Description

Technical Field

[0001] This application relates to the field of security equipment technology, and in particular to a multi-functional security equipment device for smart property management. Background Technology

[0002] In modern property management systems, "security and prevention" is the core element in ensuring the personal and property safety of residents. "Security" means avoiding danger, preventing harm, and preventing accidents; "prevention" encompasses advance preparation to deal with potential attacks and proactive vigilance to achieve effective protection. Together, these constitute the core objectives of property security work. Among the various security equipment in property management, CCTV systems, alarm control systems, and remote image transmission equipment are indispensable. Surveillance cameras, as the key carriers for directly acquiring on-site image information, occupy a fundamental and irreplaceable position. Ensuring the stable operation of surveillance cameras in important sections and areas such as entrances and exits, main roads, parking lots, and building lobbies within the community, achieving comprehensive, 24 / 7 image acquisition, has become a basic requirement and essential guarantee for modern property management. However, the widely used security monitoring equipment for property management generally suffers from limited functionality. Most devices can only perform basic shooting and real-time monitoring functions, lacking proactive defense and intelligent response capabilities against malicious damage or obstruction. Because property security personnel cannot continuously monitor all surveillance footage 24 / 7, such obstruction often goes undetected, causing the monitoring equipment to "fail" during critical periods. This allows criminals to escape recording, posing a significant threat to community security and greatly diminishing the protective effectiveness of the property management security system. To address the issue of easily obstructed surveillance equipment, targeted improvements have emerged in related technical fields. For example, Chinese Patent CN113095961A discloses a "Multifunctional Security Equipment Device for Smart Property Management." This device, by installing a camera inside its casing and configuring a roller and horizontal plate on the left side of the upper surface of the casing, along with fan blades and dustproof nets, aims to remove objects that obstruct the camera, thereby preventing criminals from evading surveillance by obstructing the camera. In terms of application effectiveness, this device can achieve a certain degree of protection and removal for larger obstructions such as fabric, compensating for the shortcomings of traditional surveillance equipment to some extent. However, a deeper analysis of its practical application scenarios reveals significant shortcomings and limitations in protection. Its core design is only effective against large, easily removable objects like clothing and fabrics using mechanical structures such as rollers and fan blades. It lacks an effective mechanism to deal with small, highly adhesive objects such as chewing gum, transparent tape, and self-adhesive stickers. When such sticky objects adhere directly to the camera lens, the existing device's rollers and crossbars cannot quickly and thoroughly remove them, resulting in continuous lens obstruction and hindering the normal operation of the monitoring function. This demonstrates that existing property security monitoring equipment is significantly inadequate in protecting against malicious obstruction, especially against small, sticky objects, failing to meet the modern community's demand for 24 / 7, comprehensive, and highly reliable security monitoring. Therefore, further optimization and improvement of the anti-obstruction structure and functions of existing property security monitoring equipment are urgently needed to enhance its overall protective performance and effectively ensure the community's security system.

[0014] In summary, this application includes the following beneficial technical effects: 1. During the application of this technical solution, by setting up a structure that coordinates the controller, timing module, anti-obstruction module, and secondary camera, it enables automatic detection of obstructions, delayed activation of anti-obstruction actions, and backup monitoring linkage during use. When the main camera is obstructed, the ToF sensor transmits a signal to the controller, and the timing module delays the activation of relevant components, allowing time for criminals to leave and preventing the components from being detected immediately. This improves the actual security practicality of the equipment and solves the problem in existing technologies where monitoring equipment is easily detected and further damaged by criminals due to obstruction actions, leading to security failure. At the same time, the tilting of the photovoltaic panel is set to power each component, reducing the equipment's dependence on external power and solving the problem of excessive power consumption and dependence on external power in the operation of existing equipment. 2. During the application of this technical solution, by setting up a structure that links the anti-obstruction module with the secondary camera mechanism, effective measures can be taken to deal with different obstructions during use. For larger obstructions such as cloth, the obstruction pusher can directly push them away from the lens; for smaller sticky obstructions such as chewing gum, if they cannot be removed by pushing, the secondary camera module can move and adjust its angle in time to capture images of the original monitoring area. This achieves the effect of comprehensively dealing with various obstructions and ensuring uninterrupted monitoring. It solves the problem that existing monitoring equipment can only deal with large-volume obstructions and cannot handle small sticky obstructions, resulting in monitoring failure after obstruction. 3. During the application of this technical solution, the structure of the internal movable module, linkage module and the auxiliary camera module allows the auxiliary camera mechanism to flexibly complete position movement and angle adjustment during use. When the equipment is reset, each component can orderly restore its initial state. The bottom sealing plate can once again play the role of preventing dust and debris. The arc-shaped protective cover ensures the stable operation of the dual-axis motor. At the same time, the collaborative work of the main camera and the auxiliary camera mechanism allows the equipment to have multiple functions, thereby improving the stability of equipment operation, extending service life, and reducing reliance on manual monitoring. This solves the defects of existing monitoring equipment, such as single function, easy to be affected by component jamming or damage, and the need for 24-hour manual monitoring to detect obstruction problems in a timely manner.

