Description

Network camera module and network camera using same

Technical Field

The utility model relates to a network camera module and use network camera of this network camera module, especially a network camera module and use this network camera module with radar detection unit as the driving source.

Background

The network Camera (IP Camera) generally includes a Camera module, an image compression module, a network communication module, and a microprocessor. Unlike video cameras (webcams) which need to be networked by controlling the connection of a computer, each Webcam can be directly connected to the network as a network device or indirectly connected via a hub, since it has its own IP address. This condition allows it to have the capability of point-to-point (Peer-to-Peer) communication. With the rapid development of the internet of things and the demand of people for safe life, the demand and the application range of the network camera are wider and wider.

The network camera is not generally applied to video communication between people, but is used in a specific location to perform image (sometimes including sound) monitoring and searching for people and things within a certain range, and then immediately transmits the monitored and searched data to a remote receiving end (such as a server) through a network, even through APP cooperation, the data is presented on a mobile communication device of a third party. Traditionally, the same work is done by the monitor. The monitor transmits the image in a wired manner, and the pipeline is a coaxial cable. Coaxial cables are less prone to signal interference and have high reliability and reliability, and therefore are long-standing terminal devices of monitoring systems. However, the monitor is routed to allow for the routing of cables and wires, i.e., the monitor is located in a position that allows for the installation of these wires, whether exposed or enclosed in a particular conduit. This is clearly an unavoidable burden for the erector. If the monitor cannot operate effectively due to the problem of the wired circuit, the maintenance is very troublesome.

In addition, the network camera usually obtains a constant image for a long time during the operation, i.e. the monitored object or environment is not changed, but it consumes a lot of power to operate. Therefore, in order to save unnecessary power cost, recent network cameras have been designed to be in a sleep/standby state. These webcams have added an independent background light detector, which allows the camera module of the webcam to go to sleep and not operate when no substantial change in the image is detected, and to wake up the camera module when a change in the light source (start-up factor) is detected. Background light detectors such as infrared sensors are commonly used. One application scene is that a network camera is used for monitoring entrance and exit of a gate, and when no guest enters a detection range, a camera module is dormant; when a guest appears, the infrared sensor detects that the light source in the detection range is changed, the camera module is driven to recover the operation, and the network camera can even inform monitoring personnel of visiting. The infrared sensor has the advantages of low price and convenient assembly; however, it has the disadvantages of short monitoring distance, small monitoring angle, low accuracy and no provision of multiple identification functions.

On the other hand, the network camera has several problems. First, the network camera is driven by external power as in a general monitor. Although the trouble of a coaxial cable is avoided, the erection of a power line also needs to consider the power supply condition (whether a power socket exists or not) of the position where the network monitoring camera is located and the damage degree of the environmental vision. For the manufacturer, the same type of network monitoring camera may be sold in different countries or regions, and different plugs and voltage transformation devices are replaced, and the power line may be the first natural enemy of the network monitoring camera.

Therefore, consider the problem of above current network monitoring camera product face, the utility model discloses the designer accumulates the experience of several decades in the work of supervisory equipment field, proposes a network camera module and use this network camera module with radar detection unit as the driving source to all problems are once solved to the hope.

Detailed Description

The invention will be further described with reference to the accompanying drawings and specific embodiments, which are illustrative of the invention and are not to be construed as limiting the invention.

Please refer to fig. 1, which is a functional block diagram of a network camera module 10 according to an embodiment of the present invention. The network camera module 10 includes a printed circuit board 100, a video recording unit 110, a radar detection unit 120, a wireless communication unit 130, a memory card slot 140, a light supplement unit 150, a radio unit 160, and a power management unit 170. The function of each element and the connection and interaction with other elements are described in detail below.

The printed circuit board 100 has a plurality of traces (trace), which may be made of copper foil or gold foil. The printed circuit board 100 functions to supply power or signal connections between components mounted thereon. A first trace of the plurality of traces forms a receiving antenna 101 and a second trace forms a transmitting antenna 102. The positions and functions of the receiving antenna 101 and the transmitting antenna 102 will be described below.

