[0027] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.

[0028] Reference Figure 1-4 The black light camera technology solution provided by this utility model mainly utilizes a bracket body 100, a first motor 120, a ball head bracket 200, a camera assembly 300, a second motor 340, a waterproof lens 311, and a black light lens 351. Through the coordinated operation of these components, black light night vision and panoramic monitoring functions are achieved. This invention uses the first motor 120 and the second motor 340 to drive the camera to rotate omnidirectionally, while simultaneously combining black light imaging to solve the imaging problem of traditional surveillance in low-light environments.

[0029] The main support body 100 serves as the load-bearing structure for the entire device. A base 110 on one side provides the mounting interface, allowing the camera to be securely fixed in various installation positions. The first motor 120 is located inside the main support body 100 and its output end is fixedly connected to the top of the ball head bracket 200, enabling horizontal rotation of the camera. This solves the problem of reduced protection performance caused by exposed transmission mechanisms common in traditional pan-tilt units. The ball head bracket 200 employs a double-arm structure 210, providing a support platform for the camera assembly 300 while ensuring mechanical strength and motion accuracy during rotation.

[0030] Reference Figure 2 , 4 The front shell 310 and rear shell 320 of the camera assembly 300 are assembled to form a sealed receiving cavity 330, which provides a good protective environment for the internal optical and electronic components. At least one second motor 340 is installed in the receiving cavity 330 at a position corresponding to the support arm 210. By driving the camera assembly 300 to rotate vertically relative to the support arm 210, it cooperates with the horizontal rotation of the first motor 120 to form a dual-axis gimbal system, enabling the camera to achieve flexible attitude adjustment in three-dimensional space.

[0031] Furthermore, the receiving cavity 330 is also equipped with a TF card slot. For storage expansion, the TF card slot is sealed with a waterproof plug. When it is not necessary to replace the memory card, the waterproof plug can completely seal the slot. When it is necessary to insert or remove the TF card, the waterproof plug can be easily removed and reinstalled.

[0032] Furthermore, a waterproof gasket 112 is provided between the front shell 310 and the rear shell 320.

[0033] As a front-end protective component, the waterproof goggle 311 needs to ensure optical transmittance and fulfill the important functions of waterproofing and dustproofing. The black light lens 351 is mounted behind the waterproof goggle 311 and uses a combination of large aperture and high-sensitivity optical lenses. Together with a back-illuminated image sensor, it can capture sufficient light information in extremely low-light environments to achieve clear imaging results.

[0034] In some embodiments, the first motor 120 transmits power to the ball joint bracket 200, enabling it to rotate horizontally, while the second motor 340 drives the camera assembly 300 to rotate 90 degrees vertically. This dual-axis independent drive allows the camera to respond quickly to control commands, achieving precise positioning and smooth tracking.

[0035] Specifically, both the first motor 120 and the second motor 340 are stepper motors. Stepper motors have excellent holding torque characteristics when stationary, and can maintain their current position even when power is off. This is especially important for surveillance applications where a fixed monitoring angle needs to be maintained for a long time, ensuring that the camera can maintain its original monitoring view when power is restored after an unexpected power outage, without the need for repositioning.

[0036] When a specific area needs to be monitored, the control system calculates the corresponding horizontal and vertical rotation angles based on the target position, and then drives two motors to perform the corresponding rotation actions, thereby accurately pointing the lens at the target position.

[0037] In some embodiments, refer to Figure 2 , 3 4. The bracket body 100 has an internal mounting cavity 130. The top end of the ball head bracket 200 extends into the mounting cavity 130 and can rotate freely within it. A first stop 131 on the inner wall of the mounting cavity 130 and a second stop 221 in the concave cavity 220 at the top of the ball head bracket 200 form a mechanical limiting engagement. When the ball head bracket 200 rotates to a preset limit position, the contact between the two stops effectively limits its continued rotation, avoiding cable entanglement or mechanical damage that may result from excessive rotation. This limiting setting ensures that the camera maintains stable mechanical performance during long-term continuous operation.

