Description

Technical Field

[0001] This utility model relates to the field of surveillance camera technology, and more specifically, to a PTZ surveillance camera. Background Technology

[0002] As a crucial piece of equipment in the security field, PTZ cameras enable wide-area, multi-angle monitoring coverage due to their dynamic rotation capabilities. However, in nighttime or low-light environments, cameras require supplemental lighting to ensure image clarity. Currently, most PTZ cameras employ supplemental lighting solutions with significant limitations: fixed-angle supplemental lights are incompatible with the dynamic adjustment capabilities of the camera's pan / tilt unit. When the camera rotates horizontally (typically covering a range of 0°-355°) or tilts vertically (commonly -15° to 90°), the illumination range of the fixed light source cannot keep up with the lens's angle of view, causing a deviation between the supplemental lighting area and the monitoring field of view. This "dynamic-static" contradiction creates significant blind spots, potentially causing 30%-50% illuminance at extreme angles, severely impacting video image quality. Summary of the Invention

[0003] This utility model aims to solve one of the technical problems in related technologies to a certain extent. To this end, this utility model proposes a PTZ camera, in which the supplementary light is linked to the PTZ camera body through a connector, so as to realize the synchronous adjustment of the illumination direction with the rotation of the Z-axis, effectively eliminating the supplementary lighting blind spot and improving the imaging clarity and coverage uniformity at night and in low light conditions.

[0004] The technical solution adopted by this utility model is: to provide a PTZ camera, comprising:

[0005] The fixed frame has a drive unit inside its cover;

[0006] The PTZ camera body is rotatably mounted on the fixed frame, and the drive unit is used to drive the PTZ camera body to rotate relative to the fixed frame about the Z-axis.

[0007] A supplementary light is mounted on the mounting bracket;

[0008] A connector connects the drive unit to the fill light, enabling the fill light to rotate synchronously with the PTZ camera body.

[0009] With the above structure, the supplementary light is no longer a static, fixed illumination source. Instead, it is linked to the PTZ camera body via a connector, allowing it to adjust its illumination direction synchronously as the PTZ camera body rotates around the Z-axis. This ensures that the illumination range of the supplementary light remains consistent with the lens's shooting direction when the camera pans horizontally or vertically, significantly reducing blind spots and illuminance attenuation caused by angular shifts.

[0010] Specifically, when the PTZ camera rotates to any angle, the supplementary lights adjust their angle synchronously under the drive of the connectors, achieving dynamic real-time supplementary lighting. This "dynamic-dynamic synchronization" method effectively improves imaging quality at night and in low-light environments, ensuring that the monitoring screen still has uniform and sufficient lighting effects when it has full coverage.

[0011] According to one embodiment of this utility model, the connector is provided with a vertical positioning plate. When the connector drives the fill light to rotate, the positioning plate always remains in contact with the arc-shaped sidewall of the cover. Preferably, the fill light is a large-area LED panel light (commonly known as a light panel). To improve its stability during rotation and reduce vibration, a positioning plate is added to the structure. Since the connector is directly or indirectly connected to the fill light, the positioning plate always remains in contact with the arc-shaped sidewall of the cover during the rotation of the fill light, which can continuously provide lateral support and guidance for the fill light. This effectively limits its radial displacement during rotation and suppresses vibration through contact friction, thereby significantly improving the stability and smoothness of the fill light's rotation.

[0012] According to one embodiment of the present invention, the connector is detachably connected to the PTZ camera body.

[0013] According to one embodiment of the present invention, the PTZ camera body includes a mounting frame, a spherical lens, and a top cover; the mounting frame is rotatable relative to the top cover about the Z-axis; the spherical lens is rotatable relative to the mounting frame about the X-axis.

[0014] According to one embodiment of the present invention, the fill light can swing relative to the upper cover with the X-axis as the axis, thereby enabling the fill light to have a pitch adjustment function, effectively reducing the fill light blind spot, and further ensuring uniform illumination and imaging quality across the entire angle range.

[0015] According to one embodiment of the present invention, the upper end of the mounting bracket is provided with a socket, and the output shaft of the drive unit is plugged into the socket. Through this plugging structure, the drive unit can be stably connected to the mounting bracket.