[0017] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0018] This application discloses a multi-functional security device for smart property management. For example... Figure 1-8 As shown, the system includes a chassis 1, a main camera 2 fixedly mounted on the front of the chassis 1, an anti-obstruction module 3 fixedly mounted on the top front end of the main camera 2, a ToF sensor inside the main camera 2, a secondary camera mechanism 4 inside the chassis 1, and a transmission connection between the rear side of the anti-obstruction module 3 and the secondary camera mechanism 4. The anti-obstruction module 3 includes a front mounting slot 31, which is located at the top front of the main camera 2 housing. A dual-axis motor 32 is fixedly installed inside the front mounting slot 31. Movable frames 33 are fixedly installed on both sides of the output ends of the dual-axis motor 32. An obstruction pushing frame 34 is fixedly installed on the outside of the movable frame 33. A transmission module 35 is located on the rear side of the obstruction pushing frame 34. The transmission module 35 is connected to the secondary camera mechanism 4. During application, the housing 1 contains a controller with a timing module. The timing module can be set to delay operation when the main camera 2 is obstructed, thus avoiding immediate operation and detection by criminals. The delay can be a few seconds, allowing the anti-obstruction module 3 to be activated after the criminal has obstructed and left the camera. During application, the device utilizes the housing 1, main camera 2, anti-obstruction module 3, and ToF sensor. The sensor, secondary camera mechanism 4, transmission module 35, and controller with timing module enable intelligent monitoring and anti-obstruction linkage during use. The main camera 2 is fixed on the front of the chassis 1 and is responsible for image acquisition in the daily monitoring area. The ToF sensor is built into the main camera 2 and continuously detects whether the lens is obstructed. When an obstruction is detected, the ToF sensor transmits a signal to the controller inside the chassis 1. The timing module inside the controller starts after a preset delay to prevent the components from running immediately after obstruction and being detected by criminals. After the criminals leave, the anti-obstruction module 3 is activated. The front mounting slot 31 of the anti-obstruction module 3 is located at the front top of the main camera 2 housing. After the internal dual-axis motor 32 starts, it drives the movable frame 33 to rotate through the output ends on both sides. The movable frame 33 then drives the outer obstruction pushing frame 34 to move, clearing the obstruction at the lens of the main camera 2. At the same time, the transmission module 35 on the rear side of the obstruction pushing frame 34 transmits power to the secondary camera mechanism 4 inside the chassis 1, driving the secondary camera... Like the synchronous operation of the auxiliary camera module 4, when obstructions are not removed in time, the auxiliary camera module 4 can replace the main camera 2 to collect images, ensuring uninterrupted monitoring. It can be seen that during its use, it can not only avoid being discovered and damaged by criminals by delaying the activation of the anti-obstruction module 3, but also effectively deal with various obstruction situations through the linkage between the anti-obstruction module 3 and the auxiliary camera module 4. It solves the problems of existing monitoring equipment being easily detected by immediate action after obstruction, only being able to handle some obstructions, and being prone to monitoring interruption after obstruction. At the same time, it reduces the reliance on real-time manual monitoring, improves the practicality and reliability of the equipment in property security scenarios, and ensures the continuous monitoring effect of the community monitoring area.