[0038] It should be noted that due to the presence of the first stop 131 and the second stop 221, the horizontal rotation range of the ball joint bracket 200 driven by the first motor 120 is limited to 336 degrees, rather than a complete 360-degree rotation. Specifically, the first stop 131 and the second stop 221 effectively prevent excessive tangling of the connecting cables while ensuring a wide range of camera rotation. When the ball joint bracket 200 rotates to its horizontal limit of 336 degrees, the first stop 131 located on the inner wall of the mounting cavity 130 will contact the second stop 221 in the concave cavity 220 at the top of the ball joint bracket 200. The resistance generated by the mechanical contact prevents further rotation, thereby protecting the internal power supply line 140, signal line, and data transmission cable from tangling or breaking due to excessive rotation. Furthermore, the 336-degree rotation range is sufficient to cover the needs of most monitoring scenarios, and in practical applications, it is almost equivalent to a panoramic monitoring effect.

[0039] In some embodiments, refer to Figure 2 , 4 The main body 100 of the bracket houses a power supply 140. A charging port 111 is located on the base 110 to charge the power supply 140. The charging terminal inside the charging port 111 is electrically connected to the power supply 140. When the device needs charging, simply insert the charger into the charging port 111 to transfer power. The charging port 111 has a recessed structure, and together with a removable waterproof pad 112, it effectively seals the charging port 111 when not charging, preventing rain or dust from entering. When charging is needed, the waterproof pad 112 can be easily removed for charging.

[0040] In some embodiments, refer to Figure 3 , 4 The wall mount bracket 400 has a snap-fit ​​cavity 410 that forms a matching installation interface with the first snap-fit ​​part 113 on the base 110. When the base 110 is inserted into the snap-fit ​​cavity 410, the first snap-fit ​​part 113 engages with the corresponding second snap-fit ​​part 411 on the inner wall of the snap-fit ​​cavity 410. This structure facilitates the secure fixing of the base 110 to the wall mount bracket 400 and allows for easy disassembly when the installation angle needs to be adjusted or equipment maintenance is required. The snap-fit ​​cavity 410 of the wall mount bracket 400 has a bottom 412 and at least one side 413. The first fixing surface formed by the bottom 412 and the second fixing surface formed by the side 413 are adapted to different installation surfaces, and the fixing parts 414 provided on these fixing surfaces fix the entire bracket to the wall surface by bolts or other fasteners, thereby realizing various installation methods such as pole mounting, ceiling mounting, and wall mounting.

[0041] The first snap-fit ​​part 113 and the second snap-fit ​​part 411 can adopt a variety of specific mechanical connection structures to achieve quick installation and firm fixation.

[0042] In one embodiment, the first latching part 113 may be provided with a plurality of radially protruding latches on the outer periphery of the base 110, while the second latching part 411 is a slot or groove structure located on the inner wall of the latching cavity 410. When the base 110 is inserted into the latching cavity 410, the latch claws can cooperate with the slot and achieve locking through elastic deformation.

[0043] In another embodiment, the first snap-fit ​​part 113 can adopt a spiral snap-fit ​​structure, that is, a spiral protruding track is provided on the outer surface of the base 110, while the second snap-fit ​​part 411 is provided with a corresponding spiral groove on the inner wall of the snap-fit ​​cavity 410, and the two are tightly fitted by rotating insertion.

[0044] Furthermore, the first locking part 113 can also be an elastic retaining ring structure, with a radially retractable elastic ring provided at a specific position on the base 110, while the second locking part 411 has an annular locking groove within the locking cavity 410. When the base 110 is fully inserted, the elastic retaining ring automatically springs back and embeds into the locking groove to form a reliable mechanical lock. Both of these structures can provide sufficient connection strength while ensuring ease of installation, meeting the stability requirements of the camera in various installation environments.

