[0034] This utility model proposes a radar-assisted intelligent network camera. Please refer to [reference needed]. Figures 1-3 The intelligent network camera includes a vision component 1, a camera body 2, the vision component 1 being rotatably mounted on the camera body 2, a base 3, the camera body 2 being rotatably mounted on the base 3, a control unit being installed inside the base 3, and a first radar detection unit 23 and a second radar detection unit 24 being installed inside the camera body 2. The first radar detection unit 23 and the second radar detection unit 24 are respectively located on opposite sides of the vision component 1. Both the first radar detection unit 23 and the second radar detection unit 24 are electrically connected to the control unit, and the control unit is electrically connected to the vision component 1. The vision component 1 rotates in coordination with the first radar detection unit 23 and the second radar detection unit 24 to quickly detect blind spots.

[0035] Please refer to Figure 2The above design effectively solves the problems of insufficient blind spot coverage and delayed response under the fixed view of traditional cameras or single radar assistance by cooperating with the first radar detection unit 23 and the second radar detection unit 24 symmetrically arranged on both sides of the camera body 2 for detection, combined with the dynamic linkage mechanism of the control unit. Secondly, the dual radars monitor the blind spot targets on both sides of the vision component 1 in real time, triggering the camera to turn quickly to track, which significantly shortens the target acquisition time. Furthermore, the integrated design of the first radar detection unit 23 and the second radar detection unit 24 built into the camera body 2 reduces the size and cost of the equipment while improving the ease of installation. Finally, the characteristics of the first radar detection unit 23 and the second radar detection unit 24 being unaffected by light enhance the all-weather monitoring capability in complex environments, ultimately achieving efficient, accurate and low-power blind spot elimination and dynamic target tracking.

[0036] In this embodiment, the camera body 2 includes a camera housing 21 and a mid-frame 22 disposed inside the camera housing 21. The first radar detection unit 23 and the second radar detection unit 24 are fixed to the outside of the mid-frame 22 by corresponding connectors 25. This arrangement is used to fix the position of the first radar detection unit 23 and the second radar detection unit 24, preventing the first radar detection unit 23 and the second radar detection unit 24 from shifting due to external force, which would change the detection angle range and affect the vision component 1's tracking of the target. Furthermore, since the detection angle ranges of the first radar detection unit 23 and the second radar detection unit 24 do not overlap, the target in the blind spot of the vision component 1 in the current state can be detected, which is convenient for the vision component 1 to track and monitor the target from all directions.

[0037] It should be noted that in this embodiment, the detection range of both the first radar detection unit 23 and the second radar detection unit 24 is 120 degrees.

[0038] In this embodiment, the connector 25 includes several fastening bolts for fastening the first radar detection unit 23 and the second radar detection unit 24 in a predetermined position. In fact, in other embodiments, the connector 25 may also be a screw or a snap-fit ​​structure, as long as it can stably and securely fasten the first radar detection unit 23 and the second radar detection unit 24 in a predetermined position.

[0039] For details, please refer to Figure 2 The camera housing 21 is equipped with a first drive motor 26. The output end of the first drive motor 26 is connected to a first rotating shaft 27. The end of the first rotating shaft 27 away from the first drive motor 26 is rotatably connected to the base 3. This arrangement is used to enable the camera body 2 to rotate along its axial direction, thereby changing the orientation of the vision component 1, so that the vision component 1 can track the target in its side blind zone.

[0040] For further details, please refer to... Figure 2 and Figure 3 The vision component 1 includes a vision housing, a vision processing unit 13, a second rotating shaft 12, and a second drive motor 11. The vision processing unit 13 is embedded on the surface of the vision housing, and the second drive motor 11 is disposed inside the vision housing. One end of the second rotating shaft 12 is connected to the output end of the first drive motor 26, and the other end passes through the vision housing and is rotatably connected to the camera body 2. This arrangement enables the vision component 1 to rotate, thereby adjusting the detection range of the vision processing unit 13.

[0041] In this embodiment, please refer to Figure 2 and Figure 3 The camera housing 21 includes wires inside. The end of the camera housing 21 facing the base 3 is provided with a wire groove. The end of the base 3 facing the wire groove is provided with a mounting plate 31. The mounting plate 31 is provided with a protective element 311. The wires pass through the wire groove and the protective element 311 and enter the interior of the base 3. The protective element 311 includes a protective plate. The protective plate is provided with a slot 3111 for the wires to follow the rotation path of the camera body 2. The above configuration can prevent the wires located between the camera body 2 and the base 3 from getting tangled and damaged when the camera body 2 rotates. On the other hand, it can also reduce the resistance encountered when the camera body 2 rotates, making the camera body 2 rotate more flexibly, thereby quickly realizing the vision component 1 to track the target for monitoring. In other words, this design further improves the sensitivity of the intelligent network camera.

[0042] Following on from the above, please refer to... Figure 3 In this embodiment, the slot 3111 is curved, which ensures that the wire located between the camera body 2 and the base 3 can move smoothly with the rotation direction of the camera body 2.

[0043] In this embodiment, an annular pad 32 is provided on the side of the base 3 away from the camera body 2. This is to prevent damage to the wall or other flat surface when the smart network camera is fixed to the wall or other flat surface due to prolonged contact. Secondly, when the smart network camera is placed on the table, the annular pad 32 enhances the friction effect, making the smart network camera more stable on the table.

[0044] Firstly, it should be noted that, under normal circumstances, the vision component 1 tracks targets already within its visual range. When the target moves, the vision component 1 rotates accordingly for real-time monitoring. However, when a distant target approaches the vision component 1 but is located in the blind spot of the vision component 1 in its current state, the vision component 1 cannot detect and track the target. Therefore, it is necessary to set up other detection devices in the blind spot of the vision component 1. This invention overcomes the above-mentioned defects by using a first radar detection unit 23 and a second radar detection unit 24. The first radar detection unit 23 and the second radar detection unit 24, located inside the camera housing 21, can detect targets in the blind spot of the vision component 1. Then, through the control unit, the signal is transmitted to the camera body 2 and the vision component 1. After receiving the corresponding data, the camera body 2 and the vision component 1 rotate accordingly, enabling the vision component to track the target and thus perform monitoring.

[0045] The above description is only an optional embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
