Description

Technical Field

[0001] This utility model relates to the field of monitoring technology, and more specifically, to a building security monitoring device. Background Technology

[0002] With the acceleration of urbanization and the proliferation of high-rise buildings, building security has become increasingly important. Security monitoring systems, as a core technological means to ensure the safety of people and property within buildings, are widely used in various types of buildings, including residential buildings, office buildings, shopping malls, and hotels. Among these, video surveillance equipment (cameras) are the "eyes" of the entire system, and their performance and deployment methods directly determine the effectiveness and reliability of the security system.

[0003] Traditional building security monitoring solutions commonly employ fixed-location camera installation. This involves installing multiple cameras with fixed viewing angles in key areas requiring monitoring, such as lobbies, corridors, entrances, and stairwells. Each camera covers a specific static area, and the combined footage from multiple cameras achieves seamless monitoring of the entire building's public areas. However, this traditional static deployment method has gradually revealed its limitations in practice: First, surveillance systems have blind spots and dead zones. Because cameras are fixed in place, their field of view is limited by the lens focal length and installation location. In areas with complex spatial structures, pillars, corners, or large obstructions, blind spots are easily created. Malicious individuals can exploit these blind spots to evade surveillance and carry out illegal activities, posing a significant threat to security. The usual solution to eliminate blind spots is to increase the number of cameras, but this directly leads to increased costs.

[0004] Second, equipment utilization and monitoring efficiency are low. For the vast majority of the time, many areas within the building are either secure or inactive. Fixed cameras continuously record empty footage of these areas, resulting in a huge waste of storage space and network bandwidth. This also increases the burden on back-end personnel for monitoring and screening, making them prone to overlooking real threats due to fatigue.

[0005] Third, the initial deployment and subsequent maintenance costs are high. To achieve comprehensive coverage, a large number of camera locations, cabling (power lines and network cables), and supporting equipment such as switches need to be planned during the design and construction phases. This not only increases procurement costs but also significantly increases the complexity and workload of installation and cable laying. In addition, when the monitoring angle in a certain area needs to be adjusted, manual on-site adjustments or even reinstallation are required, resulting in high maintenance costs.

[0006] To overcome some of the shortcomings of fixed cameras, PTZ cameras were developed. These cameras have horizontal rotation, vertical tilt, and zoom functions, and can be cruised through preset positions or manually controlled by the operator, thereby expanding the monitoring range of a single device. However, PTZ cameras still have their limitations: First, their rotating base is usually fixed at a single point, and although their field of view is larger than that of fixed cameras, it is still a cone-shaped area with the mounting point as the apex, which cannot achieve large-scale linear movement and is still insufficient for narrow terrains such as long corridors; second, the complex mechanical structure makes their manufacturing and maintenance costs much higher than those of fixed cameras; third, they cannot monitor other areas when in motion, which may cause them to miss critical events.

[0007] Therefore, there is an urgent need in this field for a new type of building security monitoring equipment that can effectively solve many of the problems in the existing technologies mentioned above. An ideal new device should be able to achieve smooth, efficient, and blind-spot-free coverage of a large area with a single device, while maintaining low cost and low power consumption. It should also possess stable mobility, accurate positioning capabilities, and flexible viewing angle adjustment functions, thereby significantly reducing costs and maintenance complexity while improving monitoring efficiency and effectiveness.

[0008] For example, Chinese utility model patent CN222669508U discloses a building security monitoring device, including a fixing plate and a monitoring camera body. The fixing plate has a rectangular frame at its bottom, and a lifting mechanism for height adjustment is provided on the rectangular frame. A connecting plate is provided on the top of the monitoring camera body. The lifting mechanism has an installation mechanism for clamping and fixing the connecting plate, and the installation mechanism is located on the connecting plate. The lifting mechanism includes two T-shaped columns, which are rotatably mounted on the rectangular frame. Two connecting wheels are installed on the outer walls of each of the two T-shaped columns, and steel cables are provided on all four connecting wheels. A rectangular plate is provided at the bottom of each of the four steel cables, thus facilitating the installation and removal of the monitoring camera body and allowing for height adjustment. While this utility model achieves a certain degree of camera height adjustment and switching between camera directions, its monitoring coverage is no different from traditional security monitoring equipment. Furthermore, the adjustment range is limited, requiring manual adjustment by workers climbing to a height. The structure is not stable, and its flexibility is very limited, failing to save manpower and resources. Utility Model Content

[0028] This utility model proposes a building security monitoring device.

[0029] The building security monitoring equipment of this application will be described in detail below through the following embodiments.

[0030] Example 1: like Figure 1 , 2As shown, this embodiment proposes a building security monitoring device, including: a track 1; and a camera device 2, which is mounted on the track 1 and can move along the track 1. The camera device 2 includes: a base 21, the bottom surface of which is disposed on a buckle 212, the base 21 is mounted on the track 1 via the buckle 212 and can slide along the track 1; a camera 22, which is mounted on the base 21 and can rotate in the vertical direction; a track drive mechanism 23, which is disposed between the base 21 and the track 1 and drives the base 21 to move along the track 1; and a camera drive mechanism 24, which is disposed between the camera 22 and the base 21 and drives the camera 22 to rotate on the base 21.