The camcorder unit 110 is mounted on the printed circuit board 100, and includes: a processor 111, an image sensor 113, a lens 114, and a data register 115. The processor 111 controls the operation of the electrical connection elements, i.e. the core elements for operating the network camera module 10, and may be an integrated circuit. In the embodiment, the processor 111 is electrically connected to the image sensor 113, the data register 115, the radar detection unit 120, the wireless communication unit 130, the memory card slot 140, the light supplement unit 150, the sound receiving unit 160 and the power management unit 170, and these elements or secondary elements are controlled by the processor 111. The processor 111 may include or be connected to necessary firmware (not shown), such as EEPROM, for burning code that controls the aforementioned devices or secondary devices.

The image sensor 113 is electrically connected to the processor 111 for capturing images and converting the images into electrical image signals, which are provided to the processor 111. The processor 111 can reconstruct the image electrical signal into a specific image file (such as jpg file, mp4 file, etc.) for providing specific applications. The processor 111 may also output the video electrical signal in a streaming manner. In the present embodiment, the image sensor 113 is a CMOS image sensor; in other embodiments, the image sensor 113 may also be a CCD image sensor. Any device capable of effectively converting an optical image into an optical signal is within the scope of the present invention.

To better understand the function of the lens 114 and the configuration of the integral camcorder unit 110 in the network camera module 10, please refer to fig. 2, which is a schematic cross-sectional view of the camcorder unit 110 and the printed circuit board 100. The lens 114 functions to focus light emitted from a portion of the light sources in the direction F of the video image, and the image sensor 113 is aligned with the focal point of the lens 114. Thus, when the lens 114 adjusts its focus, the image sensor 113 can receive the light of the image in the specific range, so as to record the image. In practice, the lens 114 may be a wide-angle lens, a fisheye lens or a retractable lens, and is set according to different requirements. It is noted that the camera unit 110 is located between the receiving antenna 101 and the transmitting antenna 102, and the normal direction N of the receiving antenna 101 and the transmitting antenna 102 is substantially parallel to the camera direction F of the camera unit 110. Such a design allows the radar detection unit 130 to receive and transmit electromagnetic waves through the receiving antenna 101 and the transmitting antenna 102, so as to effectively cover the range of the video recording unit 110 for receiving images. Because the camcorder 110 is not in operation at any time but triggered by the processor 111, the processor 111 must be notified by the radar detection unit 120 to initiate the trigger, and if the trigger source determined by the radar detection unit 120 is not within the range of the camcorder 110 for executing the video recording, the operation of the network camera module 10 will not be wasted.

In addition, the data register 115 of the camcorder 110 is electrically connected to the processor 111, and can temporarily store the image electrical signal from the image sensor 113. In the present embodiment, the data register 115 is a random access memory module; in other embodiments, the data register 115 may be a flash memory module, or even a combination of RAM and flash memory.

The radar detection unit 120 is mounted on the printed circuit board 100, electrically connected to the processor 111 of the camcorder 110 and in signal communication with the receiving antenna 101 and the transmitting antenna 102, and functions to transmit an electromagnetic wave of a specific frequency through the transmitting antenna 102 and receive a reflected wave of the electromagnetic wave from an external object through the receiving antenna 101. In the present embodiment, in order to record images within the effective range of 10 meters and achieve the effect of 0.8m of distance resolution, the electromagnetic wave emitted from the transmitting antenna 102 is a micrometer wave, the frequency thereof may be, for example, 24.15GHz, and the direction of the electromagnetic wave emitted from the transmitting antenna 102 is within a substantial range of 90 ° left and right and 20 ° up and down in the normal direction thereof. In addition, when the radar detection unit 120 detects a newly added reflected wave or a disappeared reflected wave of an object, a trigger signal is sent to the processor 111 to start the camcorder unit 110. Thus, if the video recording result of the video recording unit 110 is not changed, the processor 111 can command the video recording unit 110 to stop operating; once a new target object or an existing object disappears within the range of the video camera, indicating that the monitored field has changed, such as a person entering or an object being stolen, the processor 111 may trigger a signal to operate the video camera 110 again.

