Description

Technical Field

[0001] This utility model relates to the field of surveillance cameras, and in particular to a multi-functional high-definition surveillance camera. Background Technology

[0002] Surveillance cameras are electronic devices used to collect image information of specific areas and are widely used in security, public place monitoring and intelligent management.

[0003] In existing technologies, traditional surveillance cameras generally adopt fixed installation or simple pan-tilt structure, which cannot actively sense and track the location of sound sources. This results in inadequate image capture when emergencies occur, making it difficult to collect evidence afterward and creating certain blind spots in monitoring. In addition, although traditional surveillance cameras can capture images in low light or nighttime environments, the images they acquire often suffer from low clarity and blurred details, making it difficult to identify target features and thus affecting the accuracy of monitoring.

[0004] Therefore, existing technologies have shortcomings and need to be improved. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a multi-functional high-definition surveillance camera that can capture clear images and automatically track the location of sound sources.

[0006] To achieve this objective, the present invention adopts the following technical solution: a multi-functional high-definition surveillance camera, comprising a rotating base, a U-shaped frame, a pitch motor, a slewing base, a camera module, a microphone array module, and a control circuit board;

[0007] The rotating base is connected to the bottom of the U-shaped frame. The rotating base is used to drive the U-shaped frame to rotate in the horizontal direction. The two ends of the rotary seat are rotatably connected to the U-shaped frame through rotating shafts. The pitch motor is located at one end of the U-shaped frame and connected to the rotary seat. The pitch motor is used to control the swing angle of the rotary seat in the pitch direction.

[0008] The camera module and the control circuit board are both located inside the rotary base. The camera module is used to capture monitoring images. The microphone array module is located at the front end of the rotary base. The microphone array module and the camera module are electrically connected to the control circuit board. The microphone array module is used to capture the direction of the sound source signal in the monitoring area. The control circuit board is used to control the pitch motor and the rotating base to drive the camera module to rotate in the direction of the sound source.

[0009] The rotary base is also equipped with a light intensity sensor and a supplementary light. The light intensity sensor and the supplementary light are electrically connected to the control circuit board. The light intensity sensor is used to detect the light intensity of the monitored area, and the supplementary light is used to provide illumination for the camera module when the light is insufficient.

[0010] The multi-functional high-definition surveillance camera using the above technical solution also includes a pitch limiting component. The pitch limiting component is located at the side end of the U-shaped frame and connected to the rotating shaft. The pitch limiting component is used to limit the swing angle of the rotating seat.

[0011] Using the above technical solution, in the multi-functional high-definition surveillance camera, the pitch limiting component includes a limiting pin and a limiting ring. The limiting ring is located at the side end of the U-shaped frame, and the limiting ring has an arc-shaped groove along the circumference. The limiting pin is connected to the rotating shaft, and the end of the limiting pin is located in the arc-shaped groove. The arc-shaped groove is used to limit the swing stroke of the limiting pin.

[0012] The multi-functional high-definition surveillance camera using the above technical solution also includes a speaker module, which is located on the back of the rotary base and is used to play voice information sent by an external mobile terminal.

[0013] The multi-functional high-definition surveillance camera using the above technical solution also includes a pitch gyroscope and an azimuth gyroscope, both of which are located within the rotary base. The pitch gyroscope is used to detect the swing angle of the camera module in the pitch direction, and the azimuth gyroscope is used to detect the rotation angle of the camera module in the horizontal direction.

[0014] In the above-described technical solution, the camera module of the multi-functional high-definition surveillance camera is an infrared camera.

[0015] The multi-functional high-definition surveillance camera using the above technical solution also includes a pitch locking pin. The U-shaped frame is provided with a positioning seat, and the positioning seat is provided with a threaded hole. The pitch locking pin is threadedly connected to the threaded hole and is used to abut against the side wall of the rotary seat as the pitch locking pin rotates.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] This invention enables the camera module to rotate in both horizontal and vertical directions through the coordinated operation of the rotating base, U-shaped frame, and swivel base. The microphone array module can sense the direction of the sound source signal in real time. Under the control of the control circuit board, the camera module can be automatically turned towards the sound source, thereby achieving automatic tracking and monitoring of abnormal sound sources and avoiding blind spots in monitoring. The swivel base integrates a light intensity sensor and a supplementary light. When the ambient light is insufficient, the control circuit board can trigger the supplementary light to provide auxiliary illumination, thereby improving the image acquisition clarity of the camera module and enhancing the recognition capability and low-light imaging effect of the surveillance camera.

Obviously, the embodiments described below are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0025] In the description of this utility model, it should be understood that the terms "upper," "lower," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component centrally located at the same time.

