Description
Technical field
The utility model relates to a kind of camera, and more particularly, it relates to a kind of true and false camera.
Background technology
Camera (CAMERA) is also called camera computer, computer eye, electronic eyes etc., is a kind of video input apparatus, is applied to video conference widely, the aspects such as tele-medicine and monitoring in real time.Common people also can to carry out at network each other by camera having image, have the talk of sound and communication.Camera is except for communication of chatting, also be widely used in monitoring the criminal case fields such as antitheft, play an effect helping public security organ to understand criminal's information and deterrence criminal, existing camera is generally divided into: dome type camera has protective cover, and gunlock then needs to configure in addition protective cover.The zooming range of dome type camera is general all little, such as 2 times, 3.6 times etc., and camera lens is generally all not easily changed.The zooming range of gunlock then depends on the camera lens selected, can from several times to tens times not etc., and the replacing ratio of camera lens is easier to.Dome type camera is mainly used in the monitoring of field of excursion, such as staircase, passage, elevator cage etc.The range of application of gun type camera is then more extensive, and according to the difference selecting camera lens, can realize remote monitor or wide-angle monitoring, the occasion of application is also wide than hemisphere.
But universal all the more along with gun-type camera, criminal is basic understanding operation principle also, so a lot of criminal can carry out " setting foot-point " before crime, to understand the position of camera setting and to monitor blind area, recycling monitors to commit a crime in blind area, is just often stolen in central commodity wholesale and retail markets, city, 9 days-Los Angeles September in 2014 businessman, and monitoring camera is installed by part businessman, still because cause huge economic loss.And also of common occurrence in the situation that China is similar, although there is the camera can turning angle lens, during the shot change of this camera, burglar directly can find that situation turned by its camera lens, thus makes a response.
At present, on market (application number be 201120335138.9 Chinese patent disclose a kind of anti-theft vidicon with camera), this video camera also can provide a kind of blind area function for monitoring, but because video camera has two camera lenses, but secondary camera can not use in the ordinary course of things, required data bandwidth, memory space, capital increases greatly, and need to arrange an output picture over the display more, too increase the burden of monitoring personnel, so this video camera improves the cost of monitoring undoubtedly.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide the true and false camera of one that can need to monitor according to user blind area.
For achieving the above object, the utility model provides following technical scheme: a kind of true and false camera, comprise housing, it is characterized in that: described housing is provided with primary mirror and auxiliary minute surface, in described housing, be movably set with the camera lens that can switch between primary mirror and hidden minute surface.
By such setting, the camera lens of camera just can be rotated in camera by fixed lever, if user needs camera rotary alignment primary mirror, the exposed part in outside of camera lens can be passed through, main lens is aimed at the visual angle of rotating lens, open video camera again, user just can see the content that primary mirror direction shows, thus monitor, camera blind spot is utilized to carry out the burglar stolen if user meets with, or when other situations need to monitor camera bottom, the exposed part in outside of rotating lens can be passed through in advance, turn visual angle to auxiliary minute surface, so, user just can monitor the situation of camera bottom by auxiliary view, not only play an effect monitored, attachment lens only can turn the monitoring cost that can also ensure video camera when needs.
The utility model can be set to further: described camera lens is provided with fixed lever, one end of described fixed lever is fixedly connected on camera lens, the other end is rotatably connected with housing, the inwall of described housing is provided with auxiliary minute surface, described auxiliary minute surface is positioned at immediately below camera lens, and described housing is provided with opening, and described opening is located at directly over auxiliary minute surface, the part of described camera lens is exposed to outside by through hole, and described camera lens rotates by fixed lever.So, just can produce the above-mentioned effect of turning camera lens, and structure is simple, is easy to realize.
The utility model can be set to further: described fixed lever is connected with rotary position-limit mechanism.
By the setting of rotary position-limit mechanism, cam lens can be made more stable when rotated, there will not be shake lamp situation to cause picture unclear.
The utility model can be set to further: described rotary position-limit mechanism is included in described fixed lever and is all fixed with travelling gear, described travelling gear engagement is provided with fan gear, described housing is rotatably connected limited location bar, described fan gear fixed cover is located on gag lever post, the part of described fan gear is provided with the gear teeth, the part that described fan gear does not arrange the gear teeth is provided with projection, and described position-limit mechanism inside is provided with limited impression, and described projection is rotationally connected with limited impression.
The rotation to camera lens is completed by the engagement of travelling gear and fan gear, user dials through the module on camera top, play the effect that rotates adjustment camera lens monitoring direction, the gear teeth of fan gear only cover the quadrant of fan gear, the projection of fan gear is corresponding with endless belt-shaped groove to be arranged, ensure that camera lens can only rotate between primary mirror direction and auxiliary minute surface direction, play a good position-limiting action.
Compared with prior art, the utility model has the advantage of: main lens visual angle can be made as required to change between primary mirror and auxiliary minute surface, only need to arrange a camera head monitor interface, just can play the switching to primary mirror visual angle and auxiliary specular view, the supervision to camera blind area more popular on market can be completed in the unwitting situation of stealer, play a good anti-theft effect.
