Description

Technical Field

[0001] This utility model relates to the field of security camera technology, and in particular to an adjustable security camera device. Background Technology

[0002] In today's society, the importance of security monitoring is becoming increasingly prominent. It is widely used in various places, such as shopping malls, schools, office buildings, and transportation hubs, and plays a key role in ensuring public safety and maintaining social order. As the core equipment of security monitoring systems, the performance of security cameras directly affects the monitoring effect.

[0003] Traditional security cameras are mostly fixed installations, and the shooting height and angle are difficult to adjust after installation. However, in practical applications, different people have different heights, which poses a challenge to security monitoring based on facial recognition. For example, in access control systems for personnel access management, if the camera is installed at a low height, it may only capture the part below the forehead of taller people, resulting in incomplete facial images and reducing the accuracy and efficiency of facial recognition.

[0004] Therefore, developing an adjustable security camera device is of great practical significance. By adjusting the height of the camera components, it can adapt to the shooting needs of people of different heights, improve the efficiency of facial recognition, and enhance the flexibility and effectiveness of security monitoring. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an adjustable security camera device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An adjustable security camera device includes a support assembly. A sleeve is fixed to the top of the support assembly, and a rotary motor is fixed to the bottom of the sleeve. The output end of the rotary motor is connected to a lead screw via a coupling. A fixing member is movably connected to the top of the sleeve, and a camera assembly is fixed to the top of the fixing member. The fixing member and the lead screw work together. A control button electrically connected to the rotary motor is installed on the side wall of the sleeve.

[0008] As a further embodiment of this utility model: the support assembly includes a mounting base and a support base, the mounting base and the support base are fixedly welded together by an intermediate plate, and the mounting base and the outer circumferential wall of the sleeve are fixedly connected.

[0009] As a further embodiment of this utility model: the fixing component includes a lifting rod and a limiting plate. The limiting plate is integrally formed on the side wall of the lifting rod, and the lifting rod, the limiting plate and the sleeve are movably connected. A nut that matches the lead screw is installed inside the lifting rod.

[0010] As a further embodiment of this utility model: the camera assembly includes a mounting shell and a security camera. The mounting shell is fixed to the top of the lifting rod, and the security camera is fixed to the outer wall of one side of the mounting shell. A display screen and a lighting lamp are installed on the outer wall of one side of the mounting shell.

[0011] As a further embodiment of this utility model: a turntable is movably connected to the outer circumference of the sleeve, a blocking plate is fixed to the side wall of the turntable, and a protective shell is fixed to the outer circumference of the sleeve.

[0012] As a further improvement of this utility model, a toothed ring is fixed by a pin at a position on the inner circumference of the sleeve near the inside of the protective shell.

[0013] As a further improvement of this utility model: a drive motor is fixed to the outer wall of the top of the turntable, and a gear that meshes with the gear ring is fixed to the output end of the drive motor by a pin.

[0014] As a further improvement of this utility model, the support base is provided with mounting holes.

[0015] Compared with the prior art, this utility model provides an adjustable security camera device, which has the following beneficial effects:

[0016] 1. Through the coordinated design of the rotary motor, lead screw, lifting rod, and limit plate, along with control buttons, the height of the camera component can be flexibly adjusted. Security personnel can quickly and accurately adjust the camera component to the appropriate height for individuals of different heights, ensuring that the security camera can clearly capture facial images and effectively improving facial recognition efficiency.

[0017] 2. The security camera captures and transmits real-time monitoring footage to the display screen, allowing security personnel to intuitively view the dynamics of the monitored area; the lighting automatically or manually turns on when there is insufficient light, providing sufficient light for the camera to capture facial images and ensuring image quality.

[0018] 3. Before facial recognition, the barrier is placed in front of the person to provide initial obstruction; when the security camera recognizes the person whose face has been registered, the processing mechanism controls the drive motor to drive the gear to rotate, so that the barrier rotates and no longer blocks the person from passing through. After the person passes through, the barrier automatically resets.

[0019] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on this utility model.

[0027] Example 1:

[0028] An adjustable security camera device, in order to improve adjustment flexibility, such as Figures 1 to 4 As shown, the device includes a support assembly. A sleeve 2 is fixed to the top of the support assembly, and a rotary motor 11 is fixed to the bottom of the sleeve 2 by screws. The output end of the rotary motor 11 is connected to a lead screw 16 via a coupling. A fixing component is slidably connected to the top of the sleeve 2, and a camera assembly is fixed to the top of the fixing component. The fixing component includes a lifting rod 6 and a limiting plate 8. The limiting plate 8 is integrally formed on the side wall of the lifting rod 6, and the lifting rod 6, the limiting plate 8, and the sleeve 2 are slidably connected. A lead screw nut adapted to the lead screw 16 is installed inside the lifting rod 6. A control button 10 electrically connected to the rotary motor 11 is installed on the side wall of the sleeve 2.