The wireless communication unit 130 is electrically connected to the processor 111 of the camcorder 110, and is used for transmitting the video electrical signal (or file) from the processor 111 to an external receiving device, and transmitting the instruction from the receiving device to the processor 111 for processing. The receiving device may be a remote server or a smart phone in a cloud architecture, or may be a device for receiving control in a peer-to-peer mode. Therefore, the wireless communication unit 130 may be a Wi-Fi transmission unit, and is in communication connection with the server or the smart phone through the AP sharer; or a Bluetooth transmission unit, and directly interfaces the device for receiving control.

The memory card slot 140 is mounted on the printed circuit board 100 and electrically connected to the processor 111 for accessing a memory card inserted therein. Preferably, the memory card is a micro-SD memory card so as to make the overall size of the network camera module as small as possible. The light supplement unit 150 is mounted on the printed circuit board 100 and electrically connected to the processor 111, and is turned on when the camcorder 110 is turned on, and turned off when the camcorder 110 is turned off, so as to provide a light source required for the operation of the camcorder 110. In practice, the light supplement unit 150 may be a light emitting diode. Preferably, the light emitting diode may have a specific spectrum, such as an infrared light emitting diode. The sound receiving unit 160 is electrically connected to the processor 111, and is configured to record a background sound of the surrounding environment, and further enable the processor 111 to mix the synchronously received video electrical signals to form a video electrical signal or a file with the background sound.

The power management unit 170 is electrically connected to the camcorder unit 110, and provides a portion of the received power to the electrical connection elements thereof. In the embodiment, the power management unit 170 is electrically connected to the radar detection unit 120, the wireless communication unit 130, the memory card slot 140, the light supplement unit 150, and the sound receiving unit 160. That is, the power management unit 170 is a device that allows the network camera module 10 to operate, and may be in the form of an integrated circuit or formed by active and passive devices and switches in the prior art, which is not limited by the present invention.

It should be noted that, although all the above components are on the same printed circuit board 100, according to the spirit of the present invention, when the network camera module 10 is to be installed in a network camera with a narrow internal space, besides the necessary components, such as the camera unit 110 and the radar detection unit 120, which must be disposed on the printed circuit board 100, other components can be disposed on another independent printed circuit board, and the two printed circuit boards can be electrically connected by wire bonding or wire arrangement. Not limited to that depicted in fig. 1.

In addition, two kinds of network cameras using the network camera module 10 are proposed in the present new form, and will be described below.

Please refer to fig. 3, which is an exploded view of a network camera 1 according to another embodiment of the present invention. The network camera 1 includes a network camera module 10, an ac-to-dc module 11, a power adapter unit 12, a lower housing 13 and an upper housing 14. The ac-to-dc module 11 is electrically connected to the power management unit 170, and can convert the received ac power into dc power and provide the dc power to the power management unit 170. The ac-dc module 11 can receive a voltage in a specific range, such as 110V to 240V, and output a dc current with a stable working voltage and current. The power adapter unit 12 includes an electrical connector 12a and an internal power transmission terminal set 12 b. The electrical connector 12a can be connected to an electrical outlet that meets the mains output specification. In this embodiment, the electrical connector 12a is a screw cap. For application, the electrical connector 12a may also be a connector-type socket or a plug-type socket. The internal power transmission terminal set 12b is electrically connected to the electrical connector 12a and the ac-to-dc module 11 for transmitting the ac power from the electrical output socket to the ac-to-dc module 11. In the present embodiment, the internal power transmission terminal set 12b is a metal connecting socket and its connecting wires fixed below the lower housing 13 and rotatably connected to the electrical connector 12 a. The lower housing has two open ends (a first open end for connecting a connection cable 11a of the internal power transmission terminal set 12b with the network camera module 10, and a second open end for exposing a portion of the internal power transmission terminal set 12 b), and the ac-dc module 11 is fixed inside, and further the network camera module 10 is fixed at the first open end, and the electrical connector 12a is fixedly connected to the second open end. The upper housing 14 is detachably coupled to the first opening end to partially cover the network camera module 10, and has a main opening 14b for exposing the lens 14 of the network camera module 10 to focus light emitted from a part of the light sources in the direction of recording images, and a plurality of auxiliary openings 14a, such as openings for inserting a memory card into the memory card slot 140 in the present embodiment.

