Thus, the positioning and fixing effects on the image pickup body 31 of the image pickup module 30 can be improved by increasing the number of the engaging portions 11. When the connecting base 313 is in a square structure, the two clamping portions 11 can be respectively clamped at two opposite sides of the diagonal of the connecting base 313, so as to improve the clamping and fixing effect of the clamping portion 11 on the whole connecting base 313.

Illustratively, the positioning member 3131 may be disposed on the connection base 313, the positioning groove 331 may be formed on the first circuit board 33, or the positioning member 3131 may be disposed on the first circuit board 33, and the positioning groove 331 may be formed on the connection base 313. Under such setting, in the assembly process of the actual connection base 313 and the first circuit board 33, the positioning piece 3131 and the positioning groove 331 can be matched to realize the pre-positioning of the two, and the two are fixedly connected after the pre-positioning is finished, such as threaded connection, welding and the like, so that the assembly of workers is facilitated, and the assembly efficiency is improved.

In the above, the monitoring device 100 of the present application has been described in terms of the form of the snap-fit engagement of the snap-fit portion 11 and the camera module 30, and has the advantage of being accurate and convenient to install. On this basis, referring to fig. 6, in order to improve the monitoring effect of the monitoring device 100, the number of the camera assemblies 30 may be at least two, and at least two camera assemblies 30 may be arranged at intervals along the horizontal direction of the housing 10. If one camera assembly 30 is used for shooting and monitoring, the camera assembly 30 is affected by the limited angle of the field of view, which results in too small an angle of the image shot by the monitoring device 100. Therefore, to realize a large-angle monitor screen, two or more image pickup modules 30 are required to perform screen stitching. And through on the mounting window 10a of casing 10 can be pre-fixed to at least two subassembly 30 of making a video recording in advance to the joint portion 11 of casing 10, can guarantee the accuracy of at least two subassembly 30 of making a video recording final position on casing 10 to in the equipment in-process can guarantee the equipment precision of at least two subassembly 30 of making a video recording on casing 10, through the quantity setting of at least two subassembly 30 of making a video recording, can make monitoring device 100 can possess the accuracy that has the picture of the control of great angle and make a video recording between the subassembly 30 of making a video recording, in order to further improve user experience. The image capturing assembly 30 may be, for example, two, three, four, or the like, without limitation.

In an embodiment, an included angle formed by the optical axes of the lenses 311 of the image capturing bodies 31 of the adjacent two image capturing modules 30 is greater than or equal to 85 degrees and less than or equal to 90 degrees. When the horizontal viewing angle range of the lens 311 of each image capturing body 31 is 85 degrees to 90 degrees, on the basis that the included angle formed by the optical axes of the two lenses 311 is greater than or equal to 85 degrees and less than or equal to 90 degrees, the horizontal viewing angle of the imaging area formed by the two adjacent image capturing components 30 can reach more than 160 degrees, thereby playing a larger-range monitoring effect. Illustratively, the included angle formed by the optical axes of the lenses 311 of the image capturing bodies 31 of the adjacent two image capturing modules 30 may be set to 85 degrees, 86 degrees, 87 degrees, 88 degrees, 89 degrees, 90 degrees, or the like, which is not limited.

When the horizontal viewing angle range of the lens 311 of each image capturing body 31 is 85 degrees to 90 degrees, the shooting range that the lens 311 of the image capturing body 31 can reach is larger, so that the monitoring range that the monitoring device 100 can reach is larger, thereby improving the monitoring range of the monitoring device 100, and also ensuring that the imaging distortion obtained by shooting the lens 311 is not excessive due to the overlarge horizontal viewing angle range of the lens 311, so as to avoid affecting the final imaging quality of the lens 311 of the image capturing body 31. When the horizontal angle of view is greater than 90 degrees, the final imaged image of the lens 311 is easily distorted too much due to the excessively large angle of view, resulting in poor final imaging effect. When the horizontal angle of view is less than 85 degrees, the monitoring range that can be achieved by the lens 311 is small. Therefore, the present application can ensure that the lens 311 of the image pickup body 31 has a large monitoring range, and ensure the imaging effect of the final imaging picture. Specifically, the horizontal angle of view of the lens 311 of each image pickup body 31 may be 85 degrees, 86 degrees, 87 degrees, 88 degrees, 89 degrees, 90 degrees, or the like, which is not limited.

When the included angle formed by the optical axes of the lenses 311 of the image capturing bodies 31 of the adjacent two image capturing modules 30 is 85 degrees or more and 90 degrees or less, the above-described configuration may be realized by selecting the orientation of the lenses 311 of the image capturing bodies 31. Specifically, the wall surface of the housing 10 may be an arc surface, and by providing the arc surface with the mounting windows 10a with different angles, when the lens 311 of the image capturing main body 31 is inserted into the different mounting windows 10a, the angles of the lenses 311 of the different image capturing main bodies 31 are changed. Of course, the wall surface of the housing 10 may include a plurality of spliced flat surfaces, the flat surfaces are disposed with an included angle therebetween, and an installation window 10a is disposed on one flat surface, so that the angle of the lens 311 of the image body can be changed when the lens is disposed through different installation windows 10a.

In the illustrated embodiment, the number of light compensating assemblies 50 corresponds to the number of camera assemblies 30, and a light compensating assembly 50 is disposed adjacent to a camera assembly 30. So can make a video recording subassembly 30 through a light filling subassembly 50 to the corresponding light filling, guarantee the shooting effect of every subassembly 30 of making a video recording. Of course, the number of the light compensating assemblies 50 can be one, for example, one light compensating assembly 50 is located between two adjacent image capturing assemblies 30, so as to realize the light compensating function of two image capturing assemblies 30 through one light compensating assembly 50, thereby reducing the number of the light compensating assemblies 50 and reducing the production cost.

In the actual assembly process, the included angle between the light compensating lamps 51 of the two adjacent light compensating assemblies 50 and the included angle formed by the optical axes of the lenses 311 of the image capturing bodies 31 of the two adjacent image capturing assemblies 30 may be set to be the same, so as to further improve the light compensating effect. Meanwhile, when the second circuit board 53 and the lamp cup 55 of the light supplementing assembly 50 are selected and the mounting positions are selected, the shape selection and the mounting positions of the second circuit board 53 and the lamp cup 55 can be selected according to the determined included angles of the light supplementing lamps 51 of two adjacent light supplementing assemblies 50, so that the model selection and the mounting positions of the second circuit board 53 and the lamp cup 55 can be determined conveniently by staff.