[0031] The camera device 2 is moved along the track 1 by the cooperation between the track drive mechanism 23 mounted on the base 21 and the track 1. The latch 212 secures the camera device 2 to the track 1, preventing it from shaking or falling off. This allows for flexible switching of the camera 22's position, providing a large range and degree of freedom for adjusting its field of view. The camera drive mechanism 24 mounted on the base 21 rotates the camera 22 on the base 21, allowing for changes in the camera 22's vertical viewing angle. The track 1 can be flexibly installed on walls, ceilings, etc., enabling highly customizable monitoring system field of view and angle.

[0032] Example 2: This embodiment is a further improvement based on Embodiment 1.

[0033] like Figure 2 As shown, in this embodiment, a drive groove 11 is provided on the side of the track 1 near the camera 22, and a track rack 111 is provided on one side of the drive groove 11; the track drive mechanism 23 includes a track drive motor 231 and a track drive gear 232. The track drive motor 231 is fixed to the bottom of the base 21, and the track drive gear 232 is fixed to the output shaft of the track drive motor 231. The track drive gear 232 extends into the drive groove 11 and meshes with the track rack 111.

[0034] When the control system issues a movement command, motor 231 receives the electrical signal and begins to rotate. The output power of motor 231 is transmitted to the track drive gear 232, which is fixedly mounted on the output shaft of motor 231. When gear 232 rotates, its rotation center is displaced due to the fixed rack 111, causing it to move linearly along the length of rack 111. The direction of movement of camera device 2 can be changed by controlling the rotation direction of motor 231. The movement speed of camera device 2 can be adjusted by controlling the rotation speed of motor 231, enabling a smooth switch between slow patrols and rapid responses to different scenarios.

[0035] Example 3: This embodiment is a further improvement based on any of the above embodiments.

[0036] like Figure 3 As shown, in this embodiment, a connecting bracket 211 is provided on the upper end of the base 21, and connecting rods 221 are provided on both sides of the camera 22, which are rotatably connected to the connecting bracket 211. The camera driving mechanism 24 includes: a camera driving motor 241, fixed to the outer surface of the base 21; and a gear set 242, including: a first gear 2421, a second gear 2422, a worm gear 2423, and a worm 2424. The first gear 2421 is fixed on the output shaft of the camera driving motor 241. The second gear 2422 meshes with the first gear 2421. One end of the worm 2424 is connected to the second gear 2422, so that the second gear 2422 and the worm 2424 rotate synchronously. The worm 2424 meshes with the worm gear 2423, and the worm gear 2423 is fixed to the end of the connecting rod 221 near the camera driving motor 241. The second gear 2422 has more teeth than the first gear 2421.

[0037] When the control system needs to adjust the pitch angle of the camera 22, it sends a command to the motor 241, causing its output shaft to rotate. A small first gear 2421 fixed to the output shaft of the motor 241 meshes with a larger second gear 2422, forming the first stage of transmission. This reduces the rotational speed and increases the output torque, converting the high speed and low torque of the motor 241 into a lower speed and higher torque output, providing a more easily controllable power foundation for subsequent transmissions. The reduced power is transmitted to the worm gear 2424, which is coaxially fixed to the second gear 2422. The rotation of the second gear 2422 drives the worm gear 2424 to rotate synchronously. The rotation of the worm gear 2424 drives the worm wheel 2423 to rotate. The worm wheel 2423 is fixedly mounted on the camera 22's rotating shaft (i.e., connecting rod 221). Therefore, the rotation of the worm wheel 2423 directly translates into the pitch oscillation of the camera 22. Among them, the worm gear 2423 and worm 2424 structure change the direction of rotation transmission, reduce the volume of the transmission part, and provide unidirectional transmission to prevent the camera 22 from shaking after adjusting the pitch angle, thus ensuring the stability of the image.

[0038] Example 4: This embodiment is a further improvement based on any of the above embodiments.

[0039] like Figure 1 As shown, in this embodiment, there are four camera devices 2, which are arranged sequentially on the track 1. This allows for simultaneous monitoring from four directions.

[0040] Example 5: This embodiment is a further improvement based on any of the above embodiments. like Figure 1 As shown, in this embodiment, track 1 is a ring. Camera 22 can move along the circumference of track 1 to achieve 360-degree switching monitoring of a certain area.

[0041] Example 6: This embodiment is a further improvement based on any of the above embodiments.

[0042] like Figure 4 In this embodiment, roller grooves 12 are provided on both sides of the track 1, and rollers 213 are provided on the buckle 212. The rollers 213 cooperate with the roller grooves 12 to change the movement of the base 21 on the track 1 from sliding friction to rolling friction, which reduces resistance, extends the service life of the device, and reduces noise.

[0043] The various embodiments of this disclosure have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