[0029] The camera component can capture and recognize faces. It can then compare and analyze facial images against a pre-set facial database using deep learning and other technologies to determine if the person is authorized. Since people undergoing facial recognition vary in height, to improve efficiency, when the camera component is low, taller individuals can control the rotary motor 11 via control button 10. The rotary motor 11 drives the lead screw 16 to rotate, causing the lifting rod 6 to rise along the sleeve 2 under the guidance of the limit plate 8, thus simultaneously raising the camera component for facial recognition. Similarly, when the camera component is high and the individual is short, control button 10 controls the rotary motor 11 to drive the lead screw 16 to rotate in the opposite direction, causing the lifting rod 6 to move downwards along the sleeve 2 under the guidance of the limit plate 8, thereby lowering the camera component's height. In this embodiment, moving the control button upwards controls the lifting rod 6 to move upwards along the sleeve 2, and moving the control button downwards controls the lifting rod 6 to move downwards along the sleeve 2. The switch control is a mature existing technology and will not be elaborated further here.

[0030] The support assembly includes a mounting base 1 and a support base 12. The mounting base 1 and the support base 12 are welded and fixed together by an intermediate plate 13, and the mounting base 1 and the outer circumferential wall of the sleeve 2 are fixedly connected by bolts.

[0031] The entire device can be supported by the support base 12. The support base 12 has mounting holes. When the support base 12 needs to be fixed to the ground, the expansion bolts are passed through the mounting holes and hammered into the pre-drilled holes in the ground. The nuts are then tightened to fix the support base 12 to the ground.

[0032] The camera assembly includes a mounting housing 5 and a security camera 18. The mounting housing 5 is fixed to the top of the lifting rod 6 by bolts, and the security camera 18 is fixed to the outer wall of one side of the mounting housing 5. A display screen 17 and a lighting lamp 19 are installed on the outer wall of one side of the mounting housing 5.

[0033] The security camera 18 displays and monitors real-time images. The security camera 18 transmits images to the display screen 17. The lighting lamp 19 assists in face capture. When the light is insufficient, the lighting lamp 19 is turned on to assist the camera in capturing images. The security camera 18 extracts face images. The mounting shell 5 contains a processing mechanism that extracts face images from the video stream captured by the camera. By comparing and recognizing face features, the extracted image is compared with the database. Successful face recognition is displayed, and failure to recognize the face is detected by issuing an alarm. Face recognition is an existing technology and will not be described in detail here.

[0034] Working principle: First, the device is securely installed on the ground using the support base 12 and expansion bolts; the control button 10 controls the rotary motor 11 to drive the lead screw 16 to rotate, causing the lifting rod 6 to rise and fall along the sleeve 2 under the guidance of the limit plate 8, thereby adjusting the height of the camera assembly to accommodate people of different heights; the security camera 18 captures and monitors the scene in real time and transmits it to the display screen 17; when the light is insufficient, the lighting lamp 19 is turned on to assist in the acquisition; the processing mechanism inside the mounting shell 5 extracts the face image from the video stream captured by the camera and compares it with the preset database. If successful, the identity information is displayed as correct; if unsuccessful, an alarm is issued.

[0035] Example 2:

[0036] An adjustable security camera device, such as Figures 1 to 4 As shown, in order to improve the security effect, this embodiment makes the following additions based on embodiment 1: the outer circumference of the sleeve 2 is fixed with a protective shell 3 by bolts, and the outer circumference of the sleeve 2 is rotatably connected with a turntable 4. The side wall of the turntable 4 is fixed with a barrier plate 7 by screws. The inner circumference of the sleeve 2 is fixed with a gear ring 14 by pins near the inside of the protective shell 3. The top outer wall of the turntable 4 is fixed with a drive motor 9 by screws, and the output end of the drive motor 9 is fixed with a gear 15 that meshes with the gear ring 14 by pins.

[0037] In actual use, guardrails and other barrier mechanisms are set on both sides of the entire device. Before face recognition, the barrier plate 7 blocks the way for people. After the security camera 18 performs face recognition, if the face recognized by the security camera 18 has been registered and authorized, the processing mechanism set in the mounting shell 5 controls the drive motor 9 to drive the gear 15 to rotate. During the rotation, the gear 15 rotates along the outer wall of the tooth ring 14, so that the barrier plate 7 no longer blocks people during the rotation, allowing people to pass through. By integrating hardware timer chips such as timers in the device's circuit control system, the barrier plate 7 sends a trigger signal to the timer after rotation. After the timer starts counting and reaches the preset time, it outputs a control signal to the processing mechanism. The processing mechanism controls the drive motor 9 to drive the gear 15 to rotate in the opposite direction, thereby resetting the barrier plate 7.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