[0045] In some embodiments, two second motors 340 can be provided, respectively positioned within the receiving cavity 330 corresponding to the positions of the two support arms 210. The dual motors not only provide greater driving torque but also enable more precise attitude adjustment through differential control. When the camera needs to rotate rapidly at a large angle, the two motors can work synchronously to provide maximum driving force, while when fine-tuning or precise positioning is required, high-precision position adjustment can be achieved through the control of a single motor.

[0046] In some embodiments, refer to Figure 4 The camera assembly 300 also includes a motherboard 350, a light board 360, and a black light lens 351, which work together to achieve excellent low-light imaging performance.

[0047] The motherboard 350 serves as the core carrier, not only housing key electronic components such as the image processing chip and memory, but also providing an installation reference for the black light lens 351. Multiple infrared dual-core lamps 361 are arranged on the lamp board 360, which is electrically connected to the motherboard 350. These infrared dual-core lamps 361 employ an emission wavelength of 800-940nm, a wavelength range that not only provides sufficient supplementary lighting but also avoids visible light interference to the human eye.

[0048] In some embodiments, refer to Figure 4Multiple infrared dual-core LEDs 361 are evenly distributed around the black light lens 351 on the light panel 360. This ring arrangement ensures uniform illumination and avoids the shadows or uneven lighting problems that may occur with traditional single-point light sources. When the camera operates in extremely low light environments, the infrared dual-core LEDs 361 automatically adjust their luminous power according to the ambient light intensity. Combined with the large aperture and high-sensitivity sensor of the black light lens 351, the entire system can still output vivid and detailed images in extremely dark environments of 0.001 Lux, solving the problems of colorlessness and low detail in traditional infrared night vision devices.

[0049] In some embodiments, refer to Figure 1 , 2 4. The device also integrates a 4G antenna 150 to enable remote monitoring and data transmission functions.

[0050] Specifically, the 4G antenna 150 adopts a dual-antenna configuration, with two 4G antennas 150 respectively positioned at the top of both sides of the main support body 100, establishing a signal connection with the internal 4G communication module via an SMA interface. The external dual antennas not only enhance signal reception gain in both horizontal and vertical directions but also improve signal reception reliability through spatial diversity, reducing the communication interruption rate in weak signal environments by more than 90% compared to a single-antenna solution. When the camera is deployed in remote mountainous areas, construction sites, or other outdoor scenarios lacking wired network coverage, the dual antennas can effectively capture and process 4G signals from different directions, ensuring a stable network connection even in complex environments with weak signal strength or obstructions, thereby guaranteeing real-time transmission of remote monitoring images and timely response to control commands.

[0051] The antenna placement must avoid interference with rotating components while ensuring good signal reception under various rotational orientations. When the camera is installed in remote areas or locations lacking wired network access, the 4G communication module can establish a stable data transmission link, allowing users to view monitoring footage in real time, remotely control camera rotation, and receive alarm information via mobile network, thus greatly expanding the application range and flexibility of the equipment.

[0052] In some embodiments, a radio component and a speaker component are also included to enable voice intercom functionality.

[0053] The audio receiving unit, through the integration of a high-sensitivity microphone module, can effectively capture ambient sound and human voice information within the monitored area. This microphone module is typically mounted on the front housing 310 of the camera unit 300 and is equipped with a corresponding waterproof and acoustically permeable membrane to ensure normal operation even in adverse weather conditions.

[0054] The speaker assembly is responsible for converting the remotely transmitted voice signal into audible sound output on-site. The speaker unit also needs to have good waterproof performance, typically employing a waterproof speaker design and a specialized acoustic diaphragm. When monitoring personnel need to communicate with on-site personnel in real time, the voice signal from the remote control terminal is transmitted via a 4G network to the camera's speaker assembly for playback, while the on-site sound is collected by the audio receiver and transmitted back to the remote control terminal in real time, thus establishing a two-way voice communication link. This system can not only be used for remote warnings and deterrence but also provide timely guidance and assistance to on-site personnel in emergencies, greatly enhancing the interactivity and practicality of the monitoring system.

[0055] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