[0019] Please refer to Figures 1-5A mounting frame 36 is fixedly installed on the top rear side of the obstruction pushing frame 34. A photovoltaic panel 37 is fixedly installed on the top of the mounting frame 36. The photovoltaic panel 37 is tilted. An arc-shaped protective cover 5 is fixedly installed on the top front end of the main camera 2, covering the outside of the dual-axis motor 32. During the application of this device, by setting up the mounting frame 36, the tilted photovoltaic panel 37, and the arc-shaped protective cover 5 covering the dual-axis motor 32, it can balance energy supply optimization and core component protection during use. The mounting frame 36 is fixed to the top rear side of the obstruction pushing frame 34, providing a stable installation foundation for the photovoltaic panel 37. The photovoltaic panel 37 is tilted, which can receive more sunlight at different times and efficiently convert solar energy into electrical energy to power the various operating components of the device. At the same time, the arc-shaped protective cover 5 on the top front end of the main camera 2 directly covers the outside of the dual-axis motor 32, forming a protective barrier. In actual use, the tilted... The photovoltaic panel 37 continuously converts solar energy into electrical energy to supplement the power required for the device's operation, reducing dependence on external power grids and alleviating the problems of high electricity costs and easy shutdown during power outages caused by the reliance on external power for traditional monitoring equipment. The arc-shaped protective cover 5 can effectively block external dust and rainwater, and also buffer minor external impacts, preventing the dual-axis motor 32 from being directly exposed to the complex environment and ensuring the stable operation of the dual-axis motor 32. As the power source of the anti-obstruction module 3, the stable operation of the dual-axis motor 32 ensures that the obstruction pusher 34 moves in a timely manner to efficiently remove obstructions at the lens of the main camera 2. This design not only improves energy utilization efficiency and reduces equipment operating costs and dependence on external power through the tilted setting of the photovoltaic panel 37, but also protects the dual-axis motor 32 with the arc-shaped protective cover 5, ensuring the reliable operation of the anti-obstruction module 3. In this way, the device can play a more stable and economical role in monitoring and anti-obstruction in property security scenarios.

[0020] Please refer to Figures 1-5 and Figure 8The transmission module 35 includes an arc-shaped rack 351, a fixed arm 352, a first gear 353, and a second gear 354. The fixed arm 352 is fixedly installed on the upper side of one side of the housing 1. The arc-shaped rack 351 is fixedly installed on the rear side of the obstruction pusher 34. The first gear 353 is rotatably connected to the inner side of the fixed arm 352. The second gear 354 is located on the upper side of the housing 1 near the fixed arm 352. The second gear 354 and the first gear 353 are meshed together. The first gear 353 and the arc-shaped rack 351 are meshed together. The inner side of the second gear 354 is connected to the secondary camera mechanism 4. The secondary camera mechanism 4 includes an inner movable module 41, a linkage module 42, and a secondary camera module 43. Module 41 is movable inside the upper part of the chassis 1, and linkage module 42 is movably connected to the outside of the chassis 1. Linkage module 42 and movable module are connected by transmission. Sub-camera module 43 is fixedly installed at the bottom of linkage module 42. During the application of this device, by setting up a transmission module 35 composed of arc-shaped rack 351, fixed arm 352, first gear 353 and second gear 354, and a sub-camera mechanism 4 including inner movable module 41, linkage module 42 and sub-camera module 43, stable linkage between anti-obstruction module 3 and sub-camera mechanism 4 can be achieved during use, ensuring that the monitoring function remains effective in obstruction scenarios. When anti-obstruction module 3 is activated and obstruction push frame 34 moves, the arc-shaped frame 33 on its rear side... The rack 351 moves synchronously, driving the first gear 353 meshing with it to rotate. The first gear 353 then drives the second gear 354 meshing with it. Through this power transmission, the transmission module 35 converts the movement of the anti-obstruction module 3 into power that can drive the secondary camera mechanism 4. Simultaneously, in the secondary camera mechanism 4, the inner movable module 41 moves inside the upper part of the housing 1, and the linkage module 42 is connected to the outside of the housing 1 and drives the inner movable module 41. When the second gear 354 of the transmission module 35 transmits power to the linkage module 42, the linkage module 42 drives the inner movable module 41 to move, thereby driving the secondary camera module 43 fixed at its bottom to operate. In security scenarios, this structural design allows the secondary camera module 4 to respond synchronously while the anti-obstruction module 3 removes obstructions. Through the movement of the internal movable module 41 and the transmission of the linkage module 42, the secondary camera module 43 can quickly adjust to a suitable position for image acquisition, avoiding monitoring gaps when the main camera 2 is obstructed. This solves the problem in existing technologies where the anti-obstruction component and the backup monitoring component of the monitoring equipment are difficult to work together, leading to easy monitoring interruptions after obstruction. At the same time, the transmission module 35 transmits power through the meshing of gears and racks, ensuring the stability of power transmission. The cooperation of each module of the secondary camera module 4 also makes the backup monitoring action smoother, further improving the reliability of the equipment in property security.

