For example, the first illuminance sensor 41 may be configured as a photosensitive sensor, such as a photo resistor, a photo diode, a photo transistor, a photomultiplier tube, or the like.

Specifically, the processor is a CPU of the camera, and is electrically connected to both the illumination assembly 30 and the first illuminance sensor 41, and the processor can control the illumination assembly 30 to be turned off according to a detection value of the first illuminance sensor 41. Here, since the light of the lighting assembly 30 hardly affects the detection of the first illuminance sensor 41, the detection value of the first illuminance sensor 41 can reflect the real ambient illuminance. Then, the processor controls the lighting assembly 30 to be turned off through the detection value of the first illumination sensor 41, so that the lighting assembly 30 can be turned off in time (when the lighting assembly 30 is turned on) in a day time to save energy.

Further, in the present embodiment, the camera further includes a housing 10, the first illuminance sensor 41 is disposed on a side portion of the housing 10, and a sensing side of the first illuminance sensor 41 faces away from the housing 10.

Specifically, the housing 10 is used to provide mounting positions for the camera module 20, the illumination module 30, the illuminance detection module 40, the processor, and the like. The housing 10 of the camera may be generally square, cylindrical, spherical, hemispherical, etc., and may be specifically adjusted according to actual needs, which is not specifically limited in the present application. Generally, the front end of the housing 10 is provided with the camera module 20, the lighting module 30, and the like, and the rear end of the housing 10 is generally provided with a mounting seat (not labeled), so that the first illumination sensor 41 is provided at the side of the housing 10, and the first illumination sensor 41 can be mounted without changing the basic structure of a conventional camera, which is beneficial to reducing the cost.

On the basis that the first illumination sensor 41 is disposed on the side portion of the housing 10, the sensing side of the first illumination sensor 41 faces away from the housing 10, so as to further facilitate avoiding the interference of the illumination assembly 30 on the first illumination sensor 41, and improve the accuracy of the first illumination sensor 41 in detecting the ambient illumination. Of course, the design of the present application is not limited thereto, and in other embodiments, the first illuminance sensor 41 may be disposed at the front end or the rear end of the housing 10.

It can be understood that, the first illumination sensor 41 is disposed in the accommodating cavity 11 inside the housing 10, on one hand, the first illumination sensor 41 is convenient to mount, and the integrity of the camera is improved; on the other hand, the first illuminance sensor 41 may be protected by the housing 10 based on the ambient illuminance detection performed by the first illuminance sensor 41. Of course, the design of the present application is not limited thereto, and in other embodiments, the first illuminance sensor 41 may be mounted on the outer side of the housing 10.

On the basis of the above embodiments, the camera of the present application further includes a light-transmissive side panel 50, and the light-transmissive side panel 50 is mounted on the sensing window. It can be understood that, the light-transmitting side panel 50 is installed on the sensing window, and on the basis of ensuring that the first illuminance sensor 41 detects the ambient illuminance sensor, protection such as water resistance and dust resistance is provided for the first illuminance sensor 41, so as to protect the first illuminance sensor 41.

Optionally, the side of the light-transmitting side panel 50 facing away from the first illuminance sensor 41 is disposed in an arc. Here, the side of the transparent side panel 50 facing away from the first illuminance sensor 41 is an outer side of the transparent side panel 50 (the side of the transparent side panel 50 facing the first illuminance sensor 41 is an inner side). It can be understood that the lateral surface with printing opacity side board 50 sets up to the cambered surface, and this cambered surface is favorable to landing such as rainwater, dew, dust to be favorable to reducing the attachment of printing opacity side board 50 lateral surface, promote the cleanliness factor of printing opacity side board 50, in order to do benefit to first illuminance sensor 41 and detect real environment illuminance. Of course, the design of the present application is not limited thereto, and in other embodiments, the outer side surface of the light-transmitting side panel 50 may be disposed in a plane or other shape.

Optionally, the periphery of the light-transmissive side panel 50 is sealingly connected with the periphery of the sensing window. It can be understood that, by hermetically connecting the periphery of the light-transmitting side panel 50 with the periphery of the sensing window, the waterproof sealing performance of the light-transmitting side panel 50 is improved, so as to improve the protection of the first illuminance sensor 41 and the inside of the housing 10.

Illustratively, the light-transmitting side panel 50 can be hermetically connected with the sensing window by means of a sealing rubber ring, a sealant, or the like; or a sealing structure (such as a containing sink groove, an installation caulking groove, etc.) can be arranged at the periphery of the sealing window for the light-transmitting side panel 50 to be installed in a sealing way; or a combination of the two sealing methods can be used to achieve the sealing connection between the transparent side panel 50 and the sensing window.

