Summary of the invention
The utility model embodiment provides a kind of web camera, can monitor on a large scale through the wide-angle imaging head, can carry out part through long burnt camera and monitor, thereby when being implemented on a large scale global monitoring, can carry out local key monitoring.
A kind of web camera; Comprise master controller, first camera and second camera; Master controller is provided with first video input interface and second video input interface, and the video output interface of first camera and second camera links to each other with second video input interface with first video input interface respectively, and first camera is long burnt camera; Second camera is the wide-angle imaging head, and master controller also is provided with the output interface that is used for sending to network vision signal.
Preferably, first camera and second camera towards identical.
Preferably, first camera is the camera that is provided with The Cloud Terrace.
Preferably, master controller is provided with the first control signal output interface, and the control signal input interface of first camera links to each other with the first control signal output interface.
Can find out that from above technical scheme the utility model advantage is: in global monitoring on a large scale, can carry out local key monitoring.
Embodiment
Below enumerating embodiment is elaborated to the utility model.
As shown in Figure 1; The utility model embodiment provides a kind of web camera; Comprise master controller 101, first camera 102 and second camera 103, master controller 101 is located in the housing 108, and master controller 101 is provided with first video input interface 104 and second video input interface 105; Said first camera and said second camera are respectively equipped with video output interface separately; The video output interface 106 of first camera links to each other with first video input interface 104 through first connecting line 109, and the video output interface 107 of second camera links to each other with second video input interface 105 through second connecting line 110, and first camera 102 is long burnt camera; Second camera 103 is the wide-angle imaging head, and first camera 102 and second camera 103 are shared master controller 101.Because first camera 102 adopts long burnt camera, is used to take the video image in the close limit, second camera 103 adopts the wide-angle imaging head, is used to take the video image of wide region.Master controller 101 is provided with the output interface 111 that is used for sending to network vision signal, and master controller sends to network through output interface 111 with the video image of first camera 102 and 103 collections of second camera.Therefore, the web camera of present embodiment is that two cameras are shared master controllers, can gather the video image in the different range simultaneously, in global monitoring on a large scale, can emphasis carry out part and monitor.The web camera of present embodiment can also be sent to user terminal through network with the video image of two camera collections.This network can be local area network (LAN), also can be the internet.
Preferably, first camera and second camera towards identical.Be web camera, can gather the video image of same direction different range simultaneously.
Preferably, first camera is the camera that is provided with The Cloud Terrace.Master controller is provided with the first control signal output interface, and first camera is provided with the control signal input interface, and the control signal input interface of first camera links to each other with the first control signal output interface.First camera receives the control signal that master controller sends through the control signal input interface, and control signal is used to control the rotation of the first camera The Cloud Terrace, thereby realizes the rotation control of master controller to first camera.For example, master controller rotates control signal through the first control signal output interface to the first camera output cycle, makes first camera in an angular range, carry out the cycle rotary scanning, gathers the video image of the far range of different angles.
In concrete the application, the scope of wide-angle imaging head monitoring is big, but the image of the concrete things that in screen, shows is less, and the scope of long burnt camera head monitor is narrower, but the image of the concrete things that in screen, shows is bigger.The utility model has combined the characteristics of wide-angle imaging head with long burnt camera, when using the wide-angle imaging head monitoring overall situation, uses long burnt camera to carry out the part monitoring.When the monitor staff sees the subrange in the global monitoring image through monitoring screen in, abnormal conditions being arranged, can adjust the position of long burnt camera, monitor this subrange, make the monitor staff can on screen, see the bigger image of subrange more clearly.Certainly, meanwhile, can also continue to proceed the large-range monitoring of the overall situation through the wide-angle imaging head.
More than a kind of web camera that the utility model provided has been carried out detailed introduction; For one of ordinary skill in the art; Thought according to the utility model embodiment; The part that on embodiment and range of application, all can change, in sum, this description should not be construed as the restriction to the utility model.
