[0046] See Figures 1-3 The housing 101 includes an upper housing 1011 and a lower housing 1012. The upper housing 1011 and the lower housing 1012 are connected to each other. The outer wall of the inner support structure 102 is fitted to the inner wall of the upper housing 1011. The inner support structure 102 can be disposed in the cavity of the upper housing 1011.
[0047] See Figures 1-3 The first image acquisition unit 103 includes a first optical lens 1031 and a first image sensor 1032.

The first image sensor 1032 is detachably mounted on one side of the inner support structure 102. The first image sensor 1032 and the first optical lens 1031 are optically coupled.
[0048] For example, the first image sensor 1032 can be positioned opposite to the first optical lens 1031, so that the first image sensor 1032 and the first optical lens 1031 can cooperate to capture image data of the area around the video alarm 100.
[0049] See Figures 1-3 The first motion detection unit 104 can be disposed on the same side as the first image acquisition unit 103.

[0050] The first detection lens 1041 is detachably mounted on one side of the upper housing 1011. The first motion sensor 1042 is detachably mounted on one side of the upper housing 1011. The first motion sensor 1042 and the first detection lens 1041 are optically coupled. The first motion sensor 1042 can be positioned opposite to the first detection lens 1041, thereby enabling the first motion sensor 1042 and the first detection lens 1041 to cooperate in detecting moving objects in the area surrounding the video alarm 100.
[0051] See Figures 1-4 The signal transmission module 105 is detachably connected to the bottom of the upper housing 1011. Furthermore, the signal transmission module 105 is detachably connected to the top of the lower housing 1012. For example, the signal transmission module 105 can be a speaker. The signal transmission module 105 can be used to generate an alarm-like audible signal in the area surrounding the video alarm 100.
[0052] See Figures 1-4 The auxiliary lighting device 106 is detachably disposed around the circumferential sidewall of the lower housing 1012. For example, the auxiliary lighting device 106 may include a lampshade 1061 and an annular flexible lamp panel 1062. The annular flexible lamp panel 1062 may be disposed around the sidewall of the lower housing 1012, and the annular flexible lamp panel 1062 may be attached to the outer sidewall of the lower housing 1012. The lampshade 1061 may be disposed around the outer wall of the annular flexible lamp panel 1062. The auxiliary lighting device 106 may emit white light for illumination and supplementary lighting, and the auxiliary lighting device 106 may also emit red or blue light for alarm and warning purposes.
[0053] Through the above embodiments, the video alarm 100 of this application, by placing the first image acquisition unit 103 and the first motion detection unit 104 on the same side, can reserve expansion space for multiple image acquisition units or multiple motion sensor modules without increasing the size of the video alarm 100. The circular auxiliary lighting device 106 of this application can provide a circular lighting range, thereby expanding the lighting range and providing a uniform lighting effect, making the image data acquired by the first image acquisition unit 103 clearer. The video alarm 100 of this application has a simple structure and is easy to disassemble.
[0054] Optionally, see Figures 1-3The upper shell 1011 is a hollow cylindrical structure. The upper shell 1011 may include an upper shell wall 10111 and an upper side shell wall 10112. The upper side shell wall 10112 surrounds the upper shell wall 10111. The upper side edge of the upper side shell wall 10112 is fixedly connected to the perimeter of the upper shell wall 10111. A window is provided on one side of the upper shell 1011, which is also a window on one side of the upper side shell wall 10112. The lower shell 1012 is a hollow cylindrical structure. The lower shell 1012 includes a lower shell wall and a lower side shell wall. The lower side shell wall surrounds the lower shell wall, and the lower side edge of the lower side shell wall is fixedly connected to the perimeter of the lower shell wall.
[0055] The first optical lens 1031 is detachably mounted on the first mounting plate 116. The shape and size of the first mounting plate 116 are adapted to a window on one side of the upper housing 1011, that is, the shape and size of the first mounting plate 116 are adapted to a window on one side of the upper housing wall 10112. The first mounting plate 116 can be glued to the window on one side of the upper housing wall 10112, and a waterproof feature can be provided between the first mounting plate 116 and the window on one side of the upper housing wall 10112.
[0056] The first image sensor 1032 is detachably mounted on the second mounting plate 117. The second mounting plate 117 is detachably mounted on the side of the inner support structure 102. For example, the second mounting plate 117 can be fixedly connected to the side of the inner support structure 102 by screws. A gap is formed between the second mounting plate 117 and the first mounting plate 116. The second mounting plate 117 and the first mounting plate 116 are arranged parallel to each other in the vertical direction so that the first image sensor 1032 is optically coupled to the first optical lens 1031.
[0057] The first detection lens 1041 is detachably mounted on the first mounting plate 116 in the vertical direction relative to the first optical lens 1031. The first motion sensor 1042 is detachably mounted on the second mounting plate 117 in the vertical direction relative to the first image sensor 1032, so that the first detection lens 1041 is optically coupled to the first detection lens 1041.

[0061] The processing unit includes a processor and a camera application. The camera application configures the processor to: keep the first image acquisition unit 103 in a low-power state; and keep the auxiliary lighting device 106 in a power-off state.
[0062] When the first motion detection unit 104 detects an object within the field of view of the first image acquisition unit 103, the processor receives input from the first motion detection unit 104. In response to receiving input from the first motion detection unit 104, the processor generates a first output to the first image acquisition unit 103, causing the first image acquisition unit 103 to power on and record image data from the field of view. In response to receiving input from the first motion detection unit 104, the processor generates a second output to the auxiliary lighting device 106, causing the auxiliary lighting device 106 to power on and illuminate the field of view of the first image acquisition unit 103. In response to receiving input from the first motion detection unit 104, the processor generates a third output to the communication unit, causing the processor to initiate a call to a backend device via an external communication network. In response to receiving input from the first motion detection unit 104, the processor generates a fourth output to the signal transmission module 105, causing the signal transmission module 105 to power on and emit alarm information (e.g., an alarm sound).
[0063] Through the above embodiments, the video alarm 100 provided in this application can, when the first motion detection unit 104 detects a moving object, control the response of the first image acquisition unit 103, the auxiliary lighting device 106 and the communication unit through the processing unit, thereby calling the back-end device.

[0070] For example, the first detection lens 1041 can be a large-angle PIR detection lens, so that the first motion sensor 1042 and the second motion sensor 1101 are optically coupled together with the large-angle PIR detection lens. The angle range of the large-angle PIR detection lens and the number of the second motion sensors 1101 can be adjusted according to actual usage.
