[0002] Surveillance cameras, also known as surveillance cameras, are quasi-cameras used in security. They have higher pixels and resolution than computer video heads. Network cameras are a new generation of cameras that combine traditional cameras with network technology. They can transmit video images to the other side of the earth through the network, and remote viewers do not need to use any professional software. They can monitor their video images with a standard network browser. They are generally composed of lenses, image sensors, sound sensors, signal processors, encoding chips, networks, and control interfaces. The overall layout of existing network camera monitoring equipment is not compact enough. Usually, the control circuit inside the surveillance camera is powered by an external power cord, which has the problem of limited installation environment. When the control circuit inside the surveillance camera is powered by an external power cord, it will need to record for a long time when powered on, thereby occupying a large amount of memory and consuming power resources. In addition, the internal circuit control structure of existing network surveillance cameras is complex, and sensitive components are easily affected by high working temperatures and become unstable.

[0023] Specifically, the Ethernet connector 10 can use various types of connectors such as RJ45 and RJ11 to connect to the external network cable, and remotely transmit the image data captured by the monitoring camera 7 to the terminal device through the network cable for real-time viewing. The power supply communication connector 10 (i.e., the power connector), also known as a connector, is a device that connects two active devices and transmits current or signals. In this embodiment, a circular connector is used, and other types of connectors can also be used in other preferred embodiments. The two connectors (i.e., the power supply communication connector 11 and the Ethernet connector 10) are compact in structure. After being installed in conjunction with the middle box body 13, the overall structure of the monitoring camera is compact, not limited by the installation position, and can realize real-time data transmission and remote signal control, further saving the internal storage space of the monitoring camera 7.

[0024] More specifically, the middle box body 13 of the present embodiment is provided with two installation openings which are relatively arranged. The front cover assembly is connected and fixed to one installation opening by means of screws, and the rear cover 9 is also connected and fixed to the other installation opening by means of screws. A perspective window is provided in the middle of the front cover assembly for the monitoring camera to obtain external images. Specifically, countersunk screws are used to fix the front cover assembly and the rear cover 9 to the middle box body 13. A grounding column 8 is also installed on the side of the middle box body 13. The specific installation position is arranged relative to the installation position of the power supply communication connector 11 and the Ethernet connector 10, and both are located on the field of view side of the monitoring camera 7, which further makes the appearance structure of the monitoring camera compact.

[0025] In this embodiment, an annular limiting boss 14 coaxial with the installation cavity is provided near the front cover assembly of the installation cavity, and a mounting hole is provided in the middle of the annular limiting boss 14, and the monitoring end of the monitoring camera 7 is passed through and fixed in the mounting hole.

[0026] Specifically, the annular limiting boss 14 is integrally formed with the middle box body 13, and specifically, rust-proof aluminum (5A06) is selected. The screws and other parts used to connect the middle box body 13 with the front cover assembly and the rear cover 9 are made of 316 stainless steel because of their small size and high strength, good wear resistance, corrosion resistance, and beautiful appearance. The surface is passivated. The aforementioned grounding column 8 is made of copper, and the surface is nickel-plated to prevent oxidation of the copper while ensuring its conductivity.

[0027] In this embodiment, the surveillance camera also includes a control circuit board 71, which is connected to the surveillance camera 7 through wires, and is also connected to the middle box body 13 through wires.