[0026] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0027] like Figures 1 to 4As shown, this utility model embodiment provides a multifunctional high-definition surveillance camera, including a rotating base 1, a U-shaped frame 2, a pitch motor 3, a swivel base 4, a camera module 5, a microphone array module 6, and a control circuit board 7. The rotating base 1 is connected to the bottom of the U-shaped frame 2, and the rotating base 1 is used to drive the U-shaped frame 2 to rotate in the horizontal direction. The two ends of the swivel base 4 are rotatably connected to the U-shaped frame 2 through rotating shafts. The pitch motor 3 is located at one end of the U-shaped frame 2 and connected to the swivel base 4. The pitch motor 3 is used to control the swing angle of the swivel base 4 in the pitch direction. The camera module 5 and the control circuit board 7 are both located inside the swivel base 4. The camera module 5 is used to capture surveillance images. The microphone array module 6 is located at the front end of the swivel base 4. The microphone array module 6 is electrically connected to the control circuit board 7. The microphone array module 6 is used to collect the direction of the sound source signal in the monitoring area. The control circuit board 7 is used to control the pitch motor 3 and the rotating base 1 to drive the camera module 5 to rotate in the direction of the sound source. When an abnormal sound source appears in the monitoring area, the microphone array module 6 can collect the sound source signal in real time and determine the approximate direction information of the sound source. The control circuit board 7 analyzes the direction of the sound source and issues a control command accordingly. This controls the rotating base 1 to drive the U-shaped frame 2 to rotate in the horizontal direction. Then, the pitch motor 3 drives the rotary seat 4 to adjust the angle in the pitch direction, so that the camera module 5 installed in the rotary seat 4 can automatically turn and position itself in the direction of the sound source. This achieves automatic acquisition and monitoring of the real-time image of the sound source location, improving the intelligent response capability and evidence collection reliability of the monitoring camera.

[0028] The rotating base 4 is also equipped with a light intensity sensor 81 and a supplementary light 82. The light intensity sensor 81 and the supplementary light 82 are electrically connected to the control circuit board 7. The light intensity sensor 81 is used to detect the ambient light intensity of the monitored area, and the supplementary light 82 is used to provide illumination for the camera module 5 when the light is insufficient. During operation, the light intensity sensor 81 can detect the ambient light intensity in the monitored area and transmit the detection signal to the control circuit board 7 for analysis and judgment. When the light intensity is lower than a preset threshold, the control circuit board 7 can turn on the supplementary light 82 to provide illumination for the camera module 5, thereby improving the image clarity in low light or nighttime environments, avoiding image blurring or loss of detail due to insufficient light, and improving the imaging quality and target recognition capability of nighttime monitoring images. It should be noted that the activation of the supplementary light 82 is triggered by the comprehensive judgment of the control circuit board 7 when the direction of the sound source needs to be turned to monitor and the current ambient light is insufficient, and it is not automatically activated in all low light conditions.

[0029] like Figure 3As shown, further, it also includes a pitch limiting component 31. The pitch limiting component 31 is located at the side end of the U-shaped frame 2 and connected to the rotating shaft. The pitch limiting component 31 is used to limit the swing angle of the rotary seat 4. The pitch limiting component 31 includes a limiting pin 311 and a limiting ring 312. The limiting ring 312 is located at the side end of the U-shaped frame 2 and has an arc-shaped groove 3120 along the circumference. The limiting pin 311 is connected to the rotating shaft, and the end of the limiting pin 311 is located in the arc-shaped groove 3120. The arc-shaped groove 3120 is used to limit the swing stroke of the limiting pin 311. This setting can prevent the rotary seat 4 from swinging excessively in the pitch direction, causing the camera module 5's viewing angle to deviate from the normal monitoring range.

[0030] like Figure 2 As shown, it further includes a speaker module 9, which is located on the back side of the rotary base 4. The speaker module 9 is used to play voice information sent by an external mobile terminal. When the monitoring camera is connected to the external mobile terminal through the communication module, the external mobile terminal can send voice signals to the device wirelessly. Then, the speaker module 9 can be driven by the control circuit board 7 to play the voice. In this way, the monitoring camera can realize functions such as voice broadcasting, remote intercom, and warning reminders.

[0031] As shown in the figure Figure 4 As shown, the system further includes a pitch gyroscope 32 and an azimuth gyroscope 33, both housed within the rotary base 4. The pitch gyroscope 32 detects the swing angle of the camera module 5 in the pitch direction, and the azimuth gyroscope 33 detects the rotation angle of the camera module 5 in the horizontal direction. When the camera module 5 rotates under the control of the control circuit board 7, the pitch gyroscope 32 detects the change in its swing angle along the pitch axis, and the azimuth gyroscope 33 detects its horizontal rotation angle around the vertical axis. This provides dynamic feedback on the current attitude of the camera module 5, preventing problems such as over-rotation, tracking deviation, or angle drift, and effectively improving the pointing adjustment accuracy of the camera module 5.

[0032] Furthermore, the camera module 5 is an infrared camera, which can acquire images in low light or completely no visible light environment, thereby realizing all-weather, uninterrupted video monitoring.

[0033] like Figure 2As shown, it further includes a pitch locking pin 34. The U-shaped frame 2 is provided with a positioning seat 21, and the positioning seat 21 is provided with a threaded hole. The pitch locking pin 34 is threadedly connected to the threaded hole and is used to abut against the side wall of the rotary seat 4 as the pitch locking pin 34 rotates. The user can manually rotate the pitch locking pin 34 to make it rotate in the direction of thread insertion and extend to abut against the side wall of the rotary seat 4, thereby realizing the mechanical locking effect on the rotary seat 4 and preventing the camera module 5 from shaking.

[0034] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
