[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0024] Refer to the attached Figure 1-5 An Internet monitoring and early warning device includes a monitoring camera 1 and a two-degree-of-freedom camera pan-tilt bracket 2. The monitoring camera 1 is rotatably mounted on the output rotating element of the two-degree-of-freedom camera pan-tilt bracket 2. The two-degree-of-freedom camera pan-tilt bracket 2 is composed of a two-degree-of-freedom steering gear, and the output rotating element of the two-degree-of-freedom steering gear is fixedly connected to the monitoring camera 1. The two-degree-of-freedom steering gear is a steering gear. Compared with an ordinary single-degree-of-freedom steering gear, it can make the monitoring camera 1 produce two independent degrees of freedom of movement, which means that it can control the monitoring camera 1 to move on two independent planes, such as pitching movement on a vertical plane and shaking head movement on a horizontal plane;

[0025] In this embodiment, a plurality of small holes 6 inclined downward are provided at the lower end of the shell in the two-degree-of-freedom camera pan-tilt bracket 2, and the plurality of small holes 6 are respectively provided on the periphery of the monitoring camera 1, and the shell portion on which the plurality of small holes 6 are provided on the two-degree-of-freedom camera pan-tilt bracket 2 is specifically made of explosion-proof steel, and an installation slot 4 is provided inside the above-mentioned shell, and the installation slot 4 and the plurality of small holes 6 are connected to each other.

[0026] In this embodiment, a lithium battery 5 is fixedly installed on the inner bottom surface of the installation slot 4, and the lithium battery 5 is connected in series with a number of miniature cameras 3 through wires. The several miniature cameras 3 are fixedly hidden and installed in a number of small holes 6, respectively. Multi-angle monitoring and early warning, that is, the several miniature cameras 3 are respectively installed on explosion-proof steel, and the several miniature cameras 3 and the lithium battery 5 are protected by a shell made of explosion-proof steel. The lithium battery 5 is connected to an electromagnetic switch 7 through a wire, and the shell of the electromagnetic switch 7 is fixedly installed in the installation slot 4.

[0027] In this embodiment, a movable iron core 8 is telescopically installed in the shell of the electromagnetic switch 7, and a brass sheet 11 is fixedly installed at the end of the movable iron core 8. The outer diameter of the brass sheet 11 is larger than the outer diameter of the movable iron core 8. A reset spring 9 is arranged on the periphery of the movable iron core 8. The two ends of the reset spring 9 are respectively squeezed and installed between the shell of the electromagnetic switch 7 and the end of the brass sheet 11. The brass sheet 11 of the movable iron core 8 is in contact with a copper block 10, and the brass sheet 11 and the copper block 10 are respectively connected in series through wires and a number of miniature cameras 3.

[0028] It should be added that Figure 5 The two servos in the two-degree-of-freedom servo, the surveillance camera 1, the electromagnetic switch 7 and the lithium battery 5 are respectively connected to the external 220V AC power through the wire and the electromagnetic switch 7, and the lithium battery 5 is connected to the plurality of micro cameras 3 through the copper block 10, the brass sheet 11 and a plurality of wires, and the plurality of micro cameras 3 are connected in parallel with each other;

[0029] It is further supplemented that the circuits in the surveillance camera 1 and the electromagnetic switch 7 are connected by wires. When the surveillance camera 1 is working normally, the electromagnetic switch 7 is also in a powered-on state. When the surveillance camera 1 is damaged and powered off, the electromagnetic switch 7 is also in a powered-off state. As is known to all, when the electromagnetic switch 7 is powered on, the electromagnet coil in the electromagnetic switch 7 will generate electromagnetic attraction to attract the movable iron core 7 to close the contact, thereby connecting the circuit between the lithium battery 5 and the external 220V AC power. That is, when the surveillance camera 1 is working normally, the external 220V AC power always charges the lithium battery 5 to ensure that sufficient electrical energy is stored in the lithium battery 5.

[0030] When the surveillance camera 1 is damaged and powered off or the external power line is cut off, the electromagnetic switch 7 is also in a power-off state. The electromagnet coil in the electromagnetic switch 7 will not generate electromagnetic force, and the compressed return spring 9 pushes the movable iron core 8 and the brass sheet 11 to approach the copper block 10, and connects the copper block 10 and the brass sheet 11, connecting the circuits in several miniature cameras 3 and the lithium battery 5, and the miniature cameras 3 in working state continue to perform early warning monitoring and image storage for a certain period of time.

[0031] The utility model firstly makes the shell part of the two-degree-of-freedom camera pan-tilt bracket 2 of explosion-proof steel, which can ensure that the plurality of micro cameras 3 and lithium batteries 5 therein will not be damaged by criminals, and the micro cameras 3 are hidden and installed in the plurality of small holes 6, which are not easy to be found, and the plurality of micro cameras 3 are arranged at multiple points, which can monitor the scene of the destruction of the surveillance camera 1 from multiple angles;

[0032] When the surveillance camera 1 is damaged by being smashed and powered off or the external power line is cut off, the electromagnetic switch 7 is also in a power-off state at the same time, and the electromagnet coil in the electromagnetic switch 7 will not generate electromagnetic force. The compressed return spring 9 pushes the movable iron core 8 and the brass sheet 11 close to the copper block 10, and connects the copper block 10 and the brass sheet 11, connecting the circuits in several miniature cameras 3 and the lithium battery 5. The miniature cameras 3 in working state continue to perform early warning monitoring and image storage on the scene for a certain period of time, which is mainly used to monitor who destroyed the surveillance camera 1 and what the destroyer did. The wireless network signal transmission mechanism can also be used to transmit monitoring signals in real time.