[0021] Please refer to Figures 5-7The internal movable module 41 includes an inner rail 411, which is fixedly installed inside the upper part of the housing 1. A movable plate 412 is slidably connected inside the inner rail 411. A ruler strip 413 is fixedly installed on the back of the movable plate 412. The ruler strip 413 is connected to the linkage module 42 for transmission. The secondary camera mechanism 4 is fixedly installed at the bottom of the movable plate 412. The linkage module 42 includes an internal gear 421, an upper synchronous pulley 422, and a lower synchronous pulley 423. The internal gear 421 is rotatably connected to the middle part of the housing 1. The internal gear 421 is meshed with the ruler strip 413. The upper synchronous pulley 422 is rotatably connected to the upper part of the housing 1. The second gear 354 is fixedly installed on the side of the upper synchronous pulley 422 away from the housing 1. The lower synchronous pulley 423 is rotatably connected to the lower end of the housing 1 near the fixed arm 352. The upper synchronous pulley 422 and the lower synchronous pulley 423 are connected by a synchronous belt 424. The inner side of the lower synchronous pulley 423 is fixedly connected to one side of the internal gear 421 by a coupling. During the application of this device, its ingenious structure of the inner movable module 41 and the linkage module 42 working together allows the secondary camera mechanism 4 to exhibit excellent flexibility and stability during operation. When the anti-obstruction module 3 is activated, it drives the transmission module 35 to rotate, thereby activating... When the linkage module 42 is activated, the internal gear 421 begins to rotate. Because the internal gear 421 meshes tightly with the ruler strip 413, the ruler strip 413 moves in a specific direction along with the rotation of the internal gear 421. The movable plate 412, fixed on the ruler strip 413, also slides smoothly within the inner rail 411. Simultaneously, the upper synchronous pulley 422, lower synchronous pulley 423, and synchronous belt 424 in the linkage module 42 work together to efficiently transmit power, ensuring the stable and continuous rotation of the internal gear 421. During the sliding of the movable plate 412, the auxiliary camera mechanism 4 installed at its bottom also moves accordingly, quickly adjusting to... If a suitable position is required and the main camera 2 needs to be further aligned with a key area, the secondary camera 4 can also adjust its angle. This close cooperation allows the secondary camera 4 to respond quickly and take over the monitoring responsibility when the main camera 2 is blocked, avoiding gaps in monitoring. During the device reset phase, each component can return to its initial state in an orderly manner according to the opposite transmission logic, ensuring that the device can respond to the next blockage at any time. This design effectively solves the problem that the backup camera components of traditional monitoring equipment are difficult to respond quickly and flexibly adjust their position and angle, greatly improving the practicality and reliability of the equipment in security scenarios.