[0016] According to one embodiment of the present invention, the upper end of the mounting bracket is provided with a slot, and the connector is provided with a post that engages with the slot. The connection between the post and the slot achieves stable positioning of the connector, enabling the fill light to reliably move in conjunction with the connector. At the same time, it simplifies the installation and disassembly process of the fill light assembly and improves the overall assembly efficiency and ease of use and maintenance of the structure.

[0017] According to one embodiment of the present invention, a shoulder bearing is provided between the fixing frame and the upper cover to realize the smooth rotation of the mounting frame relative to the upper cover, effectively reducing rotational resistance and wear, and improving the stability and service life of the PTZ camera body during rotation.

[0018] According to one embodiment of the present invention, an end face bearing is provided between the fixing frame and the upper cover. By utilizing the supporting and guiding effect of the end face bearing, the upper cover can rotate smoothly relative to the fixing frame, further reducing motion friction and improving the overall rotation flexibility and durability.

[0019] According to one embodiment of the present invention, the supplementary light is an LED panel light with wide-angle illumination characteristics, which can provide uniform and wide illumination coverage, effectively improving the brightness and clarity of the monitoring area, especially in low-light environments, ensuring that the camera receives sufficient lighting support and improving video image quality.

[0020] According to one embodiment of the present invention, the mounting bracket is equipped with a battery to provide independent power support for the PTZ camera, ensuring that the equipment can still operate normally when the external power is interrupted or when it needs to be moved for installation.

[0021] According to one embodiment of the present invention, the mounting bracket is equipped with an antenna for wireless communication or signal transmission with external devices, ensuring stable connection of the PTZ camera in application scenarios such as remote control and data transmission.

[0041] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model. Example 1

[0042] like Figure 1-12 As shown, this embodiment discloses a PTZ camera, including:

[0043] The fixed frame 1 has a drive unit 8 inside its cover 11;

[0044] The PTZ camera body is rotatably mounted on the fixed frame 1, and the drive unit 8 is used to drive the PTZ camera body to rotate relative to the fixed frame 1 about the Z-axis.

[0045] The supplementary light 4 is mounted on the fixed frame 1;

[0046] Connector 9 connects the drive unit 8 and the fill light 4, enabling the fill light 4 to rotate synchronously with the PTZ camera body.

[0047] Furthermore, the PTZ camera is mounted on a wall or light pole using a mounting bracket 1 to ensure its stability and adjustability. The mounting bracket 1 includes a housing 11 and a connecting part 12. The connecting part 12 is located at the center of the upper end of the housing 11, ensuring the balance and stability of the entire structure. The housing 11 is circumferentially arc-shaped, and this arc covers at least the entire rotation range when the PTZ camera rotates around the Z-axis, ensuring that the supplementary light 4 provides uniform illumination throughout its rotation. To improve the rotational smoothness of the supplementary light 4 and reduce vibration, a large-area LED panel light (commonly known as a light panel) is used for the supplementary light 4, and a positioning piece 93 is added to the connector 9. This positioning piece 93 is located at one end of the connector 9 and is vertically positioned. When the connector 9 rotates the supplementary light 4, the positioning piece 93 always remains in contact with the arc-shaped sidewall of the housing 11, ensuring more stable rotation of the supplementary light 4 and effectively avoiding offset or vibration problems caused during rotation.

[0048] Specifically, in combination Figure 6 As shown, in this embodiment, the PTZ camera body includes a mounting frame 2, a spherical lens 3, and a top cover 7; the mounting frame 2 is rotatable relative to the top cover 7 about the Z-axis; the spherical lens 3 is rotatable relative to the mounting frame 2 about the X-axis. The fill light 4 is oscillating relative to the top cover 7 about the X-axis.

[0049] Furthermore, in this embodiment, the supplementary light 4 adopts a lamp panel design, with the area of ​​the lamp panel being larger than that of the upper cover 7, ensuring that it can provide wide-angle lighting coverage. One side of the supplementary light 4 is connected to the upper cover 7 via a hinge, a design that allows the supplementary light 4 to be tilted within a certain range as needed. To ensure that the supplementary light 4 can be stably maintained at a specific tilt angle, this embodiment incorporates damping at the hinge point between the supplementary light 4 and the upper cover 7. The function of damping is to provide sufficient friction, allowing the supplementary light 4 to maintain that angle for a long time after being adjusted to a certain tilt angle, avoiding changes in angle due to external vibrations or other factors, and ensuring the stability of the lighting.

