the outside, and complete invisibility of the camera 310 and the infrared lamp 320 is realized. Moreover, because the camera device is provided with the infrared lamp 320 for supplementing the ambient light, the camera device can be competent for shooting tasks under any illumination scene, including daytime scenes or dark scenes, so that the camera 310 and the infrared lamp 320 are completely covered by the coating layer on the cover plate 200, people can not see red light to see the camera 310 or the camera 310 in daytime when the infrared lamp 320 emits light at night, and all-weather invisibility can be realized.

It should be noted that the substrate is made of hard transparent material, and in this embodiment, the substrate 210 is preferably made of transparent glass, and the coating layer is disposed on the front plate surface and/or the rear plate surface of the substrate 210. Of course, in other embodiments, the substrate 210 may be made of other hard transparent materials, such as but not limited to optical grade acrylic plate, but in this embodiment, the transparent glass has the advantages of low cost and high light transmittance. Here, it is preferable that the plating layer is entirely coated on the rear plate surface of the substrate 210 facing the camera 310 in order to prevent contamination or damage of the plating layer, and the plating layer may be coated on the substrate 210 by, but not limited to, vacuum coating, and the like, and may realize a function of transmitting only infrared light of 940 nm.

Further, as shown in fig. 1 to 3, in the present embodiment, the cover plate 200 is attached to the front end surface of the open end of the housing 100, and the cover plate 200 extends outward to protrude out of the outer peripheral side surface of the housing 100. In other words, the cover plate 200 can not only completely cover the opening of the housing 100, but also the edge thereof protrudes out of the peripheral side surface of the housing 100, so that the housing 100 and the camera module 300 behind the cover plate 200 can not be seen from the front direction, and when the camera module is slightly deviated from the front direction, the protruding edge of the cover plate 200 can also play a role of covering, thus the camera device can be hidden when being observed from multiple angles, and the camera device is more suitable for actual installation occasions.

Referring to fig. 3 to 5, in the present embodiment, the image capturing apparatus further includes a first mounting plate 410 and a second mounting plate 420 both disposed in the mounting cavity 110, the first mounting plate 410 and the second mounting plate 420 are spaced back and forth along a direction toward the cover plate 200, the second mounting plate 420 is mounted with the image capturing component 300, and the first mounting plate 410 is located at the periphery of the camera 310 and is fixedly provided with a plurality of infrared lamps 320. Here, the edges of the first mounting plate 410 and the second mounting plate 420 may be connected to the inner wall surface of the mounting cavity 110 by means of brackets, slots, or adhesives, so as to perform positioning and mounting functions on the respective components, and thus, it is ensured that the camera 310 and the infrared lamp 320 are mounted at the correct positions and operate normally. In addition, as shown in fig. 3, in the present embodiment, it is preferable that the first mounting plate 410 and the second mounting plate 420 are both spaced and parallel to the cover plate 200, and the front end surface of the camera 310 facing the cover plate 200 is also spaced and parallel to the cover plate 200, so that more 940nm infrared light energy penetrating through the cover plate 200 can enter the camera 310 along the optical axis direction of the camera 310, and a better shooting effect is obtained.

Further, as shown in fig. 4 and 5, in the present embodiment, the first mounting plate 410 has a ring shape, and has a through hole 411 surrounded by an inner ring surface, and the front end of the camera 310 passes through the through hole 411. Thus, the infrared light emitted by the infrared lamp 320 is mainly distributed among the first mounting plate 410, the front end of the camera 310 and the inner plate surface of the cover plate 200, and the camera 310 can be more efficiently supplemented with light for the environment. In addition, in order to facilitate the installation and heat dissipation of the camera head 310, a space is provided between the inner ring surface of the first installation plate 410 and the outer circumferential side surface of the camera head 310.

Further, in the present embodiment, the plurality of infrared lamps 320 are preferably evenly spaced on the first mounting board 410. As shown in fig. 4 and 5 in particular, the number of infrared lamps 320 is four, i.e., one infrared lamp 320 is mounted on the first mounting board 410 every ninety degrees. However, in other embodiments, the number and the position distribution of the infrared lamps 320 can be designed according to actual requirements, and are not limited herein.

In particular, in this embodiment, the infrared lamp 320 is preferably a red explosion-free infrared lamp 320 that emits 940nm infrared rays, and is particularly preferably a L ED lamp, so that active light emission of the red explosion-free infrared lamp 320 can increase light intensity, thereby achieving the purpose of supplementing light to the environment and increasing the illumination of the photographed image, and further increasing the concealment of the camera device because the 940nm red explosion-free infrared lamp 320 cannot be seen by naked eyes from the outside, compared with the current common invisible camera, the light source in the daytime is from the environment, and the light source at night is from the environment and the infrared L ED lamp set.

Further, in the present embodiment, the camera assembly 300 further includes an image sensor (not shown) located on a side of the camera head 310 away from the cover plate 200, and the sensor is preferably a black light level or star light level image sensor. It can be understood that when the intensity of the infrared lamp 320 is insufficient, if the camera 310 is used with a black level or starlight level image sensor, the overall brightness of the picture can be increased under the weak illumination condition, and a better shooting effect can be obtained.

Further, in the present embodiment, a heat insulating layer made of a heat insulating material is provided between the cover plate 200 and the camera 310. It can be understood that, because the camera 310 generates heat during operation, the heat insulating layer made of heat insulating material is arranged between the cover plate 200 and the camera 310, so that the cover plate 200 can keep consistent with the ambient temperature, the camera 310 can be found without sensing the temperature by touch, and the concealment of the camera device is further improved.

Finally, it should be noted that, in this embodiment, the camera device further includes a main control board (not shown) and a WIFI module (not shown) both disposed in the installation cavity 110 and used for receiving and transmitting information, the main control board is disposed on one side of the installation cavity 110 far away from the cover plate 200, and the camera module 300 and the WIFI module are both electrically connected to the main control board, so that data transmission through WIFI can be implemented.

The above description is only exemplary of the present application and should not be taken as limiting the present application, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present application should be included in the protection scope of the present application.