[0022] Please refer to Figures 6-7The secondary camera module 43 includes a horizontal plate 431, which is fixedly installed at the bottom of the movable plate 412. A hinge frame 432 is fixedly installed on one side of the bottom of the horizontal plate 431. An adjusting wheel 433 is rotatably connected inside the hinge frame 432. A drive motor 434 is fixedly installed on one side of the hinge frame 432. The output end of the drive motor 434 passes through the hinge frame 432 and is fixedly connected to one side of the adjusting wheel 433. A base frame 435 is fixedly installed at the bottom of the adjusting wheel 433. A secondary camera 436 is fixedly installed inside the base frame 435. Connecting legs 44 are fixedly installed at the four corners of the bottom of the horizontal plate 431. Bottom seals are fixedly installed at the bottom of the connecting legs 44. A blocking plate 45 covers the bottom of the chassis 1. A fixing post 6 is fixedly installed in the middle of the back of the chassis 1. A mounting plate 8 is fixedly installed on the back of the fixing post 6. Mounting holes 7 are provided at the four corners of the mounting plate 8. The mounting holes 7 are countersunk holes. During the application of this device, by setting up a secondary camera module 43 consisting of a horizontal plate 431, a hinge frame 432, an adjusting wheel 433, a drive motor 434, a base frame 435, and a secondary camera 436, as well as connecting legs 44, a bottom blocking plate 45, and mounting plates 8 and fixing posts 6 with countersunk holes 7, it is possible to achieve both flexible adjustment and stable protection of the secondary camera 436 during use. To ensure secure installation, during installation, the mounting bracket 6 connects the chassis 1 to the mounting plate 8. Bolts are used to fix the equipment in the designated position through the countersunk holes at the four corners of the mounting plate 8. The countersunk holes allow the bolt heads to be embedded, preventing exposure that could affect installation stability or cause accidental loosening. In daily use, the horizontal plate 431 provides the mounting base for the various components of the secondary camera module 43. When the angle of the secondary camera 436 needs to be adjusted, the drive motor 434 starts, and its output drives the adjusting wheel 433 inside the hinge frame 432 to rotate. The adjusting wheel 433 drives the secondary camera 436 to rotate synchronously through the base frame 435, thereby accurately aligning it with the monitoring target area. Simultaneously, the bottom of the horizontal plate 431... The connecting legs 44 at the four corners of the unit support the bottom sealing plate 45, which covers the bottom of the chassis 1. This prevents dust and debris from entering the chassis 1 and protects the components inside the chassis 1 so that they can operate normally. This design allows the secondary camera 436 to not only flexibly adjust its angle to ensure monitoring coverage, but also reduces the impact of the external environment on the internal components of the equipment through the bottom sealing plate 45. In addition, the stable installation structure solves the problems of inconvenient angle adjustment of the secondary camera 436 in existing monitoring equipment, easy interference from debris inside the equipment, and easy loosening after installation. This further improves the applicability and durability of the equipment in property security scenarios and ensures stable and continuous monitoring.

[0023] The implementation principle of a multi-functional security device for smart property management according to this application embodiment is as follows: During application, staff first use bolts to fix the entire device at locations requiring monitoring, such as community entrances / exits and main roads, through the countersunk holes at the four corners of the mounting plate 8. The mounting plate 8 is stably connected to the center of the back of the chassis 1 via fixing posts 6, ensuring that the device will not easily shake due to external forces after installation. After the device is powered on, the controller inside the chassis 1 immediately enters the working state. Staff can preset the delay time of the timing module through the controller, which can be flexibly adjusted according to the security needs of the community. The main camera 2 starts simultaneously to collect real-time images of the target area. The photovoltaic panel 37 is fixed to the top rear side of the obstruction pusher 34 via the mounting bracket 36, and the whole is set at an angle. This setting allows the photovoltaic panel 37 to receive solar energy more efficiently under sunlight conditions, converting it into electrical energy to power the controller, main camera 2, and ToF. The sensors and other components are powered, thereby reducing the equipment's dependence on external power and reducing the electricity costs of property management. At this time, the secondary camera mechanism 4 is in its initial state, with the movable plate 412 located on the inner rail 411 near the inside of the chassis 1. The inner rail 411 is fixed to the upper part of the chassis 1, providing a stable sliding track for the movable plate 412. The secondary camera 436 is hidden