Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0027] The technical solutions disclosed in various embodiments of the present application are described in detail below in conjunction with the accompanying drawings.

[0028] Please refer to Figures 1 to 5 The embodiment of the utility model discloses a camera device, which can be applied to a security system. The disclosed camera device includes a base 10 and a camera body 20.

[0029] The base 10 is a basic component of the camera device. The base 10 not only provides an installation position for the camera body 20, but is also used to connect to the installation base of the camera device (such as a roof, wall, etc.), thereby realizing the installation of the entire camera device.

[0030] The camera body 20 is the main part of the camera device, and the camera body 20 is responsible for shooting images. The camera body 20 is connected to the base 10 to achieve installation on the base 10. In one embodiment, the camera body 20 can be fixedly connected to the base 10, thereby achieving directional shooting of the camera device. In another embodiment, the camera body 20 can be rotatably connected to the base 10, thereby achieving multi-directional flexible shooting of the camera device. It should be noted that the embodiment of the utility model does not limit the specific connection method between the camera body 20 and the base 10.

[0031] In the embodiment of the present invention, the base 10 includes a PON interface 13 , and the PON interface 13 is used for optical-electrical connection with the optical-electrical composite cable 30 .

[0032] When the camera device is working, the camera device will receive a control signal for controlling the camera device, and the camera device will also output the image information obtained during the shooting process. The optoelectronic composite cable 30 can not only transmit optical signals, but also provide electrical energy for the camera device. After the optoelectronic composite cable 30 is optically connected to the PON interface 13, it plays the function of optical signal transmission and power supply. Specifically, the camera device is used to power the camera device through the optoelectronic composite cable 30, receive the control signal for controlling the camera device in the form of an optical signal, and output the image signal obtained by the camera subject 20 in the form of an optical signal. Specifically, the control signal and the image signal are transmitted in the optoelectronic composite cable 30 in the form of an optical signal.

[0033] The camera device disclosed in the embodiment of the utility model designs the base 10 to include a PON interface 13, so that the PON interface 13 can be photoelectrically connected to the photoelectric composite cable 30. The photoelectric composite cable 30 transmits photoelectric signals and supplies power by using cables and optical fibers. Optical fiber communication has the advantages of fast transmission speed and large information transmission capacity, so that data can be transmitted without compression, thereby meeting the immediacy requirements of the security system. This method of transmitting through optical signals does not require a POE switch, which can reduce the user's cost of use. Moreover, the use of the PON interface 13 to photoelectrically connect with the photoelectric composite cable 30 can enable the photoelectric composite cable 30 to not only transmit data, but also supply power without an external power supply, which can further reduce the user's cost of use.

[0034] In one embodiment of the present invention, the optoelectronic composite cable 30 can be directly connected to the camera body 20 or the control module in the camera device through the PON interface 13. In other embodiments, the base 10 can also include a base housing 11, a circuit board 12 and a processor 14.

[0035] The base housing 11 is a peripheral component of the base 10, and the base housing 11 can provide a mounting base for other components of the base 10. The camera body 20 is connected to the base housing 11, thereby realizing the connection with the base 10. Similarly, in one embodiment, the camera body 20 and the base housing 11 can be fixedly connected, thereby realizing the fixed connection between the camera body 20 and the base 10. In another embodiment, the camera body 20 and the base housing 11 can be rotatably connected, thereby realizing the rotatable connection between the camera body 20 and the base 10.

[0036] The circuit board 12 is arranged inside the base housing 11. Specifically, the circuit board 12 can be fixed inside the base housing 11, so as to achieve fixed installation inside the base housing 11. The processor 14 is essentially a processing chip, and the processor 14 can also realize the conversion between electrical signals and optical signals.

The processor 14 is arranged on the circuit board 12. The PON interface 13 is arranged on the circuit board 12. The circuit board 12 not only provides an installation position for other components (such as the processor 14, the PON interface 13, etc.) arranged thereon, but also, if necessary, the circuit board 12 can also serve as a medium for power supply connection and communication connection (including optical signal communication) between corresponding components (such as between the processor 14 and the PON interface 13, and for example between the processor 14 and the ALARM output interface 16 described later), so as to realize the power supply connection and communication connection between the corresponding components.

[0037] The interface end of the PON interface 13 is exposed outside the base housing 11 and is used for optical connection with the optoelectronic composite cable 30. The processor 14 is used to convert the control signal presented in the form of an optical signal transmitted by the optoelectronic composite cable 30 into an electrical signal. The processor 14 is also used to convert image information presented in the form of an electrical signal into an optical signal. This structure can realize the conversion between optical signals and electrical signals, thereby facilitating the transmission of optical signals between the camera device and other components.

[0041] Specifically, the plurality of wire pressing protrusions 1122 can be arranged on the same notch edge of the wire winding groove 1121. In other embodiments, the plurality of wire pressing protrusions 1122 can be staggeredly distributed on two opposite notch edges of the wire winding groove 1121, so as to realize staggered compression and can also compress both sides of the optoelectronic composite cable 30 respectively, which is conducive to improving the compression effect.

Specifically, the cover 112 may have a recess 1123, and the avoidance hole 1124 may be opened on the side wall of the recess 1123. In this case, the recess 1123 may accommodate part of the optoelectronic composite cable 30, and the recess 1123 may be connected to the cable winding groove 1121, so that when part of the optoelectronic composite cable 30 is accommodated in the cable winding groove 1121, it can be partially accommodated in the recess 1123 to facilitate wiring in the cable winding groove 1121.

[0043] As described above, the camera body 20 and the base housing 11 can be connected to each other in rotation, so as to achieve multi-directional shooting.