As shown in fig. 4 and 5, in another embodiment of the present application, the illuminance detection assembly 40 further includes a second illuminance sensor 42, the second illuminance sensor 42 is used for detecting ambient illuminance, and the sensing side of the second illuminance sensor 42 is oriented in the same direction as the direction of the camera assembly 20. The sensing side of the second illuminance sensor 42 refers to a side of the second illuminance sensor 42 that collects light. By setting the direction of the sensing side of the second illuminance sensor 42 to be the same as the direction of the camera module 20, the illumination of the imaging object of the camera module 20 can be detected more accurately by the second illuminance sensor 42.

For example, the second illuminance sensor 42 may be configured as a photosensitive sensor, such as a photo resistor, a photo diode, a photo transistor, a photo multiplier, or the like.

Correspondingly, the processor is also electrically connected with the second illumination sensor 42, and the processor is further configured to control the lighting assembly 30 to be turned on according to the detection value of the second illumination sensor 42. It is understood that the second illuminance sensor 42 can more accurately detect the illumination at the subject photographed by the camera assembly 20 than the first illuminance sensor 41. Then, the processor controls the illumination assembly 30 to be turned on according to the second illuminance sensor 42, so that the illumination assembly 30 can be turned on more timely, and the improvement of the imaging quality of the camera and the energy saving can be achieved.

For example, in a dark condition (dark environment), if the ambient illumination of the shooting object of the camera module 20 is high (for example, there are light sources such as a street lamp and a decorative lamp), the camera module 20 can acquire a color image without turning on the illumination module 30, and the processor can select not to turn on the illumination module 30 according to the detection value of the second illumination sensor 42, so as to save energy.

Further, the processing logic of the processor will be explained in conjunction with the first illumination sensor 41 and the second illumination sensor 42.

Specifically, the processor determines whether it is dark or not based on the detection value of the second illumination sensor 42 when the lighting assembly 30 is not turned on, and controls the lighting assembly 30 to be turned on based on the detection value of the second illumination sensor 42 when an alarm event is detected at night. Heretofore, the first illuminance sensor 41 may be in a sleep state or an off state from the viewpoint of energy saving (of course, the first illuminance sensor 41 may also be in an active state, but the processor does not receive or process the detection data of the first illuminance sensor 41). When the lighting assembly 30 is turned on, the second illumination sensor 42 enters a sleep state or an off state (of course, the second illumination sensor 42 may also be in an active state, but the processor does not receive or process the detection data of the second illumination sensor 42), and at this time, the processor determines whether to be bright or not according to the detection value of the second illumination sensor 42, and turns off the lighting assembly 30 in time. )

It can be understood that, the first illumination sensor 41 and the second illumination sensor 42 are used in cooperation, so that the camera of the present application further improves the energy saving effect on the premise of ensuring the imaging capability of the camera assembly 20 in the dark environment.

Further, a mounting cavity 12 is formed in the housing 10 of the camera, a monitoring port 13 communicating with the mounting cavity 12 is provided at the front end of the housing 10, and the image pickup unit 20, the illumination unit 30, and the second illuminance sensor 42 are all provided in the mounting cavity 12 and all face the monitoring port 13. It can be understood that, the arrangement can provide protection for the camera module 20, the illumination module 30 and the second illumination sensor 42 through the housing 10, and is beneficial to the arrangement of the camera module 20, the illumination module 30 and the second illumination sensor 42 in the same direction, so as to improve the integrity of the camera.

On the basis of the above embodiment, the camera further includes a light-transmissive front panel 60, and the light-transmissive front panel 60 is mounted to the monitoring port 13. It can be understood that the transparent front panel 60 can provide protection against water, dust, etc. for each component/part in the installation cavity 12 on the basis of ensuring the normal operation of the camera module 20, the illumination module 30 and the second illuminance sensor 42, so as to protect the component/part in the installation cavity 12.

Further, the front end of the housing 10 protrudes from the front panel to form a shielding ledge 14. It can be understood that the shielding convex edge 14 can not only provide protection such as water resistance and dust resistance for the light-transmitting front panel 60 to ensure the light transmission of the light-transmitting front panel 60, but also limit the light irradiation direction of the illumination assembly 30 to a certain extent, thereby further avoiding the interference of the light of the illumination assembly 30 to the first illumination sensor 41.