inside the chassis 1, and the bottom sealing plate 45 is fixed to the four corners of the bottom of the horizontal plate 431 by connecting legs 44 and covers the bottom of the chassis 1. This structure allows the bottom sealing plate 45 to effectively prevent... Dust and debris entering the interior of the chassis 1 prevent the internal moving module 41, linkage module 42 and other components from jamming or being damaged due to foreign object interference, thus extending the service life of the equipment and improving the operational stability of the equipment. The arc-shaped protective cover 5 at the top front of the main camera 2 covers the outside of the dual-axis motor 32. The dual-axis motor 32 is fixed inside the front mounting slot 31, which is located at the top front of the main camera 2 housing. The arc-shaped protective cover 5 can protect the dual-axis motor 32 from dust, rain and slight external forces in the external environment, ensuring the stable operation of the dual-axis motor 32. The ToF sensor inside the main camera 2 continuously monitors the environment in front of the lens. When it detects objects such as cloth, plastic sheeting, chewing gum, or transparent tape approaching and blocking the lens of the main camera 2, the ToF sensor immediately transmits the blocking signal to the controller inside the chassis 1. After receiving the signal, the controller quickly starts the internal timing module and begins timing according to the preset delay time. During the timing process, the device maintains its current state and does not immediately start the anti-blocking module 3 and the secondary camera mechanism 4. This design can prevent the main camera 2 from immediately running related components once it is blocked, which would be noticed by criminals. After blocking the main camera 2, criminals usually think that the monitoring has failed and leave quickly. This device, through the delay effect of the timing module, reserves time for criminals to leave the scene, ensuring that subsequent anti-blocking actions and secondary camera image acquisition can be carried out after the criminals have left, thereby reducing the probability that criminals will find that the device is still working and further damage the device, and improving the practicality of the device in actual security scenarios. After the timing module completes the preset delay time, the controller sends a start signal to the dual-axis motor 32 of the anti-obstruction module 3. Upon receiving the signal, the dual-axis motor 32 starts immediately, and its two output ends drive the movable frame 33 to rotate. The movable frame 33 then drives the obstruction pushing frame 34 to move synchronously. The obstruction pushing frame 34 acts directly on the obstruction at the lens of the main camera 2 by rotating or moving. For larger obstructions such as cloth and plastic sheeting, it can push them away from the lens. For smaller sticky obstructions such as chewing gum and transparent tape, if the pushing action cannot remove them from the lens for cleaning, the device will rely on the secondary camera module 43 to maintain the monitoring function. During this process, the arc-shaped rack 351 on the rear side of the obstruction pushing frame 34 moves with the obstruction. The moving frame 34 moves synchronously, and the arc-shaped rack 351 meshes with the first gear 353 fixed inside the fixed arm 352. The fixed arm 352 is fixed to the upper side of the chassis 1, providing stable rotational support for the first gear 353. The movement of the arc-shaped rack 351 drives the first gear 353 to rotate. The first gear 353 then meshes with the second gear 354 located on the upper side of the chassis 1 near the fixed arm 352, thereby driving the second gear 354 to rotate and starting the power transmission process of the transmission module 35. The second gear 354 is fixedly installed on the side of the upper synchronous pulley 422 away from the chassis 1. The rotation of the second gear 354 drives the upper synchronous pulley 422 to rotate synchronously. The upper synchronous pulley 422 is connected to the lower synchronous pulley 423 through the synchronous belt 424. Next, the lower synchronous pulley 423 is rotatably connected to the lower end of the side of the housing 1 near the fixed arm 352. The rotation of the upper synchronous pulley 422 drives the lower synchronous pulley 423 to rotate through the synchronous belt 424. The inner side of the lower synchronous pulley 423 is fixedly connected to one side of the internal gear 421 through a coupling. The internal gear 421 is rotatably connected to the middle of the housing 1. The rotation of the lower synchronous pulley 423 drives the internal gear 421 to rotate. The internal gear 421 meshes with the ruler strip 413 fixed on the back of the movable plate 412. When the internal gear 421 rotates, it drives the ruler strip 413 to move horizontally. The ruler strip 413 drives the movable plate 412 to slide along the inner rail 411 to the outside of the housing 1. At the same time as the movable plate 412 slides, it drives the bottom fixed horizontal plate 431 and the auxiliary camera module 43 to move synchronously towards the housing. As the outer side moves, the bottom sealing plate 45 gradually detaches