It should be noted that the metal has a shielding effect and blocks the reflected electromagnetic wave to be received by the receiving antenna 101 or the electromagnetic wave emitted by the transmitting antenna 102, so the upper housing 14 should be made of a non-metal material, such as plastic, metal, wood, etc. In addition, as can be seen from fig. 3, the overall appearance of the network camera 1 is a bulb, and the form of the electrical connector 12a is a screw type lamp cap, so that the lower shell 14 can be produced by using a mold of the bottom of the existing bulb, thereby reducing the cost; and the lamp holder can be installed and operated on site, so as to save the trouble of erecting power lines.

Another embodiment of the present invention is shown in fig. 4. The network camera 2 includes a network camera module 10, an ac-to-dc module 21, a power adapter unit 22, a lower housing 23, an upper housing 24 and a decorative cover 25. Although the ac-dc module 21 and the ac-dc module 22 have different appearances, they have the same functions, and are not described herein again. The ac-dc module 21 is connected to the network camera module 10 by a connecting cable 21 a.

The power adapter unit 22 includes an electrical connector 22a and an internal power transmission terminal set 22 b. In this embodiment, the electrical connector 22a and one of the power transmission terminal groups 22b are fixedly combined, rather than being detachable as in the previous embodiment. The electrical connector 22a can be connected to an electrical outlet conforming to the commercial power output specification, but in this embodiment, the electrical connector 22a is a plug type, such as a two-hole plug, a three-hole plug or a T-shaped plug, which can be directly plugged into a common commercial power socket. The function of the internal power transmission end group 22b is also as described in the previous embodiment and will not be described again. The lower housing 23 also has two open ends, a first open end 23a and a second open end 23 b. The lower housing 23 fixes the ac-dc module 21 inside, fixes the network camera module 10 at the first opening end 23a, and movably connects the electrical connector 22a to the second opening end 23 b. That is, the included angle between the direction of the electrical connector 22a plugged into the commercial power socket and the direction of the recorded image can be adjusted according to the actual use condition, so that the usable range of the network camera 2 is increased. The upper housing 24 can be detachably coupled to the first opening end 23a to partially cover the network camera module 10, and has a main opening 24b for exposing the lens 14 of the network camera module 10 to focus light emitted from a part of the light sources in the image capturing direction, and a plurality of auxiliary openings 24a, such as the auxiliary opening 24a for exposing the control button 170 in the present embodiment, but a part of the auxiliary openings 24a is formed on the lower housing 23. Compared with the previous embodiment, the present embodiment may additionally have a modification cover 24. As the name implies, the cosmetic cover 24 is intended to make the appearance of the network camera 2 more beautiful, and is therefore also limited in the same way as the upper case 24: the material cannot be metal, and has an opening 25a for exposing the lens 14 of the network camera module 10 to focus light emitted from part of the light source in the direction of the captured image.

The network camera 2 in this embodiment may be further modified as follows to make the network camera 2 more operable. Please refer to fig. 5. Fig. 5 shows that the electrical connector 22a further includes an extension line 22c connected to the internal power transmission terminal set 22 b. Thus, the network camera 2 can obtain a far power source, and the layout range is wider.

The foregoing description is intended to be illustrative rather than limiting, and it will be appreciated by those skilled in the art that many modifications, variations or equivalents may be made without departing from the spirit and scope of the invention as defined in the appended claims.