[0050] Furthermore, in this embodiment, to further enhance the stability between the supplementary light 4 and the upper cover 7, a spring-loaded latch and an arc-shaped toothed groove are provided between the supplementary light 4 and the upper cover 7. The teeth on the spring-loaded latch engage with the arc-shaped toothed groove, thereby producing a damping effect. This design not only effectively limits the excessive movement of the supplementary light 4 during rotation, but also maintains the stability of the pitch angle of the supplementary light 4 under different operating conditions, avoiding angular deviation caused by vibration or other external factors, thereby improving the service life and stability of the supplementary light 4.

[0051] In other embodiments, a fastener may be provided at the hinge joint between the supplementary light 4 and the upper cover 7, allowing adjustment of the damping between the supplementary light 4 and the upper cover 7 by tightening or loosening the fastener. This design provides additional flexibility, allowing users to adjust the damping effect of the supplementary light 4 according to actual needs. The fastener is preferably a bolt, which allows for easy adjustment of the damping strength, ensuring that the supplementary light 4 maintains the optimal pitch angle under various operating conditions. The specific damping settings in this embodiment employ conventional methods in the art and will not be described in detail here.

[0052] In some other embodiments, the fill light 4 incorporates a motor that drives it to swing relative to the upper cover 7. This design allows the fill light 4 to dynamically adjust its illumination angle according to the rotation of the PTZ camera lens, ensuring that as the PTZ camera 3 rotates around the X-axis, the fill light 4 follows the rotation of the PTZ camera body, always maintaining alignment with the lens's field of view, further enhancing the camera's illumination effect in multi-angle monitoring. This motor-driven approach not only improves the system's flexibility but also simplifies the operation process, avoiding the tediousness of manual adjustments.

[0053] Specifically, in combination Figure 8-9 As shown, the upper end of the mounting bracket 2 is provided with a socket 21, and the output shaft of the drive unit 8 is inserted into the socket 21. Through this insertion structure, the drive unit 8 can be stably connected to the mounting bracket 2. The upper end of the mounting bracket 2 is provided with a slot 22, and the connector 9 is provided with a post 92 that is inserted into the slot 22.

[0054] In this embodiment, the connector 9 is provided with a horizontally arranged platform, and the drive unit 8 is a motor. The output shaft of the motor passes through the platform and is press-fitted with the insertion hole 21 at the center of the upper end of the mounting bracket 2 to ensure the stable installation of the connector 9. The bottom of the connector 9 is provided with a pin 92 to further strengthen the connection with the mounting bracket 2. A connecting post 91 is also provided on the platform, and the connecting post 91 is fixedly connected to the upper cover 7 by screws, thereby realizing the fixed connection of the connector 9 to the supplementary light 4 through the upper cover 7. In order to improve the support performance and reduce frictional resistance during rotation, a shoulder bearing 13 is provided between the fixing bracket 1 and the upper cover 7, and an end face bearing 14 is also provided to ensure good support and guidance effect during pitching motion.

[0055] Furthermore, in this embodiment, the bottom surface of the upper cover 7 is provided with a downwardly extending shaft 71, the outer ring of the shoulder bearing 13 has a shoulder structure, and the connecting part 12 on the fixing bracket 1 is provided with a stepped hole. The shoulder bearing 13 is installed in an inverted manner, with the bearing shoulder tightly abutting the stepped surface on the stepped hole, forming a stable axial positioning. The outer ring of the shoulder bearing 13 is interference-fitted with the smaller diameter portion of the stepped hole, while the inner ring is fixed to the shaft 71 on the upper cover 7 by an interference fit. The shaft 71 is firmly connected to the shoulder bearing 13 by screws and washers, thereby achieving a stable assembly of the upper cover 7 and the shoulder bearing 13. In addition, an end face bearing 14 is provided between the upper end of the connecting part 12 and the inner top surface of the upper cover 7 to further distribute the axial load and improve the smoothness and durability during rotation.

[0056] Specifically, in combination Figure 5 As shown, the mounting bracket 1 is equipped with a battery 6, providing independent power support for the PTZ camera and ensuring that the equipment can still operate normally when the external power is interrupted or when it needs to be moved for installation. The mounting bracket 1 is equipped with an antenna 5 for wireless communication or signal transmission with external devices, ensuring a stable connection for the PTZ camera in applications such as remote control and data transmission.