from the bottom of the chassis 1 along with the horizontal plate 431, no longer blocking the bottom opening of the chassis 1, providing ample space for the secondary camera 436 to protrude from the chassis 1. When the secondary camera module 43 moves to a suitable position outside the chassis 1, the controller sends a signal to the drive motor 434 of the secondary camera module 43. The drive motor 434 is fixed to one side of the hinge frame 432, and its output end passes through the hinge frame 432 and is fixedly connected to one side of the adjusting wheel 433. After the drive motor 434 starts, it drives the adjusting wheel 433 to rotate inside the hinge frame 432. The base frame 435 fixed at the bottom of the adjusting wheel 433 rotates with the adjusting wheel 433, and the secondary camera 436 fixed inside the base frame 435 also adjusts its angle accordingly. This is achieved by the forward and reverse rotation of the drive motor 434.The secondary camera 436 can be adjusted at multiple angles within a certain range, ensuring that it can be aimed at the area originally monitored by the main camera 2, or, depending on actual needs, at key areas such as the direction of the obstruction's origin for real-time image acquisition. This compensates for the temporary inability of the main camera 2 to function due to obstruction. Regardless of whether the obstruction at the main camera 2 is successfully removed, the secondary camera 436 can provide backup monitoring through angle adjustment and position movement, preventing monitoring failure due to the main camera 2 being obstructed, and ensuring the continuity and comprehensiveness of monitoring. Simultaneously, the photovoltaic panel 37 fixed on the mounting bracket 36 at the top rear of the obstruction pusher 34 continuously supplies power to the equipment throughout the process, ensuring stable operation of all components and further reducing the equipment's dependence on external power. When the ToF sensor inside the main camera 2 detects that the obstruction at the lens has been completely removed and the main camera 2 resumes normal image acquisition, the ToF sensor will transmit a recovery signal to the controller. After receiving the signal, the controller sends a reverse start signal to the dual-axis motor 32. The dual-axis motor 32 starts in reverse, driving the movable frame 33 and the obstruction pushing frame 34 to reset. The arc-shaped rack 351, along with the obstruction pushing frame 34, drives the first gear 353 and the second gear 354 to rotate in reverse. The reverse power is transmitted through the transmission module 35, causing the internal gear 421 to rotate in reverse, thereby driving the ruler strip 413 and the movable plate 412 to slide along the inner rail 411 towards the inside of the chassis 1. The secondary camera module 43, along with the movable plate 412, resets into the inside of the chassis 1. The bottom sealing plate 45 covers the bottom of the chassis 1 again, once again serving the function of preventing dust and debris. At the same time, the controller sends a reverse start signal to the drive. The drive motor 434 sends a reverse start signal, which drives the adjustment wheel 433 and the secondary camera 436 to reset. The secondary camera mechanism 4 returns to its initial state and waits for the next linkage action to be triggered. During this process, the main camera 2 continuously collects images, and the controller receives the operation signals of each component in real time to ensure that all parts of the equipment work in coordination. This technical solution, through the cooperation of the main camera 2 and the secondary camera mechanism 4, combined with the intelligent control of the controller and the timing module, enables the equipment to have multiple functions such as basic monitoring, obstruction detection, delayed start, obstruction removal, and backup monitoring. It breaks the limitation of traditional property security monitoring equipment that can only realize basic shooting and monitoring functions, greatly reduces the equipment's dependence on 24-hour real-time monitoring by security personnel, avoids the situation where criminals escape monitoring due to human negligence, and comprehensively improves the effectiveness of the community security system. During the application of this device, the main camera 2 can be a Hikvision DS-2CD3T46FWDA4-LS, a 4MP intelligent surveillance camera that uses deep learning hardware and algorithms and supports functions such as occlusion alarm. When the camera is obstructed, an alarm can be triggered. The linkage methods include uploading to FTP / SD card / NAS, recording, capturing images, alarm output, and sound alarm. Alternatively, a Hikvision DS-2CD3526FWDA3-ITS / DT can be used, which has a built-in ToF sensor that can effectively detect camera obstruction. The maximum detection angle is 25°, and the default detection distance is 70cm. When obstruction is detected, an alarm will be triggered. Finally, a TP-LINK TL-NAIPC5884P-B6, an 8MP low-light full-color AI intelligent network camera, can be used. It supports video occlusion detection. When this function is enabled, the camera will automatically alarm when it is obstructed.

Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
